Mountain airport, non mountain airport it doesn't matter. There is no haze.


Well, how do you determine where the obstacles are below the MVA. Dig out a
sectional chart?

It's all laid out for the controller. Here at BIL we have some TV
antennas that are less than 3 miles from the airport, therefore we have
a vector SID. Everybody gets the SID, which tells you to climb at a
higher than normal rate until leaving a certain altitude. I issue you
that and I get to vector you where ever I want. Every other airport
with obstacles will have a similar procedure, does not matter if you are
in the mountains or not. If the airport is really closed in with
mountains the procedure just becomes more restrictive.

That higher-than-standard climb graident applies to three runways, and only for
about 1,000 feet. Once I reach 4,500 (onl about 1,000 agl) presumably I can climb
at only 200 feet per mile after that. Are you required to keep me within the MVA
sector that overlies the airport until I achieve the altitude of a higher MVA
sector into which you plan to take me?
