How to read

The top lane is always the active baseline (BASE + FM). Secondary lanes stack temporary and probabilistic deviations in the order they appear in the TAF.

Grinnell Rgnl is in Grinnell, Iowa. The field elevation is 1,008.4 ft MSL. It has one runway, 13/31, which is 5,200 ft long and paved concrete. There is no control tower. Pattern altitude is not published, so use the standard 1,000 ft AGL for light piston traffic unless the current Chart Supplement says otherwise.

No ILS approaches are published here. The published remarks also say airspace determination is pending, so check the current Chart Supplement and your sectional or TAC before you go. Runway 31 is listed as the calm wind runway. Both runway ends have displaced-threshold approach slopes noted in the remarks, so brief that before arrival. The runway lights are medium intensity. They start on low intensity. Use CTAF 122.8 to bring up the lighting and to activate the PAPI and REIL on runways 13 and 31.

Lowry Flying Service is on the field. They carry 100LL and Jet A. For after-hours fuel, call the number in the Chart Supplement or the FBO directly. This is a non-towered field with one runway, so expect self-announce traffic and stay sharp on CTAF.

Frequently asked questions

What is the runway length at KGGI and can a piston single use it?

KGGI has one runway, 13/31. It is 5,200 ft long. That is plenty of runway for most piston singles, but always account for weight, density altitude, wind and runway condition.

Is Grinnell Rgnl towered or non-towered?

KGGI is non-towered. Use CTAF 122.8 for self-announce traffic and runway lighting activation.

What is the pattern altitude at KGGI?

Pattern altitude is not published in the facts. Use the standard 1,000 ft AGL for light piston traffic unless the current Chart Supplement says otherwise.

Does KGGI have an ILS approach?

No ILS approaches are published for KGGI. Check the current Chart Supplement for the latest instrument procedure set before you file or launch.

Which runway is the calm wind runway at KGGI?

Runway 31 is listed as the calm wind runway. The runway headings are 131° and 311° magnetic.

Which FBO is on the field at KGGI and what fuel do they carry?

Lowry Flying Service is the on-field FBO. They carry 100LL and Jet A.

How do you turn on the runway lights at KGGI?

The runway 13/31 lights are preset to low intensity. Use CTAF 122.8 to increase intensity and to activate the PAPI and REIL on runways 13 and 31.

Are there any runway approach slope or obstruction notes at KGGI?

Yes. The published remarks note a 25:1 approach slope to the displaced threshold on runway 31 and a 35:1 approach slope to the displaced threshold on runway 13. Review that before arrival.
