Something slightly wrong over Yorkshire

[Roland28]

I have just captured American 137 enroute from London Heathrow to Los Angeles climbing at FL350. According to ANRB, the aircraft is a Cessna 172, not a Boeing 772 as I would have expected!

What was the Mode S of the aircraft.

Could be a number of things:

- Details incorrect in RB database

- Details incorrect in GAS database and therefore autopopulated incorrectly

- Mode S box in aircraft wrongly set up and therefore sending wrong code

- C172 special with extra "go" :-)

It would appear that the aircraft is N799AN B737-223ER and it is in fact sending the wrong Mode S code AAC981.

Go to www.airframes.org and enter the mode s code AAC981 and read the comments.
