CRUISE TABLES
The long range cruise and maximum speed cruise tables show N1,
fuel flow, indicated airspeed, true airspeed, indicated Mach number,
buffet margin and specific range. Data are presented for various
weights in ISA conditions and corrections for ISA deviation.
In the long range cruise schedule, all engines operating or one engine
inoperative, the airplane is flown at a speed corresponding to a
specific range equal to 99% of maximum specific range. It is used
when range is the principal factor.
In the maximum speed schedule, the airplane is flown in a speed
resulting from maximum cruise power setting. It is used when
minimum flight time is desired.
Thrust selection in cruise condition is adjusted to CRZ mode. The
climb to cruise transition should be made as follows:
- After reaching the cruise level, allow the airplane to
accelerate past 0.60M, before selecting cruise mode.
- When in cruise mode, adjust thrust to keep N1 or cruise
speed constant (whichever occurs first).
The associated conditions are:
- Flaps.....................................UP
- Gear......................................UP
- Bleeds...................................OPEN
- Anti-Ice .................................ON (Engine or all)
NOTE: The corrections (N1, Fuel Flow and TAS) given in the Long
Range Cruise and Maximum Speed Cruise tables are
applicable only to ISA -15°C to ISA +15°C range.
