Narrative

FO SHOOTING ILS RWY 32 APCH. WE WERE CLRED FOR APCH. HE LEVELED OFF AT 5500 FT INBOUND FROM PROC TURN; DURING FLAP EXTENSION. HE WAS HAND FLYING THE AIRPLANE. HE LET THE AIRPLANE BEGIN TO CLB. I CALLED THIS TO HIS ATTN AND HE LEVELED OFF AND STARTED DOWN. I LOOKED AWAY AGAIN AND WHEN I LOOKED BACK THE AIRPLANE WAS CLBING AGAIN. I AGAIN CALLED THIS TO HIS ATTN; AND HE STARTED DOWN. TOTAL DEV WAS PLUS 500 FT. I HAVE NO EXPLANATION FOR HIS FLYING PROBS. HE MUST HAVE BEEN TIRED OR NERVOUS ABOUT THE UPCOMING LNDG ON AN ICY RUNWAY WITH A 15 KTS XWIND. IN THE FUTURE; I PLAN TO MAKE OR FLY ALL DIFFICULT APCHS UNTIL I GET TO KNOW THE ABILITIES OF THE FO BETTER. NO MORE ASSUMING HE (SHE) IS UP TO AN APCH IN DIFFICULT CIRCUMSTANCES UNTIL WE HAVE FLOWN TOGETHER FOR AWHILE. IT IS NOT UNUSUAL FOR ME TO FLY WITH A DIFFERENT FO EVERY TRIP. I WOULD FLY A 4 DAY SERIES OF FLTS WITH THE SAME PERSON; THEN THE NEXT WEEK SEE A DIFFERENT FO ON THE NEXT 4 DAY TRIP. FROM NOW ON WE ARE GOING TO HAVE TO FLY TOGETHER UNTIL I AM COMFORTABLE THE FO IS READY FOR THE APCH. NO MORE ASSUMING BECAUSE HE IS IN THE SEAT AND QUALIFIED THAT HE IS READY TO FLY A DIFFICULT APCH OR LNDG.
