Many pilots enjoy hand-flying the aircraft during the approach phase. no AP no AT ! return to basic anf have a safe fly and safe landing!

Most likely the reason we can't hear the MAYDAY is either due to the limitations with regards line of sight that the amature's reciever set location used in the uploaded videos etc, or that VHF L TX is located on the underside of the fuselage IIRC, and was probably scraped off.

Do you blame them? So many of my sim sessions in the sandpit split by min rest then followed by a back of the clock sub-continental run on min rest. Who wants to spend an extra 30 minutes in the sim so their buddy can practice a go around or a visual approach??

That isn't the ATC tape. It's an edited hodge-podge from a backyard radio recorder.

Of the occurrences that do happen, improper management of the energy state is a significant problem.
All caused by the issues Rat and Olster have raised. Pilots can't fly/be in tune with their machines because they are not allowed to be due to not-enough training (including recurrent) and lack of regular hand-flying.

Isn't this topic more about possible mode confusion than hand flying skills behind the power curve this time?

Float or bounce

SLF here.

So they talk about a long float and the decision re GA, but they don't actually mention a bounce or any ground contact. What am I missing ?

Yes I have read all the posts to date.

IMHO an occasional manual sim exercise is no substitute for doing it every day in the real ac/. However, I do appreciate and sympathise with the long-haul guys, with 3/4 pilots, who have to share out 8 landings a month along with autoland recurrency. It's not an easy solution, and it might be those pilots, who at the end of a long boring sector, are faced with the need to suddenly sharpen up and re-discover those long hidden skills. Difficult; eve more so if they were never there in the first place.

Our mob drill into us on conversion to type that we must ensure that thrust is set and that positive rate of climb is established BEFORE the gear is retracted- all of this to avoid what happened at DXB.

When will GCAA release detailed hours, last check, last medical of the crew?

Did crew failing to power up led to best outcome? ie., frame just settled within airfield and everyone got out safely.

What would have happened if they spooled up late?

Possibly, however if you're in tune with your machine you'll quickly realise through the seat of your pants the power didn't come on like you thought is was going to when you hit the button.

Come on notapilot, what is so important about those that they can't wait for at least the interim report? What will they prove? Fair enough we discuss what might have gone wrong, but gory details like medicals and dates of last check? Seriously?

RAT 5 and Olster - excellent posts and I would only add that the problems observed in basic handling and airmanship go deeper than type, line and recurrent training; the basic disciplines that we would have learnt are simply not being taught or examined as comprehensively as they once were - ask an instructor at one of the larger ATO's, training cadet's for low-cost and also EK at the moment in the U.S. to demonstrate proper attitude flying and I think you would be surprised at how basic professional pilot training has been eroded in the interest of cost saving over the past fifteen odd years.

Am I spoiled by Debby? If I recall correctly NTSB gives out these within first couple of days of investigation, to reassure public crew are valid and current.

Captain, when I said medical, I meant date of last medical check, not gory details.

Agreed however one thing about the 777 is there is no pitch power couple so on a goaround you still have to pull back quite hard (whether the thrust comes up or not!)whereas on say, a 737 you are pushing forward on a goaround.

And do the systems relief the pilots enough, to give them that extra capacity
I am of the opinion that there is a point where the automation stops freeing up mental capacity and starts eating into it. I often see busy ATC environments where the PM is tapping away at the FMC trying to get something to happen when really all we need to do is lift the nose and reduce thrust or something similar. Sometimes I just tell them to stop and explain how we'll do it so that they can rejoin the party.
I feel for pilots who have not had a few good years of manually flying before joining an operation that is heavy on automation because they haven't developed the skill set to the degree that older pilots have, basically it is an uphill battle for all but the most talented ones.

Question RE issue of climb rate

What seems to be missing is why positive climb was ' called' perhaps prematurely. SLF here but generally familiar with energy issues. Even near landing speed, there is a LOT of interia available for what might be called a zoom climb- trading speed for altitude in short term. NO additional thrust required. However after perhaps a few hundered feet gain at low speed, without a major change in energy available ( thrust) or a major decrease in drag, the plane will then drop or stall.

Perhaps- just perhaps- a premature callout of positive rate or positive climb in this case was significant.

Would there be any advantage in say counting to three to five seconds AFTER observing on insruments a positive change in altitude BEFORE calling out Positive Rate or Positive Climb. ??

No, if there is no thrust on (or only approach thrust) you won't get anywhere near "a few hundred feet" high. A zoom climb won't happen.

Other than my misspelling- I was trying to avoid a parsing of energy issues. perhaps a simple explanation would be to consider how a roller coaster works. Starting at the top of a ' hill' the coaster drops at increasing speed due to energy imparted by gravity (coaster falls to earth ) and gains speed - energy gained is a function of velocity squared. Then what happens, the coaster goes uphill, trading speed( velocity) for altitude and approaches zero velocity. NO additional thrust- energy input is needed to ' climb ' . ETC. I was trying to avoid any form of calculation based on lack of specific data ( speed- altitude- drag- lift, etc ) and instead to simply frame what can give a momentary indication of " climb" or climb rate simply due to energy states involved. Whether a zoom of 50, 100, 200 feet was available for this particular case cannot be determined absent specific data, configuration, gear, flaps, wind, idle thrust, direction, etc .

the 777 is there is no pitch power couple
There is, but the fancy pants computers make it feel like there isn't. Don't forget, the 777 is fly by wire, despite Boeing's attempts to make it look like it isn't.
