• Incorporate a FWT into airport design documents Process was initiated in 2013; approval is expected as early as Nov 2016 for

ICAO Annex 14, TBD for FAA AC 150/5300-13A

• ICAO AC 305: elevated to standard (new PANS-Aerodromes) ICAO Aerodrome Panel and Air Navigation Commission to elevate current

advisory document (Circular 305) for accommodating large aircraft fromadvisory document (Circular 305) for accommodating large aircraft from advisory to a Standard - expected Nov 2015

• FAA AC 150/5300-13A (Change 1): Runway to Taxiway Separation On approach, ADG-V runway to taxiway separation could be applied to the

777X Folding Wing Tip Comparison to 777-200 “Folding Wing”

• 777X tip fold– Enables 235.4 ft (71.8 m) span performance

11.4 ft (3.5 m)

– Maintains 212.8 ft (64.8 m) (Code E) span at

taxiways and gates

– Lighter weight

22.5 ft (6.9 m)

– Fewer moving parts

The Boeing Airport Compatibility team will work with the airports to develop operational procedures for the rare FWT failure

777X - Summary

• A FWT provides the best performance solution while maximizing airport compatibility

• FWT reliability / maintainability is consistent with other major systems that may disrupt airport operations / capacity

• Boeing continues to seek input from Airports and Regulators during the g p p g gfolding wingtip development, particularly to develop the process to mitigate disruption in the event of a rare FWT failure

• Most airports are confident their existing fillets are sufficient for the p gadditional wheelbase

• Boeing will work with airports as needed on: ground servicing, de-icing, dual runway entrance taxiways higher ICAO RFF category alternatesdual runway entrance taxiways, higher ICAO RFF category, alternates and ETOPS airports, Jet Bridge and Fuel Pit Connectivity, etc.


737 MAX

Boeing’s newest family of single‐aisle airplanes – 737 MAX 7, 737 MAX 8 and 737 MAX 9 – will build on the Next‐Generation 737’s popularity and reliability: 14% reduction in fuel and carbon emissions

50% below CAEP/6 limits for NOx40% smaller community noise footprint

D l t f th 737 MAX i h d l ith fi fi ti f th• Development of the 737 MAX is on schedule with firm configuration of the first airplane achieved in July 2013.

• First flight is scheduled in 2016 with deliveries to customers beginning in 3Q 20173Q 2017.
