Narrative:
After takeoff, noticing that the airspeed indicator was not responding accurately, we proceeded on a 'normal' traffic pattern, somewhat preoccupied with airspeed indications and a 'new student.' proceeded downwind. Tower called the light transport and we had him in plain sight, both of us. We missed a confirmation of 'cleared to land' by (probably preoccupation) tower's confirming our 'this will be a full stop.' we turned to base, and tower said we were #2 behind an small aircraft 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 light transport is of course approaching and I took the controls to help tighten the turn out of the way. The light transport did not appear to make/take any actions to avoid us, but queried the tower 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' clearly in mind. Work on not allowing pilots with more experience to intimidate my decisiveness. Supplemental information 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 aircraft sooner, before we overshot R29. From now on, I am sure she will.

Title: 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.
