Geez, I always considered some of my fellow countrymen to be anal in matters pertaining to aviation, but this is bloody ridiculous. If the f...ing lights annoy you, don't look at them!
If it was that easy they would. But when your parked up at 90deg to an aircraft at a holding point the light shines DIRECTLY into your eyes. Looking away doesn't exactly work at that point.

Was it not the commercial dept that said it was best to have the cabin lights to dim for take-off and landing so the punters could enjoy the view or not be woken up on descent? Never mind that QF was one of the few carriers having a policy (up till then) of having the cabin lights on so as to make the a/c easier to see at night. Never mind the cabin safety advantages of having the lights on at that stage of flight! Just keep the punters happy!!!
It is my understanding that the reason the cabin lights are dimmed for take-off and landing, as they are done with Qantas, is because the cabin crew need to be able to see out in the event of an emergency before declaring their door a safe exit. Darker cabin = better ability to see what's going on outside, i.e. fire. I stand to be corrected though.

Nice one about "enjoying the view" but I don't think so.

could the lights be on during the takeoff/landing phases to inspect the wings in case of possible failure of leading edge flaps?
Just putting it out there...
Is it possible to actually inspect the wings from the flight deck?

Unless your really streching the neck with the face against the glass, only the tips of the wings can be seen from normal seated position.

Good in theory re the flaps but the lights policy as stated above is purely increasing visibility to aid in the 'see and avoid' mentality.

Unfortunately as the light procedure is published as an opertaing policy there is very little leeway to vary from its form. Just because it is current policy dreamed up as 'worlds best practice' doesnt necessarily mean it is the best procedure for all circumstances. Whether it is a benefit or more of a distraction to other operators will only be known through feedback. My suggestion should anyone be impeded or distracted by the lights that QF use- put pen to paper in a safety report.

QF at one stage was receiving a lot of customer complaints re turning the cabin lights on during descent causing pax to "wake up"..!! Especially on long haul ops. They also wanted to be able to see the "view"....
As most other airlines of the day had them off for tkof & ldg, the commercial folk were of the view that the procedure was costing the company business. And since it was the front-end pax that made the noise they took notice. The safety and operational folk of the day conceded to that commercial pressure thing and the procedure changed.

The 3 main reasons for having the cabin lights on at low level as I understand were; increases ability of CC to observe cabin when all pax seated, increases chance of seeing fumes etc during that segment of flight and makes aircraft easier to see from outside... all a matter of opinion I guess?

The argument of having the cabin lights dim/off to improve eyesight in the event of light failure is said to be a myth. I understand it has been shown that in such circumstance the time taken for the average cc to adjust is measured in seconds even when the cabin lights went from max bright to off.

Not much chance of doing that when the aircraft with the lights on is behind you at the holding point and your world becomes like daylight!! Like I said: AIRMANSHIP!!

G'day Hedge,

The present order supercedes the original which may have had the references in it, I'll try and track it down and find out.

Regards,
BH.

Hedge,

Try FAA AC120-74 Section 8.

The first attempt at new Qantas SOPs for lights reflected this document fairly closely. However, after many comments by line crew about multiple switchings required at critical times the policy was revised.

In the context of this thread the "Wing Lights" (name may vary according to aircraft type) were originally only required on lining up. The revised policy requires them all times during taxi up to 10,000ft and vice versa on descent.

Personally, when on final approach I have found the increased visibility of aircraft on/entering runways with wing lights on quite marked.

Never ceases to amaze me how pilots leave their landing lights on at night in thick cloud where night vision is completely wrecked and the distraction of the back-lighting glare must surely affect crew concentration.

Capt Fathom 12th Aug 2009 04:55

Obviously you are easily amazed !

QF wing lights
 
Annoyance, lack of awareness or plain stupidity. Can someone in the know please explain why?
Having been blinded on numerous occasions I am yet to understand the logic behind the very use of the wing lights whilst taxying.

Capt Kremin 1st Sep 2009 05:49


Annoyance, lack of awareness or plain stupidity.
Try company policy.

KTM525 1st Sep 2009 05:56

or try "worlds best practice"..:ugh:What happened to airmanship?

OneDotLow 1st Sep 2009 06:01

Without a reference....

ICAO published recommendations and this company policy is as a result of those recommendations.

Transition Layer 1st Sep 2009 06:02

Feel free to join everyone else here in expressing your disgust.

Company policy which was designed in accordance with FAA and Euro recommendations. Not much we can do!

fender 1st Sep 2009 06:10

Glad somebody brought it up. Please advise your management of the dangers to the rest of the aviation community, so you can get your SOP changed. It can be done.
TL, Spewwww.

Sykes 1st Sep 2009 06:15

Funny!
 
You opening with


Annoyance, lack of awareness or plain stupidity.
and later on...


I was merely trying to elicit a logical response,
ROFLMAO! :} :} :}

Maybe English isn't your first language. Open with an abusive and arrogant post, expect some "harsh" replies.

But you're not arrogant... :E :E

Capt Kremin 1st Sep 2009 06:23

I think the point is that the QF drivers are only following the instructions issued by the owners of their particular train set.

We got the same accusations of arrogance when we were told not to flash landing lights at other aircraft when airborne. (a relic of pre-TCAS days).

Maybe if you didn't start with a presumption of arrogance or incompetence, the replies would have been more civil in return.

C441 1st Sep 2009 06:32

Report it to an authority - not Pprune
 
If it's as bad as that use the appropriate channels to report it. Maybe then the relevant authorities may review the procedure worldwide - and possibly prevent a lot of name-calling....then again this is Pprune:rolleyes:

Incident report - second form down on the left

Fender,

Better yet....why don't you write to Peter Wilson (Chief Pilot) and you can list the dangers to the rest of the aviation community and try to get our SOPs changed.

Keg 1st Sep 2009 06:51


Who else uses them again?
Been a while since I've operated internatinally but I recall seeing the following airlines with wing lights on at various stages.

BA, Singair, Thai, Air France, Malaysian, Philippine Air Lines, Lufthansa, Cathay, Air China, China southern, China Eastern, Cathay (although that may have been a one off), etc, etc.


Please advise your management of the dangers to the rest of the aviation community, so you can get your SOP changed. It can be done.
Strewth, lucky you told us on PPRUNE that this is what we should have done. We would never have thought of that on our own. :rolleyes: :ok: As noted by others, this is supposedly the 'norm' around the world and so the standard response is that we won't be changing it unless ICAO and the euro mob change their guidance.

It'll be another three or four weeks and we'll be doing this discussion all over again.
