What is a trainer aircraft?

• A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews.
• Modern military aircraft are notoriously difficult to master for rookie pilots. Hence, they must first be trained on other, more basic aircraft.
• Trainer aircraft are far more forgiving than the aircraft military pilots will eventually fly — they fly slower, have less complex systems, and are designed to be resistant to and recoverable from stalls and spins, a common challenge for rookie pilots.
• They are also much cheaper, allowing air forces to buy them in bulk to train cadets.

Q1) What is a turboprop engine?

It is a variant of a jet engine that has been optimised to drive a propeller. Turboprop equipped aircraft are very efficient at lower flight speeds (less than mach 0.6), burning less fuel per seat-mile and requiring significantly less runway for takeoff and landing than a turbojet or turbofan powered aircraft of the same size.
