What is the required action after passing the CIRIS fix on the ILS approach?

• A. Immediately initiate a go-around
• B. Descend to the MDA if necessary
• C. Begin a climb to the minimum safe altitude
• D. Turn back towards the airport

Answer: (B)

After passing the CIRIS fix on the ILS approach, the appropriate action is to descend to the Minimum Descent Altitude (MDA) if necessary. The CIRIS fix is a designated waypoints on the approach, and once an aircraft has passed this point, the pilot should continue with the descent as per the approach procedure unless specific conditions dictate otherwise. Descending to the MDA allows the pilot to get closer to the required altitude for safe landing, while maintaining awareness of the surrounding terrain and obstacles. This altitude is specified in the approach plate and provides a defined limit for descending when visibility is below the required minimums for a straight-in landing. If the runway becomes visible before reaching the MDA, the pilot can then continue the approach for a landing. This systematic descent is crucial for executing an approach safely and in accordance with established procedures.
