Aircraft will glide maximum distance at best lift/drag speed. In this case it corresponds to 4° angle of attack.
The speed at which the aircraft glides the maximum distance from a given altitude. This speed corresponds to the one that gives the best L/D (lift/drag) ratio. An aircraft with a higher L/D ratio will glide farther than an aircraft with a lower L/D.

With tailwind, one should reduce the airspeed below best glide speed, which in turn reduces the sink rate.
I maintained best glide speed until entering the trees, then I deliberately stalled the airplane, coming to rest in a cradle of branches 10 feet agl (5).
The system wants to know the power-off glide ratio at best glide speed, clean, with the prop at the high RPM--highest drag setting; the ratio, clean, with the prop at the low RPM setting and the ratio with the gear and flaps down, prop at high RPM and the speed at the max allowed for full flaps--essentially how it glides at best plummet speed.
Perhaps we should cut right to the life-saving takeaway: If you're engine-out in a typical single and gliding into a headwind of 15 knots or more, pitching down to at least 10 knots over published best glide speed will probably extend your glide range.
BETTER BEST GUIDES--There's a best glide speed listed in your POH or AFM, but that's not necessarily the speed you want to use when it gets disturbingly quiet.
in January's issue is the best explanation I've seen of the difference between minimum sink speed (VMS) and best glide speed (VG).
During the experiment, we used the 60-knot best glide speed for both propeller stopped and windmilling conditions.
The pilot reported pitching for best glide speed but realized the airplane was too low to make it to the runway, so he decided to make a forced landing in an open field.
The beauty of a well-executed slip is that you can lose a few hundred feet to get to your desired altitude, then return to coordinated flight and immediately return to best glide speed.
