When using V/S, I can get about the rate of descent I need thanks to the map with the arc (aka the "banana"). But if I have to get down as quickly as possible, what rate should a push of the "DSC", descent key, produce? I tried it a couple of times and it works, boy does it! I was getting a 4000 fpm rate and the monitor was shrieking "pull up, pull up". Well of course I did, but why would it give me that much? In the real 737, the Lvl Chg button never produces 4000 feet per minute. Something like half that would be more appropriate.
Is this something I can set? I'm perplexed. Where is the documentation?
