Air Canada Does Search & Rescue - 270 Scanners On Board

[a2capt]

They were ready to land in Australia, at the end of a 14-hour international flight, when the 270 passengers of an Air Canada flight were suddenly thrown into a high-seas search-and-rescue operation.

Flight AC033 diverted after pilot Andrew Robertson got a call from the Australian Maritime Safety Authority on Tuesday to help search for a yachtsman who had sailed from Sydney two weeks earlier.

"If we have the fuel, could we investigate an emergency beacon that had just gone off," came the question from maritime officials, Robertson told CNN Canadian affiliate CBC News.

Down below, Glenn Ey of Queensland, Australia, was being tossed about in his crippled 36-foot yacht -- out of fuel and with a broken mast after a storm.

"I thought I had a very good chance of getting back to Sydney without assistance," Ey said after nine days adrift. "I couldn't see any evidence of Sydney, and I had no idea of my exact position, and it was at that point I set off the emergency position indicator radio beacon."

The search began as the Boeing 777, on its way from Vancouver, dropped from 37,000 feet to 4,000 feet. Robertson asked the passengers and crew to train their eyes on the choppy waters below.

"I think everyone's heart started beating a little bit faster," said Jill Brown, a Canadian singer, who was making the trip to Sydney for a concert. "They said ... we'd really appreciate it if everyone could look out their windows, and if anyone has any binoculars that could help us identify this yacht, that would be really helpful."

It didn't take too long to find Ey as passengers and crew scanned the waters below.

"We're doing this big sweeping right turn and almost immediately they said, 'Oh, we see something,' " Robertson said. "We were totally ecstatic."

Total from time from activation of the emergency beacon until he was found by the Air Canada flight: about 25 minutes.

"You know, we cheered and we applauded and I think we all kind of felt a sense of pride," Brown said.

A merchant vessel helped the yacht until the New South Wales water police arrived from Sydney late Wednesday, about 270 nautical miles off the coast.

Can you imagine the SQTR's? .. if there was an SET qualified individual on board?

I saw that - were I a passenger, I'd be filing a complaint somewhere:

A: My time, the plane was already late and this made it even later.

B: More important, my safety - taking a commercial jet down under 4000 ft over water?  Seriously, what were they thinking?

"Seemed like a good idea at the time..."

Way to go Canadians, proof again that banning contingency fees is in the self-interest of any healthy society!

So, what?  They're over the Pacific.  Do you think at 37,000+ ft they have any better shot at reaching land?!   Don't be silly.  There was no significant risk to anyone's safety.  Have you ever been on an overseas flight?  The passengers probably welcomed a break from the monotony.

Good on this crew and the passengers.  More importantly, they actually found their target.  Sadly, this puts their batting average well above ours.

Um, yes?

An engine failure or other mechanical problem at 4k feet is going to to be a lot more "exciting" a lot faster then at 37,000.
This is a typical "ask for forgiveness situation" - the results were positive, so then it must be "OK".  If that plane went into the
water doing the same thing, everyone would be yelling how dumb this was.

Uh, no.  The yacht was reportedly 270nm off the coast.  The only difference would be in the unlikely event they had such a significant problem, the passengers would have a longer time to dwell on it from 37K.  Either way, they'd be going swimming.

[Critical AOA]

Yes, if you lose both engines you can glide much farther from 37,000' than 4000'.  The glide ratio of a 777 is somewhere in the neighborhood of 17:1.  So at 37,000', the 777 could glide for approximately 119 miles.  The article stated that the yacht was approximately 270 miles from the coast so assuming that this was the minimum distance the 777 had to travel as well means splash down even at 37,000' but at least they would have been closer to land than if it happened at 4000'.   So yes, there is an increased level of risk.

However...

The probability of losing one engine is pretty low. The MTBF of modern jet engines is pretty high.  Besides, the 777 can fly just fine on one engine.  It has to in order to qualify for ETOPS as well as basic certification.

The probability of losing both engines is quite a bit lower, in fact statistically it almost approaches zero.

The probability of losing both engines at that particular moment in time is even closer to approaching zero.

About the only real risk is that considering the time they took looking plus the increased fuel burn at the lower altitude plus perhaps a higher fuel burn in climb returning to a higher altitude after the search, they would have cut into their fuel reserves.  I am sure this was all taken into consideration and the crew did some calculations and decided that their fuel remaining was sufficient for the conditions existing at the time.  I am certain they would have bugged out of the search area long before fuel got critical.

I know if it were my knickers getting soaked that I would really appreciate the fact someone took this very modest risk.   Statistically speaking, I am certain that we assume a far greater level of risk as CAP pilots when we jump in our single engine piston powered airplane to look for someone in need... but we do it anyway.

Twin Engine Jets (AKA the Boeing 777) are required to demonstrate the ability to operate for 180 minutes (thats 3 hours) on ONE engine in order to be able to fly certain routes over the Pacific & Atlantic. 

The routes they take are based on this certification (called "ETOPS" for, off the top of my head, Extended Twin-engine OPerationS), and they're never more than 180 minutes from a suitable divert field.

Also, and I could be wrong here: A lot of aviation ops internationally have a basis in maritime law & custom.   I *believe* that this is one of those circumstances where, while it might not be *required*, it is *customary* for a vessel (aircraft or ship) to divert to render aid of some sort.

Agreed.  We're on the same page.  I was just pointing out there was no significant risk (over what they already had) but didn't get into the various details as to why.

If there was a CAP member on that aircraft, could he apply for a Find ribbon?

It had to devolve into a uniform discussion eventually.

Job well done for these pilots!

Old airline joke. I first heard it back in the 90's when the now defunct airline I worked for at the time (ATA) was doing its first ETOPS certifications.  In fact we were the first airline to get certified for 180 minute ETOPS in the 757.

Did they silence the beacon?

i was on a cruise in Alaska where the PA chimed up, and some alarm sounded that sent chills up my spine.  My wife looked at me and said "uh, that isnt the lunch bell".  The captain came on and in a hard Norweigen accent told everyone we were reversing course and would be significantly increasing speed for a fishing boat broadcasting they were rapidly taking on water.  I though I was back in the Marines when that ship turned to the point where people were leaning against walls and railings and water in the pool sloshed out!  Believe it or not a cruise ship can Haul A-- if it needs to.

We got there, rescue swimmers from the ships crew were getting suited up.  However another fishing boat was in the process of taking the crew onto their boat.  I didnt hear anyone complain.
