The F/A-18 Hornet is a high-fidelity combat flight simulation plane, meaning that jettisoning its fuel tanks is not as simple as pressing a single button. To drop the fuel tanks, you must first select the station you want to drop (CTR, LI, LO, RI, or RO). Then, use the Select Jett knob to choose what you want to drop from that station. Next, turn the Master Arm ON and push the red Jett button to drop your selected items. Finally, dial Select Jett back to Safe and secure the Master Arm. If you need to act quickly, you can use the Emergency Jettison button, which will drop all tanks and air-to-ground munitions but not your missiles.

Emergency fuel tank jettisoning
In an emergency, you may need to jettison your fuel tanks quickly. Here is a step-by-step guide to emergency fuel tank jettisoning in the F/A-18 Hornet:
First, locate the two panels to the left of your fuel gauges. On the upper panel, select the station or stations (CTR, LI, LO, RI, or RO) from which you want to drop fuel tanks. If you need to jettison fuel tanks from stations 4 and/or 6, you can skip this step and proceed to the next one.
Next, on the lower panel, you will see a red button labelled "Left Fuse" and "Right Fuse". Push this button to initiate the emergency fuel jettison. This will drop all fuel tanks and air-to-ground munitions from the selected stations. Note that this will not drop your missiles.
If you have time and want to be more selective about what you jettison, you can follow these steps:
- After selecting the station or stations, use the "Select Jett" knob to choose exactly what you want to drop from those stations (Rack, Lchr, or Stores).
- Turn the Master Arm ON.
- Push the red "Jett" button to drop the selected items.
- Dial "Select Jett" back to "Safe" and secure the Master Arm.
Remember that emergency fuel tank jettisoning should only be used when necessary, as it will result in the loss of all fuel and munitions from the selected stations.

Selecting the station to drop
To select the station to drop, you must first determine which station(s) you want to jettison. The F/A-18 Hornet carries fuel on either CTR, LI, and/or RI. Once you have identified the station(s) you want to drop, you can proceed to the next step in the selective jettison procedure.
It is important to note that if you want to jettison stations 4 and/or 6, you do not need to select the stations first. Instead, you can dial "Lfus" or "Rfus" on the "Select Jett" knob and follow the subsequent steps.
To select the desired station(s) for jettison, you can refer to the following instructions:
- Locate the two panels to the left of your fuel gauges.
- On the upper panel, select the station(s) you want to drop by choosing from the options: CTR, LI, LO, RI, or RO. For the F/A-18 Hornet, you will typically be selecting CTR, LI, or RI as these are the stations that carry fuel.
- After selecting the station(s), you will use the ""Select Jett" knob to specify what exactly you want to drop on those stations. You can choose between "Rack/Lchr" or "Stores".
Once you have completed this step, you can proceed to turn on the Master Arm and push the red "Jett" button to initiate the jettison of the selected station(s). Remember to always refer to the official documentation or guides for the most accurate and up-to-date instructions.

Using the Select Jett knob
To jettison the fuel tanks from an F/A-18 Hornet, you must first select the station you want to drop. The Hornet carries fuel on either CTR, LI, and/or RI. You can do this by dialling "Lfus" / "Rfus" on the "Select Jett" knob.
Next, you must use the "Select Jett" knob to choose what you want to drop from the selected station. You can choose between Rack/Lchr or Stores. If you select Stores, only the fuel will be jettisoned, while selecting Rack LCHR will also dump the rack that is used to mount the fuel tanks to the pylon.
After selecting what you want to drop, you must turn the Master Arm to ON. Then, push the red "Jett" button to drop the selected item. Finally, dial "Select Jett" back to "Safe" and secure the Master Arm.
It is important to note that the rotation hotspot and button push are very close, so be careful not to accidentally jettison something you didn't intend to.

Activating the Master Arm
To activate the Master Arm to jettison fuel tanks in an F/A-18 in DCS, you must first go through a selective jettison procedure. This is because the Hornet is not a low-fi plane, and therefore does not have a single button to jettison fuel tanks.
First, you must select the station you want to drop. The Hornet only carries fuel on either CTR, LI, and/or RI. Next, use the "Select Jett" knob to select what you want to drop on that selected station. This could be Rack, Lchr, or Stores.
After you have selected what you want to drop, you can then activate the Master Arm. Once the Master Arm is on, you can push the red "Jett" button to drop whatever you selected.
Finally, dial "Select Jett" back to "Safe" and secure the Master Arm. If you want to jettison stations 4 and/or 6, you don't need to select stations first. Instead, dial "Lfus" or "Rfus" on the "Select Jett" knob and then follow the rest of the procedure as normal.

Pushing the Jett button
Firstly, you must select the station you want to drop from the following options: CTR, LI, LO, RI, or RO. The C Hornet only carries fuel on either CTR, LI and/or RI.
Secondly, use the "Select Jett" knob to select what you want to drop on that selected station, either Rack, Lchr, or Stores.
Thirdly, turn the Master Arm ON.
Finally, you can push the red "Jett" button to drop the selected items.
After pushing the "Jett" button, you should dial "Select Jett" back to "Safe" and secure the Master Arm. If you want to jettison stations 4 and/or 6, you don't need to select stations first. Instead, dial "Lfus" or "Rfus" on the "Select Jett" knob and then follow the remaining steps as outlined above.
An alternative method is to use the emergency jettison procedure. This will drop all of your A/G weapons and fuel tanks, but it will not drop your missiles. To do this, simply push the red "Emergency Jett" button.
