I haven't been able to find this anywhere. Is the re-engined b-52 going to have 4 or 8 engines? The engines will be replaced one for one. A new nacelle and pylon will also be included. Various other systems will have to be upgraded too. Plus there will be some other systems upgraded during the proc...Jump to post
Can they? Thought the CFR allows that for 4 engines with 1 inop: https://www.law.cornell.edu/cfr/text/14/91.611 Sorry to burst your bubble, but they can't. All of the engine out ferry flights are based on losing the second engine. So, on a twin, it's pretty hard to do one engine take off and then p...Jump to post
It looks as if the Trump Shuttle paint scheme for the new AF-1 might not happen. Supposedly, the proposed scheme is not finalized yet and won't be for a little while longer.

Apparently, last evening a B-2 crashed during an “emergency landing”. No injuries reported and damage to the aircraft is unknown.
[quote="texl1649] You’d be the expert then, not me, but I read that Boeing did replace the upper wing skins on the H models in particular in the 70’s; https://www.forbes.com/sites/davidaxe/2020/05/22/stop-calling-the-us-air-forces-b-52-bomber-old-its-more-youthful-than-a-b-2-stealth-bomber/?sh=...Jump to post
If I recall correctly some of the upper wing skin surfaces were replaced in the 70’s, already, but yes sheet metal under compression/flexing doesn’t tend to hold up forever. I wouldn’t think it would cost all that much to put new aluminum wing skins on them, we’re not talking about stealth coatings...Jump to post
I guess if the wing skin will be replaced, then that is where you get your life extension. bt In reality, the upper wing skin will have to be replaced. They, USAF, aren't going to re-engine the BUFF and then park it. So, my guess is when the winner is finally decided and the cowl redesigned, that's...Jump to post
I suspect there were some loading conditions considered that made it stout. Shock waves of a blast would seriously affect a plane. I recall KC Top Boom bringing up that new wing skins need to occur as well as the number of other improvements that are under contract. Correct. Given the current flyin...Jump to post

Obviously, you have never flown in a 200 with-7 engines!!!
Looks as if the crew was a little off on their estimate of 800 pax. The confirmed total was 640.

Granted there were quite a few VFR travellers, but the amount of belly cargo loaded certainly made up the lower fares. Curious: how would you know that? SQ regarded that route as a money maker. I am not surprised at all it was reinstated. Then why would it take them 13yrs? Well, I worked for SQ for...Jump to post
Before SQ got rid of the 744s, I operated the SIN-TPE-LAX flights several times. The loads both ways were just about 100%.

Maybe I am asking my question incorrectly. I think I am using terms incorrectly. Lets say aircraft x has 25,000 feet as its best cruise altitude for the conditions and it takes off very heavy.

OK thanks....Those are some rather abstract wing walk paths and they are not symmetrical between the left and right side. Just seems rather bizarre.

NW, in the name of standardization, didn't have the dial a flap system on their 40s. It was a Rube Goldberg system that was a real pain. TBH, I was on the 747 by the time the -30s arrived so I don't know if that was changed. I would assume it was.Jump to post

I flew the DC-10 for about a year and then went to the 747. The DC-10 was the best aircraft I have flown when it comes to cockpit comfort. IIRC, the #1 pack was dedicated to the cockpit only.

Just a couple of things from a disinterested party. We can safely state this was not Boeing’s finest hour. However, the debacle is not entirely their fault.

I doubt the USAF, USMC RAF and USN are running with full stealth capability in Syria. The F-22, as far as I know, used their Luneberg lenses in Syria and I can't see the F-35 not using them. All this talk about the SAM environment and stealth in Syria is irrelevant. The US would not take the risk of...Jump to post
Of course, you realize the forum and data you are quoting was from a 2009 posting. If you read the RFP, the implication is a 767 sized aircraft.

Thank you for your opinion. We agree to disagree. My guess is the majority of your time if not all is in an Airbus.Jump to post
What's to understand? Boeing takes a very different approach to Normal Law limits. On the Airbus, if you go to 45 degrees of bank, it automatically returns to 33.5 degrees, IIRC. On the Boeing, if you go to 45 it stays there. The pilot has asked for that for a reason, so the FCC commands that. I hav...Jump to post
Completely different flight control limits when in normal law. To DH106, not sure you are talking about the same thing. The CLmax or max energy line on the PFD is just what it says. The aircraft does not go from there into a stall. The stall is progressive as you slide down the backside of the lift ...Jump to post

[ For one, you can't max perform the wing in the event you want everything out of it. On a Boeing, you can. Just remember, max performance on a swept wing is half the wing in a stalled condition and the wing, unlike a straight wing, stalls from the tip inwards. Swept wings are generally designed so...Jump to post
Genuinely curious about how to reach (and maintain) this condition with a Boeing? How would you accomplish a windshear recovery or a CFIT recovery?
