GENERAL
HGS:
 HGS compatibility issue: version 20.7 (Phase 10.7) shall correct the
compatibility issue between EICAS Version 20.5 (Phase 10.5) and
HGS equipped airplane. Therefore the RA value shall be displayed
again on the HGS combiner. There will be no modifications on the
HGS system.
Ice Protection:
 "ICE COND – A/ICE INOP" message logic change: in the previous
logic, under ice condition on the ground, this message may
undesirably appear because the Anti-Ice protection is not activated.
In the current logic, on ground, if the Thrust Lever is positioned
below Thrust Set, and N2 is below 53.6%, then the message is
inhibited. Besides, it was included a time delay of 5 seconds to
activate the message.
