→Booking Training Slots
The columns (K21/Puchacz/Perkoz) show the aircraft type. If you're booking for the first time, this doesn't matter, and you can pick any aircraft. The rows show the time of day (AM / PM) and the instructors name. If you are new, its important you do not book the instructors prefixed with 'XC', as these offer a different type of training. Note that there is a link at the top of the page to view dates further ahead than the default view.
You can book a slot by clicking your
name on any of the ''Book'' hyperlinks which will show in open slots.
'''In Winter: ''' AM slots are from 08:45 to 12:30, PM slots are from 12:30 until flying stops. This is usually 5pm or sunset (whichever is earlier).
