EMPLOT plots the energy–maneuverability (E–M) characteristics of aircraft for simultaneous comparison of capabilities during sustained maneuvers.
Inputs include a structure array of aircraft properties for any number of aircraft, density altitude, and plot parameters.

Outputs may include the figure handle, a structure of common handles, and a structure array of aircraft-specific handles for command-line plot manipulation.

Furthermore, the function returns AS for maximum turn rate (i.e. maneuvering speed), AS for maximum sustainable turn rate, and AS for maximum sustainable load factor for each aircraft evaluated.

Note: Aerospace Toolbox is used only for lookups in the International Standard Atmosphere (atmosisa).
