Into The Blue say:

The idea of this session is to show you just what these pilots do day in, day out in their 'flying office' at the sharp end of the aircraft. After being introduced to your Captain (all pilots have hours and hours of commercial airline experience), you will be shown round the flight deck and invited to sit in the very best seat in the house - the jump seat. This is the fold-down seat just inside the cockpit and it allows you to see just what the pilots are doing - and this is where the unravelling of your irrational fear of flying begins. Your Captain will run through all the procedures that are carried out, explaining what they are doing as they go along and the rigorous safety steps and checks at each stage of the flight. By understanding what the crew does, as you 'fly' from Gatwick to Belfast International, you start to eliminate the nervousness. As each fear of flying course is tailored completely to you, you can cure that fear of turbulence with rational explanations, hear what happens when the flight is in a holding stack, or whatever else about flying that makes you apprehensive. You can even ask all the questions you've wanted to ask but always been afraid to.
