Hello fellow pilots of infinite flight!!
I just wanted to tell you that when you guys are headed East, then use Odd altitude. For example, FL 290, FL 310, FL 330, FL 350, FL 370, FL 390.
When you are headed West, then use Even altitude. For example, FL 280, FL 300, FL 320, FL 340, FL 360, FL 380.
I know most of you know this, but there are still some pilots who doesn’t know this.
Have a fun and safe flight!!
