Flaps Fail to Extend

Indications

Flap position indicator fails to move when

change in flap position is selected

Visual confirmation that flaps/slats are up

Procedures - See NATOPS

WARNING: The aircraft exhibits no natural stall

warning during the approach to stall in the EMER

shakers come on at 21.5 units AOA, closely

followed by the stall at 23-25 units AOA.

available will cause the hydraulic fluid to rapidly

overheat, possibly causing a HYD 1 seal failure

resulting in HYD 1 system failure.
