Which routes are not subject to the ZAE and ZHU LOA provisions?

• A. V9 or J35 or between fix pairs SQS/MCB, MHZ/MCB or ROMAR/MCB are subject to LOA
• B. Other routes cleared, regardless of radar appearance, are not subject to LOA
• C. All routes are subject to LOA
• D. Only routes ending at MCB are subject to LOA

Answer: (B)

The key idea here is that LOA provisions are applied only to a specific set of routes. In the ZAE and ZHU LOA framework, certain routes are designated to be subject to the LOA (for example, V9, J35, and particular fix-to-fix segments). Routes that don’t fall into that designated set are not governed by the LOA, regardless of how they appear on radar. Therefore, the statement that other routes cleared, regardless of radar appearance, are not subject to LOA correctly captures the rule: LOA applies only to the listed routes, while all other routes are outside its provisions. The other choices imply LOA applies more broadly (to all routes or only to routes ending at a specific fix), which is not the case.
