Narrative:

This was an instrument training flight, we were on a partial panel NDB approach to an NDB located on the airport at bremerton, wa, approaching runway 1 (439 MSL) from the south. There is a hill with towers, tops at 2395 MSL, about 2 mi northwest of the field. We began our missed approach in IMC conditions right over the field slightly west of runway 1 and were climbing to 2000 ft while doing a timed turn to an eastbound heading. We were in the turn and passing through approximately 1500 MSL when seattle approach asked us what heading we were on. We were still turning at the time, so I took the controls and was in the process of leveling the wings to get a compass reading when approach gave us an 'immediate' turn to the right to an easterly or southeasterly heading (I no longer remember the heading). While I was cranking in a hard turn to the right, my instrument student uncovered the heading indicator so that we could turn to the exact heading in a hurry, which we did. My student and I discussed the situation afterward, and we surmise that, being on partial panel, a cockpit distraction may have caused us to overshoot the rollout on our turn to the missed approach heading, and the overshoot, combined with a southeast wind, may have caused a radar ground track showing us approaching the hill to the northwest -- the reason for the 'immediate turn requested by approach.

Title: HDG TRACK DEV PRODUCES A PROX TO GND SITUATION FOR SMA PLTS.

Narrative: THIS WAS AN INST TRAINING FLT, WE WERE ON A PARTIAL PANEL NDB APCH TO AN NDB LOCATED ON THE ARPT AT BREMERTON, WA, APCHING RWY 1 (439 MSL) FROM THE S. THERE IS A HILL WITH TWRS, TOPS AT 2395 MSL, ABOUT 2 MI NW OF THE FIELD. WE BEGAN OUR MISSED APCH IN IMC CONDITIONS R OVER THE FIELD SLIGHTLY W OF RWY 1 AND WERE CLBING TO 2000 FT WHILE DOING A TIMED TURN TO AN EBOUND HDG. WE WERE IN THE TURN AND PASSING THROUGH APPROX 1500 MSL WHEN SEATTLE APCH ASKED US WHAT HDG WE WERE ON. WE WERE STILL TURNING AT THE TIME, SO I TOOK THE CTLS AND WAS IN THE PROCESS OF LEVELING THE WINGS TO GET A COMPASS READING WHEN APCH GAVE US AN 'IMMEDIATE' TURN TO THE R TO AN EASTERLY OR SOUTHEASTERLY HDG (I NO LONGER REMEMBER THE HDG). WHILE I WAS CRANKING IN A HARD TURN TO THE R, MY INST STUDENT UNCOVERED THE HDG INDICATOR SO THAT WE COULD TURN TO THE EXACT HDG IN A HURRY, WHICH WE DID. MY STUDENT AND I DISCUSSED THE SITUATION AFTERWARD, AND WE SURMISE THAT, BEING ON PARTIAL PANEL, A COCKPIT DISTR MAY HAVE CAUSED US TO OVERSHOOT THE ROLLOUT ON OUR TURN TO THE MISSED APCH HDG, AND THE OVERSHOOT, COMBINED WITH A SE WIND, MAY HAVE CAUSED A RADAR GND TRACK SHOWING US APCHING THE HILL TO THE NW -- THE REASON FOR THE 'IMMEDIATE TURN REQUESTED BY APCH.
