Cub Crafters CC18-180 Maintenance Manual page 154

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 right wing root panel and the switch is on the leading edge of
the right wing. As the stall condition progresses, the air stream lifts the switch vane, closing the
circuit, and activating the horn.
2. MAINTENANCE PRACTICES
A. STALL WARNING SWITCH ADJUSTMENT
The stall horn should be activated at a speed that is no less than 6 MPH (5.2 kts) 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 27-31-1
(a) Loosen the screws (1) and slide the switch (2) up or down. (Down will cause the
horn to go off earlier and up will cause the horn to go off later.)
(b) Tighten the screws in the desired position and go flying!
(c) See Figure 24-00-1 Standard Electrical Schematic for system details.
