7.11 STALL WARNING SYSTEM
A stall warning horn, located in the left instrument panel, will operate at a minimum airspeed
of 5 kts before a stall. The horn grows louder as the speed approaches the stall speed.
The horn is activated by air from a suction hose that connects to a hole in the leading edge
of the left wing. The hole has a red circle around it. The stall warning hole should be
plugged whenever the aircraft is parked to prevent contamination and subsequent
malfunction of the stall warning system.
NOTE
Use only the factory supplied stall warning plug with the
“Remove before Flight” flag attached.
