Stall speed is defined as the minimum steady flight speed at which the airplane is controllable.

Profile drag, also known as pressure drag or form drag, is the drag caused by the separation of the boundary layer from a surface and the wake created by that separation.

It is primarily dependent upon the shape of the object and increases directly with speed as the faster an aircraft moves the more air molecules collide with it.

This provides pitch manoeuvrability.

Longitudinal balancing by the trim system.

The speed is too low for an indication.

Wing loading is the loaded weight of the aircraft divided by the area of the wing.

The faster an aircraft flies, the more lift is produced by each unit area of the wing. Correspondingly, the landing and take-off speeds will be higher and the high wing loading also decreases maneuverability.

The assessor was trying to get to the approach where you need flaps and slats to increase S (lower wingload) in order to be able to fly a lower speed.

Vmu is the minimum unstick speed.

It is the calibrated airspeed at and above which the airplane can safely lift off the ground and continue the takeoff. Lift-off is not possible prior to reaching this speed.

Vmu is not an operational speed and is established in flight testing only.

A Mach trimmer is a system that artificially corrects for Mach tuck.

This speed is defined to be equal to the greater of stall speed (Vso) multiplied by 1.3, or stall speed (Vs1g) multiplied by 1.23.

The landing configuration that is to be taken into consideration can be defined by either the operator or by the aeroplane manufacturer but is most commonly assigned by the manufacturer.
