Narrative

WE WERE ON A LEFT DOWNWIND FOR RWY 14R WHEN TWR ADVISED US THAT WE WERE NUMBER TWO FOR THE RWY FOLLOWING A JETSTREAM ON FOUR MILE FINAL. I SPOTTED THE JETSTREAM AND ADVISED TOWER THAT I HAD MY TFC IN SIGHT AND WOULD FOLLOW THAT TFC. KNOWING THAT THE JETSTREAM WOULD BE PRODUCING WAKE TURB; I PLANNED TO STAY ABOVE ITS FLT PATH AND LAND BEYOND ITS TOUCHDOWN POINT. AS IT PASSED BY OUR LEFT SIDE; I STARTED MY TURN TO BASE; STAYING ABOVE ITS FLT PATH. ON MY BASE AND TURN TO FINAL; I WATCHED THE JETSTREAM TO DETERMINE ITS TOUCHDOWN POINT; I COULD TOUCHDOWN BEYOND THAT POINT. WHEN WE WERE ON FINAL; TOWER CLRED US TO LAND RWY 14R; HOLD SHORT RWY 22R. I READ BACK THAT WE WERE CLRED TO LAND RWY 14R; HOLD SHORT OF RWY 22R. NOW I HAD TO TOUCHDOWN BEYOND THE JETSTREAM'S TOUCHDOWN POINT AND HOLD SHORT OF RWY 22R. I DETERMINED THAT I SHOULD TOUCHDOWN AT OR BEYOND THE FIXED DIST MARKERS TO BE SAFE OF THE WAKE TURB; AND STILL BE ABLE TO HOLD SHORT OF RWY 22R. AS WE CROSSED THE FIXED DIST MARKERS; I BEGAN TO ROUND OUT FOR TOUCHDOWN. THE PLANE FLOATED IN GND EFFECT LONGER THAN EXPECTED; THEN WHEN WE TOUCHED DOWN; THE PLANE BOUNCED AN BECAME AIRBORNE AGAIN. AT THIS POINT; THE INSTRUCTOR PROMPTED ME TO GAR; SO I APPLIED FULL PWR AND EXECUTED A GAR. AS I DID THIS; THE INSTRUCTOR NOTIFIED TOWER THAT WE WERE GOING AROUND. THE TWR THEN NOTIFIED THE ACFT LNDG ON RWY 22R; THAT THEIR TFC ON RWY 14R WAS GOING AROUND. THIS COULD HAVE BEEN AVOIDED HAD I NOT ACCEPTED THE LAND AND HOLD SHORT CLRNC.
