Initial Climb - Ground Effect On Takeoff

On short-field takeoffs, the landing gear and flaps
should remain in takeoff position until clear of obstacles (or as recommended by the manufacturer) and VY
has been established. It is generally unwise for the pilot
to be looking in the cockpit or reaching for landing
gear and flap controls until obstacle clearance is
assured. When the airplane is stabilized at VY, the gear
(if equipped) and then the flaps should be retracted. It
is usually advisable to raise the flaps in increments to
avoid sudden loss of lift and settling of the airplane.
Next, reduce the power to the normal climb setting or
as recommended by the airplane manufacturer.

Common errors in the performance of short-field takeoffs and maximum performance climbs are:

• 
  Failure to adequately clear the area.
  
• 
  Failure to utilize all available runway/takeoff
  area.
  
• 
  Failure to have the airplane properly trimmed
  prior to takeoff.
  
• 
  Premature lift-off resulting in high drag.
  
• 
  Holding the airplane on the ground unnecessarily
  with excessive forward-elevator pressure.
  
• 
  Inadequate rotation resulting in excessive speed
  after lift-off.
  
• 
  Inability to attain/maintain best angle-of-climb
  airspeed.
  
  
  
  
• 
  Fixation on the airspeed indicator during initial
  climb.
  
• 
  Premature retraction of landing gear and/or wing
  flaps.
