INTRODUCTION

The GE family of Air Data Test Sets (ADTS) provide accurate air data to test two, three and four-channel systems.

The manufacturer has designed this equipment to be safe when operated using the procedures detailed in this user manual.

The required aircraft instrument test values can be entered in either aeronautical or pressure units.

The ADTS will then automatically generate the correct pressure aims for all required channels.

The aircraft air data computer system receives these parameters and calculates altitude, airspeed and angle of attack (if applicable).

ADTS Touch

The ADTS Touch is used to control all required functions. The ADTS Touch can be positioned (docked) on the ADTS or used as a hand held mobile unit via an umbilical cable or using Bluetooth® wireless technology. This allows a person to complete the entire test program remotely while conveniently seated in the aircraft.

The ADTS Touch will have power applied when docked on a powered-on ADTS, or using an umbilical cable connected to a powered-on ADTS, or can be battery powered.

The ADTS Touch is a touch screen device which features a swipe–action (up/down/left/right) touch screen user interface with colour graphics and menus.

DUAL HAND TERMINAL

Dual Hand Terminal

The ADTS553 and ADTS554 can be operated with two hand terminals (either ADTS TOUCH or ADTS TOUCH-ER units). Only one of the units (the ‘Master’) can control the ADTS. The second unit (the ‘Slave’) operates as a display when the Master is connected. The hand terminals can be connected to the controller in three ways:

• Docked (sitting on top of the unit, on the docking connector)

• Via Umbilical Cable

• Via Bluetooth wireless connection.

The allocation of Master and Slave status when two hand terminals are used is shown in the following table:

Configuration Master Slave

Umbilical/Docked Umbilical Docked

Umbilical/Bluetooth Bluetooth Umbilical

Docked/Bluetooth Bluetooth Docked

Bluetooth/Bluetooth Not allowed Not allowed

If one of the hand terminals is connected via Bluetooth, this will always be the Master, and the second unit (either umbilical or docked) will be the Slave. All control parameters and ADTS setting entry shall be disabled on the slave unit. In the event that the Master communication is lost, the slave shall become the master until such time as the link is re-established. The Slave unit can be distinguished from the Master visually, as it includes a “REMOTE” banner on the display at all times when it is in Slave mode:

Pitot Static

When Pitot Static is selected on the dashboard, the resulting screen will clearly display whether the ADTS is currently controlling the pressures at the Ps and Pt ports (CONTROL) or passively measuring the pressures at the Ps and Pt ports (MEASURE).

The condition immediately after power up is always MEASURE, so as to protect any connected systems.

To switch between the two modes, touch the related icon (1) at the bottom of the screen. See also section ADTS Touch

Measure mode

The MEASURE mode screen displays real time Pitot Static parameter measurements (2) based on the current pressures and rates of change (3) of pressures present at the Ps and Pt ports of the ADTS or any connected aircraft systems. All ADTS pumping and pressure control functions are inactive unless Autoleak protection is enabled.

PITOT STATIC

This baseline Pitot Static information screen will typically be used to passively monitor the pressure and leak rate status of the connected aircraft.

Figure 3-5: Measure mode screen - Single Channel

K0553 Revision D 40 [EN] English

Page 50

PITOT STATIC

Figure 3-6: Measure mode screen - Multi Channel

You can switch the system between aero units and pressure units using the toggle control (4).

Control mode

When CONTROL mode is selected at icon (1), the ADTS pumps and pressure control functions are activated but will not cause any change in the current pressures unless requested by the operator.

The CONTROL mode screen also displays real time Pitot Static parameter measurements based on the current pressures and rates of change of pressures present at the Ps and Pt ports. It also has a 'Aim' field for each parameter to allow you to enter new target values for the controller of the ADTS or any connected aircraft systems.

This screen may be configured at icon (2) to accept and present data in either aeronautical or pressure units.

The Pt channel display may be configured at icon (3) to present either CAS or Mach (when in Aero units) and either Qc or Pt (when in Pressure units).

A progress bar (4) indicates rate and percentage completion towards the requested new target aim.

The effort meter (5) can swing left or right according to whether control of the requested pressure for that channel is requiring predominantly vacuum (left) or pressure (right), e.g, an excessive left swing when at an altitude set-point might give early indication of a leak to atmosphere (continuous drain on vacuum pump resource).

