Chase Thermal Trigger Points, Not Hope
One of the most useful lessons in cross-country soaring is surprisingly simple: when you get low, stop thinking like a pilot and start thinking like the landscape!
Every soaring pilot eventually faces the same uncomfortable moment. The thermals disappear, the variometer falls silent, and the ground begins to look much closer than expected. One could argue that this is exactly when discipline and observation matter most. Instead of blindly chasing clouds or following other gliders, a pilot should study the terrain below and search for places where warm air is likely to form and release.
The key idea is that thermals do not appear randomly. They are created by uneven heating of the Earth’s surface. Dry fields, rocky ground, villages, parking lots, and sunlit slopes warm quickly and can produce rising air. Wet forests, lakes, shaded fields, and damp grass usually do not. A successful pilot learns to read these differences almost instinctively.
I think of this process as if I were taking a “mental stroll” across the countryside. Imagine walking barefoot through the fields below. Which places would feel hottest? Which areas would trap warm air? That mental exercise often leads directly to a workable thermal.
Equally important are “trigger points.” Warm air may sit near the ground for quite some time before something finally releases it upward. A ridge, a tree line, a quarry, a road embankment, or even a small group of buildings can provide the push that starts a thermal climbing.
Many of us can share several stories of low saves made by flying toward tiny but promising features in the terrain rather than continuing straight ahead in desperation.
One memorable example involved a flight where I had descended to the low levels above the ground. Seeing almost no signs of lift, I diverted slightly towards a small group of trees surrounded by rocks over a generally barren landscape. As I passed over it, the glider and air came alive, one turn, two turns, away! Experiences like this have taught me to never ignore potential trigger points, no matter how insignificant they appear.
The lesson remains just as relevant today as it was when I was learning the craft of climbing away from low. Modern instruments, GPS systems, and glide computers are valuable tools, but they cannot replace careful observation and good judgment. Successful soaring still depends on understanding weather, terrain, sunlight, and wind.
In the end, we must remember that soaring is not only about flying a machine. It is about learning to see the invisible structure of the atmosphere - and trusting that knowledge & experience when it matters most.
Happy and calm scratching!
