Well you have to be ready for it. The iPad has to be mounted and can’t be moved, you have to have the internal or external AHRS aligned, the GPS set up, plugged into power, etc etc.
When your PFD fails and you have 9 checkride failures and you can’t even be bothered to look at the standby on the other side of the cockpit while hand flying I don’t this guy had the mental bandwidth to set up a iPad for survival.
FWIW, pretty common in big jet 135, but that’s because we’re nerds and had a big budget.
This operator couldn’t be bothered to MEL and fix the MFD which was required for single pilot ops but they had a video camera in the cockpit.
Things that make you go “huh”