- Pt (Pt1, Pt2 on ADTS554)

Displays the currently selected pressure. To change the value, repeat the same procedure as above for Ps.

- Qc (Qc1, Qc2 on ADTS554)

Displays the currently selected pressure. To change the value, repeat the same procedure as above for Ps.

Altitude Dropback

The ADTS550 series products use a single set of pumps to generate the internal pressures and vacuums which are ultimately presented at the Static and Pitot ports. During control situations where high gas flows are required, it is possible for these source pressures to start to collapse. This can manifest itself as an unwanted drop in altitude on a channel that was previously under control and stable.

To prevent this effect, the software inside the ADTS will limit the CAS or Altitude rate changes to maintain a non-ramping (stable) channel within the following limits.

NOTE: In extreme cases the rate limiting effect can make altitude and CAS changes appear very

slow.

MANUAL VENTING OF THE AIRCRAFT PITOT AND STATIC SYSTEMS

ADTS status on power failure

On removal of power, the main output valve linking external ports Pt and Ps to the internal pressure controllers will automatically close. The aircraft pitot and static systems remain safe but with the last applied pressures now isolated and maintained in the hoses.

ADTS status on restoration of power

When power is restored to the ADTS the normal self test routine for the ADTS will be performed and at the end of this the ADTS will exactly equalize the internal manifold pressures to match those of the external aircraft hoses and then the output valves will be reopened. This process will at all times protect the aircraft pitot and static systems from adverse pressure transients, differentials or excessive rates.

When the output valves are fully opened, the normal parameter measurement screens become available from the Dashboard and full control is again available. The testing may then either continue from the same point (when the power failure occurred) or the aircraft pitot and static systems may be safely controlled back to ground pressures.

Actions if power cannot be quickly restored

Two courses of action are possible at this point:

1) Leave the ADTS connected to the aircraft pitot and static systems with pipes safely isolated but maintaining trapped pressures until such time as power can be restored.

2) Use the manual let-down valves on the ADTS front panel to safely bleed the trapped hose pressures back to ambient ground. This must be carried out in a way that ensures the Pt to Ps differential pressure remains at zero while the whole connected system is brought to ground pressure.

Open the valves slowly while monitoring the cockpit gauges for any excessive rate of change.

Independent Pilot / Co-pilot Testing

The ADTS554F can accomplish simultaneous independent control of pilot and co-pilot Ps and Pt and perform a user selectable differential validation between pilot and co-pilot instrument systems

Angle of Attack (Smart Probe) Testing

The ADTS553 and ADTS554 operating in 3 channel mode is primarily designed for Smart Probe validation.

The pitot channel Pt1 is referenced to Ps1 for air speed.

The second static channel Ps2 is used to generate the extra test pressure required for smart probe applications.

Page 90

MULTI-CHANNEL ADVANCED FEATURES

Aims for the 3 channels can be entered manually in the normal method but it is recommended that the test script is used to reduce operator entry error.

Before using the test set the limits must be correctly set for the aircraft under test including the Ps1 Ps2 differential limit.

The ADTS shall process a predefined list of set points from a test Script table. Angle of attack is not calculated and displayed as the calculation differs for each probe.

The Ps2 shall be kept within the Ps1-Ps2 differential limit during ramping and set point control. The control performance of the 2nd static channel is the same as the primary channel.

EXAMPLE BASIC AIRCRAFT TEST OPERATION USING THE ADTS542F

Example Basic Aircraft Test Operation using the ADTS542F

Preparation for Testing

If unfamiliar with the features and functions of the ADTS5XXF then it is important for operators to read and understand the following documents before use:

• Safety and Installation Guide K0554.

• User Manual K0553 (this document).

If the ADTS542F proposed for use has just been delivered, been stored for an extended period or the operability is unknown for any reason, then perform a standard serviceability test of the ADTS before use on aircraft. Details of this test can be found in section Standard serviceability test.

Familiarise yourself with all aircraft specific test requirement s, personal and aircraft safety precautions from the manufacturer’s Aircraft Maintenance Manual (AMM).

