The speed is too low for an indication.

Angle of attack is the angle between the chord of the aerofoil and the relative airflow.

Angle of incidence is the angle between the chord and the aircrafts longitudinal datum.

Mach number describes the speed of sound, which changes with the density of the medium it is travelling through.

When you reach the speed of sound, the compressibility effect creates a supersonic flow along the wing if you exceed a certain mach number.

This causes airflow separation and flutter.

It is therefore much safer and much easier to use a Mach number to express a limit at which compressibility effects start to tear the aircraft apart, as it is a constant value at all altitudes.

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)

Yes, for safety you will need a V2 speed.

Due to the structural damage that may occur in thunderstorms, due to hail, severe turbulence and severe windshear.

Besides that, lightning strikes may cause damage to electrical systems and severe icing may occur.

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 are easier to produce and maintain, but reach maximum efficient at only one specific airspeed.

Jeppesen charts and plates are simplified and uniform.

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.
