When cleared to cross HOPET at 7000 feet, what action should you take at an MCA of 7400 feet?

When cleared to cross a specific waypoint, such as HOPET, at a prescribed altitude, it is crucial to understand the Minimum Crossing Altitude (MCA) associated with that waypoint. In this scenario, with an MCA of 7400 feet and a clearance to cross HOPET at 7000 feet, the action to take is to query Air Traffic Control (ATC).

Querying ATC means you are seeking clarification on whether to maintain your current altitude of 7000 feet, which is below the MCA, or if they can provide further instructions. This is essential because passing below the MCA can potentially pose safety risks and might not comply with the regulations governing altitude clearances. By querying ATC, you ensure compliance with airspace requirements and clarify how to safely proceed, allowing you to maintain situational awareness and ensure safety in your flight operations.
