"I would love to see what happens when that whizz bang GPS goes u/s"
Come on Baz, your just jerk'in my chain aren't you.
The Mad Dr is flying along at A090 in the soup and his whizbang GNS430 craps itself!
What's he going to do?
1) Look at the GPSMap296 on the yoke
2) Use the ADF and/or VOR
3) Pull the Garmin III Pilot GPS out of my flightbag and fire it up
4) Ask for radar vectors
5) Use the VOR on my Icom handheld VHF
6) Dead-reckon my way to VMC
7) Descent to VMC
8) Pull the power back to Max Range and hope to stumble into VMC before the donk stops
Even I could get to (4) or (5) before I would have to get the brain out of neutral.
Dr
