You are on the right track there with some good examples! |
There is a subtle difference between being tired and being fatigued.
I can't remember exactly where the reference is stated, but the Medical profession and the UK CAA recognise it as follows: When you are tired, you are able to recognise and react to a given situation. When you are fatigued, you are often unable to recognise and nearly always unable to react to the same situation. Given the hours that pilots have to put in before and during a long haul flight, it would be interesting to know who would admit to being "tired" and "fatigued". |
In our company it's ok to have a rest in the flight deck, simple rules, one pilot at the time, advise the back end and schedule a call no more than 45min after being advise just in case the second pilot dosed off. and wake up at least 20min before TOD...but on a short flight they must have been tired before leaving....
Anyways North America has to enforce stronger rules on duty days and ban continues duty, impose restrictions on red eyes and give better protections to pilots turning down flights because of fatigue.....ALPA where are you???? BZH EX cargo driver.... |
I'll never forget finishing ATC nightshifts and, (particularly after having already worked the previous morning shift), momentarily falling asleep on the one hour drive home, not to mention driving thru red lights and stopping at green lights. That's fatigue. Meanwhile the supervisor or senior ATCs usually had the luxury of a 4 or 5 hour nap whilst 'the workers' ran the centre.

Wouldn't a communication failure be a more plausable cause ?
They were on vectoring for the destination, standing by for descend, and finally realizing, this can not be right. Reselecting the right frequency, kicking the box or whatever, and then get in contact with ATC (again). Lost comm is not that unusual. |
Lost com...unlikely and if so, then why didn't they follow regs?
evidently transponder was working, no lost com squak? |
How about missed frequency change. We've all heard ATC trying to contact someone. I recall watching TOD disappear behind wondering why no clearance to descend. No answer from ATC so a check of the chart revealed we had missed a frequency change. We called on the correct frequency but were now way beyond normal TOD. We managed to persuade ATC to let us max rate descend as opposed to a hold to lose altitude!! Red faces but no harm ... no foul!!:*

If you fly your life might well be in the hands of air traffic controllers who have been up all night.. If you have to visit hospital with an emergency, you may be operated on by a doctor who has worked twice as hard as any pilot or controller..... There are plenty more people in the world who manage their working hours without being unduly fatigued - I did it for nigh on 40 years. It's just a matter of managing one's life appropriately. No disrespect to pilots, but having to adjust altitude, heading etc on an autopilot and changing radio frequency every now and then with the odd fuel calculation is not excatly edge of your seat stuff. So a bad nights sleep followed by an uneventful day in a flight deck will but most people to sleep. I say if you feel tired in the flight deck, turn off the autopilot, that'll keep you awake for a while.:ok: |
it would sure keep the pax awake!
|
Not sure that simply switching off the a/p would have that much effect... cars don't have A/Ps and plenty of people fall asleep driving...many years back, my nights flying the Bandit ( no a/p) were plagued by fatigue... I'm someone who can't sleep a minute when travelling as SLF... whatever the time/length of trip, I'm awake... put me in front of those instruments and I begin to be hypnotised by the glow of the lights... lack of sleep..
On one occasion returning to 'Saafend' at the end of a sleepless week of night freight we arrived in the London TMA with totally cr@ap wx.. vis to mins...turbulence, icing the lot.. remember thinking "I'm going to have to stay awake for this" as we closed on the localiser.. remember thinking it again just as a hand slapped me on the shoulder as the F/O realised I was asleep ! I say again.. every bit as dangerous as alcohol and not nearly getting enough attention... |
Mungop: You are quite right, and it is very possible to fall asleep while hand flying an airplane.
To leftseatview: if your hand flying would keep passengers awake, you better turn your autopilot off more often and practice hand flying. I can imagine the new breed of regional pilot. Pay your money upfront and learn to fly, by 500 or 600 total hours you get hired at a regional airline. And they encourage you to use the autopilot. So, for every hour you log, maybe 5 minutes is hand flying. And you never get good at it. Mungop is quite right again, fatigue is not getting enough attention...and it will get some attention with the next fatigue crash. |
if your hand flying would keep passengers awake, you better turn your autopilot off more often and practice hand flying A modern autopilot can achieve a smoother ride at altitude than even the most practiced pilot can ever achieve. One of the biggest myths in aviation today is that we will lose our handling ability if we don't hand fly frequently. I use the autopilot extensively as monitoring its effectiveness is exactly the same as monitoring the other pilot's flying; my performance on check rides has not faltered as a result. Monitoring the autopilot function gives me more time to consider the options and in my experience has not contributed to fatigue a much as flying used to do when I had to hand-fly for hours on end! |

In the USA, it is not uncommon for pilots to "commute" many hundreds of miles to their pilot base. For example, I know for a fact that there are plenty of DL pilots who still live in the suburbs of Boston even though the BOS pilots base closed years ago.
A fellow I knew well used to leave his suburban Boston home around 1130AM, head for Boston Logan, take the 1230 or 130PM shuttle to LGA, taxi to JFK in time to captain the JFK-SVO flight leaving approximately 5 PM. After 9+ hours at the controls, there's the landing at SVO at what is about 2AM body time. Mitigating factors were that there was an extra relief pilot on board, allowing the chance to catch some sleep, and the fact that he had to do this trip only 5 times a month or so. My point is that at least in the US, many pilots are traveling many hours simply to get to their cockpit! |
Coincidentally, Air Crash Investigation on the National Geographic channel today was about China Air 006, when a fatigue induced error almost caused the loss of the aircraft. The 747 FE missed a check item and it all went horribly wrong............
Think it's on again later tonight. IMHO it's well worth a look. |

I really have to agree with Huck on this one. If you don't practice, you won't be very good. You indicate the superiority of the autopilot at altitude. I really wonder how well you would do at max op alt, with the autopilot off or out of service. Maybe you would descend. Maybe you would be all over the sky. Or maybe you might hand fly to altitude, trim, set power/thrust and let go for a few seconds before engaging "george". But as Huck said, the horse has been beaten to death before. |
Three FD crew should be the norm...
First Officer looks after navigation, makes required ratio calls, keeps the plog. Flight Engineer sees to it that said First Officer stays awake to do the necessary. Captain rests (snoozes). F/O gets tired, Captain takes over and the F/O rests (snoozes). F/E gets tired, Captain keeps an eye on the FE panel, and F/E rests (snoozes). When all three are tired, the aeroplane is landed, which oddly enough, is normally at the scheduled destination. When all three are fully awake, newspapers are read and Havana's are enjoyed. Piece of cake.:} |
Except the tiny flaw with the suggestion that you turn off the A/P and hand fly, is that within RVSM airspace an A/P is required.
