Knowing my personal limitations with computers, I no longer teach instrument flying. Even the radio is computerized.
In contact flying, contact with the earth is essential. If we will lose good contact at 100', we need stay below 100'. No exceptions. No integration of instrument with contact. Integration kills.
Upon losing contact with the earth, we become totally dependent on instrument indications. We also have to totally believe the cross check of instrument indications. That is why dual source of basic instrument indications and pitot static test is necessary to achieve safe unquestionable belief. No exceptions.
For the non trained or occasional actual instrument pilot, this is more important than for the regular IMC guy.
In my thinking, questionable instrument indications are less safe than no instrument indications for those of us who do not fly IMC regularly. And for me any computer generated instrument indication, without a young instrument pilot beside me, is questionable.
