Yeah, fair enough, for my few landings in a Beaver, I've selected "Landing" flap. Similarly, when I was being checked out on the Twin Otter, I was limited [by the check pilot] to 20 flap until I'd demonstrated my awareness of the effects of 40 flap. My statement was in the context of Cessnas, as being discussed...Full flaps on a Beaver, hmmmmm
I'd suggest that flap 40 may not be in ones best interest when landing in the above mentioned conditions!
By not using full flaps, you are possibly landing faster, and putting more stress on the whole rest of the airframe during landings, particularly rough water landings. The flaps were designed to be used. Like the entire airframe, sometimes maintenance will be required.By always using full flaps on a 180 or 185 are you putting a lot of unnecessary stress on flap tracks, rollers, bushings, cables, etc?
The drooping of the ailerons with a Robertson STOL kit is not exactly like a DHC2-3-6. Yes, they droop with flap extension, though their greatest droop is with 30 flap, and they begin to return to lesser droop when 40 flap is extended to assure roll control is optimum. If you are slowing down into the slow side of approach speed with more than 20 flap extended in a Roberston STOL Cessna, you already have satisfied yourself that full roll control will not be needed. If conditions are such that you may need full roll control (gusty conditions, or unpracticed pilot) you should avoid getting too slow. RSTOL Cessnas do not lack for roll control, though careful coordination of the rudder is vital.The c185 with a Robertson STOL droops the ailerons in the same or similar fashion as the DHC2-3-6 ......during gusty winds,rough air conditions,or Xwinds....Roll control is compromised....
I own and fly a Robertson STOL equiped unit....the STC and the way the ailerons droop or retract are in the manual and operate as you mentioned....rudder or no rudder,roll control is compromised to various degrees depending on conditions...how can it not be when you consider airflow and aileron positioning.
Your comments on roll control and/or "rudder recovery" would work in a perfect world! its not perfect!
Some commercial company's operating Beavers instruct pilots not to use full landing flap.....poor aileron control perhaps...how slow do you need to go??
Flaps brakes etc are all there to be used.....so are the fuel tanks but do we fill them up every flight????
Cessna put various degrees of operating ranges on their flaps......use what works best for you under the daily varying conditions as per the manual!
The use of flap varies with conditions and pilot abilities....that's one reason for the different available setting.....
Absorb the info being offered and discard hard line or radical opinions!
Don't forget that the POH has good info!!
I intend to be in the Tazin River late June .......are you in that area??
All very helpful.
The Tazin river is my old moose hunting area when I used to live in Ft Smith.
I moved back to Yellowknife in 2005 and no longer fly in that area but it is still one of my favorite hunting spot.
