Basic philosophy
Nice concept, Bubs.
Although my IP had explained a lot about AoA and lift and such, on my first flights he taught me to use pitch attitude looking at parts of the canopy rails and such. Hold an attitude at a power setting and watch airspeed. Slowing down? Lower the nose a bit, and vice versa.
There are few planes in the commercial arena that will suffer catastrophic failure if you simply "hold what ya got" if you have any warnings except terrain collision. Sure, complete loss of power such as Sully had requires keeping airspeed for maneuvering and such by lowering the nose. But even my LEF emergency only required that I keep doing what I was already doing ( lots of sidestick pressure to keep roll under control and yaw trim would come later).
Another pilot here has already commented that the nifty flight director bars helped to get on course or intercept the ILS or...... But I can tell you that when I got my interceptor assignment outta pilot training that the Air Defense Command liked those of us that had flown the old T-33. No fancy ADI or steering or such when on instruments. "Primitive" would be a good description. So they let us fly target missions and such after only a single checkride. The T-38 troops had to wait until they were at their permanent assignments.
First jet I flew with the steering bars was the SLUF, and it was very "loose". Most of us did better using the raw data, heh heh. Years later I got to the Viper and no steering, just raw data( see my video of the LEF landing approach). Hmmmm.....
Somewhere in the aftermath of this tragedy, the powers that be must take a deep breath and implement better training. Ya think?
