I’m assuming you are referring to the Ted Stevens Anchorage airport (ANC) repaving of runways 15/33. There should be areas nearby you could fly safely in the area without compromising safety. Simulators are ok, but nothing beats hands-on experience.
To become a better drone pilot, as in any situation, practice makes perfect. Find an area nearby with no or limited obstacles and practice flying in ATTI mode at a lower altitude, maybe 50-100 feet..............and in close proximity to your position..........maybe 50 feet away. Fly around a lone tree, or an imaginary tree, trying to stay at the same altitude. Flying in ATTI mode will sharpen your skills to control the drone around objects when GPS positioning isn’t available. Flying circles, rectangles, or figure eights in ATTI mode will improve your flying abilities greatly. And all that can be done safely at lower altitudes.
Good luck, and Have Fun !
