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.

Decision altitude (precision), the altitude at which a decision must be made during an ILS, MLS, or PAR instrument approach to either continue the approach or to execute a missed approach.

No, there is no P-factor (asymmetric blade effect) as on a propeller-driven aircraft.

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 turbofan is a type of jet engine, similar to a turbojet.

It essentially consists of a ducted fan with a smaller diameter turbojet engine mounted behind it that powers the fan.

Part of the airstream from the ducted fan passes through the turbojet where it is burnt to power the fan, but the majority of the flow bypasses it, and produces most of the thrust. They are mainly used commercially because they are highly efficient and relatively quiet in operation.

Lift is the component of the total aerodynamic force perpendicular to the relative airflow.

Lift is generated when a streamlined body, such as an aerofoil, is placed in a flow of air.

Fuel injection provides:

• Fuel free from vaporization ice

• Better economy through metered delivery

• More responsive and efficient engine

• Less maintenance

Swept back wings

Transmitting uses more power.

Downward inclination of a wing from the root to the tip.
