VEMD H120
This instrument is made for the VEMD hardware made by Sim Innovations, and simulates the VEMD software for the Airbus Helicopters H120 / Eurocopter EC120. The hardware consist of two so called lanes, lane 1 and lane 2. The top lane, lane 1, moves to lane 2 in case lane 1 is turned off or fails.
Lane 1
Power up / boot up
The instrument will power up when a bus voltage of at least 12 volts is present in the simulator aircraft. It will go through a boot cyclus and when the engine is not running present the engine page. If the engine is running, it will continue to the FLI page if all conditions are met.
Engine page
The engine page is shown at start up, until the NG (N1) reaches 60%, after which it will show the FLI page. At shutdown it will revert to the engine page when the NG drops below 60%. When the NG drops below 10% and the rotor RPM below 70 RPM, you will be presented with a flight report.
FLI page
The FLI page is presented when NG reaches 60% or more. The FLI needle shows a combination of several values, combined into one. The maximum FLI value should be normally below 10. The page also shows fuel, NG, T4, TRQ and outside temperature. By pressing the SCROLL button, you can go back and forth to the engine page. In case lane 1 is turned off, the FLI page will move to lane 2.
