In Class II airspace and not in RADAR contact, keeping a NAV Log is:

• A. Optional
• B. Mandatory
• C. Prohibited
• D. Encouraged

Answer: (B)

In Class II airspace and not in radar contact, keeping a NAV Log is mandatory. When you’re not being surveillance-monitored by ATC, you must maintain your own continuous position and progress record. The NAV Log captures leg-by-leg data—planned and actual times, distances, headings, winds, fuel on board, and remaining fuel—so you always know where you are, where you’re going next, and how much fuel you have available. This self-tracked information supports accurate ETAs, helps you detect deviations promptly, and ensures you can safely manage the flight and coordinate with ATC if needed. Since this is a required practice in non-radar airspace, it isn’t optional or merely encouraged.
