REVISION 38
AOM-145/1114
On all EMB-145 XR models, packs are automatically reset when the
conditions for the ECS OFF signal cease to exist. When both packs
are automatically reset, pack 2 will be commanded to open
10 seconds after pack 1 opening, to avoid passenger discomfort due
to packs return.
On other airplane models, if a FADEC commands its associated pack
to close through the ECS OFF signal, the pilot must reset the pack
when the conditions for the automatic shut down of the pack cease to
exist, i.e., an automatic restart of the pack does not exist.
2 - During reverse use:
The ECS OFF signal is not activated during reverse use.
