Decision

How do you get Decision Height? I'm looking at an IFR plate and I can't find it, is there some kind of general knowledge? (like always 1,000 MSL?)

1000msl will have you flying underground at many airports 

( I'm sure you mean 100agl   ;)  )

ANYway.. decision height (DH), and minimum descent altitude (MDA), are variables that vary by approach type, and airport's minimums.

Post the plate of your choice, and we'll walk through it.

Yeah thats what I meant, sorry.



Sorry it's a little small.

Here are the minimums:

OK.. everything you need, is at the bottom of the plate..

For an ILS, your DH is: 3482msl

Keep in mind though that those MDA's and DH's can change. I don't mean like, over time, they will change, because that's true too, but operating in cold weather conditions will change your IFR minimum altitudes. If you stay in Texas your whole aviation career, you may never experience it. But if you travel further North, where people experience sub-zero ground temperatures, then you have to, HAVE TO, do cold weather corrections to your IFR minimum altitudes. If you don't, you could end up in the ground.
