OPERATION OF THE BASIC FLIGHT INSTRUMENT

As with our autopilot products, extensive attention has been given to providing the simplest operation. No sequential pressing of buttons is required to reach basic control functions and no additional button pressing is required to set values. Starting with a clean sheet of paper the layout of controls (two knobs and five soft keys) is sufficient to handle all EFIS and built in autopilot control functions.

On the basic flight instrument, the right hand knob is primarily dedicated to setting the barometer and the left hand knob is primarily dedicated to setting the direction bug. Pressing the ALT soft key sets the altitude bug to the 100 foot mark nearest the present altitude. This setting is entered into the active state by pressing the right hand knob. If the intent is to select an altitude the ALT button is pressed and the right hand knob is rotated to select the desired altitude. (With the knob out, steps are 500 feet and with the knob depressed, steps are 100 feet.) When the altitude has been set, press the knob to ENTER the value. It will be noted that when any value is to be set a screen showing the selection to be made will appear above the appropriate knob.

When the aircraft is within 30 miles of the destination fix, the CRS label will display on the soft key at the far left. To select an arrival course different from the enroute course on the HSI press CRS and then rotate the left hand knob. When the course is set press the knob to ENTER. A computer generated arrival procedure in which steering from the enroute course to the selected runway is described in the special functions section.

Just above the left knob is the label [DIM] in small print. To set the dimmer, press and release the knob, then rotate to set the desired light intensity. When this is done, press and release the knob to exit the set mode.

When there is NO GPS the directional gyro operates in the free gyro mode, and the label above the far left soft key is SET DG. When this button is pressed, the left knob is used to set the DG to the magnetic compass. As is the case with any free gyro this procedure is to be repeated periodically as required.

OPERATION OF THE EFIS PILOT

When the autopilot is not engaged operation and labels are the same as the basic EFIS except for the presence of the AP button. When the autopilot is engaged, the right hand knob is dedicated to selecting vertical speed. The [BARO] label is now just above the right knob. To adjust the barometer, press and release the knob to enter the Baro set mode, and then rotate the knob, press and release the knob to ENTER. The button to the left of AP is labeled with NAV or GPSS. This mode is turned on or off by pressing the knob. Rotation of the directional knob also turns off the NAV or GPS mode. When GPSS mode is engaged GPSV appears above the button to the right of AP. Further information on GPS steering is in the special functions section.

Mechanical Installation Considerations

PROGRAMMER INSTALLATION

Mounting Considerations The EFIS Series unit is designed to mount in the aircraft instrument panel within view and reach of the

pilot. The primary unit location should minimize pilot head movement when transitioning between looking outside of the cockpit and viewing/operating the EFIS Series unit. Maximum recommended viewing angle should be no more than 20 deg. The maximum mounting angle the EFIS can accommodate is 12 degrees longitudinal axis and 0 degrees lateral axis. The location should be such that the EFIS Series unit is not blocked by the glare shield on top, or by the throttles, control yoke, etc. on the bottom. Use aircraft installation standards for mounting and support of the EFIS programmer.

Wiring Considerations Use AWG #24 or larger wire for all connections unless otherwise specified. The standard solder pin

contacts supplied in the connector kit are compatible with up to AWG #18 wire. In cases where some installations have more than one component sharing a common circuit breaker, sizing and wire gauge is based on, length of wiring and current draw on units. In these cases, a larger gauge wire such as AWG #20 may be needed for power connections. Do not attach any wires to the outside of the EFIS or route high current wires within six (6) inch of the programmer. Ensure that routing of the wiring is not exposed to sources of heat, RF or EMI interference. Check that there is ample space for the cabling and mating connectors. Avoid sharp bends in cabling and routing near aircraft control cables. Do not route the COM antenna coax near any EFIS components.

RFI/EMI considerations

The EFIS programmer is shielded and does not generate any appreciable level of electromagnetic interference. Moreover, the servo lines (except for power and ground) are low-current and cannot contribute to RF interference. The servo power and ground lines do have switching currents through them, but so long as there are no parallel runs of servo power and ground lines with such things as poorlyshielded antenna lines or strobe light power lines, there is no need to shield the servo harnesses. The EFIS itself has been internally protected from RF interference and has been test ed under fairly extreme conditions, such as close proximity to transmitting antennas. However, it is always good practice to insure that such antennas are properly shielded and not routed directly over or under sensitive panelmounted electronic equipment. Most problems in this area are the result of improper RF shielding on transmitting antennas, microphone cables, and the like. The most sensitive input to the autopilot is the Control Wheel Switch input. This line should not be routed in parallel with transmitting antennas or other sources of known RF interference. The CWS wire should be shielded with the shield connection to pin 19 of the autopilot connector or a close suitable ground point.

