Experimental product not faa certified

 The P/N 2048 Gear Warning system for Experimental amphibian aircraft  consists of a small electronic module (2.5 inch by 3.25 inch weighing less than 1 lb), and a panel mounted switch with light. The system is airspeed activated. The activation speed can be easily set using a screwdriver.

On takeoff once the speed has exceeded the activation speed, the system activates. A time delay is built in to prevent false triggering due to speed fluctuations. The light in the switch illuminates when the system is activated. The pilot can push the switch at any time performing a self test of the system. If the electronics are functioning, the pilot will hear the voice message "TEST O.K." in his headset, and through the built in speaker. Pushing the test switch and holding it for 2 sec. places the system in the disengage mode which temporarily disengages the system for slow flight. During this period, the light in the switch flashes indicating the system is disengaged. Pushing the switch again re-engages the system.

As the aircraft slows for landing, the system enters the landing mode. The light turns off, and the electronics then checks the gear position lights to determine the gear position. If the wheels are retracted for a water landing, the pilot will hear the voice message "WATER LANDING, WATER LANDING" in a female voice in his headset, and through the built in speaker. If the aircraft is making a water landing, the pilot can then push the switch canceling the voice. If the wheels are down, the pilot will hear the voice message "RUNWAY LANDING, RUNWAY LANDING" in a male voice. For multiple light systems, if the electronics determines that all the wheels are not in the same position, the pilot will hear the voice message "CHECK LANDING GEAR, CHECK LANDING GEAR" alerting him of the problem.

If the aircraft has flaps, a flap switch can be added to cause the landing sequence to be initiated whenever the flaps are fully extended. The unit also includes an airspeed activated switch which closes whenever the airspeed is above 45 mph. This can be used to activate a transponder, Hobbs meter etc.

The unit is sold as a complete system including the electronic unit, a pre-made cable assembly, a pre-wired switch, connecters, mounting hardware etc.
