Re: Why does a 737-700 use flap 1 and not zero flap for take off?

You don’t understand take-off performance—the 737 will do better with a de-rate simply because of Vmcg will be lower and the plane won’t have to accelerate to the higher Vmcg. Also, don’t confuse AEO run with take-off distance required which plans for the OEI case. Do I understand it correctly that...

Re: Would the Lockheed L-500 have been a good airliner?

No, it only seated 73 passengers. Lockheed would have have done a complete redesign as Boeing did. Great military airlifted, esp with modern engines, but uncertifiable as designed and built for a number of reasons. The wing box doesn’t intrude on the cargo deck because it neatly divides the upper de...

Re: Why does a 737-700 use flap 1 and not zero flap for take off?

Remember, at light weights, de-rates will result in shorter TORR due to lower Vmcg at the de-rated thrust. I believe that TORR at MGTOW, standard day, but likely not Flaps 1, probably F10 or F15. The reason for reducing flaps is second segment climb, not take-off run

Gee, I thought WN was bus service!

Re: Why does a 737-700 use flap 1 and not zero flap for take off?

Since Flap 1 extends the LE devices I'd say that there'd be considerably more than just 'a small amount of extra lift generated'. The leading edge devices don't so much increase lift as increase the AoA margin, though of course as you "use" the higher AoA, you do get more lift. Either way...

Re: Airports with longest and shortest takeoff queues

KLGA used to have some monumental lines, I’ve been in the 40s to go several times. Once a B727, EA, IIRC, had a couple of mechanics looking at the flaps while waiting to go.

Yes, easily. Apply to the airline thru their careers page or, I’m sure there are specialty employment counselors for mechanics. Union, hence, seniority based, TPA might not be possible.

Re: What will happen to shorter routes when airlines replace 50 seaters?

I do a run down from central MA to Wilmington, DE—in a car on the worst possible route to drive, I’ll beat the airline passenger nearly every time. Add drive to airport, wait thru security, be there an hour prior, wait ti disembark, get bags/rental car, drive to final destination. A cars is quicker.

The shoreline from Boston to Washington is one of the most traveled routes and the existi...

Re: Accuracy of enroute times months from flight

Not “some idea”; usually a pretty accurate idea. Now, that’s on flight day or the day prior; looking months in advance for scheduling/time tables, they’ll use historical winds. Historical winds can be far off from the actual flight plan.

A missing winglet can be MEL’d, I’ve flown a couple planes configured that way. I’ve seen worse things.

Re: FDX EVS and Adoption Across Airlines

Re: Is there a common speed margin above stall for flap settings?

On the B727 and most airline SOP, that’s true, min maneuvering is good to 30 degrees of bank. But, on the five Part 25 bizjets I’ve flown, maneuvering speed above 15 degrees of bank required an extra 10 knots as did the C-5.