Pitot and Static Connections

The TruTrak EFIS require connections to the Pitot and static lines, see page 8. The preferred method of this connection would be tee fittings near the aircraft’s airspeed indicator. The importance of a good static port and line cannot be overstated. In some cases, problems can be caused by having a large number of devices connected to a single, insufficient, static port. In other cases, the static line itself is adequate but there are one or more devices connected to the same line, one of which has a large static reservoir. A simple remedy for this problem if it occurs is a tee-fitting near the static port, and a dedicated line to the EFIS only or a dedicated static port close to the autopilot. Obviously, an insufficiently-large orifice coupled with large static reservoirs can aggravate the problems associated with lag.

Servo Installation

The installation information in this section is extremely important and must be clearly understood by the installer. Improper servo installation or failure to observe and diagnose installation problems prior to flight can result in extremely serious consequences, including loss of ability to control the aircraft. If there are any questions on the part of the installer it

is mandatory to resolve these questions prior to flight of the aircraft.

Most modern experimental aircraft use push-pull tubes to drive the primary controls. These tubes generally have a total travel of 3” or less; therefore, it is best to connect the autopilot servo to the primary control by the same method. This connection consists of an arm on the servo connected by a push-pull rod to the primary control. Rod-end bearings are required on each end of the push-pull rod. The servo arm must not rotate even near to the point called OVER CENTER, the point at which the primary aircraft control would lock up. Some aircrafts mechanical primary control installations will not allow this to occur and do not need the servo stops. This is a condition that would result from the servo being back driven when the pilot operates the controls, or from the servo itself driving the controls to a stop. To protect against this mechanical stops are supplied with the servos. These stops are drilled so that they can be mounted at different angles as required (18° intervals)

In addition to the proper use of the stop it is important to know the amount of travel on the primary control that the servo can handle. With the push rod connected to the outermost hole (1 ½”) the travel on the primary cannot exceed 2 ½”, the intermediate hole 2 1/16”, and the inner hole 1 5/8”. It is important to note that at the neutral point of the control the SERVO ARM must be PERPENDICULAR to the push rod, and that the stop must be mounted so as to limit travel as near as possible to equal amounts in both directions. In certain factory-designed installations there may be well-proven exceptions. There will be installations in which space does not permit the use of the stop. When this is done the aircraft’s primary control stops must be positive and care must be taken to be sure that at the neutral point the servo arm is perpendicular to the push rod, and that the travel limits of the servo arm are not exceeded. There are installations in which the travel of the push-pull tube exceeds the allowable 2 ½”. For such installations, the drive can be applied to a bell crank at a radius point that moves the desired 2 ½” of maximum allowed travel in the outermost hole of the arm.

When there is no way to have a drive point of less than 2 ½” or when the primary control is cable-driven it is necessary to use the capstan-cable servo drive. When this is done the servo should be mounted so that the 1/16” diameter cable which wraps around the capstan when extended parallel to the primary cable is approximately 3/16” from the primary cable. If the primary control travel does not exceed 5” the cable locking pin will be 180° away from the point at which the cable leaves the capstan. When the primary control is at the neutral point this means the total cable wrap around the capstan is 360°. If the primary control travel is greater than 5” the cable wrap is 720°and the pin is adjacent to the output point when the primary control is at the neutral point.

The cable clamps when properly installed will not slip and thus get loose, but it is desirable to NICO press or swedge a fitting on to the cable so as to provide added assurance that the cable will not become slack. If the bridle cable is not sufficiently tight there will be lost motion in the autopilot drive. This will result in hunting (oscillation).

THE DISPLAY

Consider first the pitch display. Motion of the pitch display short term is gyroscopic as it must be to fly in IMC. Long term it is VSI. This is a special case of a presentation used in the military called VELOCITY VECTOR. This display has two advantages. The first is that it provides an instantaneous vertical speed presentation. The second is that when the reference airplane is on the horizon the aircraft is neither climbing nor descending. This eliminates the need for adjusting the position of the pitch reference airplane to compensate for the angle the fuselage is flying. The resulting benefit of this concept is that it makes holding altitude easier (not only in straight flight but also in turns). It is a fact that next to AOA, airspeed provides the best warning of approaching a stall. For this reason the airspeed pointer flashes red when a pre-set minimum airspeed safely above a stall is reached. There are critics of this concept who believe that attitude is an indicator of approaching a stall. NOT SO, attitude alone is not at all such an indicator.

