NOTE: This system is not FAA
approved.
It is intended for installation
in Experimental category aircraft only.
Not just another voice alerting system, its
safer because it requires pilot interaction
Can be activated by either
airspeed or flap position.
The P/N 2080 Gear Position System is an
electronic system that provides voice warnings if the landing
gear is not in the correct position for both a water landing and
a runway landing. The system consists of a small box that can be
mounted anywhere behind the panel, and 2 pushbutton switches
with built in lights. The switches are labeled "L" for land and
"W" for water. The system connects to the aircraft Pitot system.
When the airspeed exceeds a preset value, the system becomes
active. A 15 sec delay is built into the system to prevent false
triggering on takeoff. The activation speed can be set to any
value between 45mph and 90 mph by a simple screwdriver setting.
Once activated, the lights illuminate for 6 sec to indicate that
the system is active. If the airspeed falls below the activation
speed, the pilot will hear the voice message "SELECT LANDING" in
his headset and through the built in speaker. He must then
select either the "L" or the "W" switch depending on which type
of landing he is making. Once the landing has been selected, the
system checks the gear position to determine if the wheels are
in the correct position for the type of landing that has been
selected. If the gear is correctly positioned, he will hear the
voice message "GEAR OK FOR WATER LANDING" or "GEAR OK FOR RUNWAY
LANDING". If the gear is not correct, he will hear "CHECK
LANDING GEAR" in his headset and through the built in speaker.
The system can also be activated by lowering the flaps at any
speed. Lowering the flaps will start the landing sequence by
initiating the select landing voice. Raising the flaps or
increasing the airspeed will return the system to the flight
condition. The system can also be tested in flight or no
the ground. Pushing either switch will start a self test of the
electronics. If the system is working, the pilot will hear the
message "TEST OK". The system can be disengaged for slow flight
by pushing and hold either switch for 2 sec. When released, the
lights will flash indicating that the system is temporarily
disengaged. Pushing either switch again re-engages the system
and turns the lights off. The system interconnects to the
existing aircraft gear position lights, and can function in
aircraft having 2, 4, or 8 position lights The unit comes
complete with a prewired cable assembly and switches.
Total system weight is less than 1 lb.
