Morning S-12,
If there was ever a 'definitive' answer to this topic, you have most certainly nailed it
One other thought that maules.com touched on, aside from a few high performance and complex aircraft that I no longer fly, I rarely have a clue
where my flaps are. Well.... I mean where as in what angle has been selected. Yes, most (but not everything) I fly has detents, but I don't go to a 'book' setting for anything, I just roll on what makes it 'right'. Many times in something that has detents, this means keeping a hand on the lever and the push button lock pressed to unlock. IMHO this is one advantage most electric flap set ups have over manual.
Most modern ag aircraft have electric flaps. I have flown these wired every way imaginable, and with the switch in every conceivable location . For my preference I prefer a switch that has a momentary 'down' position and a dedicated up position if it is on the throttle quadrant, and a momentary 'chinamans hat' if it's on the stick. Set up like this I have infinite range selection in the 'add flap mode' and minimal need for 'searching' for the flaps. The dedicated up on the quadrant is just because after the apex of the turn my need for flaps is over, so being able to just slap the switch up and free up my hand for the throttle / GPS/ etc is golden. On the stick it's a moot point, because at that point in the game my hand isn't leaving the stick. Here it takes some getting used to, because occasionally the stick and your flap switch are going opposite ways.
In most of the aircraft pertinent to this thread I prefer a johnson bar, because these aircraft are light enough that instantaneous flap manipulation can be better used. Overhead ones are very handy to use, but I suspect that the vast majority of wrecks in 'bush beaters' occur with the flaps down. My personal preference is to have the cockpit as clear as possible on landing and T/O, and I currently don't wear a helmet while flying GA, consequently, I won't be installing my flap handle overhead.
Take care, Rob
