The flag symbols at three airports serve as visual checkpoints for initial callup prior to entering which airspace?

• A. Savannah Class C airspace
• B. Dallas Class B airspace
• C. Atlanta Class C airspace
• D. Miami Class B airspace

Answer: (A)

In Class C airspace, you must establish two-way radio communication with ATC before entering, so ATC can coordinate your arrival and assign a transponder code. The flag symbols on the chart serve as visual checkpoints to cue pilots where to make that initial call to ATC as you approach from outside the airspace. The three airports with these flags are positioned to mark the entry points into Savannah’s Class C, which is why the correct airspace is Savannah Class C.

The other options point to Class B airspace around large hubs like Dallas and Miami, where entry requires ATC clearance to penetrate the Class B, but the specific flag checkpoints described are a feature used for entering Savannah’s Class C boundary.
