Delayed start on B757

[Spooky 1]

Any UPS guys/gals out there that are using a delayed start procedure in the RR powered B757's. I know that the Boeing FCTM does not embrace this procedure yet I suspect that there are some operators that have adopted a policy that allows for this under certain circumstances. Any opinions are welcomed and the whys and why nots will all be considered.

2 years on the airplane and have always started them in the chocks or on the push-back.

By delayed start, I'm assuming you mean keeping one shut-down for a portion of the taxi?

We have a delayed start/single engine taxi on ours, no problems.

Doing your single engine taxi on the right engine I assume and then starting the left engine with how many minutes to go? Are you Part 121? Please confirm you are RR and not P&W.

RR, ATA. Usually start R first. Only when a significant delay is expected (like 20 mins or so). SE taxi limited to less than 210,000 lbs., although I think 190 is my personal max under most situations. SE taxi w/either engine, as you know the PTU will actuate with the L engine shut down. Not a problem, at least you know it works. Remember 3 minute warm up before takeoff, give it five if it's cold and first flight of the day.

SE taxi only approved during the day or at night only w/apu running, apparently an issue with nav lights if you lose the gen. believe it or not. Never taxi SE with wet or contaminated conditions, power up and she'll head for Mrs. Comstock's Shythouse faster than you can say oh &^%&$$!!!!

Spooky ... this is not a procedure we recommend for you old farts, it's just too dangerous. <g>

Actually UPS is looking into single engine taxi and mgmt pilots have been doing an evaluation for several months. I think we'll see it soon. Can't see how taxiing on the R vs L makes much difference. Alt brakes work fine ... nosewheel steering is off the left (vs the R via the PTU) ... it's a toss up unless I'm missing something really obvious ... is that what you were referring to?

Youthful BBB!

TWA did it with the 762/763/757's. Generally the right engine was used unless you had to make a tight turn out (which of course calls into question a S/E taxi in the first place!). APU was required for any S/E taxi. No contamination allowed. I don't remember any weight limit but 190 seems to be a good upper limit.

AA disgarded the SE taxi proceedure because they have enough trouble staying on the concrete as it is. DOH! Bad TC! BAD!

(TC would like to continue but he has been sent to his room)

Thanks for all the feed back. I have done it also in virtually every airliner that I have flown on as a crew member. I am not sure that it would make a hill of beans difference in our corporate operation and probably would be hard to quantify any real savings. That combined with the fact that the Boeing FCTM does not embrace this procedure makes it a questionable practice (at least in this flight department), but none the less I would like to consider it as an option and develop the procedures necessary to implement it, should we get enough courage to use it. For some reason we are on a real accountability $$$ role at the moment.

I will take BBB advise and make sure that there are never two guys in the cockpit over age 60 at the same time, should try this hairy procedure!

There should never be two guys in the cockpit over age 60 at the same time under any circumstances whatsoever (excepting the over 60 FE in a 3 man crew, since there will still be at least one guy young enough to stay awake past 3 pm or to handle things when the feces hit the rotating oscillator).

Forgive for injecting the age 60 issue into what was originally a constructive dialog about the B757. I will no go out and flog myself fifty time for being so senile. IT WAS A JOKE DICK HEAD!

 

[FarginDooshbahg]

So was my post. I thought the "feces/rotating oscillator" part would have given it away. Maybe senility has robbed your sense of humor.

You can carry on with your "contructive dialog" without further interruption from this D!CK HEAD.

Sorry for calling you names. Very poor taste on my part.

 

[FarginDooshbahg]

No harm done.
