When does ATC provide terrain clearance?
- Once on RADAR vectors
- not departure instructions
- ATC never solely responsible for terrain/obs clearance

MOCA
- Minimum Obstruction Clearance Altitude
- NAV guaranteed only w/in 22nm
- Communication not guaranteed
MEA
. Minimum Enroute Alt
. Ensures Navigation, Communication, and terrain minimums
MIA
. Minimum IFR Alt
. Does not ensure Communication
