SCANNING, Observation of the Airspace and Deployment of Flaps

It is a sign of good airmanship if you are able to take a quick look at the ASI before each movement of the flaps. You must then verify that the air speed remains within the permissible range.

The electrically driven flaps always take the same amount of time to move from one position to the next. It does not make sense to observe the movement of the needle on the dial during flap deployment.

SCANNING, Observation of the Airspace and Deployment of Flaps

The following procedure is recommended:

• Touch the flap control, visualy check its current position!

• Move the control to the next position, or press as long as necessary to reach the next position (eg 2 seconds).

• Visually check wether the flaps have reached the intended position.

If the procedure is carried out in this way, the observation of the airspace and the attitude of the plane need not be neglected!

PRESELECTION

If you know the behavior of the aircraft during a configuration change, you can improve your capabilities by the PRESELECTION technique. Here are two examples to illustrate this technique:

• Straight and level flight in the approach configuration requires engine power setting in order to maintain the required airspeed (reference RPM).

• During the descent, the power can already be preselected to this value. The final value will be adjusted during the stabilization phase of the straight and level flight with small adjustments.
