Cruising altitudes aren’t chosen arbitrarily; they depend on wind, speed, and weight, among other factors. They are also determined by direction. If you didn’t know this already, there’s a set of rules for IFR cruising altitudes:
Use them! PLEASE use them!
It’s pretty simple to understand, really. If you’re going east, fly at odd altitudes (like FL310, FL350, FL390), and if you’re going west, fly at even altitudes (like FL280, FL320, FL360).
There’s been numerous topics about this, but people still seem to not understand, even on the expert server! I’ve had multiple near-collisions in the past month. And it’s not because I’m flying super high traffic routes either.
I understand sometimes you’re feeling lazy or are thinking, “what are the odds I run into someone while I’m cruising?” (I’ve been there), but it doesn’t take that much effort to increase or decrease your cruising altitude by 1000 feet. Please clean up yall act, especially on the expert server…
