INTERMEDIATE FLIGHT PREPARATION WORKBOOK
APPENDIX H
maximum range cruise airspeed by 0.01 true M. For every 25 KTS of headwind component,
increase the maximum range cruise airspeed by 0.01 true M. For every 25 KTS of tailwind
component reduce the maximum range cruise airspeed by 0.01 TAS M. These modifications to
airspeed are valid only for maximum range missions. They are not valid for missions at
minimum enroute time or maximum endurance.
Anti-Ice
The operation of anti-ice systems will result in reduced range. The specific effects on cruise
performance will depend on the selected cruise thrust setting. If the setting is less than the
MCRT setting for anti-ice on configuration, the required %N1 and cruise speed can usually still
be obtained, but cruise range will be decreased by a factor ranging from 3% with engine anti-ice
on, to 5% with all anti-ice systems operating. For cruise at MCRT, the maximum obtainable
cruise speed with anti-ice on will be less than the maximum speed with anti-ice off, and range
will decrease by a factor ranging from 3% with engine anti-ice on, to 5% with all anti-ice systems
on.
Gear Down Cruise
If it is necessary to cruise with the landing gear extended, the maximum airspeed and altitude are
200 KIAS and 20,000 feet. This configuration imposes a loss of 40% in range and 30 KIAS in
airspeed on the 2-engine maximum range performance.
H105. DECENT SPEEDS AND CONSIDERATIONS
Maximum Range
Idle power, clean configuration. Above 35,900 feet, establish IMN of 0.70. Below 35,900 feet,
establish IAS of 230 KIAS.
Enroute
Idle power, speed brakes extended. Above 32,300 feet, establish IMN of 0.70. Below 32,300
feet, establish IAS of 250 KIAS.
Penetration
CAUTION
This descent profile is only used below 20,000 feet due to landing
gear extension limitations.
Retard throttles to IDLE, or as required, and use speed brakes as necessary to descend and
decelerate. At or below 200 KIAS extend the landing gear as desired. With idle power, speed
brakes and landing gear extended, and a speed of 180 KIAS, establish a pitch attitude on the
