PAL used to be available on Unicom. NLK is a bad weather factory. Carry fuel for an alternate. Tontouta would be the nearest and that's 330nm away. Work on a PNR ( practice this if you haven't had to calculate one for a while) if you cant carry fuel for Norfolk-Tontouta. Get the latest Metar prior to your PNR and divert early. Many people have become unglued by operations into NLK. The weather can change from Cavok to MDA in 30 mins. The cliffs that surround the island also generate windshear and turbulence that may also make landing a grim prospect. Any wind speed over 20 kits could create issues, depending on what aircraft you fly there in. If you can, find someone who has been there frequently and discuss your flight with them.
*Elevation is about 330'.
