My reading of the GE9X is that the low-power rotation system *prevents* the need for dry motoring or extended dry motoring after a normal turn. As long as the system remains powered with a loss not exceeding 5 minutes, then there is no concern about bow, so no need to dry motor. You're right. The s...
Jump to post14 hours?!? Woow. So... no 777X ever will stand around with non- moving fans? Also I have actual questions: where does the electricity come from? How hot is an engine core 8hrs after shutdown. Or 10? I'm amazed by these 14hrs... Only N2 is turned, so you won't see the fan spin. Also the turning is ...
Jump to postAre the engine cowlings shaped like this to preserve the aerodynamical profile of the old aircraft? Presumably, yes. The RR selling pitch included claiming they would work within the existing pods/cowlings, but I am pretty sure new ones will be fabricated in any case as the existing ones are…appare...
Jump to postThis probably means the delays are much bigger/longer than most of us are thinking. If it was only 12-18 months, I strongly doubt they would implement such a program. I suspect we’re looking at a major reduction in velocity of new deliveries.
Jump to postBut I disagree about the lease terms. If these were unassigned or if they are deferred then that actually gives United the leverage in this case. Otherwise the lessor is left covering an aircraft producing no revenue for an airline and no revenue for that lessor either. It appears that UA and/or th...
Jump to postThe skid marks shared by the pax in the KHOU video suggests they started skidding when they went to slow for the turn, and simply ran out of space. I wonder if engines spooling up for take off on RWY-9 left oil deposits that made that area particularly slippery with the rain? No. They attempted to ...

Total bs. Having worked in that tower for many years, no regrets from the controller.......
Jump to postABC13 spoke with a passenger who was on the plane the moment the incident happened. He says there was a "huge pop" before the aircraft tilted over, catching the passengers by surprise. So perhaps it was a blown tire? Could be, though passenger accounts are largely unreliable. Mostly proba...
Jump to postThankfully, pure luck prevented any major injuries or deaths. Personally I'm inclined to give the crew a bit of credit for remaining calm, and getting the plane on the ground safely in difficult conditions. Not just "pure luck." The crew performed their jobs exactly as they were trained t...
Jump to postHonestly, what’s the point of getting that aircraft airworthy and then fly it to the US for what? They should have scrapped it in Argentina and let it go. Likely to be torn down and analyzed as to where Iran was getting parts, and to identify what sort of domestic Iranian capability is there to rep...
Jump to postThis has become ridiculous. Either the bolted-securement door design meets certification criteria or it doesn't. And if it doesn’t, then what changed between the 39M and 9ER? Otherwise, 9ER should also be grounded. If the concern is such that you can’t justify grounding the 9ER fleet, then you shoul...
Jump to postLOL at the semi-sized tow truck they called/used.
Jump to postAdd: FWIW: it seems the Trent 1000/7000 is heavily incentivized financially to use reduced climb thrust, hence the reported slower high altitude climbs. I’ve noticed SQ also does the same with their 78X. I suspect it’s to improve the TBO/TOW while the durability issues are addressed.
Jump to postRegarding A339’s field performance: the Trent 7000 is only good for 72,900lbs of take off thrust and about 65,000 maximum continuous, whereas a 789 with 1000’s is usually 76-78000lbs take off and 69,000 MCT. Coupled together with the bleed valve issue, and that’s quite a bit of thrust difference. Fu...
Jump to postThank you for the quick answer. This means the 737MAX10's will have more range than the standard A321NEO's at United. I assume these can still make a Hawaii run right? Delta loves sending the NEO to Hawaii so I assume United can make a huge bang for the buck sending those there They wouldn't be pla...

Jump to postIt isn't an entirely new winglet altogether. It's an entirely new winglet.

While overall structure is same shape/form, thick...
Jump to postFWIW, the landing gear is completely fake. Also there are rigid columns further out on the wings.
Jump to postIf the 321neo doesn't have the range to go EWR-SNA UA will have real problems with the 321neo that would be similar to the 739nonER, which is mostly relegated to mid-continent flying The 739ER has a 2950NM range and does transcons and Hawaii. The 321neo w/o aux tanks has a 3500nm range according to...
Jump to postI guess I'm surprised the MAX8 hasn't been scheduled on SNA-EWR. Does that mean it's not capable or with a weight restriction? 738 flies to ORD and IAH.

Jump to postIf UA decides they need a new smaller plane in the fleet, does the Max 7, 319neo, or a220 make the most sense? MAX 8. UA feels the minimal savings in trip costs does not offset the loss of seats. In theory if you can fill up the MAX 8 a few days a week, it will make more money than flying the MAX 7...
Jump to postNo I don't at this moment. When PW straightens out their problems with the GTF? Then I can see it happening. but United's A320's and A319's are powered by the IAE V2500 so unless the V2500 is the new engine? I do not see it happening until and unless the GTF engine suddenly becomes reliable. Keerpi...
Jump to postI understand UA did not equip the regular neo with aux fuel tanks. If that remains true, it doesn’t have enough fuel to go from KEF to IAH, hence the CLE stop. Btw, if true, these won’t be able to do transcons (at least not in the winter) or Hawaii. They should be able to do ORD-west coast. And any...

Jump to postAs far as proof, I don't have anything in front of me to back up my statement. IIRC, the original 77E order by BA was in late 1994 or early 1995.

Jump to postTo be fair, Enterprise did testing having been dropped/launched from the 747 shuttle carrier. This largely validated the landing part of the sequence, which was a big concern in the early days.
Jump to postRead it again. ;) Doh! I meant to ask why they didn’t install it with the BSI sidewalls. Across a large fleet (~150 frames with 73G/738/739 non-BSI) there was probably a material cost savings associated with re-laminating an existing sidewall panel versus installing all new BSI-style panels.

What happens to the passenger in a situation like this? Did the plane taxi to a gate? Clear the runway and wait for the trucks to inspect it? Bus the pax?
The abnormal part is it was 26 *after* boarding. That’s a lot of people. Either there was a big ops mess up that lead to not restricting the plane prior to boarding, or something went tech or a huge ATC reroute requiring a ton of extra fuel happened after boarding started. Almost certainly an A321ce...
