Operational guidelines were developed for member airportsMembers include German and French CAA, European airports, airlines, ACI, IATA, and BoeingExpect other CAAs to joinTwo meetings completed – March 2007, October 2007
Operational guidelines finalized and circulated for approval
Unless otherwise indicated, the requirements are applicable to all types of taxiways.A14 P3.9
Minimum clearance between outer main wheel and taxiway edge: 4.5m for both E and F[RP] A14 P3.9.3
Width of straight portion:- 23m for code letter E- 25m for code letter F[RP] A14 P3.9.5
Taxiway width = 2 x clearance distance from wheel to pavement edge + max wheel track
Code letter E: 23m = 2x4.5m+14m
Code letter F: 25m = 2x4.5m+16m
ADM pt2 p1.2.7+ table 1-1
Origin of the 4.5m clearance distance unknown
Minimum taxiway width of 23 meters (equal to Code letter E requirements)
Wheel-to-edge minimum clearance of 4.5m for Code letter E and F aircraft
Outer wheel span of 12.7m results in outer tire edge to pavement edge (for 23m taxiway) compliant with the ICAO requirement of 4.5m clearance
Various taxiway deviation studies conducted to date show that 4.5m clearance is adequate for safe taxiing

ICAO justification materialInformation and formula describing the SARPS
Justification materialInformation used to justify the proposed guidelines for the 747-8 operations
BACG AgreementProposal for 747-8 operations – Application of ICAO requirements to the 747-8 for infrastructure and operations that currently do not meet the Code Letter F specifications
U.S. Airports Operational Plan747-8 is accommodated through Modification of Standard (MOS) process
Deviation from FAA Group VI standardsAirplane specific / airport specific
First 747-8 MOS meeting held in April 2008 in Washington DCFAA process/expectations describedAttended by 17 U.S. and Canadian airportsSecond meeting planned for 6 October 2008
45m wide runway operational approvalContinuing discussions with FAA to finalize the test plan
Engineering BriefsEB73 - Use of Group V (Code E) taxiway width approved for 747-8EB74 - Group VI runway width currently specified pending 45m (150’) wide runway approvalEB77 (draft) - Taxiway edge margin of 15 ft for Group VI airplanesEB78 (draft) - Taxiway separation criteria based on specific airplane wing span
A group comprising FAA, EASA, JAA, EUROCONTROL, and Boeing was formed in 2007 to recommend the wake vortex separation and associated safety requirements for the 747-8
Team structure (Steering Group / Working Group), membership and process is similar to that used for the A380
747-8 is 747-400 with minor dimensional changes− Small wingspan increase of 3.5m (11.4 ft)− Outer main gear wheel span of 12.7m (41.7 ft) remains in Code D/E− Outer engine span remains same as 747-400 and blast contours
compatible with Code E (Group V) rwy and twy shoulder widths
747-8 can be accommodated at ICAO Code E / FAA Group V airports with minimum disruptions or modifications
Recent history of successful implementation of operational guidelines− Many years of safe 747-400 operations in Europe with ICAO Europe
(AOPG Document 7754) guidelines of reduced clearance taxiing