The HSI is placed below the horizon as in the larger more expensive displays. It is in the form of an ellipse for two reasons. First, an ellipse when compared with a circle of the same height provides a broader scale at the top where it is read. Second, it looks as a circle would when laid out on the ground ahead of the aircraft. When a DIRECT TO or FLIGHT PLAN is set into the GPS this display becomes an HSI. The boldness of this high quality display in combination with its location enhances the fly ability of the overall instrument. Finally, the HSI contains features that make functions available that are not found in other low cost systems. These are described in other sections.

The analog presentations of airspeed and altitude are based on the belief that in some cases round is better. It will be noted that after having tried other presentations the automobile industry is back to round instruments. Nothing in the modern world of vertical tapes compares with the dynamic effect of a white needle moving around a black altimeter dial. As a target altitude is approached it is natural for the pilot to slow the needle velocity so as to arrive at the altitude without overshoot. The difference is that in this system the dials rotate about fixed pointers, but the relative motion retains the same effect as the moving pointer. In addition, the rotating altimeter dial further enhances the motion factor. To satisfy personal preference the display can be switched back and forth between round and rectangular, even in flight. Of those who have tried both the choices have been almost unanimous in favor of the round.

Within the bank angle scale indicators are inserted which show the angle for a standard rate turn. These indicators move outward on the bank angle scale as airspeed increases. Placed above the bank angle scale is an inclinometer that looks just like a conventional ball in a curved tube.

Still another convenient feature is the optional presentation of important engine data in the pilot’s direct field of vision displayed across the top of the instrument.

Automatic Arrival Transition

In an aircraft tracking a course inbound to a destination airport, the letters CRS will appear above

the far left soft key when the distance becomes less than 30 miles. When CRS is showing, the autopilot can be programmed to fly a transition from the enroute arrival course to a selected arrival course set into the HSI. This is not intended to be used in an IFR approach but instead as a convenience for the low time pilot in arriving at an un-familiar airport or for the over loaded pilot in marginal VFR weather.

To initiate the automatic arrival mode, press CRS, select the desired runway course, and click the APPR button. The autopilot will n

ow fly the entire arrival path to the desired runway. An additional feature of the automatic arrival mode can be used to position the aircraft according to the desired right or left hand pattern. After setting the inbound course press enter instead of APPR to remain in track mode. Once the desired aircraft position is established, press CRS then APPR to initiate the automatic arrival. This procedure works regardless of the direction of the inbound course and that of the selected approach course to the airport.

BARO & TRK SELECTION

In the TruTrak EFIS display, both barometer BARO and direction TRK are set by rotation of dedicated knobs.

DIMMING

Dimming of the display is accomplished by a Click of the left knob [DIM] and then rotating the knob Counter Clock wise to reduce the display illumination. External dimmer input will only control the button illumination.

DIRECTION GYRO

Normally this adjustment will not be necessary, as the HSI will be slaved to a GPS NMEA source. If there is a loss of the GPS source then the internal gyro backup will maintain the DG. Click the soft key (button) beneath SET DG provides a screen for correction of any drift in the DG that may occur by rotating the left knob to set the DG, and then click ENTER. Natural progression will be reduced with repeated DG SET.

ALTITUDE BUG

Click the soft key beneath ALT provides a screen for preselecting the altitude. The GREEN BUG on the altimeter will move to the closest 100 ft mark of the current altitude. Then rotating the right hand knob SELECT ALT will allow the altitude to be selected. Each step of the rotary encoder moves the bug 500 ft. while depressing the knob and rotating provides 100 ft. steps and then click ENTER. The altitude bug will never move out of view but will remain ether at the top of the altimeter to indicate selected altitude is above current altitude or the bottom to indicate selected altitude is below current altitude. The selected altitude setting can always be seen above the SEL or ALT after selection on the display. EFIS AP II will NOT preselect altitude in AP mode.

GPS INFORMATION

The HSI requires GPS NMEA information to function correctly. If the primary serial connection and communication protocols have been setup correctly, the EFIS display will display GPS/HSI information as shown. If not then the Display will show NO GPS and only the DG will be operational. When a flight plan has been entered into the GPS, the HSI will display a Course to the first waypoint. The deviation bar will offset to show the aircraft present position compared to the desired track. The small

yellow diamond shaped bug is the DIRECTION TO WAYPOINT bug. Setting the HSI CRS pointer is accomplished by clicking the soft key

beneath CRS to enter the set up screen. Rotation of the left knob selects the course, click ENTER to set.

