I’m
able to maintain 5,000 cabin altitude (my home base is 5,100) at 17,500 with
23” MAP. And I know my cabin leaks.

[LML] Minimum MP for pressurization
Hello all,
I was looking through the TSIO-550 Power
Settings Chart and noticed that it said the min MP for pressurization was
31.5".... I'm just wondering if this is true for all IVPs?
I was
up to FL170 the other day at 28.5" and the cabin was showing perhaps
7800. Should I assume that if I was running at 31.5" that the cabin
might only have been showing perhaps 5000'? The reason I ask is
because I'm thinking if we're at FL170 and the cabin is pushing 8000, then at
FL250 (or even FL210) the cabin pressure would be well over 10,000'. I
had thought it might have been because I have a leaky cabin or something....
but perhaps its because I'm being too cheap with the
fuel....
Thoughts?
