It is possible to figure out what the alpha is with certain PFD settings, but for the main part commercial pilots are trained to follow flight directors and effectively be clueless about what is actually happening with the aircraft. IMHO it is mostly engineers who argue that alpha is not necessary; I've also been told by OEMs that it would be 'too difficult' for commercial pilots... The bottom line is that speed is only a proxy for alpha and a very large proportion of airline pilots that we fly during on-aircraft UPRT have to be taken back to basics in understanding how an aeroplane flies - especially with respect to the impact on alpha of relative airflow in a climb and a descent. Just as an aside, if you buy a new Cessna 172 Skyhawk, it comes with an Alpha gauge included! |

Or you could just insist everyone spends a couple years tooling around in a knackered old turbo prob with no Ap! Sorry that bus has already departed, hasn't it!
