. When flight path is safe and GPWS warning has ceased :
°. Decrease pitch attitude and accelerate
. When speed above V LS and V/S positive :
°. Clean up aircraft as required

Introduction
A rejected landing (also referred to as an aborted landing) is defined as a go-around maneuver initiated after touchdown of the main landing gear or after bouncing.
Although a rare occurrence, a rejected landing is a challenging maneuver decided and conducted in an unanticipated and unprepared manner.
The objective of this Briefing Note is to define:
.
Applicable decision criteria for: -Full-stop landing; or, -Rejected landing and go-around; and,
.
Procedures and techniques for bounce recovery, including:
-Continued landing; or,
-Rejected landing (i.e., go-around).
Statistical data
No global statistical data are available on rejected landing incidents or accidents but the following three events illustrate the circumstances that may lead a flight crew to reject the landing, and the possible consequences of such a maneuver:
.
Tail strike following a go-around initiated due to directional control difficulties after thrus t reverser selection;
.
Climb performance limitation following the undue selection of reverse thrust during a touch-and-go and failure of one reverser to stow; and,
. Loss of control following a go-around initiated after thrust reverser selection (because of a vehicle obstructing the runway) and failure of one reverser to stow.
Touch-and-go ( training only )
Although a touch-an-go is essentially a training exercise, the conditions required for the safe conduct of this maneuver provide a valuable introduction to the discussion of rejected landings.
Preconditions:
Four preconditions (usually referred to as the “4-No rule”) must be observed prior to initiating a touch-and-go:
.
No ground spoilers:
- ground spoilers must not be armed or manually selected after touchdown;
.
No autobrake:
- autobrake must not be armed;
.
No reverse:
- thrust reversers must not be selected upon touchdown; and,
.
No pedal braking:
-pedal braking must not be used after touchdown.
Performing a rejected landing in revenue service (i.e., with ground spoilers and autobrake armed, being ready to select reverse thrust upon touchdown) creates an added challenge.

Aircraft reconfiguration:
After touchdown for a planned touch-and-go, the aircraft must be reconfigured to a takeoff configuration:
