Flown the RJ series for a number of years and yes, if you want to go down/slow down these speedbrakes are amazingly effective! If you really need to get down quickly on a 737 then drop the gear, flaps 40 and LVL CHG. Holy cow. Or Gear DWN, Flaps 10 and speedbrakes works too. Had an FO show that to ...Jump to post
Fred You have put a lot of work into that post well done. Yes I do think the GE9X engine could power the 77W, likewise I think the GE90-115 could power the 779 to start flight testing. The only issue with the GE9X on a 77W I do not know about is ground clearance. Not sure if they changed the mountin...Jump to post
From what I've heard, it was a compressor stall that jarred the spinner loose.

If I bought a new A350 and operated daily, how many times would be reasonable to expect that an engine has to come off? In theory never. The Trent XWB produces an enormous amount of data (as does the aircraft), if any parameter is trending the wrong way the engine will be removed. The engine config...Jump to post

My results from wind tunnel test are: 2D test Lift:301 Drag:122 3D test Lift:214 Drag:94 (Note once again,AoA is same for both tests,I didnt increase AoA on 3D airfoil to compensate lift reduction because of tip pressure loss..)

No idea how they located a part so deep in ice, and then managed to recover it in what looks like a very remote location.Jump to post
Right down to the axle. Looks like a new MLG strut, too, that will need to be replaced. Glad everyone is ok! They have new wheels on it pretty fast to tug it away Avherald says the crew advised they expected to be able to vacate the runway.

Why are the engines glowing? I've never seen that on a subsonic airliner. They all do it, if you have the correct lighting conditions and angle to look up the tailpipe. Being a 3 engine takeoff TOGA is mandatory, where TOGA is not usually used on most airliners all that often. Trading an A346 for a...Jump to post
One engine with full fuel and load (obviously not in this case) but no , it can stay aloft barley.

You can manage to landing it if you had the height to jett...Jump to post

There supposedly was talk of reversing out of the gate, but that idea seems to have been dropped.

Technically spoken, anything is possible ;) But the TC holder didnt offer it, no STCs available. Boeing offered the ACT Option for the 77L from the shelf, so they are there.

The reason for this is a UAV was shot down over the gulf of Oman in the 20th. The UAV was at high altitude, and the size of an airliner (Global Hawk). That and two ships attacked by missiles.

From a lightly loaded a350 - 20t payload, 9.5hr trip, avg fuel burn only 5.1t per hour. What a difference getting higher sooner makes. You wouldn't buy an A350 for that, that is an A321XLR profile. Probably a seasonal load one way. That would mean payload of ~26T for QF9 and ~29T for QF10. Looks li...Jump to post

The mats does not add up for me.
Mach 2.2 at FL600 is close enough to 1260 kts, SFO to NRT should be about 3.5 hrs (4500 nm), the maximum endurance of the aircraft.
Why the 5.5 hrs SFO to NRT ? That’s more like Mach 1.4.
200 x 105 = 21tonnes. So seat numbers in excess of 200 must lead to some loss of fuel? [assuming that they were not fuel volume limited at 20.9T payload] [It'd lead to loss of range anyway through incrementally higher fuel burn, but thats not really what we're talking about.] I have only seen the l...Jump to post
Also, Airbus quoted range on 90kg per pax, 105kg is more typical per passenger. The A320 with 2700nm range in B6 config had issues flying 2400nm LGB-JFK.

Unless grossly overfilled, an O2 cylinder will not explode "just like that" due to overfilling; from memory, they are tested at least at 150% of the normal operating pressure, so it'd take a lot to make it explode.
