Measured best glide speed and sink rate. Conditions: - Full fuel - No pass or baggage Procedure Climb to 7000 MSL. Set direct to KCRE, approx perpendicular to wind. Mix, Prop, Ram in, cut power, set IAS to desired and take picture every 30 sec to 3000 ft MSL. Climb and repeat at new airspeed. Continue on reciprocal course direct KSUT. Results Best glide speed (Vg) was 80 KIAS. Sink rate about 900 ft/min. Glide ratio 1.68 miles/1000 ft (8.8 ft//ft).
