Is this simulated in the NGX? Can't find it

Hi Vernon

 

I see from previous posts you've been familiarising yourself with our SOP’s and procedures regarding non-normals!

 

The Fire Switch Override is located beneath the respective Engine/APU Fire Switch. The Engine Fire Warning Switch is mechanically locked unless it illuminates. If you need to pull the handle without an overheat or fire condition detected (switch not illuminated) you need to push down the Fire Switch Override and simultaneously pull up the respective Fire Switch.

 

I practice Engine failure scenarios with NGX before my recurrent, the override switch is simulated but you have to be quick after pushing the override to pull the switch up. In reality as PM you’d push the button down whilst simultaneously pulling up on the respective fire switch, it’s pretty difficult to do this with the NGX because you have to this whilst also flying the plane!

 

Good Luck!

Hi sam good to see you back. That is correct i know someone who was kindly to pass on alot of materials including the latest SOPs for my eyes only.

 

Ahh i will give that a bash. Well i'm finally leaving the NGX behind and moving over to my own fully built fixed base 737NG from flightdeck solutions next year. Keep an eye out for it.

 

Take care

Very good! Make sure you keep them to yourself! Feel free to PM me if you have any queries!

I will do

Its pretty tricky to override it. Haven't managed it yet ha

Ahh you press those small round black buttons

Just to learn the meaning of the abnormal procedure , why would you override the fire switch ? Is it a "take no chances" scenario like ? (overheat detection,VIB for instance ?)

 

Could you come with an example to en-light my interest ?

 

Is there any sources out here that discuss or educate these procedures in a "helicopter" manner to explain things from top down and not vice versa ? Situation based knowledge

 

 

 

Update:

 

Found this Thread that explain a given situation about this  quite well at the end

There are a few non-normal situations where you would need to isolate the engine and/or APU from the aircrafts critical systems, as directed by the QRH. Remember the fire handle is locked UNLESS a fire or overheat detection is detected.

 

Engine Severe Damage or Separation might not necessarily cause a fire, my companies QRH instructs us to pull the affected Engine Fire Switch which if illuminated you'd simply pull the lever up. If the light isn't illuminated  you have "To manually unlock the engine fire switch, press the override and pull"

 

Another situation would be during an Evacuation where we are instructed to Override and Pull all Engine and APU fire switches by the QRH.

Thanks sam its great to have another real 737NG pilot on this site offering your help and experience.

Helpful hint: If you click and hold on the override switch then drag your mouse off it, it will remain pressed so you can click the fire handle.
