3.11.2.1 Ground Test Mode
Use the following instructions to place the unit into Ground Test Mode using the MPC (MAT).
Placing the unit in the Ground Test Mode does the following:
Simulation of heading or track (pointing the traffic on the screen in the correct orientation).
Sets the unit to "In-Air" status allowing Mode C (altitude) output and additional ADS-B output
messages (sent at a higher rate).
o In-Air status also allows Mode C (Pressure Altitude). While on-ground; all calls and Mode C
replies are inhibited.
o This allows the IFR-6000 to test the encoding altimeter input (Mode C).
These procedures assume the following:
Power is being supplied to the aircraft and the unit.
The MPC (MAT) is active on the MPC. Refer to the General Information section, paragraph 1.9 for
details on the correct MPC (MAT) that must be used for specific software release's.
The MPC is connected to the unit via the USB interface
The MPC and unit are communicating. From the MPC (MAT) panel select
ConnectNGT9000USB. This is required each time power is cycled.
1. From the MPC (MAT) panel select Service > Restart Unit in Ground Test. See Figure 3-29.
2. If heading is not being input to the Lynx NGT-9000, then select Ground Test and enter a Simulated
Own Direction (0 – 359 deg.). The own direction is the current true heading of the aircraft. A unit
with a heading input can ignore this step. (Note – A heading input will overwrite a simulated
heading).
NOTES
1. When entering heading information into the IFR-6000 UUT HDG entry field make
sure to enter either the same simulated heading as was entered into the MPC (MAT)
own direction field or the actual aircraft heading (true heading) as appropriate.
2. Determine true heading by adding and East Variation to the aircraft current
magnetic heading or subtracting the West Variation to the aircraft current magnetic
heading (e.g. airport KGRR has a 04W variation so with a magnetic heading of 290
the true heading would be 286). Go to AirNav.com and type in the airport location
to find the variation for that area.
