Introductory flights are a new EASA provision designed to allow people to be taken on air experience tours in light aircraft
Of course you can call this an air experience flight, you can call it anything you like! What it is, is air experience!
What it isnt is a stepping stone from Ex 1-3 to Exercise 4 because its not an air exercise being taught by a qualified flying instructor. Thats the theory of course, many instructors have little idea of how to teach Exercise 1 -3, especialy those that call it a Trial Flying Lesson!
You dont need to teach someone to recognise if they are going to like flying, they do that by themselves. You do need to teach someone, the datum attiude, the three primary controls and there movement and a simple introduction to the cockpit together with a safety briefing. Oh and if your Beagle you may need to tell them how to use the speaking tube too!
