Open data

At E-Flight, we believe in transparency. Electric flying is new, innovative, and sometimes still unfamiliar territory. That's why we openly share our operational data and performance. This shows what is already possible with sustainable aviation and the steps we're taking together towards a clean future.

Pipistrel Velis Electro noise levels

Our electric fleet is whisper-quiet compared with traditional aircraft. Measurements show:

  • 47,8 dBA at cruise speed (24 kW, 80 kts, 2050 RPM) at 1.500 ft

  • 41,2 dBA at cruise speed (24 kW, 80 kts, 2050 RPM) at 3.000 ft

For comparison: that's quieter than an average conversation between two people!

Operational figures

  • More than 13,000 electric landings

  • Over 4,200 hours of electric flight time. Equivalent to 90,000 kWh charged

  • The Pipistrel Velis Electro flies for an average of 45 minutes per session

  • The Velis Electro has 2 batteries, which together weigh 140 kg. The aircraft's empty weight is 425 kg, leaving room for 2 people weighing a maximum of 175 kg.

  • Merlijn van Vliet (E-Flight Academy) also expects batteries to improve in the future. The Pipistrel's batteries have an energy density of 160 Wh/kg. This means each kilogram of battery weight can store and deliver 160 watt-hours (Wh) of energy. For comparison, the average electric car has an energy density of 250 Wh/kg.

    ‘But the batteries in our aircraft date from 2020, so they're actually already outdated,’ says Van Vliet. ‘Technically, batteries of 450 Wh/kg are already possible.’ We only see figures like that in the laboratory for now, adds Jolanda Stevens of KLM. ‘Not at scale yet. Once that happens, it will get interesting.’ (Source = MT/Sprout, 08-09-2025)

  • Charging takes 20–30 minutes using our fixed airside charging stations, depending on the state of charge and conditions

  • Charging with the mobile Pipistrel charger takes 1 hour at 32A (longer at 16A)

Charging infrastructure & energy supply

  • 4 fixed airside charging stations suitable for aircraft and electric cars

  • 504 solar panels on the roof of our high-end hangar, E-Deck

  • 500 kWh of battery storage for surplus energy

  • Our own solar energy powers the entire fleet and the car chargers; surplus energy is fed back into the grid

Our impact in numbers 🌍✈️

By flying more than 4200 hours electrically we have:

  • 69.000 liters of fuel saved

  • 160.150 kg of CO₂ (more than 160,1 tonnes) less emitted

That's equivalent to the annual CO₂ emissions of around 105 petrol cars!

Our fleet

  • 5 Pipistrel Velis Electros (fully electric)

  • 2 fuel-powered aircraft (Bristell B23 and Pipistrel Explorer)

E-Flight in numbers

  • 15–20% of all flight movements at Teuge Airport are fully electric

  • 50% of all electric flight movements worldwide

Curious about Pipistrel Velis Electro activity at Teuge and other airfields? You can follow recorded flight movements by electric aircraft via Electric Aircraft Airports. Please note: this overview counts flights since September 2024—we have actually completed many more electric flights.

  • Expansion to Lelystad Airport in the short term

  • Winter operations in Spain or Portugal (TBD)

  • Caribbean expansion (Aruba & Bonaire) planned for 2026–2027

Training & partnerships

At E-Flight, we train a diverse group of students:

  • Around 60 PPL students

  • Advanced training programs such as IR and CPL

  • Additional training: Night Rating, Advanced Courses

We also work with major partners such as the Ministry of Defence, Corendon, LVNL and NLR.
