VMCA is the Middle Cerebral Artery Flow Velocity (cardiology/pulmonary medicine) And,VMCG is the minimum control speed on the ground (aviation)
Can vary for different aircraft, but it depends on the number of seats
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.
Not--the terrain and type of aircraft Not--all of the terrain, type of aircraft, and environmental conditions
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
It's not so much "needed" as it is a physical consequence. The empty weight is the weight of the aircraft itself - without fuel, crew, passengers, cargo or weapons.

Premiums vary depending on your aircraft. Consult with your speciality insurance agent for a quote.
The Gross Weight (Empty weight) of an X-15 is 14,600 lb.
600 kg for aircraft operated from land, 650 kg for seaplanes.
It is important because it is essential for for climbing of aircraft. There is a limit for thrust to weight ratio. When an airplane exceeds it, it cannot climb effeciently.
