    Operating Performance:

  • Mmo 0.85 Mach Max. Operating Speed

  • Mne 0.92 Mach Never Exceed Speed

  • Vno knots Max. Operating Speed IAS

  • Vne365 knotsNever Exceed Speed IAS

  • Vat150 - 156 knotsLanding @ Runway Threshold Speed @ MLW full flap/Gear down

  • Take-off speed@ MTOW with Flap 3 is 155 - 160 kts, otherwise 155kts @ flap 2

  • ILS & Approach speed 180 - 150 kts @ Flap2 (Kyb 2)

  • DO NOT Exceed 250kts @ or Below 10,000ft Altitude.*

Take-off speed@ MTOW:

  • V1 145-148kts @ flap2/3 (V1 is the go or no-go decision speed)
  • VR 155-160kts (VR is the rotation speed ie lift-off speed)
  • V2 180kts (V2 is the safe climb-out speed)
    ILS & Approach speed @ MLW:
  • 185 kts Flap2 (Kyb 2) to full flap/gear down @ Vat 150 - 155 kts
  • Vat = 1.30 Vso (Vso is stall speed @ full flap/gear down)
    Cruise Speeds:
  • Cruise Speed 490 KTAS
  • Cruise Altitude 28,000 - 35,000ft depending on weight.
  • Typical Cruise Speed is 0.80 - 0.85 Mach @ FL280 - FL350
  • Long Range Cruise speed is 496 KTAS @ FL350 (35,000ft)
  • Max. cruising speed is 507 KTAS

Field Lengths

  • Take-off 10,561 ft

  • Landing 7,870ft
    Take-off Check List

  • Allowable Take-off Weight (MTOW or lower)

  • Flaps Set

  • Trim Set

  • Autopilot Controls Off
    Final Landing Check List

  • Gear Down/Green

  • Flaps/Slats Set/ 3 or 4

  • Speed BrakesArmed

  • ILS ferq/Glide Slope Tuned-in
    During Descent Check

  • Check Allowable Landing Weight (MLW 575,000 lb. or lower)

  • Review your ILS approach & Runway heading
    ROC Rate Of Climb
    Below 10,000 ft

  • max.3800 fpm @ 250 kts

  • DO NOT Exceed 250kts @ or Below 10,000ft Altitude.*

Above 10,000 ft to Cruise Flight Level FL

  • 2200fpm from 10,000 - 20,000ft @ 280 - 340kts
  • 2000 - 1500fpm from 20,000 - 26,000ft
  • 1500 - 400fpm from 26,000 - 35,000 ft depending on weight
    ROD Rate Of Descent
  • From Cruise FL to 10,000ft hold 0.79 Mach until 290 kts, reduce thrust for 2500 fpm
  • Below 10,000ft rate of descent varies with ATC requirements, but is between 800 - 3000fpm
  • In normal conditions 250kts idle descent , then slow & configure speed so as to not add power until on Glide Slope.
  • Use speedbrakes to slow down
  • Glide Slope descend is between 1500 - 500fpm depending on your situation
  • At Runway Threshold descend between 400-200fpm for a smooth touchdown landing
