Aircraft Limitations

• Maximum takeoff and landing tailwind component is 15 knots.
• Maximum operating altitude is 43,100 feet pressure altitude.
• Maximum takeoff and landing altitude is 8,400 feet pressure altitude.

Flight Maneuvering Load Acceleration Limits:

• Flaps Up: +2.5g to –1.0g

• Flaps Down: +2.0g to 0.0g

• The maximum altitude for flaps out is 20,000ft.

Severe Turbulent Air Penetration Speed:

• 270 knots below 25,000 feet.

• At or above 25,000 feet: 280 knots or 0.82 Mach, whichever is lower.

• Prior to takeoff, the maximum allowable difference between the Captain’s or First Officer’s altitude display and field elevation is 75 feet.

Crosswind Limits for Takeoff:

• On DRY or WET (not including slippery when wet) runways, crew must refer to tables when crosswinds exceed 20 knots.
• On CONTAMINATED runways, crew must refer to tables when crosswinds exceed 10 knots.

Crosswind Limits for Landing:

• On DRY or WET runways: 38 knots

• On CONTAMINATED runways: 15 knots (crew shall refer to the tables below)

• MACTOW LIMITS: 7.5% to 44%

Cabin Pressurization:

• Maximum differential pressure (relief valves): 9.1 psi

• Maximum allowable cabin pressure differential for takeoff and landing: 0.11 psi

• The autopilot must not be engaged below a minimum engage altitude of 200 feet AGL after takeoff.

• Without LAND 2 or LAND 3 annunciated, the autopilot must be disengaged below 200 feet AGL.

• Do not select FLCH mode during takeoff climbout with an engine failed until flaps are up and speed is VREF30 + 80 or greater.

Approach Categories:

• Cat 1: DH 200ft or more, with or without flight director, LAND 2 or LAND 3, Single, dual or triple channel automatic approach and manual landing
• Cat 2: DH below 200 feet but not less than 100 feet, LAND 2 or LAND 3, Dual or triple channel automatic approach and landing (or manual landing)
• CAT 3A: DH below 100 feet but not less than 50 feet, Dual or triple channel automatic approach and landing LAND 2 or LAND 3
• CAT 3B: DH below 50 feet - no DH, Triple channel automatic approach and landing LAND 3

Automatic Landing Maximum Wind Component Speeds:

• Headwind: 25 knots

• Tailwind: 15 knots

• Crosswind: 25 knots (applicable to actual LVO on a non-contaminated runway)

• Maximum glideslope angle: 3.25 degrees.

• Minimum glideslope angle: 2.5 degrees.

• Do not use FLCH on final approach below 1,000 feet AFE.

• The maximum fuel temperature is 49°C.

Engine EGT Limits in 300:

• Starting: 700
• Takeoff: 920
• Max continuous: 850

Engine EGT Limits in ER:

• Starting: 750

• Below 17,000ft: 1095

• All alts: 1050

• In the -300, after a rejected takeoff (RTO) is performed where the thrust reversers were deployed, takeoff is prohibited until maintenance action is complete.

• In the ER, Commanders shall contact Maintenance Control to determine whether maintenance inspection is required before subsequent takeoff is permitted.

APU Starter Motor Duty Cycle:

• 3 start attempts in a 60-minute period (for both electric starter motor and air turbine starter).
• Fuel density must be between 0.7309 and 0.8507 kg/litre.

Minimum Crew Oxygen Pressure Departing from HKG:

• -300: 1500 psi

• -ER: 1000 psi

• The maximum demonstrated takeoff and landing crosswind is 38 knots, including gusts.

• During oxygen drop test verify that the crew oxygen pressure does not decrease more than 50 PSIG

• The ground handling personnel can be recalled to the aircraft by flashing the turnoff or taxi lights twice.

• If there is no oil pressure indication after the EGT increases, do the ABORTED ENGINE START checklist.

• Engine Start is complete and engine is stable when the red EGT start limit line is no longer displayed.

-300 Engine Warm-Up Recommendations:

• If engines have been shut down more than 1.5 hours: run the engines for at least 5 minutes.
• If engines have been shut down 1.5 hours or less: run the engines for at least 3 minutes.
• If the cleared departure route requires an alternative roll mode (e.g. HDG/TRK SEL):TOGA should be used as the roll mode for takeoff and initial climb; select the desired roll mode at or above 400ft AAL.
