If you only need a check flight you do not need to book instruction. However if after the check flight you are not approved for solo their may not be capacity for you to fly with an instructor. We recommend that the first few times you plan to fly solo you should book a slot with an instructor. You should also book a slot if you have not flow for a while.
After Going Solo
Lots - Learning to glide is fun, but the real fun starts after you go solo. There are a wide range of options from aerobatics to cross-country flying and competitions. On a nice day glider pilots often do 300 km flights across the country, while the best pilots can fly over 1000 km, only using the air currents to stay up.
