Just had a very interesting flight on PE.
I was flying a simple TEC route from KSNA to KSAN and was just reaching MZB flying at 5000 ft. with no troubles that I could tell. Then ATC told me they show me at 4200 ft. I checked my altimeter and it showed 5000. The controller and I confirmed that the altimeter setting is 30.05, we are both on the same page, but he is showing me 800 ft. lower than I should be!!
I started a hard scan on my instruments.
I was in some mild wind turbulence so my vertical speed and my altimeter should be fluctuating a little, but there is no movement in either instrument!!
I looked over at my airspeed, and it was showing 150 kts IAS, but my ground speed on the GPS was showing around 124!!
Everything was going wonky!
By the time I turned off the A/P and started hand flying the aircraft, I was cleared for a visual approach for 27 at KSAN and Keith was on tower.
I told him my situation and asked him to tell me when I hit pattern height (1000ft.)and to give me airspeed.
I asked him for this a few times to make sure I was within my landing configuration ranges for speed and altitude.
Keith got me down safe and it was not even that bad of a landing!!
http://assets.pilotedge.net/recordings/ ... _18011.mp3 - My call to Tower starts at the 6:43 mark.
My airspeed was still pinned at 180 IAS, my altimeter was still showing 5000 and my vertical speed was frozen at zero when I was stopped on the ground.
After I thanked Keith and sat on the Tarmac for a few minutes cleaning my shorts, I went to aircraft operations and failures and set everything back to operational. All my instruments went
back to normal.
I shut down the sim for the night, thankful that I kept the rubber side down!! Enough flying for one night!
My thanks also goes out to the approach controller who told me of the initial altitude difference, which then cranked on my flying brain two fold!!
I am not sure if I handled this as correctly as I could have, but it got me down in one piece, so I guess that is what really matters.
