Would you basically require a glass cockpit and autopilot to be able to fly?
Have seen solo students in VFR conditions declare because the glass-panel display in the trainer went out. Comm's still up, a perfectly good set of "steam gauges" available, charts, a pencil, a compass on-board, and 35kg pilot wristwatch strapped to the budding aviator's arm.
All the CRM-training is worthless if the single-pilot ADM is flawed.
