Grosse Ile Muni sits in Detroit/Grosse Ile, Michigan. Field elevation is 590.5 ft MSL. The airport has two runways. The longest is 4,846 ft on 04/22. There is no control tower. No ILS approaches are published. Pattern altitude is not published. Use standard 1,000 ft AGL for light piston traffic unless ATC or the current Chart Supplement says otherwise.
The on-field FBO is Grosse Ile Municipal Airport. It carries 100LL and Jet A. Call the field directly at (734) 675-0155 for current service details. Detroit Approach handles clearance delivery. The published remarks also flag birds and deer on and near the airport. Ultralight and powered parachute activity also occurs nearby. That matters here.
Runway 17/35 is 4,424 ft concrete. The Chart Supplement notes extensive peeling and cracking on that surface. Treat it as a possible FOD issue. Runway 22 has a displaced threshold with a steep approach slope to that threshold. Runway end identifier lights are active on 04 and 22. PAPI is available on both runways. Medium intensity runway lights are pilot-controlled on CTAF. This is a field where a careful preflight and a clean scan on rollout pay off.
