provide go-around guidance commands throughout the maneuver.
If a go-around is initiated after touchdown but prior to thrust reverser selection,
auto speedbrakes retract and autobrakes disarm as thrust levers are advanced. The
F/D go-around mode will not be available until go-around is selected after
becoming airborne.
Once reverse thrust is initiated following touchdown, a full stop landing must be
made. Factors dictating this are:
• five seconds are required for a reverser to transition to the forward thrust
position
• a possibility exists that a reverser may not stow in the forward thrust
position.
Normal Touchdown Attitude
The following figures illustrate the effect of airspeed on body attitude on
touchdown. It shows normal touchdown attitude for flaps 30. If flare control and
thrust are excessive near touchdown, the airplane tends to float in ground effect.
With proper airspeed control and thrust management, touchdown occurs at no less
than VREF - 5. The illustration shows that touchdown at a speed significantly
below VREF seriously reduces aft fuselage-runway clearance.
