Four months into a six month deployment, you are a solo pilot returning to home base after an uneventful overwatch mission to a non-disclosed desert location. Your mission was extended 90 minutes requiring at least one additional aerial refuel. The moon has now set. A shift in prevailing winds causes an infrequently used runway to be active. You are less familiar with the approach to this runway and have only used it during VFR conditions. The instrument approach plate reveals you will fly a prolonged DME arc taking you out over the unlit desert away from the dimly lit base. While flying the above instrument approach, you take another look at the approach plate. When you look up again the airfield lights are visible through the upper portion of your canopy. You did not sense any change in your aircraft attitude. Which of the following best describes what happened while you looked at the approach plate? OA. The black hole effect has amplified the normal reflection of the airfield lights…
