ApproBASE Circuit Pattern Calculator for General Aviation Pilots

By Aviation Logic Limited

This app is only available on the App Store for iOS devices.


AviationLOGIC apps are designed by pilots for pilots.

ApproBASE is the only app currently available to assist General Aviation pilots of all experience levels in planning an approach, join and landing at any UK airfield.

ApproBASE provides a quick and easy, simple and intuitive interface that allows pilots to generate a generic, animated diagram of the runway and circuit layout for any airfield. Stunningly clear animations help illustrate a pilot's join path and headings for each leg of the circuit pattern through to touch down. Whether the pilot wants to use a Standard Overhead Join or join Crosswind, Downwind, on Base or go Straight-In to an airfield with or without a deadside, ApproBASE can handle it! In short, ApproBASE is a powerful tool that has become an essential part of every pilot’s flight bag.

The AviationLOGIC team would like to thank all the instructors, students, authorities and customers that have kindly contributed to the development of ApproBASE. The previous version of ApproBASE was commended with 5 Star reviews and also featured in Apple's "What's Hot" in Navigation category, a true testament to the knowledge and insight provided by everyone involved. The AviationLOGIC team hopes this new and much enhanced version of ApproBASE is as successful as the previous.
