Re: 747-400 climb performance when empty

Well the 747 must be right up there with the MD11 when it comes to climbing quickly (at least when empty). I have heard those birds can do 6000+ FPM on initial climb out! I don't know where you heard it from but it won't. I flew 747s (-100Fs,-200Fs, and -400Fs) for 12 years, and I've absolutely see...

747-400 climb performance when empty

I was wondering what kind of climb performance a 747-400 has when empty or very lightly loaded. 5000-6000fpm initially? If the altitude assigned by ATC isn't too low and there are no passengers aboard, is it still the standard to use CLB2 all the way up to cruise altitude?

I had no idea a 737-800 had this kind of range. Ferry flight back to Southwest's home base at Love Field? I'm guessing they were completely empty to make this distance.

How often do freighters fly with max payload?

How common is it that a freighter (let's say a Kalitta 747 or some other ad-hoc charter) is filled to capacity for a flight? I can imagine it is a little bit more predictable with airlines like Fedex or UPS who, to my knowledge, only fly scheduled flights and don't usually do charters.

It is interesting how airlines like BA and Qantas have already retired their 767's for being old, yet Boeing hasn't discontinued the -300ER (or at least remove it from the list price) completely. Not too often you see planes being retired and still in production at the same time.

Re: Final Passenger flight for the Boeing 727

If you don't count the money involved, you could technically keep em flying forever with proper maintenance. The few that are still flying in private hands will be (if not already) updated with modern avionics to fly past 2020. I'd imagine it would be quite cost prohibitive though.

Since the MD80(without being retrofitted) is not equipped with GNSS, would the equipment code /Z or /L be correct? Early 757/67's as well as the 737CL all filed /Z, so I am assuming the MD80 is the same? It appears that some FMC's installed have GPS capability so that is where I am confused.
