Hi there,

We recently implemented the ability to perform a crossbleed engine start in the Development Version of the A32NX. This procedure allows the second engine of the aircraft to be started from pressurized bleed air of the first engine, rather than the APU.

It's a procedure that is not commonly used in real life; however, it is an excellent trick to have up your sleeve if your APU is INOP! The relevant indications on the ECAM are provided by realistically simulated pressure and temperature sensors. A fully-fledged, physical fluid simulation computes the airflow through pneumatic ducts and dynamic valves between different components. This means that accurate readings can be expected throughout the full operating envelope, including abnormal situations. Refer to our documentation to learn about the crossbleed start procedure.

Refer to our documentation to learn about the crossbleed start procedure: https://docs.flybywiresim.com/pilots-corner/advanced-guides/engines/crossbleed-start/

 

And some while ago we also implemented different automatic Call Out variations, which are now selectable in the flyPad. The basic configuration offered by Airbus is set as the default. You can customise to suit your desire, subject to a couple of rules:

• one of "four hundred" or "five hundred" is mandatory,
• only one of the 2500 feet options can be selected.

There's a button at the bottom to reset back to the basic configuration at any time. To access the options press the settings icon at the bottom left of the flyPad, choose "Aircraft Options/Pin Programs", and then press "Select" next to "Automatic Call Outs".

 

Happy flying.

It's used a lot more than you might think. I worked for a major US Airline and our safety regulations only allowed us to air start one engine at the gate. The pilots would have to crossbleed start the second engine after pushback. Very cool that you modeled this.

Yeah I saw it all the time when I worked in DLH... the CRJ's did it often.

Hi there

You guys are the gift that keeps on giving. Thank you for your efforts on this incredible freeware plane. I fly it often and it's incredible. Don't forget! They have a donation section available for all those that can give. https://opencollective.com/flybywire

Thanks FBW for your continued development of this aircraft.

Easyjet is using single engine taxi almost always, both for departure where they start engine #1 halfway through taxi as well as for arrival where they almost instantly turn it off when it has cooled down and coast to the gate with only a single engine. I am not sure if they keep the APU on for that though or if they use crossbleed to start it, that is the question.

Will we ever have callouts for v speeds/rotation?

Where is the intermediate callouts ?

The A320 does not have any such callouts. Some of the larger Airbus aicraft have a V1 automatic callout, but not the A320.

These are implemented in the new flight warning computer which is still in development. The automatic call out work here is partially to prepare for the new FWC.
