The load analy
32、sis charts are used to determine the total load requirements for each condition under which the aircraft operates. The operating conditions listed in the following paragraphs are considered typical for most military aircraft. The conditions shall be reported and analyzed in the order corresponding t
33、o a typical operation of the particular aircraft. Special conditions applicable shall be reported in additional operating condition columns. The charts for each operating condition shall be designated G1, G2, G3 . . . consecutively for a normal operating sequence. See Figures 5 and 11 for sample loa

The electric loads reported shall include the maximum power requirements of all loads or groups of loads which may be operated
35、simultaneously during maintenance operations. 3.5.4.2.2 Calibration. Calibration is that period when equipment is beix checked for- accuracy or recalibrated. Exception: The condition of calibration may be omitted when each electric equipment in the aircraft can be calibrated with, (1) power having t
36、he characteristics specified in M.L-STD-704, and (2) the ground power source required for the ground maintenance Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-E-7016F condition is also adequate for calibration power. in lieu of the Y!alibration
37、fl entries, a statement that both of the above requirements have been fulfilled shall be included in the notes. 3.5.4.2.3 Loading and preparation. Loading and preparation is that con- dition between securing and starting. Operations performed during this period may consist of hoisting, fueling, ligh
38、ting, radio communications, heating, cooking, etc. During this period, power is supplied by an auxiliary power unit, internai batteries, or an external power source. 3.5.4.2.4 Start and warmup, Start and warmup is that condition from pre- paration for starting to taxiing. An example of an engine sta
39、rting analysis is given in Figure 16, Exceptions: a. Equipment warmup: If certain equipments require extended or otherwise special warmup prior to routine flight operations, the addi- tional condition of flEquipment warmupfl shall be reported. b. Electric-powered start: For aircraft utiliz- ing elec
40、tric power for engine starting, a separate detailed analysis shall be made to define starter input power requirements. When the main engines are started by exter- nal electric power only, the starter load shall not be entered in this column. 3.5.4.2.5 - Taxi. Taxi is that condition from the aircraft
41、s first move- ment under its own power to the start of the takeoff run, and from completion of landing rollout .to engine shutdown. 3.5.4.2.6 Takeoff and climb. Takeoff and climb is that condition com- mencing with the takeoff run and ending with the aircraft leveled-off and set for cruising. 3.5.4.
42、2.7 Cruise. Cruise is that condition during which the aircraft is in level flight but is not in. a combat-ready condition. 3.5.4.2.8 Cruise-combat. Cruise-combat is that condition during which the aircraft is performing its combat missions in a combat-ready or actual combat condition. 3.5.4.2.9 Land
43、ing. Landing is that condition between entering into the base leg of a landing approach and completion of rollout. 9 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-3.5.4.2.10 Emergency. Emergency is any period of flight during which the normal sourc
44、es of power are inoperative. During this period, loads essential to safety of flight under any flight condition are transferred to an alternate source of power. These loads are listed in the emergency column, and the total load require- ments are analyzed with respect to the alternate power source.
45、Possible categories of essential electric loads are flight instruments, surface controls, engine controls, and fuel boost systems. If the emergency power source is a battery, see 3.5.5.1. Exception: For rotary wing aircraft having at least two separate primary sources driven by the rotor transmissio
46、n and at least two secondary sources, where a single primary or secondary source can supply all essentid loadss the emergency condi- tion shall be omitted and replaced by analyses of the loads and source capacities remaining after a single failure for each type of power source. 3.5.4.2.11 Mission co
47、mpletion. Mission completion power is defined as minimum electric power required to enable an aircraft to complete its mission. The requirement for this power may occur during any period of the flight. For a multi- engine aircraft the load shall be compared to the power source capacity remaining aft
48、er loss of any one generating or conversion system. For a multi-roleaircraft, the mission requiring most electric power shall be chosen for analysis. 3.5.4.2.12 Additional columns. Additional columns may be used as re- quired to report special operating conditions which may materially affect the loa
49、d analysis by indicating conditions more critical than those specified. These condi- tions might include any of the following: Ground Alert Equipment Warmup Idle Descent Hovering Loiter Jato or Rocket Ignition Launch 3.5.4.2.13 Combination of columns. Where load requirements for one operating condition as specified under 3.5.4.2.12 are identical to those of one or more other conditions, they may be combined into a single column with a suitabl
