Not sure about the value of the flight but maybe it says something that the RCAF and RAF both evaluate 'potemtial' pilots in a short simulation and without actually letting them near and actual aircraft. As far as I learned from my kids, (four of whom attended 'Selection' the handling part of the process accounted for about twenty minutes in which they were asked to 'fly' a (fixed wing) circuit on instruments three or four times. Being shown their tracks and the miscues being pointed out the assessment was on their 'improvement.'
(Three of them passed and are now helicopter pilots.)
Not saying anything about this actual offer but twenty minutes flight time would rule out a whole host of the wannabes.
