Ouch... that's a new one to me. I didn't even realize the airlines are using HUD's.
Slightly off topic, but this audio tape may be an example (other communications were clipped out so don't know for sure).
I've noticed a lot of fast talking coms from both pilots and ATC in recent years. I grew up in NY, so I'm familiar with deciphering fast talk, and understand when the frequency is jammed (i.e., during push times) non-stop and often non-standard fast talk is common.
Having to request ATC to say it again to assure accuracy and mutual understanding negates the need to fast talk in the first place, while also introducing an increased chance misunderstandings.
Recently experienced a fast-talking tower controller that spoke so fast I had to follow up two times requesting clarifications. I was the only active plane on or anywhere in proximity to the airport, and ground and tower frequencies were dead... as if this tower operator's style of streaming out a list of information and instructions in the shortest amount of time is a badge of competency and achievement.
Maybe just too much caffeine?
