Turn Fighting Basics: Radius, Scissors, Angles

A turn fight happens when two aircraft end up in sustained turns, each trying to get guns on the other’s tail. It is the most common way new pilots die, because a turn fight looks like a pure aiming contest and is actually an energy contest. The pilot who understands the geometry can force the other one into mistakes.

The variable that decides it: turn radius

Two aircraft in a sustained horizontal turn trace circles. The smaller circle is inside; the aircraft on the inside has the angular advantage and can eventually bring guns to bear — if it does not overshoot. Turn radius is set by your speed and your aircraft’s turning capability: slow down and your circle shrinks, speed up and it grows.

Position	Advantage	Risk
Inside (smaller radius)	Angular advantage on the enemy’s tail	Overshoot if too fast
Outside (larger radius)	Can disengage vertically at any time	Must keep the enemy from tightening inside

Overshoot: the mistake that flips the fight

Overshoot means flying past the enemy’s tail because your turn radius grew or your entry speed was too high. The moment you overshoot, roles reverse — he is now behind you. The counter-habit: if you are inside and closing too fast, ease the turn or briefly reduce speed rather than muscling through. If you are outside, you can try to force an overshoot by making him commit to a tight turn and then reversing — but only if your aircraft can pay the energy cost.

Scissors

When one aircraft overshoots and both end up crossing noses repeatedly, you are in scissors — a weaving duel where the loser is whoever ends up in front first.

• Flat scissors happen at similar altitude in a horizontal weave. The aircraft with better slow-speed handling and the discipline not to overshoot wins.
• Rolling scissors happen when the fight goes vertical: both aircraft roll and pull through the top and bottom of the maneuver. The winner is usually the one who manages energy better through the reversals, not the one with the sharper pull.

The correct entry decision

The real skill in turn fights is refusing the ones you cannot win. Before committing, run the check: is your turn radius smaller at your current speed? Can you disengage if a second enemy appears? Is there altitude under you? If any answer is no, break off — the disengage-and-return pattern in energy fighting exists exactly for this.

Drills you can run solo

1. In a test flight, establish a level turn at cruise speed and note how long you can sustain it before bleeding speed.
2. Repeat with reduced speed and compare the circle size.
3. Practice reversing the turn (roll, then pull) and feel how much energy the reversal costs.

These three numbers — your sustained turn circle at two speeds and your reversal cost — tell you which turn fights your aircraft should accept. That is the whole framework, and it is evergreen: the numbers change per vehicle, but the geometry never does. For what changes between modes, see simulator air battles.
