Engineering and aerodynamics

The critical angle of attack is the central connection. The associated speed depends on mass, load and configuration.

Above all, the transverse rudder produces a rolling movement. For a clean curve, the coupled effects are taken into account.

The mass and centre of gravity shall be checked separately. Both must be within the allowed range.

Fuel compatibility and operating limits are system-specific. General similarity is not enough.

GNSS describes the movement over ground. The airspeed meter uses air pressure variables and measures something else.

Starting power depends on the conditions. The data and corrections suitable for the model as well as a sufficient margin are necessary.
