Sidewinder

1. Missile Master - READY
2. Gun Missile Switch - MISSILES
3. Check Missile Status Light is Green (if not use Station Bypass to step until a working missile can be found, trigger can also be used to step but runs the risk of inadvertantly firing a sidewinder). Tone should be heard.
4. Listen for higher pitched tone indicating a valid heat source and depress second stage trigger to fire the missile.
