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.

At the wing root. This is a property of rectangular wings, but it's also common to find close to the wing root devices that make it so that the wing root stalls first.

For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.

Radiation fog forms on cloudless nights with only very light winds and high relative humidity when the cold ground cools the air above it to its dew point causing condensation (fog).

Usually occurs inland in valleys and low lying areas (as these areas tend to have more moisture) and usually occurs in a high pressure system.

A Fohn wind is a warm dry wind that blows down the lee side of a mountain.

Initially, the air temperature cools dry-adiabatically (3°C/1000 ft), until its dew point temperature is reached. Condensation occurs as the air is further forced up the mountain range, resulting in the air cooling saturated-adiabatically (generally considered in the mid-latitudes to be 1.8°C/1000 ft). Clouds and precipitation form. When the air mass reaches the top of the mountain range it has lost a significant amount of its water content and so has a much lower dew point temperature.

As the air then begins to descend down the lee slope of the mountain the compressed air is initially heated saturated-adiabatically, and in effect the direct reverse to the cooling effect on the windward side occurs. As the air continues leeward and downward from the mountain range, the air, now no longer saturated, is heated dry-adiabatically.

The resultant wind is dry and warm giving clear conditions at airfields on the lee side of the mountain range.

The Foehn Effect also may be associated with mountain wave activity.

Swept wings are:

Better for high speed flight as they have minimal camber and thickness reduce drag and delay Mcrit More stable in turbulence as they produce less lift and as a result they are less responsive to updraughts

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

Because of the distance which has to be covered to reach 41.000 feet which may not be convenient for a short flight.

On long flights it is more typical to fly at 41.000 feet when the aircraft weight and performance allows.
