Human Factors Requests

Thu Jan 05, 2006 7:33 am

Hello there,

As I read and search, Human factors are very important in aviation! The responsibility is fundamental as transporting passengers. But one thing that hits me is if pilots do not comply with those normal requests such as; sleep, resting before flight, no alcohol and many others. Are there any occurrence's where pilots did not comply with those requests? Of course if you own an aircraft e.g PA-28 the possibilities of flying with less regulations is higher, but what about commercial flying?

Cheers

There was the rather well publicized case when Channel 4 (IIRC) did an expose on the all-drinking, no-sleeping BA pilots. Including the Captain who slept the entire flite.

Note: Not bashing all BA pilots, just the moronic ones.

Remember, they beef up the facts on these documentaries to make them interesting. I would take whatever was said with a pinch of salt.

Its not just pilots affected by this. Engineers are as well. Infact, Human Factors is one of the courses that is MANDATORY for all engineers to take every 12 months. (along with Aviation Legislation).

Of course. But some pilots were fired IIRC.

BA (to my mind) in the last two years have suspended a few pilots relating to being on duty whilst under the influence of alcohol. Now, CRM states that by LAW they are to be completely T-Total. I doubt the pilots were so drunk that they were unnable to carry out their duty, however i think it is more likely they were caught out in the after-affects of drinking down route...

A good read would be James Reason. He has done lots of work on Human Factors in Aviation and is quoted a lot in other presentations.

currently revamping our Human factors training for our engineers (even if I see your thread start leans towards pilots) and it includes everything from correct tools for the job, shift changes etc and should be done together with health and safety issues I believe (on the issue of being drunk on the job, then you get into labour law issues as well.... lawyers get involved, how many companies do you know with a calibrated breathalizer with a person trained in its use and then there is drug testing..... civil rights issues have to be taken into account)

We cover the flight crew issues under CRM training

Good sites for maintenance/engineering human factors issues are:

UK CAA
Good overview doc
http://www.caa.co.uk/application.asp...pplicationid=11&mode=detail&id=287

FAA (lot of reading here)

Like in any field, pilots are people and people have personal problems. And unfortunately, some try to compensate those problems with alcohol. Even though I do feel that it's quite rare for pilots to show up at work intoxicated, it is impossible to rule out any such occurrences.

Nowadays, CRM (Cockpit Resource Management) is a major thing and training is mandatory. We have come a long way since a few decades ago. The KLM/Pan Am disaster in Tenerife was one of the major catalysts to drive CRM research and training.

The CRM human factors go WAY beyond how much sleep you got or if you had a beer the night before. It's about human interaction, the way your mind works, decision making processes, emergency management and much more.

Human interaction is extremely important because it's a major safeguard and the reason why there's (at least) two of us in the cockpit. If you have a communications block, which can occur due to age difference, attitude problems (arrogance, lack of assertiveness etc), language barriers, past history or disagreements, stress and more, you have a deteriorated state of communication in the cockpit, which is a bad thing.

Here's an example: Say you're driving somewhere you've never been and the person sitting next to you is reading the map. The map reader says you should go right, but you decide to go left anyway. The map reader is now frustrated and the next time he sees you taking a wrong turn, he keeps his mouth shut, just to see you make a fool of yourself. This is basic human behavior and in an aircraft, can be a setup for a problem, as you can imagine.

So one of the key points in CRM is to first recognize that such a block is present and then learning and using techniques to break out of those blocks. Very much psychology!

Ah I could go on and on but I see we're out of time for today!  Smile

I have studied Reason's model and the Tenerife disaster in detail in my Human Factors courses. I must say, the course is extremely boring, but I have taken a lot from it. We are just starting to train in the simulator in a 2-crew environment, and I can see now how a lot of the stuff I have learned applies in there. It's quite a change to have someone else helping you, doing the radio calls, and all that when in a 172, I have to do it all on my own.

Is fascinating to see the Human side of a person operating the total inverse, So you can realize your own fault...
I read some facts from Pilot reports, where both CO and pilot were asleep for such a long period! By the way what is the maximum amount of sleep crew can have in a long haul flight?

Now how can a person of So much responsibility drink before flying!? A pilot of such great knowledge to be able to fly an aircraft transporting passengers, do such as thing?
I always thought "tests" were made before flight to check the pilots behavior and reflexes... But I'm not sure.

Actually the tests are made after the flight!

That depends on the flight. But there are so many factors. If they've had a short layover in another timezone, maybe they came on the plane unrested.

The CAA now permits carefully controlled catnaps in the cockpit seat on longhaul. In IMHO it is way better to have a controlled nap in cruise than being exhausted during approach.

Well, it's not exactly common, but it goes to show that despite all the screening, morons will pop up anywhere. Also I think a certain organizational and national culture may contribute to laxness. Not to generalize but some nationalities are just less likely to drink before a flight.

50 years ago, things were different. Pilots were gods and unquestioned. If a senior pilot had a beer or a glass of wine no one would say anything. CRM has changed all that but it's worth remembering that that generation of pilots only recently retired.

The FAA conducts random breathalizer test but the first line of defense is fellow crewmembers. That was the problem at BA. Fellow crewmembers would say nothing.


The most "fun" part of the documentary was the experiment when a US 727 crew drank heavily in the evening, slept only 3-4 hours, then had to fly a sim. They missed the start of descent on one. Then they proceeded to screw up by the numbers during a simulated emergency. The pilot got annoyed at the F/Es slow responses (they were both pretty toasted) and was leaning out of his chair to point over the F/Es shoulders at stuff on the engine panel. They managed to land but all agree that they were far from top form.

Ah.... human factors is quickly becoming a hot issue in the U.S.

I just finished a one day seminar (way too little, but the boss is cheap!) I found it extremely interesting and VERY applicable to the maintenance side of the house. I wish fatigue (night shift work) would be addressed by the various governing bodies.

My biggest impression was of being self-aware, as to your own tendencies, which could pre-dispose you to certain mistakes. The inter-personal issues was very interesting. It is my opinion that this area would benefit everyone !!

The cynic in me says wait for the first accident "caused" by a tired maintenance tech. Blech...

As you say it would be good for anyone. I am technical sales, so I do a lot of face time with customers, in large part as support for salespersons. My boss is VERY good at human factors stuff and we have long chats about working with different people, motivation, and so forth. Being self-aware is good, having a boss who makes you self aware is stellar.
