Quick overview
Key figures for helicopter operation (detailed explanation can be found below):
- CAE-BS/STASS (short term air supply system) briefing mandatory for all passengers (an instruction can be given by the pilots on board for persons that are occasionally flying, but this is not the same as a training ashore and the operator assumes no liability for this on board training)
- HUET (helicopter underwater escape training) training strongly recommended for all frequent flyers
- 5 passengers maximum plus pilot
- helmet and immersion suit mandatory
- survival bags to be taken on every flight
- only 1 group out by helicopter in a distance 3-80nm (second helicopter allowed in a distance up to 3nm from Polarstern)
- shuttling teams (bringing one team out and taking another one in with one flight) is not allowed
- if only one helicopter is available due to technical reasons, the maximum allowed distance is 10nm from Polarstern
- the standby time on ground/ice without engines running has to be limited according to the outside local conditions
- operation below -30°C air temperature is limited, below -45°C prohibited

Helicopters are provided by the shipping company F. Laeisz and operated by Northern Helicopter in Emden, Germany.
The German aviation law for offshore flying is applied.
Supervisory authority is the Federal Aviation Office (LBA-Luftfahrtbundesamt) which implements the EU law of the European Aviation Safety Agency (EASA).
Helicopter operations onboard (daylight conditions)
A so called "STASS" or "CA-EBS" - briefing is required for all helicopter passengers.
CA-EBS = Compressed Air-Emergency Breathing System; STASS = Short Term Air Supply System
Without the briefing you are not allowed to use the helicopter. An instruction can be given by the pilots on board for persons that are occasionally flying, but this is not the same as a training ashore and the heli operator assumes no liability for this on board training. Halfday STASS trainings can be completed at one of the training centres mentioned below. Frequent flyer are strongly recommended to take part in a full "Helicopter Underwater Escape Training" (HUET) before the expedition.
Commercial companies like e.g. "Windguard" or "RelyOnNutec" offer courses.
Please register yourself for any suitable training course on your own costs. (AWI-Logistics does not organize or pay for courses)
You will get training and info on how to behave and how to use the emergency breathing device in case of an emergency landing.
The equipment is weight-optimized and planned for an absence of max. 17h. (max. rescue time)
There is no food in the equipment and the fuel bottle for the cooker must be filled on board !
To take part in a training course mentioned above you will have to prove your medical fitness by presenting a medical certificate for offshore duties. Information on how to receive such a certificate can be found here: Medical Examination
Helmets must be worn in the helicopter for safety reasons at all times. Immersion suites with a self-inflatable life vest are obligatory during flights. The equipment is available onboard.
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. (Pilot+Doc. + 6 persons of helicopter 1 ==> 8 persons in helicopter 2) 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 e.g. a weather deterioration, helicopter crash, break-up of ice floes or polar bear attack.
Only one group will be allowed in the field at the same time 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 chief scientist, 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 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 or other means is possible in an acceptable time.
It might be that the helicopter operator needs to obtain permissions for take-off and landing before the expedition through local air administrations. Therefore you should announce your flight plans to the chief scientist at an early stage.
