- One of the sectors I work as a controller at Cleveland Center is a high
- (24,000' to 60,000') altitude sector over southern Michigan. This sector
- works a ton of inbound traffic to ORD, most of it from the east coast and
- New England areas. Our biggest task is to space two constant streams of
- a/c into one line before we hand them off to Chicago Center. This involves
- many speed adjustments and lots of vectors...though the patient controllers
- have found that speed changes are easier for both flight crews and con-
- trollers.
- The differing cruise speeds of our modern jet fleet require alot of
- conjoling and pleading with the pilots. In an American Airlines rush into
- ORD we have to space DC10's and B747's from JFK and Europe, with MD80's and
- Fokker 100's from New York State and New England. At any rate, I thouhgt
- you folks might be interested in the various cruise speeds of the different
- aircraft. (If given a choice, take the faster one, and put your wife on the
- slower one, so you can have a beer at the airport bar while awaiting her
- flight).
-
- B747, DC10, L1011, MD11....mach 83 to mach 85
- B727, B767, A300, A320,....mach 80 to mach 82
- DC9........................mach 78 to mach 80
- MD80, B737.................mach 73 to mach 76
- FK100....(get a life!).....mach 71 to mach 74
-
- These speeds are of course up to the flight crew...I've had B737 pilots
- in a hurry go mach 80...but they burn fuel like mad.
- Our job is to get the fast guys to slow down and the slow ones to speed
- up...or suffer a vector off course for spacing.
-
- The one I'd pick is not on the list and doesn't fly into ORD anyway, but
- if you take the Concorde you'll be DRUNK when she gets there.
