Weapon/Fuel tank Jettison

[LtMacGowan]

How do I jettison fuel tanks or un used weapons in the F/A-18? the F-15 had a command to do so but unless im missing it in the control panel im not seeing it. thanks

Note that master arm must be on to use selective jettison.

kinda confusing on the selective jett

This isn't working for me. I try to jettison the center tank in the Raven One campaign, but with Master Arm on, Center selected, and Stores on the Jettison button, nothing happens. Only Emergency Jettison works. But wouldn't this be bad if I have missiles that I don't want to jettison?

Put the SEL JETT rotary switch to Rack/Launcher. Stores is used for ejecting a store off of another launcher that is attached to the weapons pylon.

Steps should be:
1) Master Arm on
2) Select station on station select panel (Green triangles)
3) Rotate to Rack/Launcher (because you’re releasing the hooks on the BRU-32 to drop the tank)
4) press the SEL JETT red button

Off they go.

Speaking of racks, in what cases should I dump racks along with weapons? Say, if in multiplayer the base has a finite amount of munitions, are racks also finite? I mean, it does make sense to dump racks as well in order to get rid of their weight and drag, especially if there's a functionally infinite supply of them, but I don't think it's that simple IRL.

So an example would be the BRU-33/55 for dual carriage of bombs. If you select rack/launcher, and hit the button, the rack and associated bombs are going off from where they attach to the pylon, the hooks on the BRU-32. Where if you select stores and hit the button, the fire signal goes to jettison the bombs off of the BRU-33/55.

Real life situation would be bomb is a dud and doesn’t come off with the pickle. Rather than jettison the whole -33/55, which is finite in the real world, they would jettison the store first to save the rack and troubleshoot after recovery. If a full emergency, then and only then would they jettison the rack using the rack launcher option.

I’ve spent 14 years working on Hornets and as an avionics guy, have done countless weapons release and control checks. I haven’t looked at a checklist in a while, but I think remember only selecting stores for the CVER (-33/55) checks, all other SEL JETT checks were in Rack Launcher.

Without any reading, I couldn't jettison the other day until I went into A-G mode.

A-A (which I was in) = a no no.

A-G = pop pop & stores gone.

Lol oops. Yeah forgot about that, thanks. Second step then should be A-G, then the tree and rotate switch then press. Like I said, been a while…a long while.

Never had problems with selective jettision.
1. Select stations (green triangles) - in case of ceterline tank, select ceterline station

2. Rotate knob to Stores

3. Master Arm on
4. Press Selective Jettision
5. Verife Stores page
6. Master Arm off
7. Knob to SAFE

8. Deselec centerline station.

Yeah, that's the thing. I tried exactly this and nothing happened. I'll try the other methods (a/g mode, rack selected instead) and test later when I'm able.

Remeber that many buttons need ~1 sec press, not just quick mouse click.

IRL, Rack Jettison is intended for an emergency. If you have a hung store (bomb or missile that did not release when commanded to) the first step is to attempt to jettison the store. If that fails, then the next step is to jettison the rack. If a mechanical failure with the rack caused the hung store there's a chance that it'll also fail to jettison. In that case, punching off the entire malfunctioning rack is the solution. Navy planes tend to have more redundancy for this sort of thing as landing on the boat with a hung store is an absolute no-go.

In general the preference is not to jettison the rack, stores jettison is attempted first, and the rack punched off only if it won't release the store. It shouldn't make a difference with a fuel tank, as those have no rack.
