I am wondering when you are supposed to use these commands on unicom:
- Holding short runway xxx: I hear some people calling every time they hold short for any reason, but I only use if another aircraft is going to use that runway.
- Requesting rraffic advisory: Are you always supposed to use this, or only when the pattern is unclear?
- Is calling each leg required?
- Do you need to announce crossing runway if you land, slow down to 30, but then continue to cross another runway before exiting?