All EFIS with RS-232 (NMEA) input will have GPS NAV (NAV) but will overfly the waypoint then intercept new the track at about a 45 degree angle.

The EFIS AP IV has the ability to perform GPSS and GPSV commands from the programming of the GPS unit communicating across ARINC wires to the EFIS AP. The GPSV requires a GPS approach to communicate GPSV information to the EFIS AP IV. Valid information is required to allow the GPSV button to be engaged. When GPSS and/or GPSV are engaged the steering commands come from the flight plan programmed in the GPS. See page 15.

AUTO PILOT SETTINGS

Rotate the right knob NEXT on the first setup page to enter the AP setup pages.

LAT AP VRT AP

ACTIVITY

(Setting range 0 – 36) The velocity at which the servo moves the control surface. The higher the number the more movement you will see in the control surface. With a standard servo (DSB-X, DSP-X) you should start at 0 then work your way up in flight to set the level for your aircraft. The High Torque Servo (DSB-HB, DSB-HC) has a different gear ratio, so an Activity setting of 12 will be equal to about

0. With too low a setting the aircraft will hunt slowly and appear to be lazy. With too high a setting the aircraft will hunt rapidly, and appear nervous and jittery.

MICRO

(Setting Range 0-31) This is used to remove the significant lost motion in the control system, usually a cable control system. Most aircraft do not need this changed from 0. An example of when one might need to adjust microactivity is if flying in still air, there is a very slight wing rock that cannot be solved by adjusting the ACTIVITY setting.

ROLL

(Setting Range 0-4) Most aircraft do not need this changed from 0. Only aircraft type like CT & CUB that have adverse Yaw with turns (rudder assist). We recommend factory assistance before adjusting this value.

BANK

(Setting Range Low – MED – High) This setting limits the maximum bank angle of the aircraft to approximately 13 degrees at the low setting, 18 degrees at the medium setting, and 24 degrees at the high setting.

STATIC

(Setting Range Low – MED – High) This setting is used to compensate for lag in the aircraft static system. This setting is usually not adjusted. This value is used to remove very slow hunting, of more than 15 to 30 feet, in altitude hold when adjusting the activity setting does not solve the problem. This is NOT the setting to adjust if there is slight nose bobble in still air; the setting for that situation is HALF STEP. We recommend factory assistance before adjusting this value.

TruTrak Flight Systems 11 EFIS Autopilot Installation Manual April 2009 8300-057 Rev D

Page 14

HALF-ST

(Setting Range N or Y) This setting will cause the servo to take smaller steps, but will also reduce the torque available. Normally this setting is “N”, if the aircraft nose moves up and down very slightly in VERY calm air, and it can be verified that the servo is only moving one step for each “bobble” of the nose, then select “Y”. Only very light aircraft that are extremely pitch sensitive will need to adjust this setting.

SPEEDS (AP) MIN AS

(Setting Range 0 – 300) This setting is the minimum airspeed in knots that the autopilot will fly the aircraft. Example: If the aircraft is climbing and the power setting is not adequate to maintain selected vertical speed setting, the autopilot will lower the nose until MIN AIRSPD setting is met. The FD “Fly Bar” will also indicate a decent needed and flash red until airspeed is restored.

NOTE: Do not set MIN airspeed setting too low for approach speeds.

MAX AS

(Setting Range 0 – 300) This setting is the maximum airspeed in knots that the autopilot will fly the aircraft. Example: If the aircraft is in a decent and the power is not reduced so as to keep the airspeed below the MAX AIRSPD setting, the autopilot will raise the nose until MAX AIRSPD setting is met.

NOTE: If set too low, aircraft will ascend in high cruise air speed.

Y D

(Setting Range N or Y) This setting indicates if the aircraft has a Yaw Damper system installed.

YAW CENTR

(Setting Range -8 – 8) This setting is used to have the Yaw Damper keep the aircraft slip/skid indicator centered when the Yaw system is engaged. Allow a few seconds for the Yaw System to respond to the new setting.

YAW ACTVTY

(Setting Range 0 – 12) The velocity at which the servo moves the control surface. The higher the number the more movement you will see in the control surface.

AUDIO

(Setting Range 0 – 32) This location turns the audio on or off or controls the volume of the Speech.

Yaw Damper Ground Checkout

For an EFIS with a Yaw Damper, the next step in the checkout procedure is to verify operation of the yaw damper.

Set the YD by clicking the AP button on the EFIS. Note: Any time the autopilot is off in normal flight the yaw damper may be toggled on and off using the YD key, so long as the aircraft is not flying slower than the preset minimum airspeed.

