Maybe some of the below may stimulate some discussion,
Just a few points to consider in STOL type operations:
AIRCRAFT:
Familiarity with aircraft, particularly across lower end of envelope, use of rudder, particularly good secondary control.Mastering power and attitude balance. Operating at the back of the drag curve, ground clearance.
ENVIRONMENT:
Legality ALA's vs 500" min, micrometeorology(big subject!), familiarity,walk or drag the location, time of day operations, density altitude, reading terrain, recognising obstacles, One way operations.
SKILLS:
Flap application, sideslipping, soft field short field techniques,taxiing obstacle avoidance, upslope landing.
Getting in and getting out present different dangers and challenges. No matter who you talk to most will tell you that it's practice, practice. Start in familiar environments and narrow down your parameters there first. SAFETY is No1- if in doubt don't do it. We often do PFL refreshers and BFR's and pilot's soon realise how rusty they get in these areas. Done right it opens up many opportunities and rewards. I'll watch with interest further replies to this thread also.
