What KONZ publishes

Instrument approaches at KONZ

Grosse Ile Municipal has 3 published instrument approaches of 2 types (RNAV (GPS) and VOR). 2 of them offer vertical guidance; RNAV (GPS) gives the lowest minimums. One is circling only — bringing you to the airport rather than a runway, to circle for whichever runway the wind favors at circling minimums.

No published approach to runway 17 and 35: landing on those ends in instrument conditions means a circling approach or a visual after breaking out.

Departures and arrivals

Grosse Ile Municipal publishes 12 departure procedures (SIDs) — charted routes from the runway to the en route structure, assigned by ATC in the clearance. It also publishes 4 arrivals (STARs), the mirror image: charted routes from the en route structure down to where the approach begins. Each one is in the list at the foot of this page with its continuation pages.

Takeoff, alternate and surface information

  • Takeoff minimums are published for KONZ. Standard is 1 statute mile visibility for one and two engine aircraft (½ mile for more than two) unless this section says otherwise; Part 91 operators are not bound by them but the obstacle notes apply to everyone.
  • Non standard alternate minimums are published: if you file KONZ as an IFR alternate, the required forecast is higher than the default 600-2 for precision or 800-2 for non precision approaches. Check the alternate rule tool.
