We’ve all been there. You’re flying into an unfamiliar airport at night, you’re having difficulty seeing the field, and trouble identifying the runway. Airports can be hard to identify for a variety of reasons, but approaching in darkness only makes it more difficult. Perhaps the airport is located in a densely populated area and the airport lights bleed into the city lights. Maybe the airport that you’re approaching is located amid terrain that obstructs your view.
Situations like these are not uncommon for charter pilots. Just a few evenings ago I was descending IFR into Asheville, NC (KAVL) on a dark night with high overcast and scattered showers. Although the airport was VFR, the surrounding hills made me doubtful that I would be able to see the field in time to safely and comfortably descend for the visual approach that I was expecting.
Fortunately, there are some things we can do to help find our destination and set us up for the approach. Here are a few tricks that I use regularly when I find myself in this position:
- When flying into an untowered/closed tower airport: Make sure that you have the right lighting frequency. Some airports have pilot-controlled lighting that is operated on a different frequency than the CTAF. If the lights don’t seem to be working, consult your AFD. If the AFD advises that your frequency is correct, double check the NOTAMs to make sure that the lights haven’t been taken out of service.
- For towered airports: Ask the tower controller to turn up the intensity of the runway lights. This has helped me find the runway countless times. This request can be especially useful at airports that are located in a highly lit area. Controllers are happy to honor this request and will often leave the lights at the bright setting until you advise them that you are ready for them to be turned back to normal intensity.
- Load an approach: If you are an instrument rated pilot, loading an instrument approach is a great way to get oriented with a runway when you need a little help. You may need to coordinate with the tower or controlling agency if you want to fly the approach, but this has the added bonus of giving the pilot altitudes for terrain/obstacle clearance should there be any hazards present.
- Use OBS mode: If you are flying an airplane that has equipment capable of doing so, you can use the Omni Bearing Selector (OBS) button to help align you with the runway. If using this strategy, just remember: THIS IS NOT AN INSTRUMENT APPROACH. It will not provide you with obstacle clearance, nor will it line you up directly with the runway.
The pictures below should help clarify how to use the OBS to assist in airport orientation.
Step 1- Have the destination set as the next way point in your flight plan. In the picture below, The GPS is set to navigate direct to KJGG. Press the OBS button (circled in red) to engage the OBS mode.
Step 2- Once OBS is selected, use either the window on the screen (which should come up automatically when you press the button in step 1) or the OBS selec tor on your navigation head to select the inbound radial. In this example, I have selected 310 degrees, the landing runway at KJGG.
Step 3- The GPS now shows an inbound course to the airport of 310 degrees. It appears as a magenta line. The line serves as an excellent aid in airport/ runway orientation. Remember that this will not line you up perfectly with the runway, but it can still be extremely useful in planning a pattern entry or for getting your bearings.
Note: As shown below, If you press the OBS button again, the GPS will return to the navigation as previously set.
1. Ask for vectors to the airport/ runway: If you have VFR flight following or are talking to a tower equipped to provide vectors, asking for them can be a good choice. Although the controllers may not always be able to accommodate your request due to workload or equipment limitations, most will be happy to comply if they are able. Some pilots may feel silly asking for help, but my policy has always been that I’d rather feel silly for asking than look silly for being lost.
In the case of the Asheville flight mentioned in the opening of this article, my solution was to ask the controller fo r direct to the final approach fix of the assigned runway. Upon arriving there, I had no trouble seeing the VASI and was in good position to fly the visual approach. If I had wanted to be positioned a little further out, I could have asked to fly to a different fix or simply asked to be cleared for the approach in lieu of the visual. Just remember to keep your intentions clear when communicating them to the controller.
The best way to approach an airport day or night, familiar or unfamiliar, is with careful preparation. Having lighted landmarks picked out as well as being acquainted with the airport layout will pay off when it comes time to plan your pattern entry or find the airport on a dark night. Use the resources available to you to get you safely to your destination.
