This paper details a method to ascertain the reachability
of known emergency landing sites for any fixed wing
aircraft in a forced landing due to engine failure in steady
uniform wind conditions. With knowledge of the aircraft’s
state and parameters, and landing site location and landing
direction, the minimum height loss path can be defined. This
uses glide performance calculations and a trajectory planner to
give a minimum height loss to each landing site. Based on the
aircraft’s initial altitude it can calculate if the site is reachable,
and how reachable it is. The path definition takes into account
wind and uses a geometric shape called a trochoid to define
the gliding turns in wind. This method is generic enough for
use by any aircraft in any wind conditions.
