N291DR 2.0 Airball data gathering flight

Another Airball flight. This time, I was doing GPS assisted IAS calibrations.

I took off from KRHV and took a right turnout departure. Then I realized one of the pressure sensors in the probe was plumbed backwards. Yikes. I puttered for a while then decided to come back.

I realized that the easiest thing to do was to simply change the firmware to negate the reading, and call it a day. I did that and went up again. Another right turnout departure.

I spent a long time around 5,500' MSL over the private airfield in a valley East of KRHV, doing 3-legged passes at different airspeeds, including ones where I put in about 10 degrees of yaw in one direction or the other, tried to hold a constant heading, airspeed, and altitude, and recorded the GPS readings.

Back to KRHV for my second landing of the day. It was a rather grueling 2 hours, but fun! Hope the data looks good!

N291DR 1.1 Airball data gathering flight

Quick flight over the hills East of San Jose to try out a new probe placement, on a boom on the wingtip. 1 landing at KRHV. I tried a short landing with power and full flaps, and I made my exit on taxiway B easily, but I still floated a lot,. I was doing around 50 kias over the fence, but should have slowed to around 40 kias on short final. Next time.
