Sitting back seat felt weird tonight
I'm not used to sitting back seat in a small plane. Tonight I did sit backseat, during someone else's instrument training (missed approaches, VOR/RNAV/GPS approaches, etc.) and found I learned an incredible amount about instrument flying that is sometimes hard to absorb when you are in the hot seat (as I usually am).
I took the opportunity in the back seat to watch the plane's altimeter over the PIC's shoulder as I correllated it with altitude readings I was taking with the SU-1 barometer modification on my Yaesu VX-5R handheld HT. At 4000 and 5000 feet altitudes in the San Francisco Bay area, over 2 hours of flying with reported surface barometric pressures of between 29.94 and 29.98 inches of mercury, without calibration, I was getting agreement ranging from 0 to 200 feet. It'll be interesting to see how much better the agreement is after I RTFM and do a pre-flight calibration.
