Altitude selector
Re: Altitude selector
The cabin altitude selector is a knob on the cabin pressurization section of the engineers panel. When the engines are running and the doors/windows are closed, it is set to whatever pressure you want your passengers to enjoy. Rate of change of that pressure is controlled by the meter next to it, that looks like a vertical speed indicator.ggiarda wrote:Can someone explain me what's the "altitude selector" for and how does it works?
If you want to watch it in operation, give pressurization authority to the engineer (shift 3 window) and watch what he changes while you are changing altitude.

Re: Altitude selector
I wasn't referring to the cabin altitude selector (I downloaded very interesting tutorial on that) but the altitude selector that is located under the clock in front of the captain seat.
Re: Altitude selector
Ah, sorry. This is the "decision altitude" selector. The aircraft is equipped with ground proximity detection, and this is the setting for the altitude at which the alert lights operate. In order for it to work correctly, the radio altitude gauge (at the top of the same column) on the pilot's and co-pilot's sides must both be turned on, then set alert height in feet on the gauge below the clock. Default setting is 200 feet above ground. As you descend through that altitude, the lights will go from "above" through "decision height" to "below."ggiarda wrote:I wasn't referring to the cabin altitude selector (I downloaded very interesting tutorial on that) but the altitude selector that is located under the clock in front of the captain seat.
Hope this helps.
