Center of pressure moves forward when approaching a stall.

The Dry Operating Mass (DOM) is the Basic Empty Mass and the Variable Load, also called the Aircraft Prepared for Service (APS) weight.

A line across the surface of the earth that cuts all meridians at the same angle. i.e. a track of constant direction.

A straight line on a Mercator chart.

To protect the engine from blowing up as it is easy to open the throttles to far during take off at sea level.

Occluded fronts are formed during the process of cyclogenesis when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's surface.

Occluded fronts usually form around mature low pressure areas.

An adymensional number relating the lift with the dynamic pressure of the incoming flow. It is dependent on the form of the object and the angle of attack.

It's the wing area divided by the wing span.

Swept back wings

1st segment starts at screen height and finishes at gear retracted.

2nd segment starts when the gear is retracted and finishes when acceleration alt is reached (min. 400ft max 1000ft) speed V2.

3rd segment starts at acceleration alt, minimum 400ft, and finishes when the flaps are retracted.

4th segment starts when the flaps are retracted, MCT is set and finishes at the 1500ft.

TAS will increase.
