Our Vision

Zero accidents due to missing performance calculations

According to the latest aviation accident report, human error causes 80% of all accidents. What troubles pilots most: "landings, takeoffs and climbs, low-altitude maneuvering, and fuel mismanagement."

Iduna FLY is calculating all relevant numbers for you. Required runway distance, climb rate, fuel usage, mass & balance, emergency speeds and much more. Knowing the official limits of the airplane, is as easy as it gets.

We dream of general aviation where:

  • the runway is always long enough for takeoff and landing
  • there is always enough space between the ground and the airplane during climb
  • the pilot always has enough fuel on board for trip, alternate, extra and contingency
  • all pilots are aware of their airplanes limits at the current weather conditions

To make that dream come true, we created Iduna FLY. A complete preparation takes about 39 seconds. Less than a minute to know your airplanes limits for today's temperature, pressure, and load. Thinking if you should do a complete preparation takes longer than doing it.
