Aeronautical Design Standard, United States Army Aviation and Missile Command - Handling Qualities Requirements for Military Rotorcraft

This specification contains the requirements for the flying and ground handling qualities of rotorcraft. It is
intended that the specification should cover land based rotorcraft which have primary missions ranging
from scout and attack to utility and cargo. Additional requirements or modified standards may be required
for rotorcraft that have to operate from small ships in sea states resulting in more than small ship motion.

The requirements of this specification are intended to assure that no limitations on flight safety or on the
capability to perform intended missions will result from deficiencies in flying qualities. Flying qualities for
the rotorcraft shall be in accordance with the provisions of this specification unless specific deviations are
authorized by the Government. Additional or alternate special requirements may be specified by the
procuring activity. For example, if the form of a requirement should not fit a particular vehicle
configuration or control mechanization, the Government may, at its discretion, agree to a modified
requirement that Will maintain an equivalent degree of acceptability.

The following specifications, standards, and handbooks form a part of this document to the extent specified
herein. Unless otherwise specified, the issues of these documents are those listed in the Department of
Defense Index of specifications and Standards (DoDlSS) and supplement thereto, cited in the solicitation.

The system specification will define the operational missions and will specify the Mission-Task-Elements to
be considered by the contractor in designing the rotorcraft to meet the requirements of this specification.
These Mission-Task-Elements will represent the entire spectrum of intended operational usage and will in
most cases be selected from those listed in Table 1.

Many of the quantitative criteria have multiple boundaries that discriminate between rotorcraft that have to
maneuver precisely and aggressively and those that can accomplish their mission tasks with limited agility
and maneuverability. Table 1 indicates which limit shall be met by associating a required agility with the
intended MTEs. If no criterion is provided for the required agility, the next available lower value shall
apply.
