Narrative:
During takeoff roll, above 90 KTS IAS, I discovered I had no airspeed indication. (I determined my airspeed by looking at the copilot's indicator). Choosing not to risk a high speed abort, I continued takeoff and when safely airborne, I transferred aircraft control to the copilot. When above 15000 ft MSL (in mountainous terrain) in a stabilized climb we addressed the problem (which also included my altitude and vsi), as a crew, using abnormal procedures from the pilot's operating manual. After several attempts to resolve problem, to no avail, we contacted company flight control (dispatch) and maintenance control via company radio. I described problem as a failure of captain's pitot-static instruments. My standby airspeed and altitude showed normal indications and exactly matched the copilot's instruments. We were now 45 mins to 1 hour into the flight. I made the decision to continue to the destination (dallas/ft. Worth) approximately 1 1/2 hours away where the WX was good. We were in VMC for the entire flight and made a normal approach and landing at the destination with the copilot flying. At no time during the flight did I feel that the safety of the flight was in jeopardy.
Original NASA ASRS Text
Title: AN MLG ACR CREW HAD A FAILURE OF THE CAPT'S PITOT-STATIC SYS ON TKOF.
Narrative: DURING TKOF ROLL, ABOVE 90 KTS IAS, I DISCOVERED I HAD NO AIRSPD INDICATION. (I DETERMINED MY AIRSPD BY LOOKING AT THE COPLT'S INDICATOR). CHOOSING NOT TO RISK A HIGH SPD ABORT, I CONTINUED TKOF AND WHEN SAFELY AIRBORNE, I TRANSFERRED ACFT CTL TO THE COPLT. WHEN ABOVE 15000 FT MSL (IN MOUNTAINOUS TERRAIN) IN A STABILIZED CLB WE ADDRESSED THE PROBLEM (WHICH ALSO INCLUDED MY ALT AND VSI), AS A CREW, USING ABNORMAL PROCS FROM THE PLT'S OPERATING MANUAL. AFTER SEVERAL ATTEMPTS TO RESOLVE PROBLEM, TO NO AVAIL, WE CONTACTED COMPANY FLT CTL (DISPATCH) AND MAINT CTL VIA COMPANY RADIO. I DESCRIBED PROBLEM AS A FAILURE OF CAPT'S PITOT-STATIC INSTS. MY STANDBY AIRSPD AND ALT SHOWED NORMAL INDICATIONS AND EXACTLY MATCHED THE COPLT'S INSTS. WE WERE NOW 45 MINS TO 1 HR INTO THE FLT. I MADE THE DECISION TO CONTINUE TO THE DEST (DALLAS/FT. WORTH) APPROX 1 1/2 HRS AWAY WHERE THE WX WAS GOOD. WE WERE IN VMC FOR THE ENTIRE FLT AND MADE A NORMAL APCH AND LNDG AT THE DEST WITH THE COPLT FLYING. AT NO TIME DURING THE FLT DID I FEEL THAT THE SAFETY OF THE FLT WAS IN JEOPARDY.
