Man-machine interface and anomalies

[RR_NDB]

Basic requirements of the Interface

Hi,

The Interface should be:

1) Simplest possible (K.I.S.S. design rule)

2) Allow the crew ALWAYS be capable to control the plane, when required

3) Allow the crew to be ALWAYS "ahead" of the plane

4) Always Help the crew

5)Capable to orient crew how to better enter the loop to act better (fast, precise, etc)

6) Keep crew ALWAYS ready for ANYTHING

7) ALWAYS inform on "what's doing (protecting, processing in background, etc.)

The interface additionally must be:

1) Always reliable for inputs from crew and outputs (inputs to the crew)

2) Never mislead the crew

3) Provide properly most important indications to allow a safe aviate

4) Allow immediate interventions as required by circumstances

5) Allow "recover of what happened" (for design feedback, diagnostic, etc.)

If i missed something, please include it.

Questions:

1) This is what we should expect from the Interface?

2) The Interface used in A320, 30, 40 and 80 have this characteristics?

3) If not, Why?
