Section V Sub-section 1
NORMAL HANDLING
CLIMB
Refer to Figure 3 for a Flight Profile of Climb, Cruise, and Descent.
For the following procedures, refer to Section IV - FLIGHT PLANNING DATA.
Climb fuel, distance and time are tabulated versus take-off weight and altitude at top of climb.
The data is presented for temperatures in the range from ISA -15°C to ISA +20°C.
Tables are presented for two climbs:
•
Normal Procedure Climb ................................................ Section IV - Sub-section 3
The Normal Procedure Climb continues at 250 KIAS to 32,000 ft. at which IMN = 0.70.
The final part of the climb to cruise altitude is at IMN = 0.70.
•
Optimum Time-To-Height Procedure Climb....................Section IV - Sub-section 3
The Optimum Time-To-Height Procedure Climb continues at 250 KIAS to 28,000 ft. at which
IMN = 0.63. The final part of the climb to cruise altitude is at IMN = 0.63.
Both climb procedures include time and fuel allowances for takeoff and initial climb to 160 KIAS at 1000
ft, but no distance is credited for this initial climb. The procedures then accelerate to 250 KIAS at 5000
ft and continue to 10,000 ft at this speed. Maximum Climb Thrust is set by adjusting the thrust levers
until the green CLIMB annunciation appears in the N
1
/ITT gage (located at the lower center of the
N
1
/ITT scales on the pilot’s MFD).
NOTE:
When using the CLIMB annunciation in the N
1
/ITT scale to set Max Climb rating, the
achieved N
1
should not be more than 1% below the value determined from either the
Maximum Climb Chart or the FMS database. Deviation from the chart or FMS value is
dependent on individual engine compensation levels and the accuracy of the airplane
systems. If the achieved N
1
is more than 1% below the chart/FMS value, refer to the
troubleshooting procedures for "Low N
1
at Takeoff Power Setting" in the TFE731-5BR Light
Maintenance Manual.
Refer to Tables 1 and 2 for chart values.
The pilots need not check the Maximum Climb RPM against the chart unless they believe that climb
thrust is not being achieved.
Set climb power as soon as convenient after raising the flaps and landing gear, or after the completion
of a noise abatement procedure, and allow the airplane to accelerate to achieve the recommended
climbing speed at 2000 to 3000 ft.
If rate of climb is not important, a power lower than maximum climb power may be used.
When cruising height is reached, allow the airplane to accelerate to cruising speed and reduce power
to within the cruise rating. In some conditions, the initial cruising speed may be below the climbing
speed.
