The first step is to make sure you have the 17 views required to track a bandit in combat. I have learned over the years that many people do not map all 17. Many more do not have them map in a fashion that makes views changes easy.
Here is a link to my write up on the subject.
https://home.comcast.net/~micelihouston/lessons/Stage1lessons/lesson1views.htmThe first drill I always recommend is 1 v 1 dueling without shooting. When the fight deteriorates to a low level flat fight separate and go again.
An excellent drill if you can't find a dueling partner is loops through a hangar while keeping the hangar in sight. It is described on the above web page and there is a film showing its execution. However, the film predates the new field layout and the hangar is no longer there. Guess I need to make a replacement film.
The loops through the hangar drill builds several skills at once. View usage, view transition and fine aircraft control while looking other than forward. It is a great drill for any pilot have trouble looking backwards or up while flying a precision path.
