I have been flying our Mooney M20J for about 12 years, always in the East. Next June, I hope to fly to Colorado Springs. While there, I hope to take a mountain flying course in our plane. Yesterday, I consulted the performance tables in our POH. The tables give no data above pressure altitude 8,000. That seems to imply that the plane will not climb above that pressure altitude sufficient for takeoff. Can that be correct? Does anyone have high altitude experience with a 201 that will give me a little guideance? Maybe this sea-level pilot has just forgotten how to work those charts.
