SMA HAS BLOCKED PITOT TUBE; NO AIRSPD INDICATOR. RETURN LAND WITH CLOSE PROX OF LTT.

Narrative

AFTER TKOF; NOTICING THAT THE AIRSPD INDICATOR WAS NOT RESPONDING ACCURATELY; WE PROCEEDED ON A 'NORMAL' TFC PATTERN; SOMEWHAT PREOCCUPIED WITH AIRSPD INDICATIONS AND A 'NEW STUDENT.' PROCEEDED DOWNWIND. TWR CALLED THE LTT AND WE HAD HIM IN PLAIN SIGHT; BOTH OF US. WE MISSED A CONFIRMATION OF 'CLRED TO LAND' BY (PROBABLY PREOCCUPATION) TWR'S CONFIRMING OUR 'THIS WILL BE A FULL STOP.' WE TURNED TO BASE; AND TWR SAID WE WERE #2 BEHIND AN SMA SO; WE TURNED BACK TO DOWNWIND. I DIDN'T NOTE THAT WE HAD ALSO NOT CORRECTED FOR THE INITIAL TURN IN. BY THE TIME WE DID TURN OUR BASE; WE HAD LESS ROOM THAN NORMAL (BECAUSE OF THE RETURN TO DOWNWIND). THE LTT IS OF COURSE APCHING AND I TOOK THE CTLS TO HELP TIGHTEN THE TURN OUT OF THE WAY. THE LTT DID NOT APPEAR TO MAKE/TAKE ANY ACTIONS TO AVOID US; BUT QUERIED THE TWR AS TO OUR INTENTIONS. AS A CFI; I CERTAINLY WILL KEEP A BETTER MIND ON FLYING THE AIRPLANE FIRST; ITS SPATIAL POSITIONING AND WHAT'S BEING SAID OVER THE RADIOS; KEEPING THE 'BIG PICTURE' CLRLY IN MIND. WORK ON NOT ALLOWING PLTS WITH MORE EXPERIENCE TO INTIMIDATE MY DECISIVENESS. SUPPLEMENTAL INFO FROM ACN 194252: I FREQUENTLY COUNSEL NEW CFI'S NOT TO LET ANYONE INTIMIDATE THEM -- NO MATTER WHAT THE PERSON'S PROFESSIONAL STATURE OR EXPERIENCE. PERHAPS MY CONSIDERABLE EXPERIENCE CAUSED THE RELATIVELY LOW TIME CFI NOT TO TAKE COMMAND OF THE ACFT SOONER; BEFORE WE OVERSHOT R29. FROM NOW ON; I AM SURE SHE WILL.
