Hows glide ratio calculated
The sum of forward speed divided by sink speed
What’s glide ratio
The ratio of distance forward to distance downwards
What three variables affect The values of specific range versus speed
Aircraft gross weight
Altitude
The external aerodynamic configuration of the aircraft
What’s the load factor
the resultant force, or lift in a turn, divided by the weight. It is also called the ‘g‑Load’.
