Pattern Altitude
What do y'all consider an high altitude airport? Being a flat lander that is looking to venture further out I am starting to look at destinations that are 1000-2100msl. Would those be considered high alt?
It probably depends somewhat on your purpose for asking the question. For example, are you trying to decide when you need to lean the mixture for takeoff?
By the way, the density altitude is more important than the MSL altitude.
Sorry----yep, mixture settings are my biggest concern. Its showing to be -14c tomorrow so I imagine the DA will be lower than field elevation.
...It's not just about leaning for takeoff.
Thanks. You pick up a few things flying and instructing in Colorado. :wink2:Good point.

True, but I don't think any of us are trying to takeoff or land on the peaks.Well, they DO teach us about altitude's effects on aircraft performance here in California, whose highest point is higher than Colorado's highest point. :wink2:
You are, of course, correct. I recall learning making adjustments for density altitude in a 152 at a 243 msl altitude airport in Connecticut when I was a newly-minted private pilot.Sheesh... Really???
Density altitude will matter differently in every type, and then depending upon weight. To give a one figure fits all is silly. Some have suggested an altitude. Ridiculous. In YOUR airplane that may be a non event, OR, It may be a huge event well before that altitude. Know your airplane. If there is ever any doubt simply run the numbers. Your numbers are different than the guy next to you in the FBO.
Although we do the process differently, we check every takeoff and every landing. Have done so for the past 20 years in 135/121 flying.

Very true...but the discussion is about airports. Even the backcountry strips in Coolorado are higher.

Not every CA airport is at sea level. There are several in the Sierra that require mountain techniques, some of them with not-so-long runways. There are quite a few that require moderate DA techniques in summer.
My high altitude checkout in CA, while I was still getting my private, was to South Lake Tahoe and some other airports I don't remember. My flying club was very concerned about mountain flying because they had a fatal on Kearsarge Pass a few months before I started taking lessons there.Lee Vining comes to mind.
Mammoth Yosemite and South Lake Tahoe can be interesting even with their long runways.

Which club did you learn at?

The survivor wrote a book, there was a made for TV movie, and weirdly, the LA Times wrote an article about it as late as 2006.

So do I. Oakland had an on-field FSS. I even remember the teletype machines...Ha...
That was a LONG time ago... Even I remember walking into a FSS and getting a briefing...

That was it. I think I also have the book somewhere in my house.I remember watching that movie!

I actually think about that movie anytime I'm flying around/over tall rocks.
You are, of course, correct. I recall learning making adjustments for density altitude in a 152 at a 243 msl altitude airport in Connecticut when I was a newly-minted private pilot.
OTOH, the question invites altitude answers.
