Looks like the FAA is sacrificing safety in the name of putting more airplanes in a smaller space!

Here's the notice from the FAA:

http://www.faa.gov/documentLibrary/media/Notice/N7110.525.pdf

[FONT=ARIAL, Helvetica, Geneva]Quote:
Appendix A is being revised to harmonize FAA weight category standards with those of the International Civil Aviation Organization (ICAO). All aircraft that weigh more than 41,000 pounds, maximum certificated takeoff weight, up to but not including 300,000 pounds, will now be classified as a “Large” aircraft according to FAA standards. Aircraft capable of takeoff weights of 300,000 pounds or more, whether or not they are operating at this weight during a particular phase of flight, will now be classified as a “Heavy” aircraft according to FAA and ICAO weight classification standards.

This change reclassifies all B757 aircraft as “Large” aircraft; however, controllers are required to apply the special wake turbulence separation criteria as specified in paragraph 5-5-4.

yeah, not necessarily less separation, just a different name. You'd have to have that paragraph in front of you to know if the separation for a large is less than a heavy

So they are changing it but leaving it the same?

5-5-4 MINIMA
e.2:
1. Heavy behind heavy- 4 miles.
2. Large/heavy behind B757- 4 miles.
3. Small behind B757- 5 miles.
4. Small/large behind heavy - 5 miles.

RJ's used to get 5 miles, now its only 4

Your own quotation seems to indicate otherwise: "However, controllers are required to apply the special wake turbulence separation criteria as specified in paragraph 5-5-4." I see no change to separation, only the classification.
 
all i can speak for is DTW and they launch you the second those 75's are 4 miles away. I just take some time powering up.
 
First the launch you when he is four miles away because by the time you accelerate and rotate said jet is five miles away as he is traveling faster and accelerating from a fast speed as you release the brakes and start the takeoff roll.
Second, they just dropped the "Heavy" from the 757's over 250K lbs. 757-300's. The separation will remain the same, but the 757-300's will no longer be called heavy.
 
I have been rocked by 757 wake in an RJ. It is not fun, 30 degrees of bank and autopilot knocked off.
 
Good heavens?!? Whatever did you do? Did Tim Martins save the day?

Sorry, just having some fun...

Tim Martins would have taken the plane around "the long way" to right it, then go rescue some puppies just as soon as he was done completing a crew report.
