United Flight 1727 Audio Severe Turbulence
« on: April 04, 2012, 12:49:07 PM »
United Flight 1727 was flying from Tampa, Florida, to Houston with 151 people on board when the incident occurred, which prompted medical crews to meet the airplane when it landed at 7:30 a.m. CT (8:30 a.m. ET).

Any Audio of this?

I was on this flight and would love to hear the audio.  We dropped 6,000 feet in a matter of seconds. Anyone that wasn't buckled found themselves against the ceiling.  No warning from the pilots.

I did a search on the April 4th archived IAH feed, but since this feed is monitoring so many very busy frequencies, it was very hard to follow UAL1727's progress. All I could hear were some vectors and a brief explanation to tower that the flight attendants didn't know how many were injured.

You didn't lose 6,000' in a matter of seconds. I would love to hear how came up with this though!  And no civil aviation pilot is going to warn you of severe turbulence as no civil aviation pilot is knowingly going fly through an area of severe turbulence.

It was in a matter of 60 seconds. In one minute, they went from 38,000 ft. to 32,100 ft., so about three times as fast as the rest of their descent profile.

according to flight aware the max rate of descent during the flight was 2800 fpm. http://flightaware.com/live/flight/UAL1727/history/20120404/1030Z/KTPA/KIAH/tracklog

each line appears to represent 60 seconds of data. so they lost about 6000 ft in 120 seconds.
Yesterday I couldn't spell air traffic controller. Today I R one.

If the sample interval of the flight data tracking is 1 minute,
that only means they dropped 3000/6000/whatever ft. within that minute,
it does not mean they gradually descended during that time period.

So just saying, although its probably unlikely they dropped 6000 in a second, :roll:
this probably was quite a bumpy ride you cant see just from reading graphs with the data provided.

each line appears to represent 60 seconds of data. so they lost about 6000 ft in 120 seconds.

The FPM data FlightAware shows is taken every sixty seconds (with all of the other data points). That -2800 fpm data point was exactly at that minute, not the maximum over the minute. And if you just think about it, if they lost 6000 feet of altitude in one minute, their rate of descent needs to average -6000 fpm over that minute. That means they could have had a rate of descent greater than -6000 fpm and a rate of descent less than -6000 fpm or they could have done exactly -6000 fpm over the entire minute interval (unlikely it was exactly that).

Regardless of what the max fpm was or how much altitude they lost, in a short amount of time, due to turbulence, they still descended 6000 feet in just one minute. Looking at the entire descent profile, that is approximately three times the rest of their descent rate - that's quite a difference that the passengers would certainly notice.

LOL nice one! Everyone's busy debating how much altitude was lost no one ever answered your question. I am going to guess no :/

There is, but it's a very small amount. The feed for that area has so many active frequencies that it's hard to track the progress of just one airplane. That's not necessarily a bad thing, but you can't dig up an emergency like this and be able to follow the steps of the aircraft from the emergency declaration to touchdown.

You can find the audio of this flight on the April 4th IAH feed archive at the GMT times listed in the linked report, but I don't have time to go through it all again for the small amount of audio it will yield.
