An 11,000 fpm descent is achievable, and much more is possible
Thrust levers to idle
Autopilot-disengage
Landing gear and spoilers (dive brakes) deployed
>70 degree bank
Maintain 350 knots or MMO .82
And, put your mask on because you'll lose the cabin pressure .And you may lose an engine so turn the igniters ON.
It's not otherworldly - just an E ticket ride.

Lol nice one. Intentional configuration like that would be otherworldly, wouldn't it?

Have there been any reports from passengers on the nearby planes (UAE409/LNI626) that flew through the same weather pattern at the same time. Any comment on how rough their ride was?

a reply to: spikeruk

All I could read was that they passed through safely without incident. None of the passengers have seemed to have said anything was amiss, according to MSM of course.

a reply to: Nochzwei

No, just wet turbulence within 40nm.

a reply to: F4guy

You don't even need to do all that work- just stall the airplane and don't recover. AF 447 impacted the ground at 11,000 fpm.

They have officially named 2014 the safest year in air travel by a tiny margin. The accident rate was one fatal accident per 2.38 million flights. Previously it was 2012 at one per 2.37 million. MH17 was not included in the list as it was shot down, and considered a war time risk loss, not an accident.

In my outfit it's called an emergency descent, and is a memory item.

Oxygen masks
Spoilers
Thrustlevers (yes in that order)
Turn off airway
Config/reconfig autopilot
Talk to ATC/other traffic

I've had to do that a couple of times in my career and it would get us 6000-10000 fpm descent.
Probably more if we dropped the gear, but MD/Boeing never supported that.

Airspeed, Attitude, IFR conditions, day/night, thunderstorm?

In a Boeing Level Change and current speed.
In IFR conditions in an thunderstorm thats another story.
Strong up or downdrafts, in an updraft a guy watching the radar might see you climbing at 8000ft/min, while you're not climbing at all, the air around you is climbing.

That is almost exactly the A320 memory item checklist for an emergency descent because of a cabin pressure loss. We practice these in the simulator and, depending on the check pilot, do one on the checkride.

let's just be glad that bad spelling skills does not equate to bad flight abilities

A second US Navy ship, the USS Fort Worth, and a P-8 aircraft are now on the way to assist with the search.

a reply to: justwanttofly

Fort Worth is a good platform for SAR, and I figured it was just a matter of time before a Poseidon showed up.

ETA: Looks like she's in the area now on a 16 month Asia tour (arrived in Singapore in December 2014, returns home March 2016), but they haven't had a formal request for her to join. She'll join the search as soon as they have the request.

USS Fort Worth

a reply to: Zaphod58

She apparently arrived in Singapore on the 29th. Not bad timing.

I was surprised when the Poseidon wasn't requested/sent initially.

a reply to: justwanttofly

Yeah, I expected that to be one of the first aircraft sent to the area when I heard about it.

Just saw this come across...


In ~100 feet deep water RT @ChannelNewsAsia: BREAKING: Main wreckage of #AirAsia #QZ8501 found, says BASARNAS chief channelnewsasia.com/news/asiapacif…

a reply to: Zaphod58

Apart for the P-8 having better sensors and telemetry , i still think the P-3 may be superior in a SAR role in inclement weather. Superior low level flight performance and the turboprops are a plus here. as there is a lot of metal spinning around which adds to gyroscopic stability.

Strong up or downdrafts, in an updraft a guy watching the radar might see you climbing at 8000ft/min, while you're not climbing at all, the air around you is climbing.

But in a simulator when you deploy the air brakes, you do have to put the nose down to maintain the desired airspeed.
Yes in a sustained updraft the plane will climb even with level attitude and current airspeed

I have this feeling the black box was found at least a day or go (maybe longer). It does send a signal. Yes, I'm sure it's possible that they haven't found it yet. I would think the governments would want one or two days start to analyze the tapes before they are released to the public.

Anyway, as a side note, I was reading about the history of the Java sea. Apparently, there was a huge Naval battle during WWII and many ships sank. Bad, bad energy in that area (if you believe in that stuff).

a reply to: Daughter2

If they found it already we would've definitely heard about it. It's the holy grail of plane crashes. They wouldn't have released the tapes or anything but they would've informed the media that it was found.
