Table 4.5-5
At maximum take-off mass with the airbrakes fully extended and at
117 km/h (63 kts) the approach angle is approximately 1:6 (in calm
conditions). Any increase in airspeed increases the approach angle
significantly and at V
NE
without water ballast the descent angle is
approximately 45°.
CAUTION: When on final approach, do not change to a more
negative flap setting (for example, from setting L to
setting 4) without sufficient airspeed as the resulting loss
of lift will cause a significant loss altitude.
NOTE: Always lower and ensure that the landing gear is locked,
especially in the case of an emergency landing.
