User Manual

FLAP SYS. – FLAP SYSTEM
The XP9303 features a three-position Flap System with Elevator compensation, programmable
Delay, and an Auto Land feature. Its purpose is to allow the flaps to be deployed in two different
positions in addition to the normal or fully retracted position. The Flap System is available in the
FUNCTION List only if SYS. is selected on the OUT line under FLAP in the Devic. SEL
function within the SYSTEM Menu.
Because deploying flaps generally causes a change in pitch (elevator trim), the Flap System
provides for setting elevator compensation/deflection for each flap position. There is also a
programmable delay in .1 second increments up to 2 seconds maximum. The delay determines
how long it takes for the flaps and elevator to reach their positions. The XP9303 insures that the
flaps and elevator reach their positions at the same time resulting in smooth flap deployment and
retraction.
The Auto Land feature, if implemented, automatically retracts the flaps and elevator trim when
the throttle is raised above a specified throttle position. This can be useful during a missed
landing approach when a go-around is required.
The Flap System allows the flaps to be deployed using the Flap Switch, Flight Mode switch or a
combination of both.
Highlight and select FLAP SYS. in the FUNCTION List to obtain the Flap System display if the
aircraft has Flaps or Flaperons that are also going to be used as Flaps.
