Aerial ignition devices are being used which can start fires by a succession of point sources or by a line of fire. Through the use of these devices, the fire manager has considerable control of the fire situation. Control of the ultimate fire behavior depends on the ignition patterns and the indrafts generated by the fires. By understanding the expected fire behavior and the fuel and environment, the manager can burn in marginal situations, thereby extending the available burning period.