Aircraft Connections

Firstly, consider where to place the ADTS base unit such that it can be safely accessed by the operator but also has practical routes for piping to the aircraft ports that will not get knocked or damaged during test operations. This may be either on the hangar/apron floor or a cockpit level gantry.

Any difference in height between the ADTS front panel and the aircraft ports must be configured on the ADTS as an altitude correction (see section Positioning the ADTS). If working on the aircraft outdoors, the signal strength of the radio data link to the ADTS Touch will be optimised if the ADTS is placed with line of sight to the cockpit windows.

Assess the hose lengths that will be required and provision either from the ADTS5XXF delivery kit or from local stores. The ADTS5XXF is supplied with low temperature red and blue flexible hoses at 3m length as standard, but longer hoses may be requested to order. A configurable label kit is provided so that Ps and Pt channel colour coding may be set in line with regional standards. Both of the standard hoses come with ready fitted AN4 size fittings suitable for the ADTS Ps and Pt output ports.

The other end of each hose is open to allow users to fit hose extensions or other pressure adaptors as required.

K0553 Revision D 82 [EN] English

Page 92

EXAMPLE BASIC AIRCRAFT TEST OPERATION USING THE ADTS542F

The direct connections to the aircraft Pitot and Static ports should be made using the adaptor set approved in the AMM, or using equivalents supplied by a specialist port adaptor manufacturer.

We do not recommend the use of improvised connections since this can lead to excessive leakage and potential damage to the aircraft avionics systems.

When all the required pipework has been connected, the ADTS should be turned on as soon as possible to allow a few minutes for it to reach a stable operating temperature. This is a safe action for the aircraft regardless of whether the ADTS Touch is connected or not at this time. No changes in pressure will be applied to the aircraft until actively requested. Make the ADTS Touch data connection to the ADTS, either by Bluetooth® data connection or cable (see section Bluetooth®).

Altimeter and Airspeed Indicator Testing

Limits Protection Checks

The ADTS will automatically power up with the HELICOPTER limits in force. This table enforces the most restricted control range on the ADTS output pressures, so this default configuration is the safest of the predefine limit sets if working on small, low speed aircraft.

Consult the AMM to check the approved maximum test ranges for Altitude, Rate of Climb, Airspeed and Mach for your aircraft

It is important to have the ADTS limits set correctly configured for the following reasons:

a) Prevents operators mistakenly entering test aims which exceed the aircraft maximums.

b) Provides early real time warnings that ranges and rates are being exceeded (due to Pitot Static system leak etc.,).

c) Will prevent inadvertent creation of excessive Mach conditions due to selection of inappropriate altitude and airspeed combinations.

d) Will ensure that the ADTS can successfully reach any extended range test points as required.

[EN] English 83 K0553 Revision D

Page 93

EXAMPLE BASIC AIRCRAFT TEST OPERATION USING THE ADTS542F

Consult the ADTS limits values for the three predefined tables, HELICOPTER, FIXED WING and MAX AERO in the SETTINGS menu (see section Settings). If a suitable protective limits match cannot be found in one of the three predefined tables then choose CREATE NEW LIMITS and edit your own custom limits table name and preferred values from the offered starting values. This protected operation will require use of the Supervisor PIN code. Any attempt to enter limit values greater than the ADTS pneumatic control maximums will create a warning to the user requesting a lower value. Before attempting to create a new custom named limit, first check that there are no more than 4 existing user named tables. A maximum of 5 only are allowed, but old unused tables can be deleted as required.

Leak Checks

Since the leak status of the aircraft is initially likely to be unknown, it is recommended to perform a preliminary assessment at low altitude and airspeed stimulus so as to minimise risk to the aircraft instruments, should a high rate leak be present.

It is strongly recommended to enable the ADTS “AUTO LEAK RECOVERY” function. This will automatically attempt to regain control of the aircraft pressures if the measured rates of change (leak rate) exceed 3000 feet/min or 600 knots/min.

If no specific leak check procedure is described in the AMM, first select safe rates of parameter change for the Ps and Pt channels according to aircraft type. It is suggested to start with simultaneous aims of 2000 feet and 200 knots, following the procedure described for the standard equipment serviceability test described in section Standard serviceability test.

