DIAGRAM 32.26
Reduced Thrust Take-off – Assumed Temperature Method There may occasions where the actual brake release mass is significantly lower than all of the limiting take-
off masses, and a lower thrust setting may therefore be used to safely complete the take-off. One method of
determining how much thrust reduction is available is to compare the limiting take-off temperatures for the
actual brake release mass. The lowest of these limiting temperatures may then be used as a basis for thrust
reduction.
Note that thrust reduction must not be used under the following conditions:
• Icy or very slippery runways
• Contaminated runways
• When certain aeroplane systems e.g. anti-skid are inoperative
To obtain the ‘Assumed Temperature’ thrust reduction value, first determine the most limiting (i.e. the lowest)
maximum temperature for each of the following:
• Field limit graph
• Climb limit graph
• Obstacle clearance limit graph
Next determine the maximum assumed temperature from the following table:

Fuel and Speed Adjustments
• Increase/reduce fuel used by 0.5% per 10˚C above/below ISA.
• Increase/reduce Mach number by 2% per 10˚C above/below ISA.
• Add 15kg fuel used per 1,000 feet of cruise climb.

Descent Time and Distance Adjustments
• No temperature adjustment need be considered.
• Add/subtract 3% of distance per 10 knots of tailwind/headwind.
• For overweight landings, use the 55,000kg data.
• For CI = 0 descent add 1.5nm per thousand feet above 10,000feet.
• For engine anti-ice during descent add 50kg of fuel.
• Above information is for a ‘straight-in’ approach - add 400kg and 10 minutes for a full instrument approach.
