What is Time of Flight (TOF) and what factors influence it?

Time of flight is the time a round spends in the air from firing until it hits the target. How long that lasts depends on how far away the target is, how fast the round leaves the muzzle, and the resistance of the air it moves through. If the target is farther, the projectile must travel longer, so it stays aloft longer. A higher muzzle velocity lets the round cover the distance more quickly, reducing TOF. Air resistance slows the projectile and can extend the flight time, especially over longer ranges or at higher speeds. Gravity also plays a role by pulling the round downward, which interacts with the launch angle to shape the flight path; in simple, drag-free terms, TOF grows with the vertical component of the initial velocity and decreases as that velocity is larger or as gravity has less time to act, but drag and elevation change the real-world behavior. So the best description is the time a round takes to reach the target, influenced by how far away the target is, the muzzle velocity, and air resistance. The other interpretations involve timing before firing, the distance alone, or the interval between shots, none of which capture the actual flight time of the projectile.
