Helicopter BK117 - Polarstern (Photo Heliservice)


Helicopters are provided and operated by Heliservice International from Emden.

The German aviation law for offshore flying is applied. Supervisory authority is the Federal Aviation Office which implements the EU law of the European Aviation Safety Agency
(EASA).



Helicopter operations onboard

Helicopter operations are legalized by the Standard Operation Procedures - SOP" of the helicopter operator. The documents authorized by the Federal Aviation Office can be found onboard with the flight officer. 

Helmets have to be worn in the helicopter for safety reasons at all times. Immersion suites with a self-infloatable life vest are obligatory during flights over open water. The equipment is present onboard.

A survival package is taken along for each person and a tent for 4 persons. The equipment is present onboard.
The equipment is weight-optimized and only planned for absences of max. 12h. There is no food in the equipment!

One helicopter stays onboard or in the close vincinity of the ship ( < 3 nm) for safety reasons, while the other is in use.

The used helicopter is flown by a pilot, the other pilot occupies the "Tower" onboard.

Theoretically, there are 7 places available for passengers. However, only 5 passengers can come along plus the pilot because all 6 persons must be rescued in case of emergency. Rescue of all persons on the ice has to be possible with only one helicopter operation so that no one stays behind in case of a weather deterioration, helicopter crash, break-up of ice floats or polar bear attack.

Only one group will be operational due to the above mentioned reasons.

Stand-by of a helicopter on site is 45 minutes. If longer stays are required the helicopter goes back to the ship and collects the group later.  In this case the group must be equipped with GPS and Iridium telephone. There are 2 Iridium telephones available onboard from the communication electronics engineer.

There will be a meeting of cruise leader, captain, pilot and meteorologist before every flight for discussing the flight plan. The decision if flying is possible or not has to be unanimous. The pilot always has the final word . The flight programme must be documented in writing.

The pilot can always abort the operation. This decision is mandatory and must be followed immediately.

If only one helicopter is operational for technical reasons, the other helicopter may operate within 10 NM of the ship only. Thus, in case of emergency rescue measures can be undertaken from the ship in due time.

It must always be expected that the group of 6 persons can not be collected in time because of weather conditions. The position of the working area has to be chosen thus that rescue by the ship is possible.

It might be that the helicopter operator needs to obtain permissions for take-off and landing before the expedition. Therefore you should announce your flight plans to the cruise leader at an early stage.


We strongly recommend to take part in a full "Helicopter Underwater Escape Training" (HUET) before the expedition.

A so called "STASS" or "CA-EBS" - Training is required for all helicopter passengers before the expedition.
You will get training and info on how to behave and how to use the emergency breathing device in case of an emergency landing.
Please contact "Schiffscoord@awi.de" for further information.
CA-EBS = Compressed Air-Emergency Breathing System; STASS = Short Term Air Supply System

Without the training you are not allowed to use the helicopter.
