Narrative:

On the second leg of trip; we were departing [the airport on the SID]. After passing approximately FL190 in a right turn we hit what felt like light turbulence and got an aural and visual master caution warning and the stick shaker activated continuously along with the autopilot and auto throttles kicking off. The ead (engine and alert display) showed a level 2 aoa (angle of attack) left heat failure and wind shear detect failure. The flight director pitch indicator went away and elevator feel select manual was displayed. The fcp (flight control panel) also was all dashes except for the heading and would not accept any input.we notified center we were having instrument problems and asked for a heading and we would keep them advised. They cleared us to FL350 while we worked the problem. Upon reaching FL350; the captain and I noticed the airspeed and altitude comparator displayed on our pfd (primary flight display). Center asked what our altitude showed and I referenced the standby instruments and the captain`s instruments along with what ATC was reading and we realized that the captain displays were bad and the first officer were still good. The captain selected flight director on 2 and CADC (central air data computer) on 2 and we then asked ATC to descend us to FL270 to get us out of rvsm airspace and the captain called for the airspeed unreliable checklist in the QRH. After following the QRH checklist; we were able to get the autopilot 2 and fcp back but the stick shaker remained on continuously until landing along with the captain airspeed red and the aoa in the HUD stayed reading 25 degrees nose up. We requested direct to [destination] and flew the RNAV runway 29 for a visual approach flaps 35. We backed up the pitch and airspeed with pitch and power settings from the QRH and made an uneventful landing. Upon leaving the aircraft; I checked the left side of the aircraft and noticed the captain aoa vane was missing and notified maintenance.
