I'm looking for the indication of the outside static air pressure in the cockpit. Where is it located? One of the ECAM pages?
Thanks!

2$\begingroup$ What is your reason to believe it should be displayed as anything else than pressure altitude? $\endgroup$– Jan HudecCommented Nov 23, 2019 at 10:34

1$\begingroup$ My incompetence in avionic... Is the static pressure used somewhere else as in pressure altitude? For some other calculations that are not displayed? $\endgroup$– ptiza_v_nebeCommented Nov 23, 2019 at 12:52

$\begingroup$ Airspeed measurement requires static pressure (dynamic pressure is total pressure, in pitot probe, minus static pressure), but the usual approach is to measure the difference directly (though I don't know whether A320 ADIRU does that). And then there are some altitude-dependent limits in the flight laws. Also the transponder transmits pressure, ignoring the baro setting. $\endgroup$– Jan HudecCommented Nov 23, 2019 at 22:32

$\begingroup$ Maybe one of the computers with displays shows for maintenance purposes raw static pressure value? So the technician can check pressure against some value in the ground test equipment? $\endgroup$– ptiza_v_nebeCommented Nov 24, 2019 at 12:41

1$\begingroup$ I doubt practical test equipment would show anything else than pressure altitude to be directly compared with the altimeter. That way it can be used with any altimeter and the point of the test is to check the altimeter reading anyway. $\endgroup$– Jan HudecCommented Nov 25, 2019 at 6:47
