For your safety, no flying is allowed on the day of arrival in Namibia. Due to the large temperature differences, it is important that you acclimatise before taking off.
Regulation according to SSN (Soaring Society of Namibia): If the time difference between Namibia and your point of arrival is less than four hours, you need a rest period of 24 hours. If the time difference is five hours or more, you may not fly within the first 48 hours.
The evening before your first flying day, you will take over the aircraft and familiarise yourself with it. The next day, after the briefing, you take off on your first flight.
