Cabin Rate Of Climb Still Zero

Recommended Posts

After updating to the latest Patch, I tried a short flight from Gatwick to Jersey in the -800WL. With both Packs and the Isolation Valve at Auto and the cruise level of FL180 set in the Pressurisation panel, the Cabin Rate of Climb Indicator remained at Zero throughout the climb. I had the impression this was fixed witth the new patch.

  • Fixed several issues involving incorrect pressurization differentials.

  • Fixed several cabin climb rate indicator issues.

Hi i used to have this almost every time . just installed sp1b and will test it tomorrow during the ARLANDA REAL OPS EVENT on IVAO. But what you're saying is already stressing me!!!!

I've flown 2 flights with the new patch and from what I've seen pressurization is working ok here.

I flew today with a cruise level of FL310 and the pressurisation system operated OK with the outflow valve modulating towards close just after takeoff and the cabin rate of climb indicator reading between 300 and 500 fpm as expected smile.pngI'll try another flight at the lower cruise level FL180, although it shouldn't make any difference.

I ain't a whizz on the pressurisation logic on the NG's, but I'm pretty sure you won't start to see a climb increase until the cabin differential gets up to aroun 8 ish, especially with low cruises like 180 and such. The NG does have some real curve balls in its pressurisation controller, with different diff. press depending on cruise alt wtc etc. For example, I'm flying from cyyc to cyeg right now with a low cruise of FL250. The elevation in Calgary's already 3500 feetish, and the cabin basic maintained that altitude. Diff press is only 7.5 psi.
