Parabolic flight

The offered parabolic flight campaign consists of three flights on three different days. During each flight 31 parabolic manoeuvres are flown. The first parabola is considered a “warm up” parabola to give everybody on board the possibility to get used to the altered gravity conditions.

The manoeuvre is depicted in this image. Starting at a steady horizontal flight, the pilot increases thrust and gradually pulls up and starts climbing to an angle of approximately 50°. During this pull-up phase of approximately 20 seconds the acceleration in z-axis of the plane is around 1.8g. After this the engine thrust is strongly reduced to only compensate for air-drag, the aircraft is then in free-fall state for approximately 20 seconds in which weightlessness occurs. The trajectory of this free-fall follows a parabola, from which the manoeuvre has its name.

At the end of the manoeuvre, the aircraft pulls out of the parabolic arc to return to horizontal flight, resulting in another 20 seconds of 1.8g. Each of these 1 minute cycles (20s at 1.8g – 20s weightlessness – 20s at 1.8g) is followed by a 2 minute break or an 8 minute break after every 5th parabola.

Throughout the flight, all personnel are kept informed of the flight status such as indication of how many seconds to the next parabola, number of minutes for a rest period so on and so forth.
