Flaps And Slats
The flaps and slats are controlled from a single flap lever on the right of the pedestal area. The flaps have 5 settings, Up, 1, 2, 3 and Full.
The flap and slat system have various safe guards to relieve the system for excessive speeds. To prevent retraction in alpha floor states. Etc.
The status of the flaps is shown at the bottom of the EWD at all times.
Flap Indications
Normal Indication for flap set for takeoff.
Flaps moving to setting 3. The setting mark shown in blue. However, the F is shown in amber for a flap failure. The flaps use Green and yellow hydraulics. Failure of these or the slat system produces an amber F
Slats use Green and Blue hydraulics. Failure of these or the slat system produces an amber S
The commanded flap setting is shown in blue whilst the flaps/slats transition.
The commanded flap setting is shown in green when the flaps/slats are in position
The flaps have an automatic load relieve for IAS speeds shown below.
