TOPI is the abbreviation for which of the following?

• A. CAS Message Inhibiting Logic for takeoff
• B. Takeoff Warning Inhibiting Logic
• C. Collision Alert Inhibiting Logic
• D. Cabin Announcement Inhibit logic

Answer: (A)

TOPI is a logic function that suppresses certain messages from the CAS during takeoff. In flight deck systems, this inhibition keeps pilots from being overwhelmed by warnings while the aircraft is in a high-workload, fast-changing phase where many alerts could be expected or non-critical. So, TOPI specifically stands for CAS Message Inhibiting Logic for takeoff, making it the correct match. The other phrasings refer to different inhibition purposes (takeoff warnings, collision alerts, or cabin announcements) and do not describe the TOPI function.
