We do this thing with every horse, every ride. We call it anti-flight checks. We do it at a standstill because you don’t want to discover you can’t stop your horse once you are already moving.
The name comes from correlation to a pilot’s pre-flight check, but we prefer not to go flying, so they are anti flight checks!
We decided to have one of our students explain them for you, instead of having me drone on about it!
