Boeing 747-8 Wake Category
ICAOs Air Navigation Commission reviewed and approved a Safety Assessment presented by the Boeing 747-8 Wake Vortex Steering Group. The Safety Assessment is endorsed by the FAA, Eurocontrol, EASA and the Boeing Company.
The Steering group determined that Flight-test data measured with LIDAR shows the 747-8 wake strength to be less than or equal to the 747-400 as the comparison aircraft, at distances of interest. The Boeing 747-8 configuration is designed with higher inboard wing loading compared to 747-400,
ICAO has accepted the recommendations of the B747-8 Wake Team that examined flight test and simulation data to establish the Safety Case. Approach, landing, departure, climb/descent, and cruise operations of the B747-8 relative to other aircraft were considered.
The safety case supports the assertion that the Boeing 747-8 is safely categorized as Heavy and all standard separation minima as specified in ICAO Doc. 4444 PANS ATM for Heavy aircraft should be applied.
The first 747-8 freighter will be delivered to Cargolux on 19 September, and the first 747-8 passenger version is expected to be delivered following completion of flight trials in December 2011.
