Although I've owned the Flysimware C414AW since it was released I have never undertaken a serious flight with it. Now I'm planning a longer trip at a higher altitude and I can't seem to find how to operate the pressurization system in the manual, only a picture of the lower panel with the gauges and switches identified. But how to use it? What's good practise? I assume setting a desired cabine altitude and climb rate; but how do I set the switch? 'Pressurize' or 'cabin'. And what about the pressurization air control knobs? Also, I can't find where to set the destination altitude...

I thought it was Pressurize or Dump? 

In this sort of system it doesn't have a separate dial for landing elevation, you set it on the same one you set the cruise altitude. Just before you start descent....

The switch has three steps; pressurization > cabin > depressurize. So I guess you set it to 'pressurization'? And what does the 'cabin' option do? Strange the manual doesn't explain the use of the system.

It’s really quite simple. Just turn the rotary dial to your cruise altitude during your preflight procedure. This will also show you the cabin alt that will be maintained at that cruise altitude. Then ensure that the switch is selected to Pressurise when the checklist directs it. When ready for decent just rotate the dial to read airport landing plus 500 ft. The cabin rate of climb/descent defaults to 500fpm which is fine, so you can just leave that alone. When on the ground select Depress on the switch, when directed to by the checklist.

Thanks for explaining. I found a POH on the Flysimware Discord in the meantime, which explains the operation of the system in detail.

not sure on this but if I recolect correctly from flying them in R/L 30 odd years ago that there was a 'squat switch' that that activated when weight came on the main gear - was a bit of a wake up call if you had forgotten to set the field elevation prior to descent - you only had to have it happen once to remind you of your TOD checks - was the same for 340 & 421 if I remember correctly
