Thats true. Boeing recommends a 3 minute cooldown period after using engine power higher than idle reverse thrust to settle cowl heat soak back temperatures.. in other words, to thermally stablise the engines and prolong their life. However most of the time, it takes 3 minutes at idle power to taxi to the gate, and Boeing says that this is permissible towards the 3 minutes.

There is also a delay before we switch off the rotating beacon, the flashing red light on top and the bottom of the plane. Most airlines wait until the engines are below 10% N1 (the big fan infront of the engine) before switching off the beacon so ground handlers can then approach the aircraft.

Then there is sometimes the inexperienced airbridge driver that attempts to join you in the flight deck, by driving his own entry into the flight deck with the airbridge. I've done landings smoother than some airbridge driver dockings... airbridges are driven by the ground handlers at each port. And they aren't the easiest to drive.... And the ground handlers aren't necessarily the airline that you travel with, but quite often 3rd party contractors.

Brisbane has a dicky gate that is suspectible to water damage and will cut out now and then, (Gate 77) Last time that happened to us, we ended up getting the airstairs and people had to walk across the tarmac to enter the apron.. but was better than waiting for them to try and send a engineer out to try and fix the bridge.

Sydney can be really bad, especially if you arrive early during a busy period, as quite often if you arrive early, the previous aircraft will still be on the gate, requiring that you wait for the gate to become free before taxiing and a P.A for everyone to please remain seated till we reach the gate.
