3. Self-Protection (SP)
The use of the HARM in SP mode is relatively simple.
During the Advanced Course, the
EW page was briefed. So, you should have good appreciation of identifying EW targets. As such, it is not described here again.
In the game there is a free practice mission without explanatory texts to practice and deepen the steps.
To do this, open MISSION > F/A-18C > Weapon qualification - AGM-88C HARM.
If needed, activate the active pause directly after the start of the mission with
LShift + LWin + Pause. This will stop your plane in the air. So you won't get into the range of the
SAM sites too soon. Thus you can study the systems at ease, adjust them and fire the weapons. The positions should all be within the
HARM range.
Perform the following steps:
- Activate weapon main switch MASTER ARM VI-L.

- Main mode set to air/ground MASTER MODE A/G VI-L.

- On the right DDI select the EW page (Early Warning) from the TAC page to EW-PAGEVI-R
- By default the HUD is activated on the right side (PB14) (see image). If this is deactivated, the threats will no longer be displayed on the HUD (see below).

- On the left DDI you select the SMS (Stores Mmanagement Ssystem) page SMS-PAGE VI-L.

- On the SMS page you select HARM via a PB at the top PB HARM VI-L. The HARM settings page opens automatically:

- You can change the mode on the left side of the screen. RSET resets the selection of the target. This means that the most dangerous target will be selected automatically. Select STEP you switch to the next missile.
- Check out all radar emitters on the EW page or top 6 on the HUD now.
= 
The system automatically selects the biggest threat.
You can recognize the selected threat by a square border. If you want to change the selection press I.
No range indicator is displayed. So you have to know yourself if the missile can reach the target at your current altitude and speed.
Note that only the 6 most dangerous threats are displayed in the
HUD! But the missile will switch through all threats using
I.
On the EW
DDI page (or EW Independant screen) all threats are displayed. However, there is the DISPLAY switch, which when activated ensures that only the 6 most dangerous threats are displayed on the EW side (see
EW page).
- Fire the rocket with the weapon trigger button RAlt + spacebar or FIRE WEAPON HOTAS-J.
