What is the lowest altitude which Navigational fix can be crossed while climbing to meet the MEA on the next airway?

• A. Minimum Safe Altitudes (MSA)
• B. Minimum Vectoring Altitudes (MVA)
• C. Minimum Crossing Altitude (MCA)
• D. Minimum Reception Altitude (MRA)

Answer: (C)

The situation is about crossing a navigational fix at the lowest permissible altitude while climbing to meet the MEA on the next airway. The term that matches this situation is Minimum Crossing Altitude. It is published at fixes where you transition from one leg to another and represents the lowest altitude at which you may cross that fix. Crossing at or above this altitude guarantees you won’t be below the required altitude as you pass the fix and allows you to continue climbing to meet the MEA on the next segment while maintaining obstacle clearance and navigational integrity. The other altitudes are for different purposes: Minimum Safe Altitude provides obstacle clearance for a broad area around a navaid, Minimum Vectoring Altitude is the altitude ATC must use when issuing radar vectors to you to ensure obstacle clearance, and Minimum Reception Altitude is the altitude needed to reliably receive a navigation signal.
