Why report aircraft type?

[fc101]

Is that really an issue over there? In my 25 years working here at N90, I can't recall a single instance of an airliner coming in as one type, and turning out to be another. That's more likely to happen with one of the many general aviation aircraft we have buzzing around in VFR flight plans, but an airliner on a regularly scheduled flight plan?

Not quite the situation being describe here, but not many 747s are deliberately recorded as being Gulfstreams....

[His dudeness]

His dudeness. I know (from my own extraordinary capabilities) that air traffic controllers are superhuman but even they cannot retain the entire world civil aviation registers in their minds!!

Since I´m half superhuman (dad was an ATCO) and half superman (pilot !) I know what you are talking about....

However,

To ensure the aircraft type is as per flight plan.

, when I fly under the tail number, the odds of using the wrong type are very, very small indeed....

It certainly helps when you have an multiple aprons full of biz jets and you're trying to locate the one speaking to you and they don't know their stand number!

I always know my stand number! (If not, its my colleagues mistake....)

I believe it's not always for the benefit of ATC but it helps other aircraft as well

Also conditional clearances...."Line up after the landing (a/c type)".....seen it a number of times down the years when the inbound is not the type on the strip.
