Narrative:

As I went up to cockpit to prepare for departure bda-atl my stomach felt little unsettled and I took an over the counter tablet. Departed bda XA30 ast. About 1 hour 15 mins into flight, I became very nauseous and felt I was going to get sick at my stomach. I started to tell the copilot I didn't feel well and passed out for about 30 seconds. He put me on oxygen and felt ok for bout 25 mins. When off oxygen, I passed out again for about 10 seconds. I stayed on oxygen until lower altitude and felt fine rest of flight. Copilot took control of aircraft and was very capable and confident. After the 2 incidents, I felt fine rest of flight and fully alert and capable of performing my duties. The flight progressed normally until approximately XA45 when captain asked flight attendant for an over the counter tablet and some water. I asked captain if he was feeling ok, to which he responded that his stomach had been unsettled and that he had already taken a couple of other over the counter tablets. Flight attendant brought up the tablets along with a tray of food for myself. Approximately ten mins later, flight attendant came to the cockpit to situation down for a couple of mins and to retrieve my tray. At this time, we were approximately 50-80 mi east of chs. After talking with him for several mins, I heard captain mumble that he was feeling dizzy. I immediately looked at him and noticed that his eyelids were blinking rapidly and that he didn't seem to be focused on anything. I asked captain if he was ok. He didn't respond. I then noticed his right hand drawing up towards his body as his shoulders slumped forward. His hand began to rotate from side to side and his head began to droop. Almost immediately his body relaxed completely and he appeared to pass out. His body leaned over the center console. I immediately moved my seat backwards and unhooked my seat belt in order to assist him. I moved his seat to the full aft position while raising him to an upright position. Flight attendant rose from the jump seat and started to open the cockpit door when I asked him to grab captain's oxygen mask from the side console. I had to explain to him where it was and how to activate it which he then proceeded to do while I held captain in an upright position. I then placed the mask over the captain and within seconds he began to become more alert. His eyes opened and had a dazed look. I then began to question him as to how he felt. He responded that he felt better and that he thought he had just nodded off. I told him that he had passed out. I then told him to situation back, relax, and just continue breathing the oxygen for awhile. I continued to quiz him on his condition and he continued to respond affirmatively. Once he became alert, I asked him if he felt that he required immediate medical attention. He felt immediate medical attention was unnecessary, but expressed concert for the aircraft and requested that I continue flying. I told him that I had control and would take care of everything. We continued on towards atl without further incident. I increased the speed during the remainder of cruise and throughout our descent. I received the ATIS and briefed the approach for atl. I independently completed the descent and approach checklists by reading them aloud. Captain followed along by setting his airspeed bugs and altimeter setting. There were no other aircraft in the immediate vicinity and no aircraft on the approach in front of us. I made all control movements (flaps, gear, etc.) on the rapid descent to a visual approach to runway 9R. Touchdown and rollout were normal. Throughout this time, I verbalized my actions to captain so as to keep him informed as to flight status. I taxied the aircraft clear of runway 9R using the hi speed taxiway and rudder pedal steering while slowing the aircraft. Captain indicated that he could taxi the aircraft to the gate. With no other aircraft in the immediate vicinity, I decided to let him take us to the gate. I followed his movements ad kept my feet in a position to stop the aircraft should it become necessary. We proceeded to gate normally whereupon passenger deplaned. I walked with captain throughout the terminal and downstairs to the chief pilot's office where we relayed the incident to captain X. Captain called his FAA doctor for an immediate appointment. I escorted him to the doctor's office and spoke with doctor. Upon examination of captain, doctor referred him to university clinic where additional tests would be performed. I returned home after dricing captain to clinic where his wife was subsequently meeting him.

Title: CAPT OF AN LGT BECAME INCAPACITATED FOR SHORT PERIODS, AT CRUISE ALT AND USED OXYGEN TO BECOME REVIVED.

