Fuel Management

Without a means of measuring fuel flow, you must rely on the aircraft fuel gauges or total time of flight. Aircraft fuel gauges are notoriously inaccurate (they are only required by the FAA to read accurately when displaying empty). And measuring time of flight is only an approximation, and assumes a constant fuel flow rate for each phase of flight.

The FS-450M Fuel Scan uses small turbine transducers that measure the fuel flowing into each engine. Higher fuel flow causes the transducer turbine to rotate faster which generates a faster pulse rate. Because the transducer turbine generates thousands of pulses per gallon of fuel, it can measure with high resolution the amount of fuel that the engines have consumed. Prior to engine start you inform the FS-450M Fuel Scan of the known quantity of fuel aboard, and it will keep track of all fuel used.

For fuel calculations to be accurate, it is imperative that you inform the FS-450M of the correct amount of fuel aboard the aircraft. Do not rely on fuel flow instruments to determine fuel levels in tanks. Refer to original fuel flow instrumentation for primary information.

Section 2 - Displays and Controls

The FS-450M helps you manage your fuel. There are two components of the user interface:

• Digital display for numeric readouts and messages: top display

is fuel flow per hour and the lower display for all other parameters.

• Two front panel operating buttons:

Section 3 - Modes and Alarms Modes

There are two standard operating modes of the FS-450M: Automatic Indexing, and Manual Indexing. Most of the time you will operate the FS-450M in the Automatic indexing mode. When you first turn on the power the FS-450M starts in the Manual indexing mode, but will enter the Automatic indexing mode after a minute. Tapping the AUTO button will begin the Automatic Indexing Mode.

Alarms

The FS-450M has programmable alarms. When the remaining amount of fuel falls below the alarm limit the lower display will show the amount of fuel REMaining and REM will flash on the lower right display.

When the remaining time falls below the alarm limit the lower display will show the MINutes of fuel remaining and HRMN will flash on the lower right display.

When an alarm is displayed, tapping the STEP button will temporarily disable the alarm indication for the next ten minutes.

When an alarm is displayed, holding the STEP button until the word appears will disable that alarm indication for the

remainder of the flight.

Section 4 - Operation Diagnostic Testing on Startup and During Flight

When your FS-450M is first turned on, all digits light up in each display for a short time, permitting you to check for non-functional segments. Then the FS-450M tests internal components, and integrity of the system.

Page 4 FS-450M Fuel Scan

Start Up Fuel

After initial self-test, you will be asked to inform the FS-450M of start up fuel. The FS-450M will display

(or LITERS or POUNDS)

for one second, and then flash . During flight you may also inform the FS-450M of startup fuel

using the pilot program mode, beginning on page 8, if you forgot to do so at start up.

Refer to the column in the chart below corresponding to your fuel tank configuration. Tap the AUTO button to select one of the four following fueling choices on the left column of the chart.

If your aircraft has tank fill tabs and no auxiliary tanks, you can use the auxiliary tank feature to select either filling to the tank tabs or topping the tank. See “Main Tank Capacity” and “Auxiliary Tanks” beginning on page 15 to program the FS-450M for this feature. The FS-450M does not differentiate fuel flow between the main and auxiliary tanks; it considers only total fuel in the aircraft.

If you added less than full fuel, then tap AUTO to select

. Then tap STEP. The next display will ask

you how much you added: (or selected units). Hold the AUTO button to count up, tap the AUTO button to count down. The count up will stop at full tanks, since you cannot add more fuel than would top the tanks. Tap STEP to complete the entry and advance to the Manual indexing mode.

If you removed fuel from the aircraft or wish to correct the total quantity of fuel on board, you can “add” a negative amount of fuel.

Page 6 FS-450M Fuel Scan

Accumulate Total—Trip Total

You may either display total fuel used

• since the last time you informed the FS-450M that the

aircraft was refueled, or

• for an extended trip with multiple fuel stops.

This selection affects only the USed parameter, . How to select whether to accumulate for a extended trip or reset at each refueling is described in “Pilot Programming” beginning on page 8.

Resetting “USed”

Every time you inform the FS-450M that the aircraft is refueled, the amount of fuel used is set to zero, unless the instrument is programmed to accumulate for an extended trip. The display of fuel used pertains only to the fuel used since the last time you informed the FS-450M that the aircraft was refueled.

