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.

Reduced Vertical Separation Minima (RVSM) is the reduction, from 2,000 feet to 1,000 feet, of the standard vertical separation required between aircraft flying between flight level 290 (29,000 ft) and flight level 410 (41,000 ft).

The distance from the datum to the point at which the weight of a component acts.

The ratio between the wing span and the mean chord line.

A high aspect ratio is associated with good lift to drag ratio, i.e.: Gliders.

A low aspect ratio is usually associated with fast aircraft, i.e.: Fighter jets.

Fuel, speed and holding entry.

Jet streams are narrow bands of high-speed upper thermal winds at very high altitudes.

It’s an official document for the safety of the flight.

A copy of this document needs to remain on the ground.

anhedral is the downward inclinitation of the wing from the root to the tip.

The elevation at which the airplane departed from the runway.

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.