Narrative: AS I WENT UP TO COCKPIT TO PREPARE FOR DEP BDA-ATL MY STOMACH FELT LITTLE UNSETTLED AND I TOOK AN OVER THE COUNTER TABLET. DEPARTED BDA XA30 AST. ABOUT 1 HR 15 MINS INTO FLT, I BECAME VERY NAUSEOUS AND FELT I WAS GOING TO GET SICK AT MY STOMACH. I STARTED TO TELL THE COPLT I DIDN'T FEEL WELL AND PASSED OUT FOR ABOUT 30 SECONDS. HE PUT ME ON OXYGEN AND FELT OK FOR BOUT 25 MINS. WHEN OFF OXYGEN, I PASSED OUT AGAIN FOR ABOUT 10 SECONDS. I STAYED ON OXYGEN UNTIL LOWER ALT AND FELT FINE REST OF FLT. COPLT TOOK CTL OF ACFT AND WAS VERY CAPABLE AND CONFIDENT. AFTER THE 2 INCIDENTS, I FELT FINE REST OF FLT AND FULLY ALERT AND CAPABLE OF PERFORMING MY DUTIES. THE FLT PROGRESSED NORMALLY UNTIL APPROX XA45 WHEN CAPT ASKED FLT ATTENDANT FOR AN OVER THE COUNTER TABLET AND SOME WATER. I ASKED CAPT IF HE WAS FEELING OK, TO WHICH HE RESPONDED THAT HIS STOMACH HAD BEEN UNSETTLED AND THAT HE HAD ALREADY TAKEN A COUPLE OF OTHER OVER THE COUNTER TABLETS. FLT ATTENDANT BROUGHT UP THE TABLETS ALONG WITH A TRAY OF FOOD FOR MYSELF. APPROX TEN MINS LATER, FLT ATTENDANT CAME TO THE COCKPIT TO SIT DOWN FOR A COUPLE OF MINS AND TO RETRIEVE MY TRAY. AT THIS TIME, WE WERE APPROX 50-80 MI E OF CHS. AFTER TALKING WITH HIM FOR SEVERAL MINS, I HEARD CAPT MUMBLE THAT HE WAS FEELING DIZZY. I IMMEDIATELY LOOKED AT HIM AND NOTICED THAT HIS EYELIDS WERE BLINKING RAPIDLY AND THAT HE DIDN'T SEEM TO BE FOCUSED ON ANYTHING. I ASKED CAPT IF HE WAS OK. HE DIDN'T RESPOND.

I IMMEDIATELY MOVED MY SEAT BACKWARDS AND UNHOOKED MY SEAT BELT IN ORDER TO ASSIST HIM. I MOVED HIS SEAT TO THE FULL AFT POS WHILE RAISING HIM TO AN UPRIGHT POS. FLT ATTENDANT ROSE FROM THE JUMP SEAT AND STARTED TO OPEN THE COCKPIT DOOR WHEN I ASKED HIM TO GRAB CAPT'S OXYGEN MASK FROM THE SIDE CONSOLE. I HAD TO EXPLAIN TO HIM WHERE IT WAS AND HOW TO ACTIVATE IT WHICH HE THEN PROCEEDED TO DO WHILE I HELD CAPT IN AN UPRIGHT POSITION. I THEN PLACED THE MASK OVER THE CAPT AND WITHIN SECONDS HE BEGAN TO BECOME MORE ALERT. HIS EYES OPENED AND HAD A DAZED LOOK. I THEN BEGAN TO QUESTION HIM AS TO HOW HE FELT.

HE FELT IMMEDIATE MEDICAL ATTENTION WAS UNNECESSARY, BUT EXPRESSED CONCERT FOR THE ACFT AND REQUESTED THAT I CONTINUE FLYING. I TOLD HIM THAT I HAD CONTROL AND WOULD TAKE CARE OF EVERYTHING. WE CONTINUED ON TOWARDS ATL WITHOUT FURTHER INCIDENT. I INCREASED THE SPD DURING THE REMAINDER OF CRUISE AND THROUGHOUT OUR DSCNT. I RECEIVED THE ATIS AND BRIEFED THE APCH FOR ATL. I INDEPENDENTLY COMPLETED THE DSCNT AND APCH CHKLISTS BY READING THEM ALOUD. CAPT FOLLOWED ALONG BY SETTING HIS AIRSPD BUGS AND ALTIMETER SETTING. THERE WERE NO OTHER ACFT IN THE IMMEDIATE VICINITY AND NO ACFT ON THE APCH IN FRONT OF US. I MADE ALL CTL MOVEMENTS (FLAPS, GEAR, ETC.) ON THE RAPID DSCNT TO A VISUAL APCH TO RWY 9R. TOUCHDOWN AND ROLLOUT WERE NORMAL. THROUGHOUT THIS TIME, I VERBALIZED MY ACTIONS TO CAPT SO AS TO KEEP HIM INFORMED AS TO FLT STATUS. I TAXIED THE ACFT CLR OF RWY 9R USING THE HI SPD TXWY AND RUDDER PEDAL STEERING WHILE SLOWING THE ACFT. CAPT INDICATED THAT HE COULD TAXI THE ACFT TO THE GATE. WITH NO OTHER ACFT IN THE IMMEDIATE VICINITY, I DECIDED TO LET HIM TAKE US TO THE GATE. I FOLLOWED HIS MOVEMENTS AD KEPT MY FEET IN A POS TO STOP THE ACFT SHOULD IT BECOME NECESSARY.