Correct any leak issues found with the hose connections or aircraft systems before proceeding with further testing. The leak status of the ADTS alone may be verified using the procedures in section ADTS leak check.

Typical Aircraft Instrument Performance Checks

The required aircraft specific procedures will be detailed in the AMM but the following generic test is provided purely as an example of how the ADTS facilities might be best utilised.

The ADTS produces controlled altitudes based on the standard sea level pressure (zero feet reference) that is defined in the ICAO international standard atmosphere model. In order to correctly check the aircraft instruments for accuracy against the ADTS, it is vital that the altimeter baroscale datum adjustment is set to the same 1013.25 mbar (29.92 inHg).

Systematically enter the required aims for the Ps and Pt channel from each row of the test table below. Aims may be entered either in aeronautical units or absolute/differential pressure units according to the requirements of the AMM. For each of the six test row conditions, allow the ADTS

to approach and stabilise the aims until the ADTS Touch shows each measurement in green record the difference between the ADTS and the Aircraft instrument under test.

By using the ADTS Touch controls it is possible to present the Ps and Pt channel data for each of the 6 test condition rows in all of the formats shown in the table. By using the settings menu to change either the chosen pressure or aeronautical unit it is very simple to convert the displayed aims and measurement values to the desired format. Such changes can be done without turning off control, so the terminal can effectively also be used as a pressure converter/calculator when designing your aircraft test procedures.

The aircraft status screen can be used to give you a very quick overview of whether the aircraft is climbing, descending or at stable altitude. If you make a mistake with your data entry, use the orange green “hand” symbol to stop ramping and HOLD stable the current pressure, while you consider and correct the intended test point aim. Pressing the now orange “hand” again will release the hold when you are ready. The “Hand” returns to green as ramping to the corrected aim begins again. If the ADTS Touch loses radio link or the cable accidentally becomes severed, the ADTS will automatically enter the HOLD state after 10 seconds. If communications has not been re-established after 10 minutes, then the ADTS will automatically begin a descent to ground pressures.

End of testing

When testing is complete, use the Aircraft status screen to initiate a descent to ambient ground pressure at a safe rate. The rate may be increased or decreased if required from within this screen. To see full parameter details, simply clear the status screen view. It can be recalled at any time. If working with the ADTS.

When the ADTS displays the status as AT GROUND, it is then safe to disconnect the aircraft Ps and Pt connections. The ADTS base unit will also show steady green on the rightmost aircraft status LED when in this state.

ENGINE PRESSURE RATIO (EPR)

Engine Pressure Ratio (EPR)

Engine Pressure Ratio (EPR) is sold as a software product option. Contact GE for more details.

The ADTS may be used to check EPR sensors and indicators. Use Ps (static) for INLET pressure and Pt (Pitot) for OUTLET pressure.

To carry out an EPR check, the display must be showing units of pressure measurement e.g. mbar, inHg.

NOTE: Altitude correction applies to EPR values, make sure this correction does not adversely affect

accuracy. The difference in height between the ADTS and the EPR sensor may be different to the altitude correction previously set for the aircraft instruments.

The EPR function can be operated using one of two methods, as follows:

1) Direct control of Inlet pressure and target EPR value (outlet pressure is auto-set).

2) Direct control of Inlet and Outlet pressure (equivalent EPR aim is auto-set).

The actual method to be used will be specified in the aircraft maintenance manual.

NOTE: The EPR function can only be launched when you have selected ‘Go to Ground’ and the

ADTS is at Ground Pressures.

Setting the EPR - method 1

1) On the “Dashboard”, select “EPR”. The EPR control screen appears.

2) On the EPR control screen, set the toggle control (1) for direct control of Inlet pressure and target EPR value.

6) Enter the desired “Aim” value and touch the “tick” icon. The numbered keypad closes and the previously entered value appears in the “EPR” display.

Wait for the controller to achieve the EPR aim value and inlet pressure. The outlet pressure has now been set based on the inlet pressure and EPR value.

Setting the EPR - method 2

EPR testing can also be performed by specifying the actual INLET and OUTLET values.

1) On the “Dashboard”, select “EPR”. The EPR control screen appears.

2) On the EPR control screen, set the toggle control (1) for Direct control of Inlet and Outlet pressure.
