Syracuse Hancock International (KSYR). Classic Class C example.

• 44 / 16 outer ring → ceiling 4 400 MSL, floor 1 600 MSL (add 00).
• 44 / SFC inner ring → ceiling 4 400 MSL, surface up.
• Airport field elevation ≈ 421 ft MSL, so 4 400 MSL is roughly 4 000 ft AGL — matches the standard Class C ceiling rule.
