1. Purpose of This Notice. This notice provides interim air traffic procedures applicable to B748
operations. The procedures specified in this notice supplement existing guidance contained in Federal
Aviation Administration (FAA) Order JO 7110.65, Air Traffic Control.
2. Audience. This notice applies to the following Air Traffic Organization (ATO) service units:
En Route and Oceanic, Terminal, and System Operations.
3. Where Can I Find This Notice? This notice is available on the MyFAA employee Web site at
https://employees.faa.gov/tools_resources/orders_notices/ and on the air traffic publications Web site at
http://www.faa.gov/air_traffic/publications/.
4. Explanation of Policy Change. The procedures in this notice establish interim wake turbulence
separation criteria for the B748 aircraft.
5. Procedures. Standard air traffic control procedures contained in FAA Order JO 7110.65 and
facility letters of agreement must be applied in support of the B748 with the following
additions/changes:
a. TERMINAL.
1. Separate aircraft operating directly behind or directly behind and less than 1,000 feet below or
following an aircraft conducting an instrument approach by:
NOTEConsider
parallel runways less than 2,500 feet apart as a single runway because of the possible effects of wake
turbulence.
(a) Heavy behind B748 – 10 miles.
(b) Large behind B748 – 10 miles.
(c) Small behind B748 – 10 miles.
(d) When applying wake turbulence separation criteria for terminal operations that are defined in
minutes, add 1 additional minute.
2. Visual separation rules specified in FAA Order JO 7110.65, Chapter 7, Section 2, Visual
Separation, must not be applied with respect to B748 aircraft.
b. EN ROUTE.
1. Small/large/heavy behind a B748 – 5 miles.
2. Small/large/heavy behind a B748 being handed off/transferred to terminal facilities – 10 miles
when the trailing aircraft crosses the terminal/en route airspace boundary.

3. Visual separation rules specified in FAA Order JO 7110.65, Chapter 7, section 2, Visual
Separation, must not be applied with respect to B748 aircraft.
6. Distribution. This notice is distributed to the following ATO service units: Terminal, En Route
and Oceanic, and System Operations; the ATO Office of Safety; Office of the Service Center;
the Air Traffic Safety Oversight Service; the William J. Hughes Technical Center; and the
Mike Monroney Aeronautical Center.
7. Background. The FAA has not yet issued final standards for this aircraft. Pending the issuance of
such standards, the ATO will continue to issue interim guidance to support the operation of the B748
aircraft in U.S. controlled airspace.
8. Safety Management System. The analyses of computational models suggest that the B748 wake
vortices are similar to those generated by the B744. The separation standards and procedures contained
in this notice are conservative. Flight test data is currently being collected for the B748. Final guidance
will be issued once the flight test data have been evaluated.

Enders (Airbus) dice que la disputa con Boeing ante la OMC es "absurda"

En declaraciones realizadas en el diario 'Financial Times', Enders destacó que mientras ambas compañías discuten ante la OMC por unas ayudas estatales que las dos han recibido, los únicos ganadores serán sus rivales de países emergentes como China y Rusia.

En un ejercicio de sinceridad, Enders reconoció que la OMC seis años después de que comenzara esta batalla, como era de esperar, encontró que ambas empresas "son culpables".

Boeing 787 Suffers Engine Surge During Flight Tests; Deliveries May Slip Again

Boeing and Rolls-Royce are investigating the causes of a Trent 1000 engine surge that has grounded flight tests of the first Boeing 787 at Roswell, N.M.

Boeing also is assessing whether the latest engine incident may cause further slips in the hard-pressed 787 delivery schedule. The failure occurred on Sept. 10 during ground tests of the first 787, ZA001, which was at Roswell for Block 1 rejected takeoff work, plus brake demonstration certification and stability and control tests. The aircraft, which has been based at Edwards AFB, Calif., for most of August for runway performance work, was on its second visit to Roswell, having earlier been there for wet runway testing.

Que vienen los Indios

En India existen unos 400 centros educativos científicos, de los que salen cada año 200.000 ingenieros y 300.000 matemáticos, físicos y químicos. No es de sorprender que semejante producción de jóvenes preparados sea una fuente primaria de exportación: el 12% de los científicos que trabajan en Estados Unidos, y el 32% de los matemáticos de la NASA, son Indios.

US airborne laser /ABL) fails 2nd shootdown test in row

A converted Boeing Co (BA.N) 747 equipped with a powerful laser failed to shoot down a mock enemy ballistic missile, the Pentagon's Missile Defense Agency said on Thursday, the system's second botched flight test in a row.

Preliminary indications are that the so-called Airborne Laser Test Bed tracked the target's exhaust plume but did not hand off to a second, "active tracking" system as a prelude to firing the high-powered chemical laser, said Richard Lehner, an MDA spokesman.

"The transition didn't happen," he said. "Therefore, the high-energy lasing did not occur."

Boeing Statement Regarding USDA-FAA Partnership on Aviation Biofuels

CHICAGO, Oct. 21 /PRNewswire/ -- Boeing (NYSE: BA) Vice President, Environment and Aviation Policy, Billy M Glover, issued the following statement in the wake of today's announcement by the U.S. Department of Agriculture and the Federal Aviation Administration that the two agencies have agreed to work together to bring sustainable biofuels into production for the aviation industry.

"Today's announcement is welcome news for the commercial aviation industry, which sees sustainable biofuels as a key element of its plan to lower its carbon emissions. Through test flights with a number of our customers, we have proven that fuels made from plant matter and algae can power jet aircraft safely and efficiently, and we look forward in the months ahead to the approval of these fuels for commercial use. The challenge then will be to prime the production pump, and bring biofuels to an attractive price point for airlines. Boeing is currently working with the USDA and the Air Transport Association on the Farm-to-Fly initiative, which seeks to encourage the production of sustainable aviation biofuels through U.S. agricultural policy. The USDA-FAA partnership will further help in that regard. We applaud their efforts and look forward to working with them to commercialize biofuels that can help the aviation industry meet its aggressive carbon reduction goals."
