For the landing with Flaps DOWN enter the Vref
speed, 98 KIAS at the appropriate place on the TOLD.
(16) Vapp Speed. This is the intended final
approach speed. It is Vref plus 20 KIAS for a normal
instrument approach; Vref plus 10 KIAS for a stabilized
approach; and, Vref plus 10 KIAS for a visual approach
as determined by the PC.
For this example, the landing is planned with the
Flaps DOWN (100%) so the Vref is 98 KIAS. The
weather conditions are such that a normal instrument
approach back into the departure airport is planned in
the event of a takeoff emergency. Therefore, the Vapp
will be Vref plus 20 KIAS.
Vref is 98 KIAS + 20 KIAS = Vapp 118 KIAS.
Enter this speed in the appropriate block on the TOLD
card.
(17) Landing
Distance.
The
distance,
measured from the landing touchdown, required to
land the aircraft and stop. Use Figure 7-30, Landing
Distance Without Propeller Reversing - Flaps 100%.
NOTE
Do not use a headwind or headwind
component in calculating landing distance.
But, if a downwind landing is required,
then ensure the tailwind is factored.
Enter
the
chart
at
the
OUTSIDE
AIR
TEMPERATURE ~ ºC, +30 ºC. Trace up until
intersecting the correct PRESSURE ALTITUDE ~
FEET line, 4000 feet. Trace horizontally to the right
until intersecting the first REFERENCE LINE.
Maintain the same relative position between the
guidelines and trace down until intersecting the aircraft
weight line. From that point, trace horizontally to the
DISTANCE ~ FEET scale to determine the landing
distance.
For this example, the landing weight is 12,400
pounds. Assuming a takeoff emergency, the landing
weight may exceed the landing weight limit of 12,500
pounds.
The landing distance is 2,120 feet.
Enter that number, 2,120 feet, in the appropriate
block of the TOLD card. Remember, if the landing is
planned for touchdown to be at the 1000-foot markers,
then 3,120 feet will be required to accomplish this
landing with full flaps. Refer to Figure 7-4 for an
example of a completed TOLD Card front.

g. Performance
Planning,
Cruise.
Recommended Cruise Power, 1700 RPM charts
beginning at Figure 7-38 are normally used for cruise
performance planning. Use Figure 7-11, ISA
Conversion, to determine the correct chart, relative to
ISA, for cruise performance planning. For this
example, the mission is planned to be flown at FL240.
(1) If a weather forecast provides the
forecast temperature at the cruise altitude, enter
Figure 7-11 at that temperature. Trace up until
intersecting the planned PRESSURE ALTITUDE ~
FEET. At that point, determine the closest ISA +/-
guideline and use the corresponding chart for
planning.
If the forecast temperature for FL 240 is –10 ºC,
enter the chart at that temperature. Trace up until