The aircraft should be on a level surface (with its “ball” centered) for this adjustment. With the toggle switch on the YD controller “OFF” for centering (leveling). Adjust the leveling potentiometer (which protrudes from the face of the yaw damper module) to stop the movement of the servo (rudder). Once the proper adjustment is done, switch the toggle switch toward “gyro on”. Push the tail away from you and confirm that the rudder moves in the direction that you pushed the tail (empennage). Press the AP button to disengage the yaw damper, re-enter the YD setup with the above procedure, advance to the and set YD ACTIVITY value to zero. This insures that the yaw damper adjustments do not complicate the first test flight of the autopilot, confirm that the minimum airspeed is set to the desired value for actual flight. This should be an indicated airspeed (in knots) which is safely above the sta or climb out speeds. Make sure that the toggle switch on the Yaw Damper controller is toggled toward “gyro on” for flight.

First Flight

The first flight should be done after having completed all the setup and testing on the ground. For the f

irst

flight, it is important that the GPS unit is properly functioning with the EFIS. The two activity adjustments (LAT ACTVTY and VRT ACTVTY) determine how briskly the autopilot

responds to roll and pitch disturbances. They can be adjusted, in flight, over a wide range; thus the autopilot can be tailored to adapt to any aircraft installation.

Each of the two activity adjustments covers a numeric range of 0 to 36. Unless the value for a pa aircraft is provided by TruT Most installatio

ns would ultimately require somewhat higher settings.

STATIC LAG setting it is set to LOW at the factory but can vary betwe

en LOW, MED, or HIGH to suit a particular static system. LOW value assumes a static system with very little “lag”; the HIGH value assumes a fairly large amount of lag. To diagnose the lag of a particular system, it is necessary to be in the altitude hold mode of the autopilot, prior to setting the STATIC LAG.

Once the autopilot is in altitude hold mode, re-enter the vertical setup mode. In still air, straight and le flight, in altitude hold mode, observe whether the altitude appears to oscillate, or “hunt” slowly up a

vel

nd down. If this is the case, it may be caused by several factors, one of which is the amount of lag in the static system. Increasing the STATIC LAG value to MED or HIGH may cure the problem; however this should be set to the smallest value that satisfactorily flies the aircraft in the pitch axis, as the larger the value the less responsive the autopilot will be to vertical commands or altitude error. Other possible causes of hunting in altitude hold are “lost motion” in the aircraft controls or too low a level of vertical activity setting. Excessive lag in the static system itself can be caused by undersized static ports, improperly placed ports, long static lines, or especially by attached equipment with large static reservoirs. The autopilot can be adapted to cover a wide range of static systems, but in truly extreme cases it may necessary to provide a separate static line for the autopilot so that other equipment attached to the por

does not degrade the autopilot’s performance. Click the right knob twice to return to the MAIN screen.

Yaw Damper First Flight

The Yaw Damper s

ystem requires adjustment of the yaw damper parameters. With the autopilot disengaged, level the aircraft and hand-fly the aircraft in still air. Press YD to engage the yaw damper. Then enter the setup screen for the YD. Select CENTR, Centering is adjustable from -8 to 8 and has enough authority to move the ball approximately one and one half times the width of the ball in either direction. (Coarse adjustment was made using the potentiometer in the yaw damper module during the earlier Initial Checkout Procedure.) Adjust the centering so that the ball is centered. Once the YD LEVELING has been set, click to return to the setup screen. The next field, ACTVTY, determines how aggressively the yaw damper responds to yaw disturbances. Yaw damper activity can range from 0 (off) to 12 (extremely aggressive). For this purpose it is best to find light to moderate turbulence so the effects can be properly observed. Having found suitable conditions, use the knob to gradually increase the value of YD ACTIVITY in order to obtain an appropriate level of response to yaw disturbances. Too hig

h a value will result in rapid oscillation, while too low a value will essentially disable the quick response of the yaw damper to turbulence. Within the acceptable range of operation, there is still room to account for personal preferences. So long as the yaw damper’s ACTVTY value is not so high as to cause oscillation, the response is simply set according to preference

and comfort. Once the ACTVTY has been set, click

the right knob twice to exit the setup mode. The normal operation of the autopilot will turn the yaw damper on any time the autopilot is engaged and

the yaw damper will stay on after the autopilot is disengaged. During final approach and the diminishing of the airspeed below the MIN AIRSPD setting, the yaw damper will automatically disengage. To disengage the yaw damper prior to that point, simply use the YD button to toggle the yaw damper off.
