So, here's another thought regarding sequence development: The idea behind the progressive class structure in both IMAC and IAC is in part to actively assist pilot's develop a certain skill set in one class that is a fundamental component of the proceeding class. For example, sportsman pilots are introduced to hesitation rolls on the quarters (4 pt roll), for pilots in intermediate and above these roll elements are ingrained (or should be) and don't require a large amount of cognitive thought to complete. In other words, where as a sportsman pilot is actively thinking, reacting, and learning through the point roll process, an intermediate or advanced pilot has this "programmed" to be an automatic or inherent action. With respect to sequence development, would it not be helpful to pilots to reflect this skill development process in the sequences themselves? By that I mean that, to a certain degree, all the classes could share a common base figure sequence. Obviously, with Int - Unl there have to be some variations to accommodate rollers (though there is no rule that says we have to have rollers...) but for the most part the base figures could all be the same (or very similar) with differing roll elements. This would establish a degree of continuity and commonality from Basic to Unlimited, and highlight the skill development required as one moves from class to class. Anyone?
