Flying the pattern at KMDQ

Madison County Executive Airport-Tom Sharp Jr Field is non towered, so the pattern is self announced on CTAF 123.0. AC 90-66B asks for a report on entry and on each leg, and for the standard 45° entry to downwind at pattern altitude.

All ends are left traffic, which is the FAR 91.126 default — turns to the left unless the field charts otherwise. The full entry procedure is here →
