Ok, that was groundspeed on the return flight yesterday returning from Mojave Airport/Spaceport back to San Diego at 11,500 feet. No record or anything, just a “personal best” for me and my Tiger. One of those many little things that make flying so much fun.
And I guess the strong tailwinds get most of the credit since I normally max out at 135 TAS. But hey, it still was fun watching the groundspeed spool up on the GPS, especially after slogging up to Mojave earlier in the day into the teeth of stong headwinds.
