Possibly in a busy airspace... he may want to see where you are

after assigning your squawk code.


When coming off the Phoenix Class B transition from south to north for
landing at Scottsdale, I've been told to IDENT by the Scottsdale Class D
tower when I've already been released by the Class B controller to squawk
1200, frequency change approved, etc.

I'd say this is a case of wanting to pick me out of the clutter since
Scottsdale uses simultaneous left and right traffic for arrivals to RWY 21
and the release from Class B comes when you are already only about 7 miles
to the SW of Scottsdale.
