In a high bypass design, the vast majority of the thrust is derived from the ducted fan, rather than from combustion gases expanding in a nozzle.

A high bypass ratio provides a lower thrust specific fuel consumption (grams/sec fuel per unit of thrust in kN using SI units), especially at zero velocity (at takeoff) and at the cruise speed of most commercial jet aircraft.

An anti-servo tab works in the opposite way to a servo tab.

It deploys in the same direction as the control surface, making the movement of the control surface more difficult and requires more force applied to the controls by the pilot.

Yes, for safety you will need a V2 speed.

-35°C

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.

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.

1kg = 2.2lbs

Yes, VMCG has to be equal to or less than V1 to ensure the aircraft could maintain runway heading having suffered an engine failure at or above V1 when the aircraft is committed to takeoff.
