GENERAL
FAA Approved
Original Issue: Feb 28, 2006
Associated Conditions
NOTES:
1. When engine antice bleed is in use, add 0.5% N
1
to the % N
1
given by the chart.
2. For flaps 15°, add 5% N
1
to the % N
1
given by the chart.
3. The pressure altitude at which it is intended to reduce power must not be less than
1000 feet above the airfield altitude.
4. Below maximum take-off weight, the same RPM (% N
1
) setting will result in a
higher rate of climb than quoted above.
5. This technique is similar to that used in the noise abatement climb procedure used
for type certification demonstration.
Instructions for Use of Charts
To determine the % N
1
required:
• Determine the pressure altitude at which it is intended to reduce thrust i.e., field pressure
altitude plus the height above the airfield level at which the thrust reduction is to
commence.
• Enter the appropriate chart with the airfield temperature.
• Proceed vertically to the field pressure altitude.
• From this point move parallel to the nearest line of constant temperature relative to ISA
until the pressure altitude for thrust reduction is reached. Read the % N
1
required.
• For temperatures below ISA -20
°
C, use the value of % N
1
appropriate to a temperature
of ISA -20
°
C
.
POSITION ERROR CORRECTIONS
The position error corrections (PEC) to both airspeed and altitude are given for the normal
system acting through the air data computer (ADC) and AFD and also for the alternative system
which is applicable to the ESIS airspeed and altitude. The flaps retracted curves below 160
KIAS and the flaps extended curves are not applicable to indicated altitudes greater than
14,000 ft.
Airspeed Correction for Take-off Ground Roll
The airspeed correction to be used during the takeoff while still on the ground is given in Figure
5.05.8A. This correction is to be made to IAS to obtain EAS.
