A320 BLEED 1+2 fault FL200？
I worked on this for a quiet long time。can anybody explain why in the QRH BLEED 1+2 fault，the procedure asks for a descending to FL200 instead of FL225？In the latest version QRH and FCOM the altitude are all the same FL200.
For our fleet, a320 all equipped with Honeywell 131-9A,which supply a ceiling of FL225 for one pack. So why FL200 in procedure ？ Many thanks！
