carried without the use of the HICHS, this system expedites the loading and unloading process.
(e) Winch/hoist system. The CH-47D is equipped with a 3,000 pounds capacity hydraulically
operated winch that can be employed in either of two modes. For the purpose of loading and
unloading cargo internally, this system is used in the CARGO mode. This mode permits the
winching of cargo up to 3,000 pounds on a straight-line pull, or up to 12,000 pounds. with the aid of
pulley blocks. The remaining mode, described as the RESCUE mode, permits the use of this system
as a rescue hoist (up to 600 pounds) and is not used for cargo loading.
b. Limitations.
(1) CH-47D endurance is 2.5 hours without ERFS tank(s) and 4.0 hours with one ERFS tank installed.
(2) The combat radius of the CH-47D is approximately 225 kilometers.
(3) The combat radius of the CH-47D, with one ERFS tank installed, is approximately 350 kilometers.
(4) The aircraft shall not be started or shutdown in winds (including gusts) in excess of 30 knots.
(5) Continuous flight in light-icing conditions below 5 degrees C is not recommended since blade damage
can occur from asymmetric ice shedding.
A-4. UH-1H
This section discusses aircraft characteristics, capabilities, and limitations of the UH-1H helicopter.
FM 1-113 Appendix A
A-4
a. Characteristics.
(1) The UH-1H is a single engine, single rotor helicopter. Primary mission capability of the helicopter is
air movement of supplies and personnel. Secondary missions include SASO, air assault, and C2 operations
under day, night, visual, and instrument conditions.
(2) The aircraft is approximately 57 feet long with a 48-foot main rotor span.
(3) Maximum gross weight is 9,500 pounds.
(4) Maximum airspeed is 124 knots (roof mounted pitot tube) or 112 knots (nose mounted pitot tube), with
a normal cruise speed of 100 knots. However, the speed for any mission will vary greatly depending on
the load configuration, time of day, and weather conditions.
(5) The minimum crew for tactical operations is three, two pilots and one crew chief.
(6) The aircraft can be operated in IMC.
b. Capabilities.
(1) The UH-1H cargo hook can carry external loads up to 4,000 pounds.
(2) With seats install, the UH-1H can carry up to 11 combat-loaded troops.
(3) Aircraft internal loads can be up to maximum gross weight, with a limitation of aircraft space and
loading not to exceed 100 pounds per square foot.
c. Limitations.
(1) The UH-1H endurance is approximately 2.5 hours without auxiliary fuel tanks and approximately 6
hours with auxiliary fuel tanks. Note: The auxiliary fuel tanks in the UH-1H are mounted internally,
which reduces the passenger and cargo carrying capacity of the helicopter.
(2) The aircraft shall not be started with winds in excess of 30 knots or a gust spread of 15 knots or
greater.
(3) Intentional flight into known moderate icing conditions is prohibited.
(4) Intentional flight into moderate turbulence is not recommended. Flight into severe or extreme
turbulence is prohibited.

APPENDIX B
INITIAL PLANNING CONFERENCE CHECKLIST
B-1. PURPOSE
The purpose of this appendix is to provide a suggested format of an example checklist for air assault planning. This
checklist should be used by the aviation battalion staff during the IPC, the first step in the development of the air assault
plan. This checklist is designed to assist the aviation battalion staff in developing critical information needed by both
the aviation task force and the AATF. The information gained in the IPC will be used to develop the aviation OPORD
and AMB.
