Which sequence is used for TBAST before entering Whiting Class-C airspace?

• A. TAWS/Traffic Audio, Base, ATIS, Squawk, Tower. Prior to entering Whiting Class-C airspace.
• B. TAWS/Traffic Audio, Base, ATIS, Squawk, Tower. Upon entering Whiting Class-C airspace.
• C. TAWS/Traffic Audio, Base, Approach, ATIS, Squawk, Tower. Prior to entering Whiting Class-C airspace.
• D. TAWS/Traffic Audio, Base, ATIS, Squawk, Tower. After entering Whiting Class-C airspace.

Answer: (A)

Before entering Whiting Class-C airspace, you must be set up and cleared with ATC while you maintain awareness of other traffic. The sequence starts with TAWS/Traffic Audio to monitor for conflicting aircraft and terrain. Then you coordinate with the appropriate ATC facility (Base) to establish contact and obtain entry information. Next, you pull the latest ATIS to learn the current weather and altimeter settings. With that in hand, you assign and configure the transponder code (Squawk) as directed by ATC. Finally, you contact the controlling tower to obtain the clearance to enter the Class-C airspace. This order ensures you’re aware of traffic, properly coordinated, weather-informed, coded in, and cleared before crossing the boundary. The other options mix in the wrong controller or place the steps after or upon entry, which wouldn’t satisfy the required pre-entry procedure.
