If you find yourself in an alpine emergency situation or a group member is injured, you make an emergency call. The control center decides whether to send a helicopter or another rescue vehicle (snowmobile, rescue car, terrestrial rescue). A realistic description of the emergency situation is a prerequisite for this.
The exact location of the accident is particularly important for the call taker at the control center, but if a helicopter is required, this information is even more relevant. “From the air”, the terrain and the situation are different and it must be possible to specify the location as precisely as possible. In this context, the various national and regional emergency call apps that transmit the exact position data (coordinates and altitude) to the control center after activating the emergency call button are highly recommended. If you do not have such an app, you should be able to describe your location as well as possible (e.g.: ski resort XX, ski route YY, just below the ZZ hut, etc.) and specify the altitude. There are already apps installed on every smartphone (compass, etc.) that display the altitude – and usually also the location via coordinates – as well as numerous others that provide the same information (e.g. tour planning, map, avalanche apps, etc.).
The call taker also gives the caller instructions on what to do next. Above all, the control center will instruct him/her to remain reachable by telephone! This is the only way the helicopter crew or the control center can inform the caller in the event of uncertainties, e.g. regarding the accident location or changes to plans (arrival takes longer, a flight is not possible due to the weather situation, etc.).
This means that the calling person’s cell phone must remain switched on, they must also hear when a call comes in and the line must be kept free for such a callback. However, because the cell phone battery quickly loses power in winter due to low temperatures and the ringing can easily be overheard when wearing a helmet and in windy conditions, it is advisable to use the cell phone with a small headset (or to connect it to the headphones/microphone of the helmet). This way, the phone can be kept “warm” and protected in your jacket pocket, you won’t miss a call and your hands will be free to follow the call taker’s first aid instructions.
