I lost my ASI at 13000', at night, single pilot IMC. Broke clouds at 400' on the ILS. No FD, let alone FMC. Not even a co pilot.
Another time on a ferry flight lost all airspeed during TO in a A310. Came VMC at 10.000'.
In both cases I relied on raw data and hand flying. Worked as advertised without indept knowledge of non technical CRM skills.
Have to say though, that where I come from, we spend 60 hrs in a Frasca box before we were even allowed to take up IFR training in an airplane.
Nowadays I see so called airline pilots with 'frozen ATPL's, MCC courses, Jet conversions and what have you not, not being able to determine a holding entry raw data.
The industry invented many gadgets to make flying easier.
Problem is that pilots nowadays rely on it 100%.
And I strongly disagree that one learns to fly by watching an autopilot fly.
