Airspeed = 102 KIAS
Press Alt = 6,000 feet
Approx Torque = 70%
METHOD:
(1)
Enter chart at total distance .own and at fuel remaining, move to intersection and plot point. If point falls on or above fuel remaining line (adequate range), remaining fuel is adequate to complete the mission. If point falls below the fuel remaining line in the inadequate range, abort mission region, immediately return to departure point while continuing to utilize altitide pro.le using total elapsed .ight time (see item 2). If point falls below the fuel remaining line in the inadequate range, region, consult emergency procedures for corrective action.
(2)
To determine target nominial .ight conditions, enter upper chart at elapsed .ight time and move up to determine target airspeed, approximate torque, and pressure altitude.

NORMAL PROCEDURES
Section I MISSION PLANNING
8.1 MISSION PLANNING.
Mission planning begins when the mission is assigned and extends to the pre.ight check of the helicopter. It in-cludes, but is not limited to checks of operating limits and restrictions; weight, balance, and loading; performance; publications; .ight plan; and crew and passenger brie.ngs. The pilot in command shall ensure compliance with the contents of this manual that are applicable to the mission and all aviation support equipment required for the mission (e.g., helmets, gloves, survival vests, survival kits, etc).
8.2 AVIATION LIFE SUPPORT EQUIPMENT (ALSE).
All aviation life support equipment required for mission; e.g., helmets, gloves, survival vests, survival kits, etc., shall be checked.
8.3 CREW DUTIES/RESPONSIBILITIES.
The minimum crew required to .y the helicopter is two pilots. Additional crewmembers, as required, may be added at the discretion of the commander. The manner in which each crewmember performs his related duties is the respon-sibility of the pilot in command.
a.
The pilot in command is responsible for all aspects of mission planning, pre.ight, and operation of the helicopter. He will assign duties and functions to all other crewmem-bers as required. Prior to or during pre.ight, the pilot will brief the crew on items pertinent to the mission; e.g., per-formance data, monitoring of instruments, communications, emergency procedures, taxi, and load operations.
b.
The pilot in command must be familiar with pilot duties and the duties of the other crew positions.
c.
The crew chief will perform all duties as assigned by the pilot.
8.4 CREW BRIEFING.
A crew brie.ng shall be conducted to ensure a thorough understanding of individual and team responsibilities. The brie.ng should include, but not be limited to, pilots, crew chief, mission equipment operator, ground crew responsi-bilities, and the coordination necessary to complete the mission in the most efficient manner. A review of visual signals is desirable when ground guides do not have direct voice communications link with the crew.
