What 3rd document must be carried ?
A: photo id. New in 2004 FARs.
Whats you max permitted flying as a comm pilot ?
A: 8 hours in day. Rest is 10 hours.
Some other misc stuff about part 121 etc .... which was weird.
Mainly was about maintenance stuff, MELs etc, holding out, commercial pilot permitted ops, weather, flight planning, airplane systems.
Know the ASA Commercial Oral guide well, and your airplane systems, and be able to recite all the V speeds, memory procedures, etc. and it should be a pretty smooth oral.
Each examiner has their favourite subjects so recommend you ask around so you know the hot button stuff.