In the manual mode with left and right engine USed displayed, holding the AUTO button for three seconds will reset the left, right and total used to 0.

Parameter Indexing

The FS-450M steps through the engine parameters in a specific sequence. Listed below is the indexing sequence, parameter description and example of the digital display. The display will pause at each parameter for a few seconds in the Automatic indexing mode. In the Manual indexing mode, tap the STEP button to advance to next parameter. Holding the STEP button will display the previous parameters in the sequence (rapidly backwards).

For Your Safe Flight Page 9

Start Up Fuel

During flight you may also inform the FS-450M of startup fuel using the pilot program mode. See page 5 for the steps to take to set the start up fuel if you did not set it during power up.

Indexing Rate

In the automatic mode the display will automatically index through each parameter and pause for a period of time. The pause time can be set from between 1 and 9 seconds. Set the rate to 0 to inhibit the automatic indexing mode.

Fuel Flow Parameters

The pilot may set three parameters:

• K Factors—the fuel flow transducers calibration constants.

• Accumulate for extended trip—default is OFF: reset the fuel

used to 0 every time you inform the FS-450M that the aircraft was refueled. With accumulate ON fuel used will not be reset to 0 when you inform the FS-450M that the aircraft was refueled.

• GPS Communications fuel data format.

K Factors

The K factor is shown on each fuel flow transducer as a four digit number, which is the number of pulses generated per gallon of fuel flow. Before installing the transducer, write down the K factors here: Left_________ Right________. To enter the number, move the decimal point three places to the left. For example if the K factor on the fuel flow transducer is 29,123, enter 29.12 in the K factor parameter.

The K factor can be changed in the pilot programming procedure. When the K factor is changed during a trip, calculations of fuel

Page 10 FS-450M Fuel Scan

used, fuel remaining and time to empty are not retroactively recalculated.

Fine Tuning the K Factors

The K factor shown on the fuel flow transducer does not take into account your aircraft’s particular installation. Fuel hose diameters and lengths, elbows, fittings and routing can cause the true K factor to be different from that shown on the fuel flow transducer.

Setting the K factors Use the following procedure to determine the new K factors.

1. Make at least three flights of about two to three hours each. Note the actual fuel used (as determined by topping the tanks) and the FS450M calculation of the fuel consumed for each flight = USD L and USD R.

Fuel Measurement Units, Fuel Capacity, Alarm Limits

Fuel Measurement Units

Selects the units in all parameters where fuel quantity or fuel rate is displayed. If you change this parameter, it does not change the numerical value of the fuel tank capacity. You must do this manually. For example if you change from gallons to pounds, the tank capacity will be interpreted as 50 pounds rather than 50 gallons; the FS-450M will not convert 50 gallons to equivalent pounds.

Main Tank Capacity

Enter the total capacity of the main tanks in the fuel flow units selected. If you have tank tabs (but no auxiliary tanks) and sometimes fill only to the tabs, set the main tank capacity to the capacity up to the tabs.

Auxiliary Tanks

If you do not have auxiliary tanks or tank tabs, answer “No.” If you answer “Yes,” you will be asked to input the capacity of the auxiliary tanks in the fuel flow units selected. If you have tank tabs and sometimes fill only to the tabs, set the auxiliary tank capacity to the difference between full tank capacity and tab capacity. The FS-450M does not differentiate fuel flow between the main and auxiliary tanks; it tracks only total fuel in the aircraft.

Low Time Alarm Limit

Select the value of the time remaining, in minutes, that triggers the alarm. Time remaining is calculated at the current fuel flow rate.

Low Fuel Alarm Limit

Select the value of the fuel remaining, in the selected fuel flow units, that triggers the alarm. Fuel remaining is calculated at the current fuel flow rate.

For Your Safe Flight Page 15

Carburetor?

Different response filters are used depending on whether your engines are carbureted or fuel injected. The filters for a carbureted engine have a slower response time to reduce sudden fluctuations in readings. Select FILTR=1, 2 or 3 where higher number is more smoothing. Pick the lowest number that gives steady readings.

Flow Only

If you want to display only fuel flow, TOTaL and USed without any alarms and without displaying HRMN, REQ, RES, MPG and

REM, enable the flow only setting. To do this, when you see END Y at the completion of the setup procedure, simultaneously hold the STEP and AUTO buttons for five seconds. You will see FLOW ONLY? N. Change the N to a Y by tapping AUTO. Then tap SET to exit.
