Airspace, even though less complicated than in England, can be tricky there as well. A week before my trip, CFI of another gliding club has intruded the Aberdeen airspace, infringement repeated an only week later by another club’s chairman - an honest mistake when flying downwind in 60kt upper winds. My piece of advice? Familiarisation with a moving map in a gliding computer is a must-be on your to-do list. Upper wave boxes used to fly without a transponder above FL100 can give one a headache as it is easy to unwillingly fly out of them right into controlled airspace (imagine: ground speeds can be well in excess of 150 kt.)

At this point I would like to thank Cambridge University Gliding Club which allowed me to take the club’s ASW19B – “CU” to Aboyne and Stephen Gibson from CGC who very kindly lend me his hi-performance oxygen system. Without them, I would have never spent as many as 37 hours in the air. Out of those hours, two flights are particularly notable and possibly of interest to the reader. The first one is my diamond height gain which happened on the 09/10/18. The second one is 268 km undeclared cross country flight in wave done on 10/10/18.

The evening before, the RASP wave forecast for Scotland seemed more than optimistic, with strongish south-westerly winds. I’ve decided to attempt an early start for the sake of an easy take off and plenty of time for looking for a good wave spot (and who can say ‘no’ to Scottish sunrise in the middle of autumn).

Thanks to Levi – very keen and helpful Hungarian tug pilot – I was able to take off with first sun rays shining onto the runway surface. As usual, he dropped me in the perfect wave entry location (keeping tug pilots well-oiled with a beer in the evenings is probably the best investment one could do while in Aboyne). The only thing left for me was to align with the best lift, fly back and forth along the wave clouds and cherish my eyes with a splendid sunrise over them (ha! the early bird does get a worm).

I found wave clouds and patterns harder to understand then thermals. With high wind speeds, places with huge sink and few outlanding options - the margin for error in the wave cross country flying is much smaller than in the thermal cross country, despite much higher altitudes at which one flies. I eventually finished an undeclared task of 268 km - being quite pleased of such an achievement. Understanding and harnessing this still under-reasearched energy allows for flights as long as two 750 km flights done from Aboyne on that day. If it weren’t for the wave cross country flying, I have no idea what Jean-Marie Clément had in mind when he wrote the words quoted at the beginning of this article.

Aboyne is a great place for trying wave flying for the first time, as well as getting diamonds or doing cross country flights one can talk about over a pint forever. Favourable weather, picturesque scenery, and friendly club make it a place worth paying a visit. An opinion shared by a group of German pilots, who have been travelling there every autumn for last few years, with their own gliders all the way from Germany.
