Also did all the QANTAS -200’s all have the -7J motors when they arrived? Or did they have other variants in them as well? I hate being up old threads....but....an Australian site in Australian airlines and fleet show that all QF-238’s ( before those ordered with RB211’s) had the -7F, not -7J. Stra...Jump to post
So with world routes 2020 starting tommorow, it will be interesting to see what happens in terms of new routes. Often the announcements only involve the host. ADL is the host. Can’t wait for AA/QF to announce ADL-LAX :spin: Why? That would be downright horrible. What is it with these ultra long ran...Jump to post
Surprised all those 741’s were kept with the -3A’s when an ‘easy’ conversion was available well before that. Or is that all the original frames and engine combinations? Airfleets lists all -100’s with the -7A’s. Also how many -100’s had the 750,000 gross weight limit rather then the 734,000 lb limit?Jump to post

Sorry to bring up a 4-day old thread, :p, but I’ve read that the early KLM -200B’s had the JT9D-7W fitted.
I’ve heard of the -7 and -7A. But what is the -7W? Is it the 45,500lb -7 with the water injection?
If so, why didn’t they get fitted with the more powerful-7A if it was available?
I just had a few questions regarding the early 741's BOAC used. I recall reading that the first orders had the -3A engines then the next order had the -7A's. Is this correct? Also what were the gross weights of the aircraft? I think being -100's they were all the 735,000lb airframes? And if anyone k...Jump to post
Out of curiosity from a no -Flyer, are those ‘unreliable airspeed’ charts fairly accurate? I’ve seen a couple here and there. If it says at a certain weight and max climb thrust (always seems to be at 290kts), you’d achieve a 1600ft/min climb rate, is that reasonably accurate? Perhaps give or take a...Jump to post
Non pilot but a King Air B200 fan. Lived close to an airport that often had the RFDS B200 fly low over head many a time after takeoff. Sexy aircraft. Purely from an interested persons sake is the basis for these questions. Spoke to someone once who told me at ISA+20 with normal cruise TQ, a brand ne...Jump to post
Thanks all for the explanation as to the - at times - shallower descent (not decent,; bad spelling by me) seen on flightaware etc. One more question being the huge 747 fan that I am. If that’s ok? It seems when one wants to increase rate of descent, the IAS is increased. I.e 330kts FL CH vs 280. Do...Jump to post

[twoid][/twoid] Many pilots will set the vertical speed at -500fps (the minimum expected by ATC) for a cruise descent unless ATC asks for more. Much gentler for the passengers. Besides we typically want to stay up high as long as possible. Oh ok, that explains the shallow decent i sometimes see on f...Jump to post
Generally speaking, on a 400 at around a medium gross weight of around 250 Tons, an idle descent from 370 should give you around 2500 FPM indicated. Depending on head/tailwinds the actual descent will be lower/higher. The change in pitch would be around 3 degrees from what level flight was. Thank y...Jump to post
Just after some typical pitch and decent rate figures at idle thrust. Noticed on flightaware the decent rates are pretty modest although I can’t veruify how accurate they are. Most are around 2000- 2200 ft/min from FL370-380. And one was around 500-700 ft/min which is very modest. Is the first examp...Jump to post
I say avoid both and for half the price you can get ahold of the iFly 747 V2. It's $59.99 and does at least 95% of what the pmdg 747 does. http://www.iflysimsoft.com Add in the fact it can fly RNP RF legs (although not on the actual aircraft), you'd say its the same with much better FDE for hand fl...Jump to post
True I guess. None of this matters one way or another at the end if the day. Purely out of interests sake is all. Some FAA type certificate data sheets state at standard temps, SL, 5 min limit 46150/47000 lbs dry/wet thrust ratings. Boeing docs entitled ‘Startup Boeing” state same conditions up to 8...Jump to post
Looking at various documents here there and everywhere (internet and for hobby only) for this particular engine on the 747-100/200, I’ve seen various thrust ratings. Some of them vary by a decent margin. I know it had a ‘wet’ thrust rating. I’m looking for Info on the ‘dry’tnrust rating. So far I’ve...Jump to post
FS9 is the last of the genuine flight simulators. Forget FSuX and P3Dud. Pureley to satisfy the 'gamer' crowd. Washed out graphics and cartoon features. I downgraded to FSX with ORBX airports/scenery and PMDG and everything else. Realized how crap it was and moved on up to FS9(and iFLY - more compre...Jump to post
Thank guys for the accurate information. Also I'm chasing some info for the -200 with the R211-524D4 motors. At max GW (833,000), what would a typical initial cruise altitude be? I've read here and there FL290-310? Would that be at ISA temps? If it was say, ISA+20 etc, would you expect that to be lo...Jump to post
According to some info I was reading, the 747-300 wing was slightly resdesigned to allow a Mach 0.85 cruise vs the 0.84 cruise for the -200. Does that mean the -200 couldn’t achieve M0.85 in cruise ...at all? I’ve seen charts that had the -200 with a max cruise speed of M0.86. Im guessing this was a...Jump to post
IIRC, both PA and TW upgraded the -3A to the -7A due to the increased reliability. I could be wrong, but I can't remember a -7 on any 747. I know NW upgraded their 100s from -3A to -7A also. Ok thank you. I’m guessing the -3A wasnt used for any length of time. And does anyone know what gross weight...Jump to post
HI, I was wondering what engines were used in the 741 fleet by these two airlines? Did any use the JT9D-3/A engines? I've read somewhere that many of the 741's with -3 engines were replaced with the -7's. Was this the -7's or -7A's?
Any help greatly appreciated!
Hi, I am chasing some information regarding the 742 with JT9D-7J engines. I think some of those air frame / engine combinations had the 803000 lb MRW? I'm after particularly the climb EPR settings. I have that for the -7R4G2. I'm wondering whether the -7J was similar as far as setting climb thrust w...Jump to post
