AEO: All Engines Operating/All engine operation(s)
OEI: One Engine Inoperative
PANS-OPS: Procedure for Air Navigation Services (ICAO document 8168)
TERPS: Terminal Instrument Procedures (FAA-USA)
The major differences between PANS-OPS and TERPS are holding speeds and circling procedures.
I don't yet know what RDS or PAMC is/are, but will look them up now.
