To be the most efficient, aircraft descend at Vmd. Vmd increases with Weight, and therefore the rate of descent increases as well with weight.

A turbo charger is externally driven by exhaust back pressure turning a turbine which in turn drives a compressor in the induction manifold to increase the air pressure (constant volume, higher pressure) and is controlled by waste gate.

A supercharger is internally driven by the propellor shaft to compress mixture and is controlled by RPM.

Average range over land 20 - 25 miles.

Range for an NDB can be calculated with:

2√power output in Watts = Range (Land) 3√ power output in Watts = Range (Water)

Alternate air is....

A line of shortest distance between two points on a sphere.

Minimum Safe Altitude.

The speed is too low for an indication.

-35°C

Transmitting uses more power.

A variable pitch propeller provides an optimum angle of attack for the propeller blades for a longer range which reduces fuel usage, fixed pitch propellers only have a certain rpm.
