I'm planning my 250 nm XC for my instrument rating and would like to
do a PAR approach at Pt. Mugu naval airfield (NTD) in CA on my way
back from San Luis Obispo. How would I file that? I will be coming
down V25, should I expect the IAF to be VTU? Is there any way to
indicate in the flight plan that I would like a practice approach
there on my way back to Hawthorne? Perhaps "PRAC APPCH NTD" in the
remarks section?

As someone else indicated, calling ahead of time is a good idea, not only
for post-9/11 consideration, but also to make sure that they have the
staffing necessary for the PAR approach. I do ASR approaches into civilian
airports, and I always call ahead on the phone to make sure they will be
able to accomodate the request.
