LOL....you really made me laugh loudly about the ejects seats.
yes ADIRs is IRS integrated with ADR.
the thing is .... if the residual GS is 5kts or more...we do a quick re-alignment, but usually the GS after landing when parked at the gate is zero...so the need fo re-alignment is not required provided we have GPS priamry.
but the pax route map not showing or showing with some mistakes is confusing.
thanks for you input.
