ENGINE ANTI-ICE PROTECTION SYSTEM
To prevent ice buildup on the engine nacelle leading edges, hot engine bleed air is used. It is manually controlled
by the PROBE/WINDOW HEAT pb. When engine anti-ice is selected engine idle speed will increase and continuous
ignition is automatically selected.
RAIN REMOVAL
Both front windshields have individual windshield wipers
controlled by three position switches on the overhead
panel. Activating them on a dry windshield might cause
damage to the windshield. Using the wipers at airspeed
over 240 knots might result is not advised.
LANDING GEAR AND BRAKES
GENERAL
The landing gear consists of a steerable nose gear with two wheels and two main landing gears with two wheels.
The nose gear retracts forward and does not have any brakes. The main gear retracts inboard and is equipped
with carbon disk brakes. An auto brake system and anti-skid systems are available to assist the crew in halting the
aircraft under less favorable conditions. An interlock system prevents gear retraction when the aircraft is on the
ground. In case of total hydraulic failure the gear can be extended with a manual crank handle. On retraction the
main gear is automatically braked using the normal brakes. The nose gear is braked with a friction band on
retraction.
