Where is the Agent Discharger for APU?

[BiBa]

Left & Right Engines T-Handle Fire Extinguishers have their appropriate Agent Discharge in the Key Command.

 

But shouldn't also the APU T-Handle Fire Extinguisher have one! Where is its Agent Discharge in Option/Controls? (see attachment)

That is not what that switch does.

 

From the manual.

Figure 93. Fire Extinguisher Discharge

Once one of the three “T” handles has been pulled, you may press the FIRE EXTING DISCH switch on the right side of the dash left or right. Pressing left or right activates the left or right pressurized extinguisher bottles to the designated area. As such, you have only two bottles of extinguisher to use.

That is not what that switch does... From the manual.

... As being defined as Left & Right Agent Discharge in the Key Command, I assumed that only the Left Discharger is to be operated with Left Engine fire and so on, so I resumed with the false assumption, the APU must also have one of its own. A small linguistic misunderstanding, because as having two independent Dischargers, it would have been better citing them as no One and Two instead of left and right... So with only two Dischargers it's left to hope not having to deal with three fires at the same time!:pilotfly:

 

Thanks for clearing me up

Wrong still, left and right has nothing to do with what engine it goes to. The A-10 has two fire bottles. Left and Right is the correct designation and not confusing at all if you understand the system.

 

If you move the discharge swicth to the left it fires the left bottle,. Move the switch to the right and it fires the left bottle. As to which engine or APU that the agent goes to simply depends on what T handle you have pulled.

... I have already admitted, that I had a false assumption - I was just trying to explain how this left - right Discharger thing could be misperceived, as recently in an online chat other Simmers had it also in the wrong way like I did...

 

The thing is: if the Left Discharger can go to the Right Engine or to the center APU, it's not crucial if the Dischargers were placed one above the other -Up & Down or behind each other- but the only decisive thing to know in case of two intermediate emergencies is, that the first Discharger bottle has been consumed and the second is still operable.

 

Making a comparison with the Ka-50 Fire Extinguisher systems, once a discharger is pressed, there is a button light going on, whereas in the A-10C in a stress situation, there is no optical visualisation to remind you which Discharger you've already used... In that case the Ka-50 system is obviously the Winner!

if you move the switch one stop (to left or right). you have still some hope...

if you move it over two positions (from left to center to right) you know to pray or to eject soon....
