Description:
To a short runway, one with obstacles, or both, pilots must precisely control inputs to produce a rate of descent and airspeed resulting
in no floating during round out and the shortest stopping distance.
Common Errors:
•
Unstable approach (excessive descent rate or airspeed)
•
Low airspeed resulting in flare inability and a hard landing
•
Poor power management, resulting in hard landings
•
Excessive braking (lock ups)
•
Failure to maintain directional control
•
Failure to abort an unsafe approach

Landing...................................................................... On Pre-Specified Point/ Just Beyond
Description:
This approach is executed by gliding with the power off from the downwind leg to a preselected landing spot or 200 feet beyond. The
objective is to instill good judgment and procedures necessary for accurately flying without power.
Common Errors:
•
Downwind leg is too far from the runway
•
Overextension of the downwind leg due to tailwinds
•
Inadequate crosswind compensation
•
Uncoordinated turns
•
Failure to lower landing gear
•
Premature flap / landing gear extension
•
Attempting to “stretch” gliding distance
•
Using the throttle
•
Forcing the airplane on to the runway to avoid overshooting the landing spot
