Debris found floating near where plane last seen on radar. Very unfortunate…

Just was watching the video timeline. Condolences to anyone affected by this.

Search for survivors called off. next of kin notified condolences to those families the

hard part will be not having much closure on the why -unless the aircraft is recovered off of the ocean floor

A very sad day for our community indeed.
My condolences for the next of kin and prayers for the absents. A very sad day.

Can someone comment on the audio we have heard? Is “we’re flying blind” recognized phraseology? What is normally meant by that?

A problem with North American English speakers is a tendency to use imprecise slang, even with ATC. The result is that there could be multiple meanings, none of which can be confirmed without further evidence.

Sounds like a massive electrical failure leading to loss of navaids. Descent from 24,000 to 11,000 at 4,000+ ft/min would also suggest a pressurization issue. Hard to piece this one together.

From observations on FlightRadar24 and FlightAware, their leg from Hamilton to Bermuda looked normal. Their northbound leg wasn't. They filed FL300 but leveled off at FL240. On the last legs of the flight it looked like they were having a hard time keeping on course. These are my personal observations.

I would interpret it as either in IMC without any navigation aids or in VMC with total instrument failure.

But it's a non standard transmission. Could mean anything.

Where did you hear that audio?

Yeah I think maybe they had a total electrical failure at night in IMC over the water. I'm not familiar with the G100 but Google says it has 2 gens, 2 batteries and some of the aircraft have APUs but it's an option. No RAT on the G100.

I looked it up and the FSI manual says max altitude for APU start is 20,000 feet (https://www.scribd.com/document/9047425 ... anual-2022 on page 113)

That flight path on Flightaware looks suspect, and it's of note that they lost contact with the aircraft as it was entering an area of precipitation. You can see it on Flightaware. It doesn't look like a storm, but IMC is IMC.

All this coupled with ATC asking them to confirm that they were coming in blind along with their weak radio signal points to something going wrong with their power supply at a really bad point in their flight.

How were they talking to ATC with a total electrical failure? The aircraft also has a standby attitude indicator with its own emergency battery.

Bottom line, clueless people are making wildass guesses without knowing the reason.

You might notice that despite having so many posts on this forum, you hear little comment from me in these accidents about what happened. Why? Because I have no idea what happened(just like pretty much everyone else). But in the days and weeks after an accident, all kinds of uninformed speculation happens. Then, a long time afterward, a final report will come out. At some point, long after the accident, I will read the report and give detailed info on how the accident could have been prevented and more often than not, I will be lucky to see one further comment by the same people who were chattering away with uninformed speculation.

Sorry I meant dual gen failure. I think their batteries lasted a while and then failed too. We shall see. I'm just a guy and not a TSB investigator but that's my hunch.

[oldncold]

To find the root cause they will need the cvr and flt data recorder (if equipped ). That should be the least that be done so families can get some closure .

Next this was a twin biz jet having a dual eletrical systems . Failure is possible , but remote. losing one would increase the load on the other. in a medivac config that may be a tough call to load shed with a critical care patient needing the power for life support medical gear.

All aircraft have quirks in electrical systems design ( though Im not g100 type rated ) jet current // one may be that: one generator failure combined with a failed gcu/hed / or current limiter in the right combination would prevent the power getting across to the battery
resilting is avionics dropping of first then battery die now you are truly in the black.

Continuing >the next tack is human factors were they having issue with electrical / one gen issues on the trip down to bermuda

decided to mel ( if approved list ) mel and return to canada on one then the second failed?

Fuel is stupid expensive 4.75 usa d liter in bermuda these days min fuel ran into stronger than forcast upper winds

Did company culture /mgt play a factor in the pdm process

my point is not to point finger but to get the data off the ocean floor before becon stops so that factual info can detetmine and provide closure to next of kin

[Daniel Cooper]

The Gulfstream G100 uses an independent standby attitude indicator to provide pitch and roll reference if the primary EFIS or main electrical power fails.
Maybe we need to take the flying blind comment literally. Electrical issue led to smoke in the cockpit and they couldn't see anymore. It's a dramatic thing for a pilot to say outside of a Hollywood movie unless they meant actually blind.
