Chart Wise: Rangeley Lake Seaplane Base (M57) RNAV (GPS)-C

A new Instrument Flight Rules (IFR) procedure has been established for the Rangeley Lake Seaplane Base, designated as M57. This procedure utilizes a Global Positioning System (GPS) navigation aid, specifically an RNAV route, to guide aircraft through the airspace. The core element of this IFR approach involves a mandatory turn at the Final Approach Fix (FAF). Furthermore, pilots are required to maintain awareness of their own altimeter readings during the descent phase. These specific requirements reflect operational considerations related to landings within the unique terrain and weather conditions surrounding Maine’s Rangeley Lake.
