Minimum distance required to turn at maximum speed of an F-16

What would be the minimum distance required for an F-16 to turn either sideways or upwards in order to avoid a collision (assume an infinitely long wall both length and breadth wise).

Also would it be better for such planes to turn sideways or upwards? Which is faster and requires less distance.

• Someone please help me with the tags, I don’t think that they are sufficient. – Valay_17 Jan 24 '20 at 2:00
• To clarify, are you asking about the diameter of a 180 degree course reversal? (Because you only need to turn a few degrees to avoid a collision...) – Michael Hall Jan 24 '20 at 3:24
• @MichaelHall : I am assuming an infinitely long wall so turning a few degrees won’t help. Also, I want to know about the radius of a 90 degree course reversal, a 180 diameter would help too. – Valay_17 Jan 24 '20 at 3:27
• Ok, I read the wall part, but didn't really get it. I can't calculate the answer, but rolling inverted and pulling will give the best radius because you aren't fighting gravity. You get an extra one G from mother earth... – Michael Hall Jan 24 '20 at 3:33
• On the other hand, an upward turn (half-loop) will have gravity helping you slow down, which will decrease the turn radius assuming you're limited throughout by max permissible structural G load. You'd want to pull the power to idle too. – pericynthion Jan 24 '20 at 4:05
