In low-level flight, what is the correct sequence for FENCE procedures around entry and exit?

• A. FENCE-In before entry; FENCE-Out after exit
• B. FENCE-Out before entry; FENCE-In after exit
• C. FENCE-In after exit; FENCE-Out before entry
• D. No FENCE required

Answer: (A)

Managing airspace boundaries during low-level flight is what this item centers on. You perform FENCE-In before you enter the designated low-level area to confirm you’re properly authorized, have the planned route, and meet altitude and communication requirements. This upfront check ensures you don’t inadvertently enter restricted or hazardous airspace and that you’re prepared for the activity you’re about to begin.

After you’ve cleared the boundary and exited, you then perform FENCE-Out to verify you’re fully out of the area and won’t re-enter unintentionally, returning to normal flight conditions or the appropriate procedural state. Doing FENCE-Out before entry would leave you without confirming you’re entering within the allowed area, and doing FENCE-In after exit would mean you entered without the boundary check. No FENCE at all would skip these crucial boundary safeguards.
