Extremely low noise level
50 dB noise level (German LTF-UL 2020) - moderate rainfall noise. Operation in noise protected areas possible.
Outstanding flight time
Flight time 2.5 hours (with 5kWh battery capacity reserve).
Unlimited number of flight training cycles: 50 minutes flight, 35 minutes charging with 18kW power.
Operational costs
50 EUR/h, aircraft depreciation cost, electricity and battery, maintenance, insurance. The operation cost of a classic two-seat UL class aircraft is more than 100 EUR. The Elektra Trainer's saving cost for the whole life of the plane (about 10000 hours) is about 500.000 EUR, which is much more than the aircraft's double price.
Redundancy
Dual redundant propulsion system. Each of two subsystems is composed of motor, motor controller, battery. Dual redundant power supply for avionics and autopilot. In case of failure of motor, motor controller, battery or all of them in one subsystem, the aircraft is able to climb with at least 1.5 m/s.
In case of OPS, double redundant electronic flight instruments.
Optionally piloted system (OPS)
Elektra Trainer Solar OPS is equipped with autopilot system. The pilot can switch to the autopilot mode and can fly a mission completely autonomously including take-off and landing. The flight mission can be defined by means of a special software before the flight and changed or adapted during the flight from the cockpit or from the ground control station.
