What is the recommended launch angle for signal flares?

• A. 30 degrees
• B. 45 degrees or more
• C. 60 degrees
• D. 15 degrees

Answer: (B)

For signaling flares, you want the flare to rise high and stay visible as long as possible. Launching at 45 degrees or more gives a strong vertical component, so the flare climbs higher, reaches a good altitude, and burns longer in the sky. That combination makes it easier to spot over distance and above obstacles. Flatter angles produce lower, shorter flights where the flare is visible for a shorter time, making detection harder. Very steep angles can keep the flare high but reduce how far it travels horizontally, which isn’t as reliable for signaling over a wide area. So, 45 degrees or more strikes the right balance for reliable visibility.
