1. GENERAL
The stall warning system is electrically powered and is made up of a horn and an actuating
switch. The horn is mounted in the left wing root panel and the switch is on the leading edge of
the left wing. As the stall condition progresses, the air stream lifts the switch vane, closing the
circuit and activating the horn.
2. STALL WARNING SWITCH ADJUSTMENT
The stall horn should be activated at a speed that is no less than 6 MPH prior to the stall
occurring in any configuration. On the other hand, the stall warning should not come on so
often that it becomes a nuisance.
Refer to Figure 6.3.20.1
(a) Loosen the screws and slide the switch up or down. (Down will cause the horn to
activate earlier and up will have the horn activate later.)
(b) Tighten the screws in the desired position.
(c) See Figure 5.4.7.1 Electrical Systems Schematic for system details.
