What is needed to turn the tide for good is Diplomacy. It should be blatently obvious to everyone by now that Ukraine does not have the troops on the ground to beat back the Russians. They never did have and they certainly don't now. And the only major Country even contemplating sending their own t...
Jump to postMost airliners tend to eventually see their larger variants become more popular. In fact, it seems to have happened to all major modern widebodies I can think of (well, those that have more than one size variant)... 767, 787, 777, A340, A330. The longer variants always seem to win out. I'm sure ther...
Jump to postThe XB-1 doesn't have the same avionics, engines or even the same general shape of as the Overture meaning that it is of rather limited value as a demonstrator.

Jump to postIs there any indication anywhere that these subs are related to tech issues? If a route is scheduled with a specific aircraft can you educate the rest of us why they’d swap it for a different one if it’s *not* tech related?

Jump to postAccording to JAL, the cockpit crew told them the aircraft was completely uncontrollable after the impact.

Jump to postI agree and I also find it unacceptable that that many lights at the airport are non-functional. To me it speaks to larger issues of deferred/insufficient maintenance.

Jump to postI wonder if the A350 having an aluminium nose section possibly helped save lives of the crew upfront?

Jump to postJAL A350 are all fitted with dual HUD. I can see JAL pushing to implement such "runway night intrusion check" system on it.

Jump to postI am no pilot so could someone enlighten me as to how TCAS would function in this situation? Would it give the, “Traffic, traffic,” call? As the offending plane didn't have an ADS-B transponder and so didn't broadcast signals for the TCAS, the landing A350 was essentially blind. On or near the grou...
Jump to postAs stated by Flipdewaf and Polot above, in the context of a large jet engine, the only type of SFC used is TSFC since thrust is the predominant metric used to measure engine performance. I’ll remember that when I read about CF6-80C2 engines like the LM6000 which use lb/shp.hr or g/kW.hr I'm not sur...
Jump to postYou can't adjust for thrust when thrust is already accounted for in the unit itself: g/kN.h = grams of fuel per kilonewton of thrust over an hour (lb/lbf.h in 'muricanese). The units for SFC are kg/kW.hr, the units for TSFC are kg/kN.h. Everyone in industry know that they should have written TSFC, ...
Jump to postThe GE9X at 105 klb is a 8.69565% decrease in the thrust of the GE90-115., if it’s 10% better SFC than the, GE90-115, its only a 1.30435% improvement over the GE90-115, as 8.69565% is coming from generating less thrust. The GE9X does not have a better SFC compared to the GEnx, it burns several tonn...

Jump to postI used to know a US Army mechanic who worked on choppers and who did several deployment in the ME.

Jump to postI feel there was a thread about that recently... can't seem to find it. The production freighter has an increased MZFW (but the same MLW). It also has a rigid FWD bulkhead instead of a net on the conversions, which changes the courier area layout quite a bit. Obviously, pax windows are factory delet...
Jump to postDo Airbus airplanes have fixed takeoff derate settings also, such as 10% and 20%? Or do you guys just have the FLEX setting, which Boeing calls an Assumed Temperature Thrust Reduction? What do you use for climb derates? Airbuses offer a number of fixed derate options for takeoff, up to 6 on the mod...
Jump to postI also doubt that Airbus will increase the MLW or MZFW of the XLR. The goal is more range, not more payload. Since the XLR is generally destined to be used on longer flights than its shorter-legged siblings, brake temperature is going to be even less of an issue. Even then, if an operator decides to...
Jump to postI've got a couple of friends that fly into SFO regularly. Seems that they're autolanding far more often than what's been described here.
