A319/320/321 Landing Dist Calc

A metric calculator to determine in-flight landing distance for the Airbus A319/320/321 IAE & CFM series aircraft. Please read the following description carefully before purchase . This calculator employs reference distances that apply to standard modification state aircraft. If your airframes vary from standard mod-state then this product may be unsuitable for you. Check the information below carefully before purchase.

This calculator will cater for 99%+ of calculations made by the pilot in determining F3 & Flap Full landing distance on runways designated as Dry or Good braking action. This calculator considers:

Dry/Good Braking Action
Flap 3, Flap Full
Autobrake Low, Medium & Max Manual
ISA to ISA+20
Elevation Sea Level to 9000
Downhill runway slope 0 to 3%
VLS to VLS+15kts speed increments
0 to 15kts tailwind
0/5/10/15 or 20% Safety Margin
Autoland & Overweight landings

This calculator uses standard reference distances of:

A319-IAE Dry, Flap Full, Max Manual Brakes at 63.0T = 1000m
A320-IAE Dry, Flap Full, Max Manual Brakes at 66.0T = 1080m
A321-IAE Dry, Flap Full, Max Manual Brakes at 78.0T = 1200m

A319-CFM56-B5 Dry, Flap Full, Max Manual Brakes at 63.0T = 1030m
A319-CFM56-B5 Dry, Flap Full, Max Manual Brakes at 63.0T = 1030m
A320-CFM56 Dry, Flap Full, Max Manual Brakes at 66.0T = 1090m
A321-CFM56 Dry, Flap Full, Max Manual Brakes at 78T = 1220m


As always the QRH remains the definitive guide to calculating landing distances and you should satisfy yourself that the results provided by this software are valid.
