On a short, soft field with an obstacle, you must perform
Choices
no special technique.
Definitely a special technique required.
✓ the SHORT-FIELD-OVER-OBSTACLE technique combined with SOFT-FIELD elements: full back elevator from the start (soft-field), full power held against the brakes (short-field), and rotation as early as possible.correct
Then accelerate in ground effect and climb at Vx to clear the obstacle before transitioning to Vy. Combined short/soft technique: back elevator throughout to keep weight off nosewheel (soft), brakes-held full power (short), early rotation at low IAS (soft), then level off in ground effect to accelerate to Vx (rather than Vy because of obstacle). Climb out at Vx until clear of obstacle, then Vy. POH governs specifics; many trainers don't have explicit combined procedure but pilot must integrate the two.
use a tailwind for takeoff.
Tailwind on a short field is suicidal.
skip the runup.
Runup is mandatory regardless of field.
