DRIFTDOWN PROCEDURE

A
  • Set maximum continuous thrust
  • Refer to the speed cards for driftdown performance speed (When unable to hold altitude, decelerate to VENR)
  • Use ice protection equipment only when necessary
  • Proceed to the nearest suitable airport for landing. When unsure of terrain clearance, divert to the driftdown airport listed on the flight release using Method 1 or 2 procedures as appropriate.
  • Refer to the AeroData Performance Handbook for additional information.
