I’ve noticed that on nearly every airliner flight I do, I encounter, at least, one aircraft at my flight level flying directly towards me. Often these aircraft are within frighteningly close range.
I use Real-Time Online air traffic.
It is my understanding that flight levels are divided by odd/even for 0°-179°/180°/359° courses.
Does the sim (ATC) not recognize this? I’m confused as to why this continually happens.
Does anyone else note this behavior?
