During the departure from LAS; climbing through 12;000 FT via the STAAV 5 RNAV; while crossing the STAAV waypoint; ATC asked if we were going to make the altitude restriction at TRALR since it looked like we had missed the altitude restriction at STAAV. We replied that we did not show an altitude restriction at TRALR. ATC replied that there was a 17;000 FT restriction at TRALR and to contact the next Controller on XXX.XX frequency. We checked in with the next Controller and inquired an altitude restriction at TRALR to which the Controller replied that he did not show a restriction at TRALR and standby. ATC again contacted us within a minute and verified there is no altitude restriction at TRALR. At or above crossing restrictions on departures are not often difficult to comply with.A number of factors contributed to this event:- Low climb rate due to the high gross weight of this flight- Accelerating out of 10;000 FT- New procedure out of 10;000 FT AFL not AGL;- The location of this crossing restriction of 13;000 FT- Typically ATC gives a new altitude deleting the restriction- Insufficient monitoring of the automation[The deviation could have been avoided by] improved monitoring of the:- At or above climb restrictions;- Color changes (warnings) on the MCDU and PFD.
An A320 flight crew; crossing STAAV at 12;000 MSL on the STAAV RNAV SID from LAS was reminded by ATC that the fix was required to have been crossed at 13;000 and asking if they intended to cross the next fix; TRALR; at 17;000. TRALR has no crossing restriction published on the chart.
