Soft field takeoff and landing

Objective

Develop a pilot’s ability to execute soft-field takeoffs and landings, safely clearing any obstacles.

Elements

Soft-field takeoff
  • performance calculations
  • configuration
    • flaps 25°, wind correction
    • full-aft controls
  • taxi without stopping into takeoff position
    • advance to full power as runway lines up
  • lift-off considerations
    • hold the nose off promptly, avoiding stall horn
    • weathervaning tendencies increase as nosewheel lifts
    • turning tendencies
    • crosswind correction
  • as nose lifts, reduce backpressure until mains are off
  • remain in ground effect
    • forward pressure will be needed
  • allow aircraft to climb as Vx (72) or Vy (78) is reached
    • pitch for initial climb attitude and airspeed, +10/-5
    • retract gear when positive rate, no usable, clear of obstacles
    • flaps out gradually with safe altitude
  • climb power at 500 ft, pitching for cruise climb (104)
  • climb checklist
Soft-field landing
  • performance calculations
    • wind conditions, obstacles (intersecting runways?)
  • configuration
  • touchdown point 200 ft from threshold and within first third
    • consider a go-around point as well
  • stabilized approach to touchdown (1.3 Vso, +10/-5)
    • coordination
    • precise ground track
    • calculated airspeed prior to threshold to avoid float
    • final checklist
  • nose-high pitch attitude 10-20 ft
    • carry some power until around flare
    • aligned with centerline on touchdown
  • hold nose off, touching slowly to prevent digging in
  • directional control
  • power as needed to maintain forward movement

Instructor Actions

In a guided discussion, explain the aerodynamics, procedures, and execution for soft-field takeoffs and landings, using whiteboard illustrations and a model aircraft.

Student Actions

Read appropriate chapter and complete homework assignment prior to the briefing. Participate in the guided discussion.

Standards

The student should be able to explain the aerodynamics, procedures, and execution for soft-field takeoffs and landings.
