If so the DC-9 was much louder. Was because I never recalled anything weird on a 717.

hobbesmaster posted:CRJ? I thought all of United’s mainline had IFE, even if it’s pretty old. For example the old directTV system on their now 20+ year old 737 NGs aren’t bad. Looks like it was an Embraer E170. The return Air Canada flight was on an E175 and those did have IFE and decent seats. Considering those specific flight are operated by Republic Express/United Express, I guess those planes don't get IFE? If you as an airline want to cheap out, that's one way to do it especially on short flights like EWR-YYZ which is about 1h 45m. Edward IV fucked around with this message at 05:11 on May 19, 2024 |

The sound is because the either the green or yellow system is pressurized and the PTU is trying to equalize the pressure ( I may be wrong about this too. This may be me trying to get someone to correct me if I am)

Jonny Nox posted:I was wrong originally. The sound is because the either the green or yellow system is pressurized and the PTU is trying to equalize the pressure ( I may be wrong about this too. This may be me trying to get someone to correct me if I am) I read a writeup and this sounds right. Three hydraulic circuits total, green yellow and blue. Green and yellow are each powered by one of the two engines, and have the PTU as a backup power source. Blue is powered by the electrical bus (generators geared to the engines), and backup (in the event of dual engine/gearbox/generator failure) is the RAT. The PTU provides power crossfeed between green and yellow without hydraulic fluid crossfeed. A PTU impeller driven by green can turn a pump which pressurizes yellow, and vice versa. Whenever one side dips more than 500psi below the nominal 3000psi, the appropriate half of the PTU kicks in until the low circuit gets back to 3000psi. The sawing/barking noise is this control mechanism repeatedly turning an impeller/pump pair on and off, just like a simple thermostat regulating a room's temperature by switching an electrical baseboard heater on or off. As described the PTU might sound like emergency equipment only, but it's heard during normal operations because engine startup is normally done in sequence, not both at the same time. Additionally many airlines like to taxi on only one engine to save fuel, so you might hear the PTU all the way up to and during the takeoff run, sometimes even after getting airborne.

Saw the Blue Angels movie in IMAX the other day with my old man. Standard military-industrial propaganda but it is quite well shot. Some of the aerial shots are breathtaking. Nothing too deep or insightful about the Blue Angels themselves and a distinct lack of coverage of the solo pilots in my opinion but I enjoyed it. Seeing behind the scenes of the pre-season training was really neat, in particular the scenes showing the new pilots struggling during centrifuge training without a g suit. Unfortunately it's out of IMAX theaters now but you can catch it on Amazon Prime. 7(g's)/10.

I would have had the rendering correctly change the shape of the shadow on the ground as the CGI drone banked. And maybe have the grass move a bit as the props spun up.
