April 6, 201214 yr Next to the Isolation Valves there are two Switches. "L PACK" & "R PACK" is it safe turning them off after I started the engines? Do I really need those Packs on the entire flight? they are very noisy must I say. Joel Strikovsky
April 6, 201214 yr Hi! They are needed for pressurization and aircondition. So, you'll need those PACKs on the entire flight. _____________________________ Peter Burghardt (LOWW)
April 6, 201214 yr In FSX are useless, in the real one are something vital if you want to climb over 14000ft (and also below as they will replace old air with new one). Basically they are devices that uses hot ait from engine or apu bleeds, cool it (as required) and pump it into the cabin. The pressurization system controls an outflow valve that will exhaust excedance air. If you require extra power from the engines, you could turn them off for the take off. Remember to put them back to ON Regards Andrea Daviero
April 6, 201214 yr The cabin altitude warning horn which will eventually sound if you don't use the packs above 10,000 feet is much louder!

That sound, to me, is probably more annoying than the lady saying "Autopilot" in the MD-11 (That's if you don't know how to turn it off :Just Kidding:) Chris Ferguson PC Specs(Rebuilt 1/11/19): i7-9700K - Non-OC'd, EVGA RTX 2080ti, G.Skillz 16GB Ram 3000mhz, EVGA SuperNOVA 1000w PSU, Cooler Master ML360R, ASRock Phantom Gaming 4 MoBo, 2x 2TB HDD, 1x 1TB Samsung EVO SSD, 1x 220GB WD SSD

April 7, 201214 yr You could. But if it's a silent cockpit your after, you should just turn off the engines. ;) It's not entirely silent till you turn off the battery and standby power too :P ----------- Trent Hopkinson Trent Hopkinson, 2015 Crewmember of www.mangrove.com.au WorldFlight sim Youtube channel www.youtube.com/user/musicalaviator
April 7, 201214 yr It's not entirely silent till you turn off the battery and standby power too :P ----------- Trent Hopkinson no its still not silent since you still be hearing your heartbeat since you got no engines and going down in flames.

April 7, 201214 yr You can also just disable those specific sounds in the sound folder, so you still have them on but you can hear again :-) Jay
