OUR GOAL, COMMITMENT AND PASSION
Gear up landings can generally be traced to distractions that occur inside or outside the cockpit during a landing, or the pilots inability to hear and recognize the existing warning system. The P/N 2037 gear warning system is designed to address these reasons, and provide an additional margin of safety against a gear up landing.
The P/N 2037 Gear Alert system is an electronic gear warning device that senses the presence of the ground when landing. If the system determines that the aircraft is close to the ground, and the wheels are still retracted, it provides an instantly recognizable voice warning directly in the pilots headset and through its built in speaker alerting of the problem .The unit also connects to the existing aircraft stall warning system. Anytime the existing stall horn sounds, the pilot will hear a separate voice message in his headset.
The system consists of 3 components, a ground sensing transducer ( approximately 3 inch by 4 ½ inch by 1inch ) that mounts on the belly of the aircraft, a small electronic unit that mounts anywhere in the aircraft, and a small switch that mounts in the instrument panel. Pushing the switch performs a self test of the system. If the electronics are working, the pilot will hear the voice message "TEST OK" in his headset. The ground sensing transducer is a microwave device much like a radar. When the aircraft descends to about 150 ft above the ground, the transducer senses the presence of the ground. The electronics then look at the gear down light to determine if the wheels are up or down. If the system determines that the aircraft is close to the ground and the wheels are still retracted, the pilot will hear the voice message "CHECK LANDING GEAR" in his headset. The system can also be hooked to the existing throttle switch system. Anytime the throttle is retracted with the wheels up, the pilot will hear the warning message. Any time the existing stall horn sounds, the voice message "STALL, STALL" will be heard.
The P/N 2037 Gear Alert system is supplied as a complete system to make installation easier. The installation kit includes a pre-made cable assembly, a pre-wired switch assembly, connecters, and all mounting hardware. The only other part required is a 1 amp fuse or breaker. Total system weight is 1 lb.
