To presurize or not to presurize

[hharney]

The pressurization system would be the last thing I would worry about on a P model. Very simple system but one must understand the operation. Once you understand it you will be able to troubleshoot most issues as the user. The P model is a special case and there are a lot of complexities that Cessna glued and taped together. Don't get me wrong, the airplane works well when it works right but it's also a mission based aircraft. It's not a Sunday hamburger, look at the scenery type machine. It's heavy, tight inside with limited ventilation and the cowls are packed to the gills with all the components required to "CONVERT" a non-pressurized airplane to a different catagory. The airplane was not "clean sheet designed" to be pressurized, not unlike other birds out there. If you want to go high and long distance then the P model may be the one but if you are looking to fly 200 miles or less a lot then the P model may not be the machine. Don't buy it for that ONE trip per year that you utilize the expensive extra features. The normal aspirated Skymaster will provide 99% of all the needs you may have and lot easier too.
