and maximum reverse
thrust is selected at landing.
LDG CONF / APPR SPD / LDG DIST COMPUTATION FOR A SINGLE
FAILURE
Determine the FLAPS lever position for landing to be selected
Compute the VAPP: VAPP = VREF + Δ VREF + APPR COR
‐ Determine the Δ VREF
‐ Determine the APPRoach CORrection (Refer to ABN-80 VAPP CALCULATION)
Compute the LDG DIST:
‐ Determine the LDG DIST factor. Multiply it by the additional factor, if any (Refer
to ABN-80 VAPP
CALCULATION)
‐ Multiply the obtained LDG DIST factor by the ACTUAL LANDING DISTANCE
WITHOUT AUTOBRAKE
– CONFIGURATION FULL – without reversers correction (Refer to FPE-IFL
Landing Distance Without
AUTOBRAKE - CONF FULL)
LDG CONF / APPR SPD / LDG DIST COMPUTATION FOR MULTIPLE
FAILURES
Only combine PRIMARY or SINGLE failures
Determine the Flaps lever position for landing to be selected:
‐ Use the lowest Flaps Lever Position for landing(i.e. if FULL and 3, use 3)
Compute the VAPP: VAPP = VREF + Δ VREF + APPR COR
‐ Use the highest Δ VREF to compute VAPP
‐ Determine the APPRoach CORrection (Refer to ABN-80 VAPP CALCULATION)
Compute the LDG DIST:
‐ Determine the applicable LDG DIST factors in the same column (“WITH REV.”
or “WITHOUT REV.”)
‐ Multiply the applicable LDG DIST factors together, unless all values are marked
with an asterisk (*). If
all values are marked with an asterisk, use the highest LDG DIST factor. Multiply it
by the additional
factor, if any (Refer to ABN-80 VAPP CALCULATION)
‐ Multiply the obtained LDG DIST factor by the ACTUAL LANDING DISTANCE
WITHOUT AUTOBRAKE
– CONFIGURATION FULL – without reversers correction (Refer to FPE-IFL
Landing Distance Without
AUTOBRAKE - CONF FULL)
Examples applicable to Dry runways / A/THR ON / No wind / WITHOUT
