Had a great flight this morning. The air was smooth as glass. Today I calibrated my Lift Reserve Indicator. It’s not completely accurate yet but it’s close enough. The LRI can be thought of as either an angle of attack indicator or a an airspeed indicator that is extremely accurate at low speeds. The instrument is connected to a probe that has two inputs which ram air enters at two different angles. The LRI instrument compares the two pressures on the two ports and moves a needle accordingly. You calibrate the probe by changing the angle at which it protrudes below the wing, thus altering the angle at which the air hits the two ports.
I also took the opportunity to do some pre-Fourth of July sight seeing. Here are a few shots of Lake Don Pedro from this morning’s flight.
Only 6 more hours and I’m set to carry passengers, and leave my test area! Oshkosh here I come!
