In the world of Van’s RV Homebuilt Aircraft there is an event known as “joining the 200 knot club”. It’s for aircraft that have surpassed 200kts (230mph) groundspeed in level cruise flight. By far the majority of Van’s RVs have a top speed in level cruise around 175 kts or 200 mph. So a pretty good tailwind is required.
Thursday 4/7 on a flight retrieving N50KB from Michigan to Florida we (I and the plane) joined the club. Click on the photos to see the detail. What a ride!
There was a 72 kt tailwind component at 14,500 ft msl. That plus the 143 kt full throttle (59% power) true airspeed pushed and pulled us at 215 kts over the ground.
9.9 gallons per hour. 24.9 miles per gallon. Hooah!!!
