Shuttle Drag Chute

Just curious if it was just me or did it seem the drag chute deployment
was late today. I thought I had read somewhere that the drag chute was
not only to help slow the shuttle, but it was also to help hold the nose
high for longer so it could be eased down with without it hitting the
pavement so hard. The drag chute didn't deploy today until the nose gear
was all the way down on the pavement.

James,

Part of the reason may have been the crosswind. I heard a call for a
late drag chute because of a crosswind procedure (never caught its
precise name). The idea is probably to get the nose gear down without
too much delay and increase steering authority for the remaining roll-
out.

Take care . . .

Sounds good to me. Missed that on the replays, thanks for the answer! I
am just very glad everyone is back in one piece.

They called up a Development Test Objective for crosswinds that called for
a late chute deploy.

Did you not listen to the audio? They were specifically given permission for
late chute long before they touched down.Why? My guess is cross winds.

Brian - Consider he may have been watching on some network with a
commentator and "expert" who cannot help flapping their mouths during
comms. That's why I put up with NASA TV on the web. . . with all of
its issues . . . unless CSPAN is covering. Where i live now there is
no NASA channel on the cable line up.

take care . . .

Well, I get annoyed at the nasa chatterboxes too, some are fine, but others
will just cut in and tell you stuff at the more stupid times.

There is one guy who sounds like he is constantly in a drugged state.

I listen on the web, to the sound of the tv in Win media, as its the best
sounding feed, The real feed is usually screwed up, overloaded and on one
channel only for hours before someone notices and puts it right. This is
odd, as the media channel real feed is pretty stable, but the media channel
win is low rate so who knows what is going on.

yes it was crosswinds I heard a call for late chute deploy as well as others
who heard that who have posted that here. And yes real audio stream
sucks...sometimes I have trouble with the winmedia player from the site as
well as loading any nasa.gov website lately for some reason. Anyone got a
clue as to why that might be. it really bothers me because my other browsers
work fine but IE usually wont let me go to any nasa.gov site or if it does i
have trouble playing the streaming media especially the live stuff.

Well I finally got to watch the landing with the Nasa announcer, and yes
indeed I did hear the ok for late chute deploy ddue to the crosswinds. I
think the original clip I watched was silent thus I missed that call.
Thanks for the answers everyone, it was much appreciated.

FRom The Ascent, Entry, Landing Flight Procedure Manual:



Drag Chute Deploy
Nominal chute deploy by definition (assuming WOW) is 195 KEAS. Early
chute deploy is after main gear
touchdown and before nominal chute deploy. Late chute deploy is after
weight on nose gear. Emergency chute
deploy indicates the chute should not be deployed unless the Commander
determines it is required.
If the drag chute aggravates lateral directional controllability on
the runway, it should be jettisoned immediately.
Nominal drag chute jettison is done at 60 KGS.
