Maximum stopping margin allows the user to limit the calculation of
V
1
MIN as follows: as actual takeoff weight is reduced below the FLLW,
the calculation of V
1
MIN proceeds normally; at the point where the
specified stopping margin is reached, the calculation of V
1
MIN is
governed by the stopping margin, i.e., V
1
MIN is increased in order to
keep the stopping margin. V
1
MIN will not be allowed to be greater than
V
1
MAX (V
R
or V
MBE
).
TAKEOFF FIELD LENGTH - WET AND CONTAMINATED RUNWAY
When “Airport Analysis” calculation type is selected, the wet or
contaminated runway takeoff performance is compared to the dry
runway takeoff performance, and the lesser takeoff weight is taken as
the maximum field length limited takeoff weight.
When “Given Weight” calculation type is selected, the wet or
contaminated runway takeoff performance is not compared to the dry
runway takeoff performance. The resulting distances refer exclusively
to the requested wet or contaminated runway takeoff performance.
TAKEOFF FROM GROOVED OR PFC RUNWAY
Airplane operators who wish to use the grooved or PFC runway
accelerate-stop distances must determine that the design,
construction, and maintenance aspects are acceptable for each
runway for which such credit is sought.
The airplane operator must coordinate with each Airport Authority in
order that appropriate standards are complied with.
GRADIENT LOSS IN TURN
Gradient loss in turn after takeoff is supplied by the CAFM, either for V
2
wi
th takeoff flaps or for V
FS
with flaps up.
Landing gear may be retracted or extended, and thrust may be Takeoff
Thrust or Maximum Continuous Thrust, with all engines operating
(AEO) or one engine inoperative (OEI).
