In this paper, a challenging control system design problem is considered to mitigate the aircraft safety threat posted by elevator jam anywhere within the feasible level flight trim region. A new fixed linear servomechanism-based tracking controller with a nonlinear parameter adaptation was designed to achieve stability, maintain a level flight, and perform accurate altitude tracking for an impaired GTM aircraft with elevator jam failure at any position within the feasible trim region.
