2023 Elektra Solar Trainer

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 & 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 & 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 & can fly a mission completely autonomously including take-off & landing. The flight mission can be defined by means of a special software before the flight & changed or adapted during the flight from the cockpit or from the ground control station.

Digital Aircraft Platform (DAP)

DAP is the basis for all control & monitoring elements of the aircraft. DAP performs real-time monitoring of all aircraft parameters, provides intelligent assistance to the pilot & activates protection algorithms automatically in critical situations. DAP simplifies aircraft operation & maintenance. The life of each essential part (like batteries, motor, propeller, structure) is monitored in real-time, analysed & documented continuously.
