This one's more impressive than that!

Not at all impressive Captain, I thought they always happened at V1. :p

I assume they just fired the engine bottles, but then they seemed to taxi away before the fire trucks had made an external visual inspection of the engine. The flight deck warning might have gone out, but wouldn't you want 'eyes on the fire' before next decision? |
Rat, that wasn't an engine fire and certainly not an "explosion" so in all probability no fire warnings and no bottles. It was an ornery engine "failure", ie surge or stall where the fire that's meant to stay inside the engine momentarily escapes to places it shouldn't oughta be. Indications on the flight deck are one or more banging noises or woompfs and as the aircraft yaws off the centreline the rapidly changing ratio of tarmac to grass in the windscreen is a big attention getter. If you had the spare capacity you'd see a major rise in EGT and excursions in N1 and N2 or EPR plus a powerful and all-pervading impression that things just aren't going quite as they should. A slow speed asymmetric reject like that is the more difficult one to control in yaw and can cause biiig deviations from the centreline as there is no aerodynamic help from the rudder (plus, as said above, it's meant to happen at V1 not on the piano keys and can take people by surprise). Procedure is to stop on the grey stuff, not the green and preferably still facing the original direction of travel, shut down the engine and extract the seat cushion from whence it is clenched while wondering briefly if any of this was your fault. An external check for further signs of fire or severe damage leading to leaks/debris being spread around certainly might be a good idea but if there's a fire you'll soon know about it - the aeroplane, cabin crew or the radio will tell you. Then taxi back on the other engine, tell some mild fibs to the pax and return to hotel for tea and medals.

Idle curiosity-driven quick question - having watched the video of the ANA 787, is deploying reverse thrust on the engine in 'distress' standard procedure?

Idle curiosity-driven quick question - having watched the video of the ANA 787, is deploying reverse thrust on the engine in 'distress' standard procedure? For this specific incident, I doubt the engine was in distress at the time of landing. being an advanced engine design It could have been retarded to a lower power setting and would still be useable at reduced thrust or simply shutdown by the pilot. The pilot has choices but would typically react according to his training/SOPs |
is deploying reverse thrust on the engine in 'distress' standard procedure? I elected to make a fly-past for a gear inspection I'm not going to second-guess the runway length discussion and landing on the numbers may well have been sensible and justified. However, as I'm sure you considered; just because it can be used for takeoff it does not mean it necessarily has the PCN for landing. |

stretching the friendship there, Pontius... Having said all that, I'm a tad confused by what RAT 5 has written. If he wanted to 'dip under' the GP once over the end of the runway, in order that he could plonk it on the numbers of the displaced threshold then I can understand his thinking and am convinced of the logic in making use of the runway length, versus putting it down in the TDZ of the displaced threshold runway. But he does mention, "The full length was available for takeoff, so the runway would sustain our landing". That, to me suggests landing before the displaced threshold, about which I do not agree, hence my suggestion of bearing capabilities (even if I did use the incorrect verbiage) :ok: ......and there's me saying I wasn't going to get into this :ugh: |
Aren't displaced thresholds there due to obstacles in the approach path, not because of runway weight restrictions?
Also, I seem to recall that the Singapore B777 engine fire was ignited after reverse thrust was used on the engine in question. Things are often not clear cut & a 'one size fits all' approach can often lead to problems. That being said, often with an engine fire it is better to use reverse on the engine with the fire if it is still operating. Just get the thing stopped & the people out. If it makes the fire worse it may not matter - the people are getting out of the thing. But what ever you do, there will the 20/20 hindsight brigade there to critique your performance, from the safety of their armchair. It won't all be bad - there will be some robust discussion that most will learn from. But there will always be some who can't get out of the way of their ego long enough to to think logically & rationally & consider other points of view. Those you just have to do your best to ignore. |

Regarding the ANA. I imagine there was a significant "BANG" associated with the failure. On Airbus - both reversers are selected. Analyse using all available resources - even open the DV window and look. If damage suspected or obvious, discharge one agent.
This will have dealt with the immediate threat (outside). The next threat comes from inside - you have 200 people sitting there grabbing the arm rests thinking WTF? In these days of social media, filled with videos from inside aircraft of burning wings and of evacs as people gather their belongings :ugh: - it won't take much for someone to pull an over-wing exit in panic. Your next priority - once the engine is secure - is to reassure the cabin and then get a report from the Cabin Manager as to the "mood" in the cabin. I never understand the desire to vacate the runway so quickly. The runway is now closed as it will require inspection before any further ops are allowed. Additionally, just because you've discharged an agent doesn't mean to say that you haven't got a hydraulic or fuel leak as a result of collateral damage. Get it inspected, talk to the fire crews and only when totally happy it's ok to move, taxi with them following in case the situation deteriorates. Just my tuppence worth. A4 |
"The full length was available for takeoff, so the runway would sustain our landing".
Brain fart guys. Not sure what I was thinking and totally agree with you. What I was meaning to say was landing on the numbers, not before. I might have been thinking along the lines that as the full length was available for takeoff there must been no obstacles over that piece of tarmac for 'dipping under'. I worded it badly. |
