HEIGHT - VELOCITY DIAGRAM
The Height - Velocity diagram enable to establish if, in the event of a single
engine failure during takeoff, landing or other operation near the surface, a
combination of airspeed and height above ground exists from which a safe
single engine landing on a smooth, level and hard surface cannot be assured
(dangerous zone).
The height - Velocity diagram is split in two charts.
Chart A shows the weight values, together with outside air temperature and
altitude, at/below which the dangerous zone does not exist. For heavier
weights refer to Chart B.
Chart B defines the combinations of height and airspeed to avoid for safe
operations.
NOTE
The height - velocity diagram does not define the conditions
which assure continued flight following an engine failure nor the
conditions from which a safe power off landing can be made.
