Cross Bleed usage with single engine during taxi - A320

[Jay320]

A question regarding Single engine procedures- In one engine taxi procedure, why is it that in CEOs we need to put the cross bleed to open, while we don't do the same for NEOs? Appreciate give with airbus reference. Thank you guys

It’s not a requirement for the CEO. In fact if you do, you get a slight increase in idle thrust and higher fuel burn from the single engine which almost defeats the point of a single engine taxi. However, both packs will operate.

On the NEO, it’s not recommended as you get a significant increase in thrust on the running engine which can make controlling the speed when taxiing an issue.

It would be more polite if you sent yours first, instead of making a wrong claim in a definitive plural of the opening post. You know ...
