1000’/500 AFE

  • On correct lateral path (+/- one dot for ILS/LOC, 0.30NM cross track for RNAV, or 1/2 dot for VOR)
  • On the correct vertical path (Glidepath, +/- one dot)
  • In the final landing configuration (Landing gear and flaps extended, speed brakes retracted)
  • Absent any GPWS Warnings and Cautions
  • Landing Checklist completed

500’ AFE

  • Steady rate of decent not to exceed 1000’ / min
  • Within -5/+15 knots of target speed for approach
  • Thrust stabilized, usually above idle, commensurate with what is required to maintain target speed criteria.

Furthermore, to minimize the chances of a go-around, if the weather is reported to be below 1/2 mile or 2400 RVR AND all of the requirements for an autoland can be met, it is Frontier‘s policy to brief it and fly it as a Cat II / Cat III autoland.

Q

AIRCRAFT SYSTEMS LIMITATIONS

Autoland parameters — Engine out

Can we conduct an autoland with one engine inop?

A

The Airbus A320 series aircraft are approved by the AFM to perform single engine autoland approaches. Although Frontier Airlines’ limitations prohibit the initiation of single engine autoland approaches, the flight crew may use emergency authority if it is determined to be the safest course of action. NOTE: On A320 aircraft with an engine inoperative, single engine autoland approaches are only approved by the AFM in CONFIG FULL.
