...We're now on our fourth airplane and the first one with an autopilot, and it is a tool we have learned to add to our "bag of tricks". Definitely a help when single pilot IFR, but you'd better be carefully monitoring what "George" is doing, since you are still PIC and totally responsible for the outcome of the flight.
Bingo - right answer.
Personally, as far as autopilot usage while IFR goes, I would like to believe that we can all hand fly all the various types of instrument approaches down to their respective minimums correctly and proficiently without any type of aid - flight director, autopilot, etc. If a pilot cannot do that, then he needs to get more training or quit flying IFR - period. The autopilot is designed to be a pilot aid, not a pilot's crutch. That being said, aircraft owners spend great sums of money to provide redundancies for nearly every system on our aircraft - multi engines, dual this, triple that, etc., etc. Here's a question. When we hand fly an ILS approach down to minimums, what redundancy to we have in case of "pilot failure"? In aircraft with two-pilot crews, if the pilot not flying is doing his job, will he be able to effectively take the controls in the case of a botched approach by the pilot flying? Obviously not, and even if he was able to, is solid IFR at 200' AGL and with a 700 fpm sink rate the time and place to be making those types of changes? What about us when we're flying single-pilot IFR? Where's the redundancy? There isn't any.
Personally, I believe that we should hand fly all of the "high and mid" minimums approaches we can, but when the ceiling gets below 500 feet and the visibility gets below a mile couple it up and let the autopilot do its thing. We then become the backup to the autopilot and we have injected an element of redundancy into the operation. In that rare case that the autopilot messes up and gets us sideways to the world, relief is only a click of the autopilot release button away. In the mean time, you have been able to, as Nightowl alluded to, watch and monitor the approach while covering the controls. If it ever becomes necessary, the transition is both instantaneous and seamless.
Here is another item to consider…
We frequently use contract pilots in our flight department. A while back, I had the opportunity to fly with one who subscribed to the theory that "real" pilots don’t use autopilots. It was his leg and we were departing one of the LA basin airports. It was one of those “minimum VFR" days and light aircraft were out buzzing around like mosquitoes in Minnesota. It was a busy day and this guy did a masterful job of hand flying the departure procedure and working with ATC. The problem was that he had his head buried in the cockpit flying the airplane and not looking outside. We have all flown with those hairy chested pilots who say that "real" pilots don't use autopilots. These are the guys who compulsively and habitually hand-fly the airplane at all times except during cruise, including all approaches. Personally, I think that’s not a good idea. Real pilots know when to use autopilots and when it’s best not to. We're just not talking during approaches either. There are other times when we probably have no business hand flying our aircraft. For example, VFR weekends in the Phoenix/Scottsdale area or L.A. basin below 10,000' MSL. Can you really hand fly your airplane aircraft while maintaining an adequate watch for traffic or are you one of those guys who puts 100% faith in his TCAS or ATC? Remember, the basis for traffic separation is still “see and avoid”.
As always, this is just my personal opinion and YMMV.
