Engineering Brief No. 65A

shoulders are followed, and procedures are implemented for the full length of the
runway to be inspected for foreign object debris after takeoff prior to successive
aircraft operations.
The significance of this requirement is that Flight Standard Service recognizes that airport
operators require time to adequately plan for and construct wider stabilized shoulders. Until
their completion, pilots will follow specific operational procedures and airport operators will
inspect the full runway length after each A380 takeoff for the presence of foreign object
debris prior to ensuing aircraft operations.
In summary, runways receiving A380 service must be operated in accordance with one of the
above requirements. For either option the airport operator is required to designate the
runway(s) that will accommodate A380 operations in the airport’s A380 Operational Plan.
No modification-to-standard (MoS) is required for either case. However, to receive AIP
Federal funding or PFC authority for widening stabilized shoulders to 50 feet (15 m), a MoS
needs to be filed for approval.
B. PURPOSE
This engineering brief provides airport operators and FAA Airports Regional Offices guidance
when airports operators must file a MoS and construction options to address the requirements in
paragraph A. New runway construction or major reconstruction, including runway blast pads,
that receives Federal funding under the Airport Improvement Program (AIP) or is approved for
the use of Passenger Facility Charges (PFC) is subject to Airplane Design Group VI design
standards, as specified in Advisory Circular (AC) 150/5300-13, Airport Design. In the case of
new runway construction or major reconstruction not receiving AIP Federal funding or PFC
authority, it is highly recommended that such construction comply with Airplane Design Group
VI standards.
Airports Regional Division Managers have the authorization of approving MoSs that meet the
conditions of this engineering brief. Issuance of a MoS requires a copy be sent to the Airport
Engineering Division, AAS-100.
C. CANCELLATION
Engineering Brief No. 65, Minimum Requirements to Widen Existing 150-Foot Wide Runways
for Airbus A380 Operations, dated February 13, 2004 is cancelled. The cancellation of EB 65
withdraws the design option for converting existing stabilized shoulders to runway pavement.
D. Filing of a MOS and Construction Options
(1) Existing 150-foot (45-m) wide runways having 35-foot (10.5-m) wide stabilized
shoulders. Such runways must be operated in accordance with one of the above requirements
from paragraph A. To avoid the full-length runway inspection for the presence of FOD after
each A380 takeoff, a 150-foot (45-m) runway must have at least 50-foot (15-m) stabilized
shoulders. For either option the airport operator is required to designate the runway(s) that will

accommodate A380 operations in the airport’s A380 Operational Plan. Existing runway surface
markings, signage along the runway, and lighting fixtures are not required to be changed. This
subparagraph does not require filing of a MoS except for airport operators desiring to receive AIP
Federal funding or PFC authority for widening stabilized shoulders to 50 feet.
(2) Existing 200-foot wide runway with less than a 250-foot (76-m) overall width. Such
runways must be operated in accordance with one of the above requirements from paragraph A.
To avoid the full-length runway inspection for the presence of foreign object debris after each
A380 takeoff, a 200-foot (60-m) runway must have at least 25-foot (7.6-m) stabilized shoulders.
For either option the airport operator is required to designate the runway(s) that will
accommodate A380 operations in the airport’s A380 Operational Plan. Existing runway surface
markings, signage along the runway, and lighting fixtures are not required to be changed. This
configuration does not require filing of a MoS. It is recommended that widened shoulders
provide the Airplane Design Group VI design standard of an overall total width of 280 feet (85
m).
(3) New Runway Construction or Reconstruction of 150-foot (45-m) Wide Runways.
New runway construction or major reconstruction, including runway blast pads, that receives AIP
Federal funding or PFC authority is subject to Airplane Design Group VI design standards
including the requirements for runway and stabilized shoulder widths, having an overall total
width of 280 feet (85 m), as specified in AC 150/5300-13 and construction in accordance with AC
150/5320-6, Airport Pavement Design and Evaluation. The cancellation of EB 65 withdraws the
