Practial IFR: Have a Speed-to-Fly for Emergencies in IMC
One refinement that rarely gets taught is adjusting best glide speed (Vbg) for changes in weight and wind. In a glider, if you’re heading back to the airport with a headwind, you can’t just open the throttle to make up for lost groundspeed. Instead, you pitch down to speed up. A lot. In fact, you might add 20 knots to your best glide (L/Dmax) speed to counter a 20-knot headwind.
