Narrative:

From jax to mia on oct/sat/95 we were given a heading to intercept the heatty arrival southeast of vrb (which consists of the 162 radial off vrb). On our EFIS display the 162 radial was set up on the captain's side and the inbound radial (the 198 radial to vkz) was set up on my side. Both displays showed both radials superimposed on them. It looked like the assigned heading would take us directly to the heatt intersection which was where the radials crossed. The controller then gave us a pilot's discretion clearance to cross heatt at 11000 ft. At the time we were at 17000 ft. The captain started a slow descent (500 FPM). After passing 13000 ft MSL, it appeared we had about another 10 mi until the intersection. I suggested to the captain that we increase the rate of descent in order to cross heatt at 11000 ft. According to the visual depiction on the EFIS, we had not joined either the 162 degree radial off vrb or the 198 degree radial into vkz. About that time the controller called us saying that he showed us at heatt intersection. According to our depiction, we still had several mi to go. I told him that we were not at heatt yet. He asked us for our DME off of vrz. That DME distance indicated that we were at heatt intersection. I believe that we were bit by the routine bug. We have crossed that intersection so many times before and it was so routine that we didn't double check the DME distance with the visual depiction on the EFIS. Also contributing to this incident was my being off radio getting the mia ATIS and contacting the company with an in-range call. Both of us should have monitored our position more accurately than we were. Again, don't let the routine become routine.

Title: FLC OF AN LTT UNDERSHOT A DSCNT XING RESTR.

Narrative: FROM JAX TO MIA ON OCT/SAT/95 WE WERE GIVEN A HDG TO INTERCEPT THE HEATTY ARR SE OF VRB (WHICH CONSISTS OF THE 162 RADIAL OFF VRB). ON OUR EFIS DISPLAY THE 162 RADIAL WAS SET UP ON THE CAPT'S SIDE AND THE INBOUND RADIAL (THE 198 RADIAL TO VKZ) WAS SET UP ON MY SIDE. BOTH DISPLAYS SHOWED BOTH RADIALS SUPERIMPOSED ON THEM. IT LOOKED LIKE THE ASSIGNED HDG WOULD TAKE US DIRECTLY TO THE HEATT INTXN WHICH WAS WHERE THE RADIALS CROSSED. THE CTLR THEN GAVE US A PLT'S DISCRETION CLRNC TO CROSS HEATT AT 11000 FT. AT THE TIME WE WERE AT 17000 FT. THE CAPT STARTED A SLOW DSCNT (500 FPM). AFTER PASSING 13000 FT MSL, IT APPEARED WE HAD ABOUT ANOTHER 10 MI UNTIL THE INTXN. I SUGGESTED TO THE CAPT THAT WE INCREASE THE RATE OF DSCNT IN ORDER TO CROSS HEATT AT 11000 FT. ACCORDING TO THE VISUAL DEPICTION ON THE EFIS, WE HAD NOT JOINED EITHER THE 162 DEG RADIAL OFF VRB OR THE 198 DEG RADIAL INTO VKZ. ABOUT THAT TIME THE CTLR CALLED US SAYING THAT HE SHOWED US AT HEATT INTXN. ACCORDING TO OUR DEPICTION, WE STILL HAD SEVERAL MI TO GO. I TOLD HIM THAT WE WERE NOT AT HEATT YET. HE ASKED US FOR OUR DME OFF OF VRZ. THAT DME DISTANCE INDICATED THAT WE WERE AT HEATT INTXN. I BELIEVE THAT WE WERE BIT BY THE ROUTINE BUG. WE HAVE CROSSED THAT INTXN SO MANY TIMES BEFORE AND IT WAS SO ROUTINE THAT WE DIDN'T DOUBLE CHK THE DME DISTANCE WITH THE VISUAL DEPICTION ON THE EFIS. ALSO CONTRIBUTING TO THIS INCIDENT WAS MY BEING OFF RADIO GETTING THE MIA ATIS AND CONTACTING THE COMPANY WITH AN IN-RANGE CALL. BOTH OF US SHOULD HAVE MONITORED OUR POS MORE ACCURATELY THAN WE WERE. AGAIN, DON'T LET THE ROUTINE BECOME ROUTINE.
