For those of us who like to track flights by aircraft type code here is the new link.
faa.gov/airports_airtraffic/ … capda.html
The FAA in their infinite wisdom decided to make the new link about twice as long and of course they couldn’t just re-route me to the new link from the old one. I had to spend the better part of two hrs to dig the new link out 
…our tax $$ at work 
5/14/07: Fixed the link.
Your link doesn’t work. 
You can look up aircraft types at flightaware.com/live/aircrafttype/ assuming at least one aircraft of that type is in the air.
Link doesn’t work. Why not just go to faa.gov/airports_airtraffic/ … lications/ and select the version (PDF or HTML) of the Contractions handbook that youlike?
…and, as reported elsewhere, to add to one of those publications, a new register has just been created in Europe with a new prefix, M- for the Isle of Man (where you ask?) Probably to be used on a tax concession basis like the VP-C and VP-B registers.
See
gov.im/dti/Aircraft/
So FA, what process needs to take place to get these tracked?
IN (UK)
Ah well…missed a “-” in the link 
Let’s try again.
faa.gov/airports_airtraffic/ … capda.html
And thanks for those other links!
