I restore watches that have backs, bezels, pushers and crowns all tested to 100M, why can aircraft kit that costs bazillions be so leaky?
Those expensive Apple laptops also funnel liquids right to the motherboard.

The film is worth a bit of a watch for the airplane they used as a backdrop. Quite the Frankenstein assembly.

An interesting engine mount choice, for sure.

I've been getting pilot bulletins about avoiding liquid spills for at least two decades now. We are all trained not to pass drinks over the center console but inevitably somebody parks his Starbucks on comm panel while building his nest and knocks it over. And over the years the cup holders are often too small or too large for the latest fashion in beverage containers e.g. the vacuum sports mugs.

Actually it's a pretty good B-movie in my opinion, definitely worth a watch. Ernie Gann disowned the film since it had little to do with his iconic book of the same title. However, he later lamented that this move to preserve artistic integrity cost him a lot of money in residual royalties as the film played on television for decades in syndication.

In the movie the smoking gun is found at the crash site, a paper coffee cup in the wreckage of the cockpit.




The full movie is here:

Yep it comes full circle.
when I a young un in nappies we progress from boob to bottle to a teacher beaker with lid on.
grew up a little, lid and nappies come off.
grow a little more and want boob.
become a responsible adult with a professional job, lid goes back on drinks.
looking forward to the nappies.......

Spilling Liquids on the Aisle Stand

I don't know why the recent thread on this was locked, although it did take a bit of a diversion ...

It was locked before I had a chance to post that I suspect the reason for the rumored discussions between operators and Airbus was an event earlier in the week of a Delta A350 diverting into Fairbanks following an unrestartable uncommanded engine shutdown on an Airbus A350 after liquid was spilled on the aisle stand.

You mustn't spread such professional pilot rumors on PPRuNe!

I post rarely enough here that I'm not sure if that's sarcasm or if I busted a rule. Please let me know if I violated some rule or norm.

The flight was DL159 on Tuesday. Flight aware shows the single engine diversion was 3 hours long.

I was joking, your post is most welcome by the few of us here who are professional pilots!

Thanks for clarifying.

That diversion was notable as one of the longer single engine diversions in ETOPS history. Although we've had 180 minute operations going on since the late 80s and ETOPS beyond 180 for more than a decade, there have been very few actual single engine diversions over two hours in airline service.

If you can shutdown an engine by spilling coffee on the center pedestal the basic design is weak

Then the basic design of many things is weak. Try spilling water over your computer, radio, tv. There are things which have to be handled with care. You canít design for everything, even in this lawyer dominated age.

The cockpit has always been sensitive to liquid mishandling. I once had a ride in a DC8 across the Sahara to learn the intricacies of an inertial nav setup we were getting on another type.

The copilot spilled a very little orange juice and immediately two com VHF boxes and two ADF boxes went dead. The FE spent a long time unscrewing and drying out the boxes before we got one com and one ADF back.

Like throwing pennies into the engines, it is something you have to avoid by knowledge. On another airline, cabin crew were trained to pass drinks around the outside of pilots but even there, there were electrical and electronic items to be avoided.

Nope, the DL A350 didnít have an uncommanded engine shutdown, nor was it a result of a liquid spill. Aircraft was repositioned next day back to the lower 48, and the following day back on a long haul ETDO flight to Asia.

Righto, Iíll bite. If not this, what happened? Something unusual/interesting has been darkly hinted at on avherald.

True, but modern car manufacturers manage it. If, like me, you have spent time working on cars, you will notice that nowadays, electrical connectors in the engine bay and suspension components are quite securely sealed against water ingress, with rubber or nitrile O ring seals*.

Considering the price of an ACP or RMP, (aircraft communication boxes), it would not seem too much to ask for a similar level of protection against liquids. It is harder though, to seal a shaft that needs to turn, such as a volume control, and Comm boxes have lots of volume controls !

......On another airline, cabin crew were trained to pass drinks around the outside of pilots .
Yep, TCX had this rule. We still went bust though..................



*Unlike the awful days of Lucas car electrics......shudder.

At least the Airbus cockpit keyboards are officially liquid and coffee (conducting sugar) resistant.
