V2 gives stall margin for 15° + 15° overbank V2 + 15 gives stall margin for 30° + 15° overbank select LVL CHG and MAX CONT after flaps up

Max Altitude is the minimum of  certified altitude, thrust capability to climb or buffet margin limited altiude ( 0.3 g / 40° bank ) Provides +/- 1.5 load factor ( 48° bank ) 2000 ft above allows +/- 45° bank prior buffet 2000 ft above / below optimum increase fuel by 1 / 2 % 4000 ft below optimum increase fuel by 3 / 5 % Optimum calculation altitude: altitude: Distance + ½ distance 8000 ft below optimum increase fuel by 8 / 14 % provides fuel mileage 1 % less than Max Range M .01 above LRC increase fuel by 1 / 2 % M .74 gives LRC within 2000 ft of optimum LRC provides best buffet margin at all cruise altitude 4000 ft climb needs 135 to 225 kgs but climb only if you cruise 20 min or more rate of cooling is 3°C per hour up to 12 °C Increase of M .01 increase TAT by 0.5 to 0.7 °C

Approach Engine Failure On Final  Flaps 15 Landing All Eng 

retract flaps to 15° and increase Vref by 15 kts Use Flaps 1 for go-around Rudder authority and rudder pedal steering are not affected by rudder trim

Landing Braking with A/S Braking without A/S Reverse thrust with X wind   X wind landing  landing 

Overweight Landing 

 Apply full braking braking  Apply progressive progressive constant constant braking  Avoid reverse reverse trust if A/C in crab crab Reduce X wind wind by 5 knots if assymetric reverse reverse zero crab landing not recommanded if x wind exceeds 17 kts or 23 with flaps 40° Use Flap 30° for speed margin Landing distance is less than TO distance Except on Wet/Contaminated RWY ( check PI ) Reduce Weight by increasing drag Brake Energy Limits not exceeded for F 30° or F40° You can go to speed 20 kts below Maneuvring Speed with normal bank. No 15° protection overbank No Autoland recommanded

Maneuvers Rapid Descent

1° Lights, 2° Start Switches, 3° Altitude, 4° LVL CHG, 5° Thrust Levers and 6° Speed Brake Check MSA, ATC, QNH Fup: 160, F 5°: 135, F 15°: 118, F 30°: 108 Fup: 180, F5°: 145, F15°: 125, F30°: 116 Rem: Fup and F 5° is for MTOW, others for MLW

Use F40°, Reduce Fuel and pitch +/- 10° for touch Use TO EGT Limit for restart Reduce Power, Speed and Altitude Fly manually on Final, Use A/B and full Reverse Vref gives protection for 15° + 15° Overbank Config Wanrning can occur if gear up and F>15° No Assymetry Protection and Slower Speed Override with big constant force to keep control No breakthrough system like the 146 Force on stabiliser trim wheel Full control by elevator still available Limit is for structural life not for controlability Smooth handling in pitch and roll Leave wings pumps on even with low pressure light Gear and leading edge devices cannot retract Extend and retract trailing edge flaps electrically Plan a long final, smooth thrust reduction on flare Use if gear transfer valve stuck and if time  Advise ATC to check check the rwy and and land normally normally Go to your destination if rwy long enough Don't use the autobrake, use max reverse Do not recycle the lever. Don't waiste time  Ask fire truck to check check your gear gear condition Do not arm the speedbrakes Shutdown fuel pumps and critical engine on flare Do not pressurize tha A/C Risk in late go-around if you refuse the touchdown With both window 1 damaged, do an autoland may be open at or below holding speed calm air area over the open window

Low Visibility Procedure Low Vis Take Off 

Visibility less than 400m Check Airport Minimas


Visibility down to 200m Captain make a good briefing

Verify A/C status Verify airport status Verify weather   Verify crew qualification

Bleeds of off or or un unpressurized TO TO Use another rwy Take headwind into account Use improve climb Improve climb + bleeds off  

 At TO thrust, each each 3T below below the max climb weight, you increase increase your climb gradient by 1% Both engine running: climb gradient multiplied by 4: 2,4% x 4 = 9,6%
