Aero Ae.50

The Aero Ae.50, an experimental military reconnaissance aircraft built in Czechoslovakia, was designed for artillery spotting.

It featured a unique high wing monoplane design with a fuselage that abruptly ended behind the crew cabin, resulting in the tailplane being attached to a single boom connected to the wing.

The tailwheel was positioned at the back of the fuselage to optimise the observer’s visual range.

Additionally, it had a towing point that allowed it to be towed by another aircraft with a longer range, enabling transportation to combat areas beyond its operational range without refuelling stops.

Despite its maiden flight on April 14, 1949, and evaluation for a defence ministry contract against the Praga E-55, the Ae.50 faced challenges such as directional stability and issues with the leading-edge slots.

Efforts to address these problems were unsuccessful, and the aircraft’s excessive weight ultimately led Aero to halt its development.
