Hey, Whenever I press the Direct To Button on the 90B, I can't enter the airport ICAO identifier. The whole ICAO field just keeps on blinking and no matter how I turn the Inner and Outer left knobs , It just doesn't work...so I am unable to set a direct to destination. Thanks.
Most lights reflect on the ground as well. Strobes, Navs, beacons.. etc. reflect onto the ground in most planes. That is one major component. I know this may be a far fetched idea but how about simulating the decreasing intensity of the lights with age.
