NigelOnDraft,
all correct as regards the stby instrumentation, however, GPS position, goemetric altitude and groundspeed info is all still avble on the GPS monitor page in the MCDU, although the last one may be blended with IRS info....i'm pretty sure the 320 bus has that facility- certainly the 330 and 340 bus' do. Rather useful page to have up on a dark and stormy night when it all goes black.

As I said earlier though, navigating by Lat/Long readout while flying on Sby Insts is not a skill well practiced. There if required, but you'd be bl**dy unlucky not have a radar service and/or look out of the windows
Anyone for a "No Compass No Gyro" let down "turn left now.... stop turn now"

NOD.
Yes the airbus is like any other aircraft....
Yes you can revert to basics....
Yes you are right..the DDRMI is fed from the IRSs..( I humbly apologise for this mistake).
Cheers JJ
P.s. The ISIS is the integrated standby instrument system!! And you have always got the standby compass

I kept in mind a Triple IRS Failure having a doubt about what should be do in that situation, but when does this kind of failure go to happen ? ... it's nearly impossible !
Best of all,

That was how I recovered it last in the Sim. However, are civil controllers trained to do that?

Airbus ...
Captain 87 ,
don't be so sure that Emergency Proc. on the books are impossible to occur, and that 320 is not like any others aircraft .
Because one of this days maybe you have to learn to flying it like stick and rudder a/c.
If you loose both AC bus during the take off ( image by night) until the Ram Air Turbine pressurize the Blue hyd and emergency generator come online , you are on STBY intruments only.
And i don't think is the right moment to learn some row data handling.
Cheers.

I absolutely agree with you ! ... said that, I think that everyone who hold a commercial license must be able to revert to basics anytime. Obviously night-flying is not the best moment in which we should train to do that !
An Airbus 320 is never an airplane like another, because in that situation the other aircraft we keep in mind would always crash before ... We can analize a similar to Airbus in terms of redundancy: the new Dassult Falcon 7x.

Time for ground refresher and Capt87 you surely don't agree with him. You always have PFD from batteries. After 8 seconds the RAT powers blue and you also get ND.

Vilas,
I resurrected the thread because I was looking for another topic and found that this one has and interesting one. Triple IRS failure is interesting. Very improbable scenario but not impossible. And by discussing this type of troubles we get to know and understand the aircraft systems better. Had I opened a new thread on it, I am sure someone would have posted a link to another thread that relates to the topic. So I decided to use the "search" function. I thank you for your explanation.
Max Angle,
I guess is a new record.
Did I earn a medal?
