What is required for aircraft to operate on an ALTRV?

To operate on an ALTRV (Alternative Trajectory Request), aircraft require approval through military channels. This is primarily due to the nature of ALTRVs, which are typically utilized for military operations and specific airspace management purposes. The process ensures that the operating decision aligns with national security and airspace safety considerations.

Military operations may involve unique flight paths or requirements that necessitate coordination with relevant military authorities. This helps to maintain effective communication and situational awareness among various airspace users, ensuring that operational proceedings do not interfere with one another.

The other options do not meet the criteria for ALTRV operations. For instance, flight planning through civilian airlines is not relevant to the military operations that these requests often pertain to. Similarly, registration with the FAA does not inherently grant the necessary approvals for the unique situations that ALTRVs address. Lastly, the idea that no approval is needed contradicts the established protocols for military and national airspace integration.
