SAFETY
Safety switch (landing gear retraction) :
A safety switch installed on each main landing gear prevents, by detecting
shock strut compression, landing gear accidental retraction when airplane is
on ground.
Landing gear horn :
Landing gear horn is controlled by power lever and / or flaps. It sounds
(continuous high–pitched sound) when :
– power lever is on IDLE position and landing gear is not down–locked,
– flaps are beyond ”TO” position (Takeoff) and landing gear is not
down–locked.
NOTE :
If one of above conditions exists and airplane is in stall configuration, the
audio–warning signal becomes alternated (high–pitched sound /
low–pitched sound).
Emergency landing gear extension control :
Emergency landing gear extension control consists of a hand pump and a
by–pass selector.
This control is accessible by removing the floor panel located aft of the
pedestal.
After bypass selector closing, hand pump operation sends hydraulic fluid
directly into landing gear actuators ; landing gear full extension and locking
requires about 65 cycles.
