7. Aircraft Systems Operational Limits WEIGHT The gross weights are: 1. Field takeoff..........................................................24,500 pounds 2. Field landing (minimum rate of descent)..............16,000 pounds 3. Field landing (non flared and field arrestments)...14,500 pounds Note: Field landings at gross weights in excess of maximum recommended weights should be attempted only in an emergency; refer to the Flight Manual for more on Landing at High Gross Weights.

8. Aircraft Systems Operational Limits AIRSPEED LIMITATIONS

9. Aircraft Systems Operational Limits MANEUVERING FLIGHT/PROHIBITED MANEUVERS 1. Negative-g flight in excess of 10 seconds 2. Intentional spins 3. Aileron rolls: a. That exceed 360 degrees of roll b. That exceed one-half stick deflection with fuel in the external fuel tanks 4. The maximum permissible change in angle of bank during rolling pullouts or rolling pushovers is 180 degrees 5. (TA-4) 90º to 100º nose up zero airspeed.

10. Aircraft Systems Operational Limits ACCEL (G)VS GWT

11. Aircraft Systems Operational Limits ACCELERATION (G) ACELERATION LIMITATIONS Accelerations at which moderate buffeting occurs shall not be exceeded. Otherwise, the maximum permissible accelerations for flight are shown in the Flight manual. As gross weight increases above 12,500 pounds, maximum permissible accelerations decrease as shown in the Flight manual. During conditions of moderate turbulence, avoid deliberate accelerations in excess of those permitted as shown in the Flight manual to minimize the probability of overstressing the aircraft as a result of the combined effects of gust and maneuvering loads. Transonic pitchup can occur during speed reductions in the transonic region. Buffet onset and flight strength limits at low altitude combat conditions are shown in the Flight manual. ****CAUTION**** *To minimize the probability of exceeding the maximum permissible load factor due to the combined effects of maneuvering load factor and transonic pitchup, the following procedure is recommended: 1. Below 15,000 feet, at speeds in excess of 0.94 IMN, avoid deliberate accelerations in excess of +4g. 2. Above 15,000 feet, avoid deliberate accelerations that exceed buffet onset.

15. Aircraft Systems Operational Limits WING PRESSURIZED The below limitations apply at all times that the wing fuel cell is pressurized (Emergency Transfer): 1. No landings 2. Coordinated turns only 3. Aircraft load factor limits of +0.1 to +2.0 4. No air refueling as receiver aircraft 5. No nosedown attitudes 6. 45-degree bank, maximum 7. 400 KIAS maximum

16. Aircraft Systems Operational Limits CROSS WIND LANDINGS THE BELOW ARE MAXIMUM RECOMMENDED 90 DEGREE CROSSWIND COMPONENTS FOR THE INDICATED CONDITION: NORMAL AIRCRAFT: 25 knots NO SPOILERS: 15 knots DISCONNECTED CONTROLS: 8 knots (take arresting gear above) DRAG CHUTE:10 knots

17. Aircraft Systems Operational Limits TIRE AND DRAG CHUTE TIRE LIMIT SPEED A maximum of 175 knots groundspeed is imposed upon the aircraft during ground operations because of structural limits of the tires. DRAG CHUTE LIMITATION A maximum speed of 160 KIAS is imposed upon the aircraft with the F-4 5-ring slot type drag chute deployed. Flight without the drag chute canister is not permitted due to inadequate engine cooling.

18. Aircraft Systems Operational Limits MISCELLANEOUS MISCELLANEOUS LIMITATIONS The external baggage container (EBC) may be carried, loaded or empty, within the limits of flight for full 300-gallon tanks except as modified by the following restrictions. 1. Airspeed limitation is 525 KIAS or Mach 0.80, whichever is lower. 2. Normal acceleration limitations are -1.0 to positive 3.0g’s. 3. Flight controls, propulsion controls, or other systems shall not be moved or operated so as to result in rapid or abrupt aircraft responses. 4. Side slipping or skidding shall be avoided. 5. Angle of bank shall not exceed 60 degrees. 6. Jettison in emergency only, in 1.0g level flight at a maximum of 475 KIAS/0.80 IMN.
