What does TBAST stand for, and when is it accomplished?

• A. TAWS/Traffic Audio, Base, ATIS, Squawk, Tower; Prior to entering Whiting Class-C airspace
• B. TAWS/Traffic Advisory, Base, ATIS, Squawk; Upon departure
• C. Traffic Broadcast and Surveillance; Before takeoff
• D. Tower, Base, ATIS, Squawk, TAWS; During landing

Answer: (A)

TBAST is the pre-entry sequence used for joining Whiting Field’s Class-C airspace. The letters stand for Traffic, Base, ATIS, Squawk, Tower. - Traffic: stay aware of nearby aircraft, using TAWS or traffic advisories to maintain situational awareness before you enter. - Base: contact the appropriate ATC facility to coordinate entry (a base/entry call or equivalent clearance). - ATIS: obtain the latest weather and airport information so you know winds, altimeter, and any advisories. - Squawk: set the assigned transponder code for radar identification and altitude reporting. - Tower: establish two-way comms with the tower and follow its instructions as you approach and enter the airspace. This sequence is completed prior to entering the Whiting Class-C airspace to ensure proper communication, weather information, and radar identification as you join the airspace.
