FLAP SYS. – FLAP SYSTEM
A23
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 FUNC.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
an Elevator deflection for each flap position. This is called
Elevator Compensation. 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 compensation 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 FUNC.LIST to
obtain the Flap System display if the aircraft has flaps or
Flaperons that are also going to be used as flaps.
