Best of luck with your operation.
Aspen is a very interesting airport to operate to/from. Most of the info others have given you is right on.
Be sure to take your time and have things set up prior the the approach...slow down and don't let Aspen Approach rush you (123.80)...ask for delay verctors if needed. DEN CTR likes to forget to hand you off about 30% of the time and this may result in you being high. If you have any questions about the WX ask the guy you are talking to what is going on (APP, TWR) and ask for PIREPS. They may be changing the ATIS to something completely different and you may or may not be able to get in depending on what it is doing.

When you go in there the first time I whould HIGHLY recommend to give an hour or so and ask the Tower guys for a tour. It will really help explain their operation and visibility markers, traffic seperation requiremnts. TCAS Alerts are a common occurance!


If possible do SIM training there...have the turbulence up and use the Anti-Ice System to get a feel for real life
As far as a missed approach and or Balk Landing...they work...from personal experience. Just make sure you are right on for the timing and you need to know the procedures down cold without hesitation. If you don't like what is going on get out of there (the sooner the better)!!!
I would also recommend you look up the G-III crash up there. You can see how things get bad real quick.
Once you get PM up and running if you have a question just ask.
