Attachment 1
Advisory
U.S. Department
of Transportation Circular
Federal Aviation
Administration
Subject: Aircraft Boarding Equipment Date: 6/29/2012 AC No: 150/5220-21C
Initiated by: AAS-100 Change:
1. PURPOSE. This advisory circular (AC) contains the Federal Aviation Administration's (FAA's)
performance standards, specifications, and recommendations for the design, manufacture, testing and
maintenance of equipment used in the boarding of airline passengers.
2. CANCELLATION. This AC cancels AC 150/5220-21B, Guide Specification for Devices Used
to Board Airline Passengers with Mobility Impairments, dated March 17, 2000.
3. SCOPE. This AC covers the four most common pieces of equipment used to board aircraft:
a. Passenger boarding bridges (PBBs) that are entered from the passenger terminal boarding
area,
b. Ramps that are moved into place to allow boarding from the airport apron,
c. Lifts to vertically transport passengers from the airport apron to the door of the aircraft, and
d. Aircraft boarding chairs used to transfer passengers from their wheelchair or other apparatus
to their seat in the aircraft cabin.
The physical area covered in this AC is that which is bounded by the door of the passenger terminal area,
on one end, to the door of the aircraft, on the other end. Although this AC refers only to aircraft boarding
(enplaning), all references apply equally to disembarking (deplaning) with the described procedures
occurring in reverse order.
Chapters 3-5 for this AC are primarily based on the performance standards, specifications, and
recommendations contained in the Society of Automotive Engineers (SAE) Aerospace Recommended
Practice (ARP) 1247, General Requirements for Aerospace Ground Support Equipment (Motorized and
Non-motorized), U.S. Access Board's Technical Assistance Manual for ADA Accessibility Guidelines
(ADAAG) for Transportation Vehicles (September 1998), and ADA and ABA Accessibility Guidelines
for Buildings and Facilities (Published in the Federal Register July 23, 2004 and amended August 5,
2005). Chapter 6 of this AC is based on the U.S. Access Board Technical Paper on Guidelines for
Aircraft Boarding Chairs. Additional requirements and clarifications have been added where necessary.
The Department of Justice issued 28 CFR Part 36, adopting enforceable accessibility standards under the
ADA consistent with the minimum guidelines and requirements of the United States Architectural and
Transportation Barriers Compliance Board (Access Board). The rule at 28 CFR Part 36 adopts the Access
Board guidelines found at 36 CFR Part 1191, Appendix D (2009), and these guidelines now have legal
effect. Accordingly, all references to 36 CFR Part 1191, Appendix D (2009) throughout this AC, are
codified at 28 CFR Part 36.

AC 150/5220-21C 6/29/2012
Pertinent FAA AC, U.S. Access Board, Military Standards and non-government industry standards are
also referenced (see Appendix C for more information) and, in the event of a conflict between the text of
this document and the references cited herein, the text of this document takes precedence.
In addition to general design guidance, areas that may require clarification or tailoring in purchasing
PBBs, ramps, lift and boarding chairs to suit the needs of specific airports are contained in tables at the
end of each of their respective chapters.
4. APPLICATION. The Federal Aviation Administration recommends the use of the guidance in
this publication for the preparation of specifications for devices to assist in the boarding of passengers
with mobility impairments.
Equipment meeting the specifications provided in this circular satisfies the boarding device requirements
contained in U.S. Department of Transportation regulations 49 CFR Part 27, Nondiscrimination on the
Basis of Disability in Programs or Activities Receiving Federal Financial Assistance, paragraph 27.72,
and 14 CFR Part 382, Nondiscrimination on the Basis of Disability in Air Travel, subpart G - Boarding,
Deplaning, and Connecting Assistance, paragraphs 382.91 through 382.105.
The use of this AC is a means of fulfilling the applicable mandatory requirements set out in Airport
Improvement Program (AIP) grant assurances, Passenger Facility Charge (PFC) assurances, and
regulations; alternate means of satisfying these requirements which are in accordance with applicable
laws and regulations are acceptable.
5. PRINCIPAL CHANGES. The previous version of this AC discussed only the passenger lift
scenario and associated equipment. This document updates that effort while also addressing the other
methods and equipment used to board an aircraft.
6. COMMENTS OR SUGGESTIONS for improvements to this AC should be sent to:

CHAPTER 1. INTRODUCTION
1.1. GENERAL.
A fundamental goal of this AC is to promote the simple, fast, and dignified boarding of all passengers
regardless of their physical, sensory, or cognitive capabilities through the use performance standards,
specifications, and recommendations for aircraft boarding equipment.
NOTE: The Department of Justice issued 28 CFR Part 36, adopting enforceable
accessibility standards under the ADA consistent with the minimum guidelines and
requirements of the Access Board. The rule at 28 CFR Part 36 adopts the Access Board
guidelines found at 36 CFR Part 1191, Appendix D (2009), and these guidelines now have
legal effect. Accordingly, all references to 36 CFR Part 1191, Appendix D (2009)
throughout this AC, are codified at 28 CFR Part 36.
1.2. PERSONS WITH DISABILITIES.
a. The equipment in this advisory circular (AC) provides accommodations for a wide range of
passengers, including those with mobility, sensory, and cognitive impairments. It is important to
recognize that, for each of these types of disabilities, there exists a full range of characteristics. Mobility
impairments range from people that have difficulty walking due to use of a prosthetic to the high level
quadriplegic. Likewise, sensory impairments are on a continuous scale; most people with visual and
hearing impairments are not totally blind or deaf but may have a very limited range of visual or aural
stimuli that they can detect.
b. Understanding that all of the different disabilities include a wide range of severity is essential in
planning equipment that is appropriate for everyone. Many manifestations of a disability must be
considered so as not to leave out certain groups of individuals with mobility impairments. For example,
the typical reference made for "persons with mobility impairments" is that of wheelchair users. But
elderly passengers who walk with a shuffle must also be considered. As such, the importance of
handrails, level surfaces at transitions, and appropriate floor surfaces play a significant role in the overall
equipment design.
NOTE: For purposes of this document, the term "wheelchair" includes any wheeled mobility aid in
which a person sits - typically this includes scooters, manual chairs, and power chairs.
c. Universal Design. "Universal design" is a concept that aims to provide an equal level of service
to persons of all ages and abilities. As applied to the field of aviation, universal design is fundamental to
the safe and efficient transportation of the flying public. In keeping with the concept of universal design,
the overall philosophy of this document is to specify both the performance and design requirements that
enable seamless and integrated transportation options for all passengers.
