"Fully ready"
"Charlie charlie"
Ending every readback with the word "Confirm"? Yes, we know you like to make in impact on the airwaves, but if you have to confirm every clearance then perhaps you need more work on your listening watch or be ready to write things down the first time.
Any queries in a radar environment under positive control of ATC that relates to "track miles". Just do what you're told, fly your aircraft, check your TCAS to see where you fit into the sequence if you're that interested, and shut up.
In a radar environment, after they've been givin a final intercept turn and "Cleared for the ILS Rwy XX approach" , pilots reporting they're "established on the localizer" (which usually forces the controller to respond with an equally useless "continue approach"), or even worse, querying if they're cleared to "descend on the glide". Yes, being "cleared for the ILS approach" means you are also cleared to intercept and descend on the glideslope, and you DON'T have to report established in a radar environment unless asked by ATC to "report established". THey can see you turning to establish yourself. Seeing you doing things is the whole point of having ATC radar.
Controllers who you think may have cleared you to fly direct to a waypoint, but don't use the word "direct", forcing us to question if that's what they really meant.
Controllers who have a runway exit plan for you after touchdown, but keep it as a closely-guarded secret until on the landing roll.
