Narrative:

I taxied onto a runway that had just been activated, but no aircraft had yet landed, taken off, or come in close proximity in either mode. I had taxi clearance to that runway, but not to enter. I had received two taxi clrncs to the same runway. The first was unusual in that (as I recall) a taxiway was specified. In the case of runway 17 there are two options: taxiway a and taxiway B which parallel runway 17/35 on either side. Under 'a clearance to is not a clearance onto' the only route is obvious. A second clearance was subsequently issued to exit the ramp to the north and taxi via a series of 2 txwys. The controller then proceeded to sort out a conflict between aircraft on and entering the ramp, no longer on the maneuvering area. The resulting chatter made supervising the student who was taxiing exceedingly difficult. The second clearance exacerbated that problem by requiring two 120 degree turns, in opposite directions, in rapid succession and in close proximity to warning lights protecting a celiometer. By the time we entered the first taxiway a change of controller had occurred and debates/negotiations were in progress in regard to the runway change. In an attempt to demonstrate I was blocked from communicating I missed the turn to the second taxiway and entered runway 17.

Title: RWY INCURSION AT SEE, CA, DURING A RWY AND TAXI CLRNC CHANGE BY AN INSTRUCTOR PLT ON A TRAINING FLT.

Narrative: I TAXIED ONTO A RWY THAT HAD JUST BEEN ACTIVATED, BUT NO ACFT HAD YET LANDED, TAKEN OFF, OR COME IN CLOSE PROX IN EITHER MODE. I HAD TAXI CLRNC TO THAT RWY, BUT NOT TO ENTER. I HAD RECEIVED TWO TAXI CLRNCS TO THE SAME RWY. THE FIRST WAS UNUSUAL IN THAT (AS I RECALL) A TXWY WAS SPECIFIED. IN THE CASE OF RWY 17 THERE ARE TWO OPTIONS: TXWY A AND TXWY B WHICH PARALLEL RWY 17/35 ON EITHER SIDE. UNDER 'A CLRNC TO IS NOT A CLRNC ONTO' THE ONLY RTE IS OBVIOUS. A SECOND CLRNC WAS SUBSEQUENTLY ISSUED TO EXIT THE RAMP TO THE N AND TAXI VIA A SERIES OF 2 TXWYS. THE CTLR THEN PROCEEDED TO SORT OUT A CONFLICT BTWN ACFT ON AND ENTERING THE RAMP, NO LONGER ON THE MANEUVERING AREA. THE RESULTING CHATTER MADE SUPERVISING THE STUDENT WHO WAS TAXIING EXCEEDINGLY DIFFICULT. THE SECOND CLRNC EXACERBATED THAT PROB BY REQUIRING TWO 120 DEG TURNS, IN OPPOSITE DIRECTIONS, IN RAPID SUCCESSION AND IN CLOSE PROX TO WARNING LIGHTS PROTECTING A CELIOMETER. BY THE TIME WE ENTERED THE FIRST TXWY A CHANGE OF CTLR HAD OCCURRED AND DEBATES/NEGOTIATIONS WERE IN PROGRESS IN REGARD TO THE RWY CHANGE. IN AN ATTEMPT TO DEMONSTRATE I WAS BLOCKED FROM COMMUNICATING I MISSED THE TURN TO THE SECOND TXWY AND ENTERED RWY 17.
