Hi pilots, I am new to the group and wanted to see if you guys hear
Non-standard ATC phraseology around places where you fly.
Our tower at Chander, AZ usually request us to report 2 mile base when
entering a traffic pattern. I thought the standard pattern entry was 45 to
downwind or final. If you have any non-standard phraseology or clearance,
can you please let the group know?

There is no standard entry at a towered airport. The tower will tell
you how to enter the pattern. If he asks for a report that is usually
because he doesn't have radar.
