Jettisoning payload IRL

[Black_Hawk]

What's the procedure with military jets? With outer pylons as well as with internal stores.

I mean when landing.

Do they drop it somewhere (if so where and who picks up the weapons then)?

Same question with carrier-based aircraft.

USA and Russia. (And other countries aswell).

 

I just had a chat with a friend and we brought up that topic. Any info would be great :smilewink:

They would drop stuff over un-populated areas most likely, if they are either above landing weight or they need to clean up the aircraft for other reasons (ie. ran out of fuel)

 

If you are overweight, you might consider dumping fuel instead of stores as dumping fuel might in fact be cheaper.

And if the landing goes bad, you won't burn as long.

Since you'll have plenty of fume in the tanks, you just explode? :D

Don't know about jettisoning fuel and stores, but with the Su-27 (mig-29 perhaps too, forgot about that one), when attempting a dead stick landing, or when the brake systems have failed, the procedure is to jettison the canopy when on approach. It's never explained in the manuals WHY it needt to be done, but I suspect it has something to do with the 75 km/h 'zero'-zero ejection procedures. So, if the shit hits the fan during the roll, the pilot still can egress safely, and not get ejected into a big piece of plexiglass with sharp corners.

nah you just create ab big hole in the Runway cuz you didn't jettison your 12 Mk82s ::megalol:

In the NATO vs. Yugoslavia campaign the NATO jets had designated "dump areas" in the Adriatic Sea where they could drop ordonance into the adria.

Yup, this was the case - I work on commercial ships and was in the med at the time and every day there were warnings (notices to mariners / NAVTEX) of unexploded ordinance being dropped in the Adriatic.

The drop zones at the time seemed to me to be widespread and fairly random.

At least for the 29, the procedure is to jettison the canopy if there might be a need to eject from the aircraft at speeds below 75km/h. Things like engine fire during taxi/take off roll etc..

Areas were called "EJAs": Emergency Jettison Areas

 

Usually, every wing has a certain jettison area in the vicinity of the base, and even bail-out areas are defined.

 

When you are airborne with weapons, and you have a problem where a safe landing can not be assured, it is better to drop the load before attempting to land. Getting rid off any ordnance is not only important because of the aircrew, but also important to the safety of the firemen who might have to enter the aircraft in a rescue attempt. The ammo of the guns remains a problem all the time, because there is no way of dropping the ammo at all.

 

Often - even without any weapons mounted - at least fuel dumping has to be considered to bring the aircraft to the max weight limit allowed for a safe landing. Fuel dumping will then be done over unpopulated areas or over sea in some thousands of feet altitude, so the fuel plume will have a chance to evaporate before it comes down to the ground and spoils it.

 

Another problem is hung ordnance, that are misfired weapons where either the ignition did not occur (missiles) or they stay at the wing station after one tried to drop them. In this case, one can't be sure when or if the weapon will leave the wing station, so this is a very nasty problem. For a misfired missile, jettison should work. If jettison does not work properly, you have a real problem....
