Average range over land 20 - 25 miles.

Range for an NDB can be calculated with:

2√power output in Watts = Range (Land) 3√ power output in Watts = Range (Water)

There are 2 types of leading edge devices:

-Slats. Slats are movable surfaces on the leading edge of the wing which when deployed, allow the wing to operate at a higher angle of attack, by delaying separation in the wing upper surface.

-Leading edge flaps (Krueger). Leading edge flaps are hinged on the leading edge of the wing and extend forward and down when deployed. they provide similar benefits as trailing edge flaps, by increasing wing surface area and camber.

Mcrit is the aircraft’s Mach speed at which the airflow over a wing becomes sonic.

Center of pressure moves forward when approaching a stall.

To be within aircraft design limitations with regards to:

Take-off and landing performance

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.

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.

Hydraulic system A and hydraulic system B.

No, tropopause at the pole is lower (30.000ft) than at the equator (56.000ft)

A stall strip, usually located close to the wing root, causes the airflow to separate at a lower angle of attack and ensures that the wing root stalls before the wing tips.
