Space Forum / Shuttle / July 2006Astronauts in the ascent
Hi, Do the astronauts push any button, flip any switch during shuttle ascent? I have looked some launch video from inside cockpit and don't know if the push something or only point at it. If do so, which ones? thanks (excuse my english) > Do the astronauts push any button, flip any switch during shuttle ascent? > I have looked some launch video from inside cockpit and don't know if the > push something or only point at it. > > If do so, which ones? Not a lot. They're basically along for the ride. The pilot's main job is during emergencies (not that there's a whole lot he/she can do during an emergency other than say "uh-oh"). During normal operations I'm only aware of one in-shuttle activity between SRB ignition and MECO: T+30s: ADI ATT switches to LVLH positions This happens right after the roll maneuver and it adjusts the attitude direction indicator. I think this is for the pilot's own benefit and has nothing to do with the flight. After MECO things start to pick up as the OMS burns happen, the umbilical doors close, the computer programs are changed from launch to orbital operations, and so forth. Disclaimer: My info is dated, things may be different in the new glass cockpits. > > Do the astronauts push any button, flip any switch during shuttle ascent? > > I have looked some launch video from inside cockpit and don't know if the [quoted text clipped - 12 lines] > direction indicator.

They have in a few cases hit switches in response to alerts, such as the engine inhibit switch on I think Eileen Collins' first flight to prevent it from shutting down and forcing an abort. > After MECO things start to pick up as the OMS burns happen, the > umbilical doors close, the computer programs are changed from launch to > orbital operations, and so forth. > > Disclaimer: My info is dated, things may be different in the new glass > cockpits. > Hi, > [quoted text clipped - 6 lines] > thanks > (excuse my english) Not unless they need to take a sh.t >Hi, > [quoted text clipped - 6 lines] >thanks >(excuse my english) > There is an Abort mode switch that CDR changes as they progress thru ascent.

Not sure if this has changed with glass cockpits though. On STS-51F, the number one SSME on Challenger shut down prematurely due to a sensor problem. An abort to orbit was declared. That required CDR Fullerton to rotate the Abort Mode switch to the ATO position and press the Abort button. From then on, l believe the pilots continued to monitor flight performance until MECO. Endeavour may have had to do the same thing in February 2000. I found one passing reference to it but I have to run to work. Try goggling abort to orbit. blue skies John >> >Hi, >> > [quoted text clipped - 15 lines] > the Abort button. From then on, l believe the pilots continued to > monitor flight performance until MECO. I remember that one, we also skipped the OMS-1 to make up the underspeed. Coasted to apogee and did the burn there. In sims we would have normally made up the underspeed with an OMS-1 burn.

They don't move the abort rotory switch unless they perform an abort. The only nominal switch throw is the switch to control the software driving the attitude indicator. One of the ADI modes has a sigularity when pointed straight up, so they launch out of this mode. Very early they move the switch to the mode needed for ascent. It is interesting to note that on an RTLS, the orbiter will fly straight up as it pitches through the vertical. The attitude indicator goes nuts for couple of seconds. We almost put a seperate attittude indicator in the cockpit to be used during ascent and entry. We ended up compromizing a bit and accepted the one that tumbles when pointed straight up. >>> >If do so, which ones? >>> > [quoted text clipped - 13 lines] > Coasted to apogee and did the burn there.

Is there the same for re-entry? Not that I've seen, but I'd be interested in seeing it as well. I'd also like to see a landing video from inside the cockpit. The only video I've seen shows the HUD for a few seconds and then cuts to an exterior view of the Shuttle. |
