Narrative:

Falcon called on 3 mi final for runway 16R. Initial call was on east side tower frequency 6 mi out. Aircraft are required to call 10 mi northwest when they are jet aircraft according to LOA with ZSE. At the time I had pattern touch and go traffic with itinerants. We do have tardis which is a radar display, but the FAA refuses to certify it, therefore it is useful as electronic binoculars only. I observed the beacon code and adjusted the other traffic to accommodate the fast moving arrival. No conflict due to the tardis. Callback conversation with reporter revealed the following information: reporter stated they have class D airspace that is 5 mi in diameter and extends up to 3100 ft MSL. The tardis radar has been installed for approximately 1 yr and is a 17 inch pc type display. Reporter said two are installed in the ceiling of the tower and considers them very good however, they are not yet certified for use. An agreement with ZSE requires that IFR inbound jet traffic must be turned over to the tower at 10 mi or 7 mi if slower type aircraft making practice approachs. Reporter feels some ARTCC controllers do not adhere to the letter which at times causes congestion at the airport.

Title: ATCT CTLR AT PAE CLAIMS ZSE SWITCHES INBOUND IFR TFC TO THE TWR VERY CLOSE TO THE ARPT. APPARENTLY IT CREATES PROBS WHEN THE LCL CTLR IS BUSY WITH VFR TFC IN THE PATTERN. CTLR ALSO STATED THAT THE TARDIS RADAR IS VERY GOOD BUT IS DIFFICULT TO USE WHEN THE POS IS BUSY.

Narrative: FALCON CALLED ON 3 MI FINAL FOR RWY 16R. INITIAL CALL WAS ON E SIDE TWR FREQ 6 MI OUT. ACFT ARE REQUIRED TO CALL 10 MI NW WHEN THEY ARE JET ACFT ACCORDING TO LOA WITH ZSE. AT THE TIME I HAD PATTERN TOUCH AND GO TFC WITH ITINERANTS. WE DO HAVE TARDIS WHICH IS A RADAR DISPLAY, BUT THE FAA REFUSES TO CERTIFY IT, THEREFORE IT IS USEFUL AS ELECTRONIC BINOCULARS ONLY. I OBSERVED THE BEACON CODE AND ADJUSTED THE OTHER TFC TO ACCOMMODATE THE FAST MOVING ARR. NO CONFLICT DUE TO THE TARDIS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THEY HAVE CLASS D AIRSPACE THAT IS 5 MI IN DIAMETER AND EXTENDS UP TO 3100 FT MSL. THE TARDIS RADAR HAS BEEN INSTALLED FOR APPROX 1 YR AND IS A 17 INCH PC TYPE DISPLAY. RPTR SAID TWO ARE INSTALLED IN THE CEILING OF THE TWR AND CONSIDERS THEM VERY GOOD HOWEVER, THEY ARE NOT YET CERTIFIED FOR USE. AN AGREEMENT WITH ZSE REQUIRES THAT IFR INBOUND JET TFC MUST BE TURNED OVER TO THE TWR AT 10 MI OR 7 MI IF SLOWER TYPE ACFT MAKING PRACTICE APCHS. RPTR FEELS SOME ARTCC CTLRS DO NOT ADHERE TO THE LETTER WHICH AT TIMES CAUSES CONGESTION AT THE ARPT.
