Apron Drive PBB shall accommodate a range of regional (RJ) and jet
aircraft sill heights for aircraft generally in commercial service. Upper
and lower level limits shall include, but without limitation, Boeing 757-
200s to Embraer E145 respectively and all appropriate commercial
aircraft at the gate.


Ok guys who know on variety of aircraft, what does this exactly mean, the jet bridge could handle any aircraft or the 752 is the limit? "but with out limitation"

Yes a new jet way, sources down here in McAllen, all screwed up. They say one thing, then I read another.

Sounds to me like they want a range from 752 sill height (13'2") to E145 (5'4") and any aircraft in between.
Can't think of any limitation that would have to do with the upper and lower level limits.

Makes sense I guess, I was just asking beacuseof the fact that I heard on local t.v. that it could handel from regional airplanes to 747s.

Well the sill height for a 744 would be 16'11", don't understand why they didn't just spec the bridge for that instead. It probably can reach up there anyway.

GAH! In the name of all that is good and right, please tell me that not all airports go through such anal retentive garbage just to add a gate?

I'd be afraid to be the contractor on the project for fear that when the jobs done, the airport authority is going to inspect with a ruler and a magnifying glass and measure the threads in the carpet!

Here's my question. Why include the 757-200, but not the -300? Does the -300 have a higher sill height?

This is legal talk and is written very specifically because everything must be spelled out in specifications for contracts and bidding.

I'll explain what it means, and it is written both correctly and CLEARLY if you know how to read it.

The jet bridge has a limit in aircraft it can serve. The lowest to the ground aircraft it can serve is the ERJ series. The highest off the ground is the 757 series. It can accomodate ALL planes that fall within that range.

But, if they only said that it could reach down to an ERJ and up to a 757, then, by specification, it would ONLY BE ABLE TO SERVE THOSE TWO. Of course, that's silly, but in a specification, you must make it clear that you are meeting a certain criteria exactly. Everything you say or don't say in a spec has specific meaning.

Thus they say:

Quote:
Upper and lower level limits shall include, but without limitation, Boeing 757-200s to Embraer E145 respectively and all appropriate commercial aircraft at the gate.

In other words, this gate has limits, and these two jets are EXAMPLES of jets that define those limits, but the gate is not limited to only serving those two specific jets and no others, but is in fact UNLIMITED in the types of planes it can serve, both existing and future, as long as they fall within the range defined by the two existing models they call out by type.

This is why construction contracts and specifications are thousands of pages long. Because it everything isn't spelled out clearly and exactly, when changes are ordered or bills not paid, it leads to legal action. And forgetting to specify something might also mean an otherwise superior bid on a contract must by rule be excluded due to lack of completion.

I worked for a law firm that resolved such cases in New York City out of college. We had one client that was a powerplant in Pennsylvania, and the contracts and specifications, including each revision set, filled an entire office on our floor with very little room to physically move around. And I had the pleasure of finding the various specification versions and to help decipher this minutia... joy!



Of all the things to worry about... the Wookie has no pants.

I totally agree, SAT and maybe AUS recieve these aircraft by CO, but what "if" CO were to send an757-300 down here to MFE, would that be a problem?

It might be a problem on paper, but I doubt the folks at the airport would "let" it be a problem.

I'm not familiar with the specs. on 753, but maybe the bridge can't extend far enough to L2, or which ever door, due to the stretch in the fuselage.

On a side note, I can't imagine MFE taking 752s, unless they are private/charter in which case they'd use the stairs. But, I might be talking out of my ass.

Nope, all 5 gates at MFE handel 752's,on the other hand, CO all of a sudden sends 752 to MFE.(so far not this year)

How come they never use the 1st door on the 757's? I usually seem them(in general airports) using the 2nd door

It's usually up to the airline. Most prefer to use the 2L door because it is easier to load/unload because in most cases, the 2L door separates F and Y. That way while boarding, F pax go one way and Y pax go the other.
