Droopy, exactley as I was taught it, but just to add a bit more detail:
T ype
R oute (departure, destination and any relevant waypoints in between)
P osition
A ltitude (or Height, or Flight Level ands QNH if relevant)
C onditions (IFR/VFR)
E stimate (time and position at that time
R equest (FIS/RIS/RAS/MATZ/Zone Transit etc)
As an aside, on a PTLPT (Position, TIme, Level, Next Position and Time) you give time at current position in case your watch is different to the controlers etc, but I was not taught to give time at current position in TRPACER, even though you are giving time at next - is this just an anomially that has stuck or should Position in TRPACER include time?
Cheers
