KGNV Gainesville Regional — Instrument Checkride Guide

What kind of airport is KGNV and what is its IFR environment?

Gainesville Regional Airport (KGNV) serves north-central Florida at an elevation of 152 ft MSL. The airport operates inside Class D airspace with a control tower providing continuous attendance. Jacksonville Approach Control (118.175 MHz) handles IFR arrivals and departures, handing off to tower (119.55 MHz) for the final approach segment. ATIS broadcasts continuously on 127.15 MHz; ground control is on 121.7 MHz.

KGNV sees a mix of University of Florida charter operations, regional airline service, and general aviation. Traffic volume is moderate — enough to produce realistic ATC sequencing without the sustained pressure of a major hub. The airport is located approximately 10 nm southwest of restricted area R-2906, which affects routing on southbound IFR departures and is a common examiner topic.

What instrument approaches are published at KGNV?

KGNV has 5 published instrument approach procedures, sourced from AirNav and verified against SkyVector.

A VOR approach is also listed in the triads data. Always verify current minima on official FAA charts before flight — RNAV approaches may include LPV, LNAV/VNAV, or LNAV-only lines of minima depending on your equipment and database currency.

What is the runway configuration at KGNV?

KGNV has 2 runways. Runway 11/29 is the primary instrument runway with full ILS capability on the 29 end and RNAV coverage on both ends. Runway 07/25 supports RNAV approaches but carries a Part 121 restriction — it is not available for scheduled air carrier operations with more than 9 passenger seats.

Active configuration depends on wind. Runway 29 is preferred for IFR operations when winds permit. Surface conditions on Runway 07/25 are not maintained between 2330 and 0400 local — a consideration for late-night IFR arrivals.

What weather should instrument pilots expect at KGNV?

North-central Florida produces active convective weather from May through September. Afternoon sea-breeze collisions between Gulf and Atlantic moisture frequently generate thunderstorm lines that build rapidly to 45,000+ feet. These cells can make KGNV temporarily non-accessible even when the surface observation is VFR. Check convective SIGMETs and METARs from aviationweather.gov before any Florida summer departure.

October through February brings a different hazard: radiation fog. Clear, calm nights following frontal passage allow surface temperatures to drop to the dewpoint. Fog can develop after midnight and reduce visibility to below 1/4 mile before the ATIS or tower can update. Morning fog typically burns off by 0900-1000 local, but a filed alternate is essential for any early-morning IFR arrival during winter months.

Wildlife hazards are formally noted in KGNV operational data — birds and deer are documented on and in the vicinity of the airport. Pilots should be alert particularly during low-visibility approaches when wildlife is difficult to see on the runway surface.

What should you expect on an instrument checkride at KGNV?

A checkride at KGNV places you in a realistic Class D IFR environment with Jacksonville Approach providing radar service. Expect a departure clearance with an initial altitude at or below 3,000 ft MSL — Class D airspace at KGNV tops at 2,500 ft AGL, and Approach will assign a higher altitude once you are established on the departure. The DPE will verify that you read back your clearance correctly and acknowledge the departure frequency before switching.

The ILS RWY 29 is the most common DPE-assigned approach at KGNV. The DPE will evaluate whether you configure the aircraft on time, brief the approach, and maintain the localizer and glide slope within ACS tolerances — ±1 dot on each — from FAF to DA. Under ACS Task VI.B, the examiner may ask you to demonstrate partial panel on the ILS: flying the localizer without the attitude indicator.

Restricted area R-2906 lies east-northeast of KGNV. A common oral question asks how you determine whether a restricted area is active during flight planning — the correct answer involves checking NOTAMs and contacting the controlling agency (Jacksonville Center) for real-time status. Under 14 CFR 91.133, flight through a restricted area is prohibited when the area is in use unless you have ATC permission.

Missed approach execution at KGNV sends you climbing straight ahead on runway heading initially before turning. Execute immediately at DA if visual references are lost, and declare missed approach on tower frequency before switching to Approach.

Practice Questions

1. You are inbound on the ILS RWY 29 at KGNV and intercept the glide slope from below at the FAF. At DA, you see the approach lights but not the runway. Under 14 CFR 91.175(c), how low can you descend using the approach lights alone?

2. Your departure clearance from KGNV is "Cleared to Ocala via direct GNV, then V267, maintain 3,000, expect 5,000 ten minutes after departure." What does the "expect" altitude mean, and when do you climb to 5,000?

3. R-2906 is shown on your enroute chart along your planned route. What two steps must you take during preflight planning to determine if the area will be active during your flight?

4. You are flying the RNAV (GPS) RWY 29 approach with an LPV line of minima. How does LPV differ from a standard ILS in terms of guidance type and regulatory treatment under Part 91?

5. After landing at KGNV, the DPE asks about the Part 121 restriction on Runway 07/25. What does that restriction mean, and what rule governs air carrier operations?

Frequently Asked Questions

Q: What instrument approaches are published at KGNV?

KGNV has an ILS or LOC to Runway 29 and RNAV (GPS) approaches to Runways 07, 11, 25, and 29. The ILS RWY 29 is the primary precision approach. A VOR approach is also published. Always verify current minima on official FAA charts before flight.

Q: What is the airspace class at Gainesville Regional?

KGNV operates inside Class D airspace with a control tower. Jacksonville Approach Control handles IFR arrivals and departures. Under 14 CFR 91.129, two-way radio communication with the tower is required before entering Class D airspace.

Q: What are the primary runways at KGNV?

Runway 11/29 is the primary instrument runway at 7,504 × 150 feet with ILS and RNAV approaches on both ends. Runway 07/25 is 4,158 × 100 feet with RNAV approaches but no ILS. Runway 07/25 has scheduled air carrier restrictions for aircraft with more than 9 passenger seats.

Q: What tower and ATIS frequencies does KGNV use?

KGNV tower operates on 119.55 MHz. ATIS broadcasts on 127.15 MHz. Ground control is on 121.7 MHz. Jacksonville Approach handles IFR arrivals on 118.175 MHz.

Q: What weather hazards should pilots expect at KGNV?

North-central Florida produces afternoon and evening convective activity from May through September, often rapidly building to thunderstorm tops above FL350. Morning radiation fog is common October through February. Wildlife hazards — particularly birds and deer — are noted on and near the airport.

Q: Is KGNV a good checkride airport for instrument students?

Yes. KGNV offers a full ILS, multiple RNAV approaches, and manageable Class D airspace that tests communications skills without the complexity of Class B or busy Class C. Jacksonville Approach provides realistic IFR sequencing without excessive airline traffic pressure.
