A320 emergency descent
I'm an Airline Pilot Student who is studying for A320 TR before performing it ...
I'd like to clear up a doubt about a specific procedure to be adupted when a cabin depressurization occurs with an A320 in cruise over the mountains (30.000 ft high) ... provided the CFIT procedures and GPWS operating normally. We suppose that SYS 1 + SYS 2 are INOP and the MAN control of the outflow control valve is fault due to the respective failure of the manual elect motor. So the Oxygen Masks now deployes automatically and ... (since) an emergency descent to 10.000 ft should be started immediately, is it possible to maneuvre the aircraft so close to terrain ? ... if affermative: Should the maximum 750 ft/m rate of descent (for pressurization) be matched anyway ? ...
That's just a doubt that I'm not sure could really happen ...
Thank you and Best Regards
