Tyre Pressure Indication System (TPIS) is the computer that generates the error signals to Flight Warning Computers (FWC) for ECAM displays. Once the aircraft is powered up and the Wheel page is brought, all errors will be on spotlight.
during landing A320, automatically brings the Wheel page and there anything wrong will be also shown and chims go ring!, but I haven't come across any in flight pressure reduction of a wheel, but yet possible?
