Operation of the HARM in SP mode is quite simple:
1- Master Arm Switch to ARM
2- A/G Master Mode ON
3- Select HARM from the TAC/Stores page
4- Press the HARM Sequence/RAID/FLIR FoV switch or [i] to cycle the ground-radar emitters on the EW page / EW HUD / Azimuth Indicator (aka RWR scope)
5- Press and HOLD the weapon release button or [LEFT ALT + SPACEBAR]
Some notes:
1. HARM range is highly dependent on launch altitude and speed. A high and fast launch at 45k MSL at 1.3M will allow engagement out to 80 nm.
2. When in SP mode, no target range is provided. Have a good understanding of where the target may be before you launch that HARM.
3. RESET will automatically select the highest threat emitter.
4. Some advanced SAM systems can shoot down a HARM. It is not a magic bullet.
