Electra has introduced its advanced eSTOL (electric Short Takeoff and Landing) aircraft into the market. The innovative features of this hybrid electric aircraft have received positive attention from the aviation sector— along with substantial pre-sales amounting to more than $8 billion. By taking advantage of both electric and conventional propulsion systems, the aircraft attains a unique position that is ordered over $8 billion worth in orders. This seems to be based on an assurance of confidence: from what it promises — quiet, long-range, low-emission flights; yet it uses minimum runway space.
Electra’s method is less science fiction and more of an everyday take on innovation despite not being typical. The plane includes eight small diameter five-bladed propellers placed along the wing powered by electric motors that are quiet in operation. The motors receive power from a large lithium battery pack which allows for completely electric takeoff and landing sequences; noise levels produced by the aircraft are very low— only 75 decibels at 300 feet (91 meters), thus making Electra an urban-friendly choice for residents living near airports.
The hybrid system includes a range-extending generator, allowing the aircraft to achieve longer flight distances that purely electric aircraft currently cannot match. Electra’s aircraft promises cruise speeds of around 200 mph (322 km/h) and a range of approximately 500 miles (805 km), with a 45-minute reserve. This efficient system is expected to cut fuel consumption by up to 40% on short flights, although the savings may decrease on longer journeys where the generator runs more frequently.
One of the most remarkable aspects of Electra’s eSTOL aircraft is its ability to take off and land on very short runways. The aircraft’s design creates a blown-lift scenario, enabling it to operate on airstrips as small as 300 x 100 feet (91 x 30 meters). In its first STOL test flight at Manassas Regional Airport in Virginia, the EL-2 Goldfinch demonstrator aircraft took off in less than 170 feet (52 meters) and landed in under 114 feet (35 meters), achieving an altitude of 6,500 feet (1,980 meters) and flying as slowly as 25 knots (29 mph/46 km/h) during takeoff and landing.
This achievement demonstrates the aircraft’s capability to operate from extremely short spaces, fulfilling its design promises. Electra continues to develop its technologies, including the ‘thrust-by-wire’ flight control system, aiming to further enhance its STOL performance. The company seeks FAA commercial certification under Part 23 regulations and expects its production aircraft to enter commercial service by 2028.
