TM 1-1510-223-10 Change 3          8-25 NOTE The maximum rate of climb performance is ob- tained  by  setting  maximum  continuous  power and maintaining two-engine climb speed. 1.   Climb power — Set. 2.   Propeller synchronization — As required. 3.  Yaw  damper  —  ENGAGE  (required  above 17,000 ft). 4.  BRAKE DEICE switch — As required. 5.  ICE   VANE   CONTROL   switches   —   As   re- quired. 6.  STANDBY PUMP switches — As required (re- fer to Chapter 5). 7.  Cabin  pressurization  —  Check.  Adjust  rate control knob so that cabin rate-of-climb equals one third of aircraft rate-of-climb. 8.   Wings and center section — Check for security and no fuel/oil leaks. 9.   Flare/chaff dispenser safety pin — Remove, as required. 10.  ASE — As required. 11.  Radio altimeter — As required. 8-28.   CRUISE. Refer to Chapter 7 for airspeed, power settings, and fuel flow information. The following procedures are to be used for Cruise configuration: 1.   Power — Set. 2.  ICE & RAIN switches — As required. 3.  AUTOFEATHER — As required. 4.  Auxiliary fuel gages — Monitor. 5.   Altimeters — Check. 6.   Engine instrument indications — Noted. 7.   RECOG lights — As required. 8-29.   DESCENT. Descent  from  cruising  altitude  should  normally  be made by letting down at cruise airspeed with reduced power (Refer to Chapter 7 for performance data). NOTE Cabin    altitude    and    rate-of-climb    controller should be adjusted prior to starting descent. If  required to descend at a low airspeed (e.g., to con- serveairspaceorminimizeturbulence),approachflapsand landing gear may be extended to increase the rate and angle of descent while maintaining the slower airspeed. 8-30.   DESCENT-ARRIVAL. Refer to Chapter 7 for performance data. Perform the following checks prior to the final descent for landing: WARNING V_mo may be easily exceeded when descending from  high  altitude.  The  pilot  should  frequently cross  check  the  airspeed  to  avoid  exceeding V_mo. Exceeding V_mo could  result  in  structural failure and loss of airframe integrity. 1.  CABIN CONTROLLER — Set. 2.  ICE & RAIN switches — As required. 3.  Windshield anti-ice — As required. CAUTION Set windshield anti-ice to NORMAL or HIGH as required  well  before  descent  into  icing  condi- tions or into warm moist air to aid in defogging. Turn  off  windshield  anti-ice  when  descent  is completed to lower altitudes and when heating is no longer required. This will preclude possible wind screen distortions. 4.   RECOG lights — On. 5.   Altimeters — Set to current altimeter setting. 6.  Radio altimeter — ON. 7.  ASE — As required. 8.  Flare/chaff dispenser safety pin — Insert. 9.   Avionics  and  EFIS  display  controller  —  Set and check. Ensure EFIS displays match pro- cedure to be flown. 10.   Arrival briefing — Complete.
