ASTM F2244-13

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F2244 − 10 F2244 − 13
Standard Specification for
Design and Performance Requirements for Powered
1
Parachute Aircraft
This standard is issued under the fixed designation F2244; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 The following requirements apply for the manufacture of powered parachute aircraft. This specification includes design and
performance requirements for powered parachute aircraft.
1.2 This specification applies to powered parachute aircraft seeking civil aviation authority approval, in the form of flight
certificates, flight permits, or other like documentation.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory
requirements prior to use.

3. Terminology
3.1 Definitions:
3.1.1 gross weight, n—total aircraft system weight(s) at takeoff.
3.1.2 maximum takeoff weight, n—gross weight limit as defined by the manufacturer, proven through compliance with this
specification and placarded on the aircraft as the not-to-exceed gross weight.
3.1.3 powered parachute, n—aircraft comprised of a flexible or semi-rigid wing connected to a fuselage in such a way that the
wing is not in position for flight until the aircraft is in motion thatmotion. That aircraft has a fuselage with seats, engine, and wheels
(or floats), such that the wing and engine cannot be flown without the wheels (or floats) and seat(s). Unique to the powered
parachute is the large displacement between the center of lift (high) and the center of gravity (low), which is pendulum effect.
Pendulum effect limits angle of attachattack changes, provides stall resistance and maintains flight stability.
4. Flight
4.1 Performance Requirements:
4.1.1 Proof of Compliance—Each of the following requirements shall be met at the maximum takeoff weight and most critical
center of gravity (CG) position. To the extent that CG adjustment devices may be adjusted for flight, these components will be
evaluated in the least favorable recommended position as it affects either performance or structural strength.
4.1.2 General Performance—All performance requirements apply in and shall be corrected to International Civil Aviation
Organization (ICAO) defined standard atmosphere in still air conditions at sea level. Speeds shall be given in indicated (IAS) and
calibrated (CAS) airspeeds in miles per hour (MPH).

4.1.2.1 Wing Performance—For straight-ahead flight and turns in either direction during climb, cruise, descent, and landing
flare, it shall be shown that the limits of control input are less than the wing stall limitations:

(2) If adjustable wing trim is available, it shall be tested to both the most negative and most positi
