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.

Very simple and really useful app for Pilots of any experience

What a really great little app!
Whether overhead joins are stipulated, or downwind or crosswind joins are the name of the game, this app takes all the mental gymnastics out of getting the right approach set up during a high workload phase of the flight.
Once you have entered the type of join, the runway in use, the direction of the circuit and the direction from which you are arriving, a very clear picture is presented showing the optimal point to join the traffic and the heading for each leg of the circuit, with a small red moving arrow "flying" around it.
A genuinely useful and easy to use app which, at the least, could save you embarrassment and could just avoid something much worse.

Incredibly good

This aviation app from AviationLogic truly does serve an excellent purpose while flying; this shows the correct way of joining circuits after easily inputting the certain variables, such as track and dead side location. Once the variables have been set you're given a visual of your approach track and how to join; this minimising the risk of incorrect joins and potential airproxes. I'd definitely recommend purchasing this app to further the safety in aviation; the simple and clear design is a pleasure to use under pressure and will help you to fly the correct approach every time.

Genius little app :)

Brilliantly designed app which is really quick and simple to use. Makes circuits so much easier to visualise and the cockpit a much less stressful place to be.

Would be a really useful tool for pilots of any experience level but especially handy for student pilots or those who simply dread approaching an unfamiliar airfield.
