Etops 757 Questions?

Sat Dec 01, 2001 6:33 pm

What current nonstop 757 routes originating in the continental U.S. require ETOPS certification besides Hawaii and Europe? Is ETOPS required for flights to Bermuda or other Carribean destination? I ask because I read that AA has 14 ETOPS certified 757's and UA has 16. Why so many if they're only used on the Hawaii runs? Or are they?

All twin narrow and wide body aircraft should be maintained ETOPS. But dont have to be.

ETOPS is any route that contains a point farther than one -hour flying time, at approved ONE-ENGINE crusing speed under standard conditions in still air, from an adequate airport. IN other words im flying a route I lose an engine and im more then one hour away from a suitable airport. Its considard ETOPS.

The CMP standard defines the ETOPS configuration requirements for the engine and airframe systems.

There are 75 120 138 180 and 207 {777-200} - minute ETOPS diversion authorities the 75 min started in 94 with the 757-200 . Hense as the Twin aircraft equipment and ETOPS program's matured the engine out deversion flight time's increased.

Yea, I know what ETOPS is, but I'm just addressing 757 ETOPS on US Airlines. Actually, to keep 75's ETOPS certified much higher costs are required because they are not certified out of the factory like 76, 777's. In other words airlines spend lots of money to keep their 75 ETOPS standards current. Why would AA and UA maintatin 14 and 16 ETOPS certified 75's respectively if those aircraft are only used on 5-8 routes (to Hawaii). I know at least AA flies 75's to Carribean destinations such as St. Maarten and Bermuda and I was just wondering if these Carribean routes are far enough from a suitable diversion airport to require ETOPS.

CO's 757's are all ETOPS certified from delivery with Boeing. We were flying the 737 EWR - BDA and they are non ETOPS routes. Haven't looked lately at the schedule to see if we use them still.

I know we are using 737's on ETOPS in GUM, but I do not know the particulars about those ops aside from the APU must be run continuosly.

BTW, the 753's are going to be non ETOPS
