I've only ever had to operate 2 sectors on the 737 without the AP and we still had the FD and AT.
If that's an acceptable argument, then why do we similarly "waste" time with training for engine failures, given that modern engines are very reliable as well
Because its done in the sim not on the line with passengers in the back.
you're kidding yourself if you think that hand flying enhances safety because the opposite is true.
Perhaps you might cite some objective evidence to support such a wide-sweeping statement. Certainly, in some circumstances we would all acknowledge that it makes more sense to drive with the automatics on. However that doesn't cover all bases ....
From a CRM or threat and error management standpoint I find it hard to justify throwing away around half a pilot's worth of resources ( only an estimate IMHO) to better prepare oneself for an AP or FD failure. I did not imply that hand flying was unsafe and it might even be worth accepting a slight degradation of situational awareness by the crew to maintain handling skills. My view is that I can operate to the highest level of safety by making full use of the automatics and that is what the passengers have a right to expect.
