The A319/320/321 Landing Distance Calculator by Waterline Software offers basic landing distance calculations but faces criticism for lacking features like failure analysis, metric conversion issues, and stability problems.

This is a professional-grade metric calculator designed to estimate the in-flight landing distance for Airbus A319, A320, and A321 aircraft powered by IAE and CFM series engines. Users are advised to thoroughly review the following description prior to purchase to ensure suitability.

The calculator utilizes reference distances applicable to standard modification state aircraft. Should your aircraft differ from this standard configuration, this product may not provide accurate results. Careful verification of the provided information is recommended before proceeding with a purchase.

Intended to handle over 99% of routine pilot calculations for determining F3 and Flap Full landing distances on runways classified as 'Dry' or with 'Good' braking conditions, this tool considers factors such as:

Dry or Good Braking Action
Flap settings: Flap 3 and Flap Full
Autobrake settings: Low, Medium, & Max (Manual)
Altitude: from ISA to ISA+20
Elevation: Sea level to 9,000 feet
Reverser usage: none, one, or two reversers
Runway downhill slope: 0% to 3%
Speed variations from VLS to VLS+15 knots
Wind component: tailwinds from 0 to 15 knots
Safety margins: 0%, 5%, 10%, 15%, or 20%
Landing types: autoland and overweight landings

The calculator references standard distances based on aircraft model and engine type, including:

A319-IAE, Dry, Flap Full, Max Manual Brakes at 63.0T = 1000 meters
A320-IAE, Dry, Flap Full, Max Manual Brakes at 66.0T = 1080 meters
A321-IAE, Dry, Flap Full, Max Manual Brakes at 78.0T = 1200 meters
A319-CFM56-B5, Dry, Flap Full, Max Manual Brakes at 63.0T = 1030 meters
A320-CFM56, Dry, Flap Full, Max Manual Brakes at 66.0T = 1090 meters
A321-CFM56, Dry, Flap Full, Max Manual Brakes at 78.0T = 1220 meters

While the calculator aims to provide accurate estimates, the Flight Operations Handbook (QRH) remains the definitive resource for calculating landing distances. Users should verify that the results generated align with operational standards and requirements.

Pros

Specialized calculator for Airbus A319/320/321 landing distances, which can be very useful for pilots and aviation professionals.
Available on iOS devices, making it portable and accessible for users in the aircraft or on the go.
Supports family sharing, allowing multiple users within the same family to access the app without additional purchase.

Cons

The app has a very limited range of units, primarily supporting metric measurements. This reduces its utility for users in regions like the US where imperial units are standard.
User reviews indicate that the app crashes frequently and does not support failures in landing distance calculations, which is a significant limitation for realistic flight planning.
The app's pricing is low, but reviews suggest it does not offer enough value, especially considering its limitations and bugs.
Limited to iOS devices, so Android or other platform users cannot access this software.
Lack of detailed support or troubleshooting options beyond basic contact methods.
