Final, 3 green
A technical question, a comment, etc done for your own ediifcation is fine. Just as acceptable is as you say, a thanks and your gone is great. What I find annoying is a PPL who craves acknowledgement of being a pilot. Most of the time its no biggie, at times its a pain. "Why did we land downwind on such a short runway" We didn't but it was said as everyone was working their way off the plane at a level loud enough(intentional) to be heard by other pax. At other times its worse. Company provided an exampe of this not long ago in one of our training builletins. An aircraft was IMC being vectored into LAX. They got rocked a bit by a heavy ahead. Aircraft rolled some, nothing dramatic. A PPL on board took exception to the explanation on the ground from the Captain. He, a PPL without an instrument rating didn't believe the crew were following wake turbulence avoidance procedures he had been taught in his training. He wrote a scathing letter about how dangerous a situation he was put in by the crew not following procedures. He also took umbrage with the PA after landing because the Captain was lying about doing every thing properly and still encountering wake.(which is exactly correct) It was presented to us not because the crew did anything wrong but to underline differences in perception based on experience.
