Minimum Safe Altitude.

The glide range is not affected by the weight. Howver Vmd is. The heavier the aircraft, the higher the Vmd.

A free turbine is a turbine that is not directly connected to the compressor. This allows the compressor to rotate at a different speed than the turbine. Since the turbine speed is coupled with the propeller, this allows for the propeller to be maintained at a constant ideal speed.

Another advantage is that free turbine engines can be designed to be more compact than their single shaft counterparts

The weight of an aircraft is applied at the CG. The lift at the CP. The relative position between these 2 points determines the stability of the aircraft. For an Aircraft with a tail surface, a CG in front of the CP constitutes a stable system, while a CG behind the CP an unstable system.

Drag is the component of the total aerodynamic force parallel to the relative airflow.

Drag is generated by any body placed in a flow and it's composed of friction, form, and pressure drag.

A METAR is an observation of the actual weather given by a meteorological observer at that aerodrome.

A swept wing makes the velocity vector normal to the leading edge a shorter distance than the chordwise resultant.

When rolling the aircraft the up-going wing will experience more drag than the down-going wing. This will result in a yawing moment that directly opposes the desired direction of turn. (i.e.: rolling left will cause a right yaw.)
