2000ft isn't a mountain
? Don't start me off...
If this isn't a wind up, then it's clear to me that you were neither adequately prepared nor experienced to fly this route. The fact that even now you're confused about agl vs. amsl, MAP and CAT (and MCP) limits, and even how carb heat works, indicates you should not have been there and need some professional advice. What's the wind limit in a R22 for a solo P1 with < 300 hours? I assume you had only 25 ish hours P1 at the time? Why ask all this on here, when your instructor should be able to provide you with all the information you
need?!
