Fenix A320 engine bleed

Recommended Posts

Hi I sent in a ticket to fenix about 5 days ago but haven’t heard anything back, figured I’d ask here.  I haven’t been able to start the engines from either cold and dark or APU on state. When changing from engines running to cold and dark or APU running the aircraft will shut down but as soon as the ecam is on N1 indicated 4.1% and EGT is about 280.  No fault light for with packs is on. After starting APU and opening APU bleed when engine ignition and fuel are turned on nothing happens. When bringing up the bleed page on the ecam it appears the engine bleeds never open.  I have tried everything I can think of to get them to open but they won’t. I’ve tried uninstalling and reinstalling, have never been able to get the engine bleeds to open and have never been able to get N1 below 4.1%. Anyone else have a similar issue? What am I missing?  
 

thanks for the help

Galen

Do the engines run if you select Ready state on the EFB?

Yes the engines run no problem when I select the ready state. I’ve even tried shutting them down to try and restart and the N1 only dropped to 4.1, was unable to restart after that.

You really don’t need to mess with any of the packs etc. Apu on, Apu bleed on, ign start introduce fuel. Make sure fuel pump for Apu is on before starting the apu and make sure the fuel pumps for the Engines are on before starting. Sorry out n about can’t type in more detail, plenty of YouTube videos 🤙🏼

APU doesn't need any fuel pumps on to start.

That’s essentially what I’ve tried multiple times. I have a feeling the engine bleeds won’t open because n1 is 4.1 and not 0.  Haven’t had any issues starting the APU or opening the APU bleed.

No not needed but I read somewhere it’s good for longevity of the APU. Mates a 320 pilot I’ll ask him why and how tomorrow morning.

The APU in the A320 has its own dedicated fuel pump that comes on automatically when the APU master switch is energized. It is independent of the main engine fuel pumps.

Wrong.

On the A320, the APU fuel pump starts automaticly when you push "ON" on the APU master switch (unless any fuel tank pump is online)

I read on their Discord page last week, that pumps were not needed to start APU, and I have always started APU with all pumps off.

I know you said wrong, but he's really not. You don't need to turn on any fuel pump to either start engines or the APU. The engines are gravity fed fuel - the pumps are there for flight because there's no guarantee down is where fuel will go.

Source: EasyJetSimPilot did a thorough explanation during Fenix' live stream period. Unlike him, I'm not typed, so I'll only offer his explanation as a source here.

Take-offs are optional, landings are mandatory.
The only time you have too much fuel is when you're on fire.
To make a small fortune in aviation you must start with a large fortune.

There's nothing less important than the runway behind you and the altitude above you.
It's better to be on the ground wishing you were in the air, than in the air wishing you were on the ground.

You’re  both right, he’s getting into the weeds and explaining that the Airbus logic automatically turns on the fuel pump for the APU.

 

As far at the pilot is concerned they do not need to do anything with the fuel pumps to start the APU.

Normally, you don't even "need" to turn fuel pumps ON before you start the engines, the gravity does the job for you (assuming you are not in the air!).

 

Oops, WestAir was faster than I ! 😉

No, because if electric driven pumps are OFF the APU fuel pump starts by itself.

It's a difference between not needing a fuel pump vs not required to push an additional fuel pump button 😉
