Narrative:

This commentary concerns the events of a flight upon which I acted as a first officer during my first trip on IOE. Once we had arrived on our inbound flight, I performed the walkaround (postflt/preflight) and noted no abnormalities. I copied our ATIS, received our clearance, set the v-spds, determined our thrust settings and maximum takeoff weight based on the projected and current runway in use (over 10000 ft long). Once all paperwork was done, clearance was received to taxi to the longer runway upon which the captain requested a nearer and shorter runway (5600 ft). I questioned the use of the runway due to high temperature (outside air temperature), aircraft loading, and the fact that performance numbers had not been calculated for the shorter runway. The captain forged ahead in spite of my continued objections and proceeded to attempt a takeoff on the shorter runway. As we accelerated down the runway, and I called out the airspeed, the captain wisely decided to abort. He successfully rejected the takeoff and taxied clear of the runway. As a result of the rejected takeoff the brake temperatures were hot and I notified the captain that we would need to hold in position on the ramp to allow the brakes to cool before a second takeoff could be made. About 30 seconds later, I asked the captain if he would like me to contact ground to request a place to hold. He said 'no' and that we would take off immediately. I objected 3-4 times stating that I did not think we should attempt the takeoff due to high brake temperatures, lack of cooling, effect on the tires, and what the effect would be on a second rejected takeoff. At this point the captain chose to ignore my objections. He took off and the flight proceeded normally to our destination. In summary, the captain used poor judgement and in spite of repeated objections by myself, attempted a takeoff on a runway which was too short for the current conditions. He then successfully completed a rejected takeoff and then took off on the longer and appropriate runway with high brake temperatures without the mandatory cooling times as stated in the flight manual. The captain ignored my input and seemed intent on using bad judgement in spite of obvious safety considerations. I and my strong objections. It seemed that the captain became a 1-MAN crew and proper CRM stopped.

Title: A CANADAIR CL65 REJECTED TKOF ON A SHORT RWY WITH A HIGH ENERGY STOP. MADE SECOND TKOF FROM LONGER RWY WITHOUT BRAKE COOLING.

Narrative: THIS COMMENTARY CONCERNS THE EVENTS OF A FLT UPON WHICH I ACTED AS A FO DURING MY FIRST TRIP ON IOE. ONCE WE HAD ARRIVED ON OUR INBOUND FLT, I PERFORMED THE WALKAROUND (POSTFLT/PREFLT) AND NOTED NO ABNORMALITIES. I COPIED OUR ATIS, RECEIVED OUR CLRNC, SET THE V-SPDS, DETERMINED OUR THRUST SETTINGS AND MAX TKOF WT BASED ON THE PROJECTED AND CURRENT RWY IN USE (OVER 10000 FT LONG). ONCE ALL PAPERWORK WAS DONE, CLRNC WAS RECEIVED TO TAXI TO THE LONGER RWY UPON WHICH THE CAPT REQUESTED A NEARER AND SHORTER RWY (5600 FT). I QUESTIONED THE USE OF THE RWY DUE TO HIGH TEMP (OUTSIDE AIR TEMP), ACFT LOADING, AND THE FACT THAT PERFORMANCE NUMBERS HAD NOT BEEN CALCULATED FOR THE SHORTER RWY. THE CAPT FORGED AHEAD IN SPITE OF MY CONTINUED OBJECTIONS AND PROCEEDED TO ATTEMPT A TKOF ON THE SHORTER RWY. AS WE ACCELERATED DOWN THE RWY, AND I CALLED OUT THE AIRSPD, THE CAPT WISELY DECIDED TO ABORT. HE SUCCESSFULLY REJECTED THE TKOF AND TAXIED CLR OF THE RWY. AS A RESULT OF THE REJECTED TKOF THE BRAKE TEMPS WERE HOT AND I NOTIFIED THE CAPT THAT WE WOULD NEED TO HOLD IN POS ON THE RAMP TO ALLOW THE BRAKES TO COOL BEFORE A SECOND TKOF COULD BE MADE. ABOUT 30 SECONDS LATER, I ASKED THE CAPT IF HE WOULD LIKE ME TO CONTACT GND TO REQUEST A PLACE TO HOLD. HE SAID 'NO' AND THAT WE WOULD TAKE OFF IMMEDIATELY. I OBJECTED 3-4 TIMES STATING THAT I DID NOT THINK WE SHOULD ATTEMPT THE TKOF DUE TO HIGH BRAKE TEMPS, LACK OF COOLING, EFFECT ON THE TIRES, AND WHAT THE EFFECT WOULD BE ON A SECOND REJECTED TKOF. AT THIS POINT THE CAPT CHOSE TO IGNORE MY OBJECTIONS. HE TOOK OFF AND THE FLT PROCEEDED NORMALLY TO OUR DEST. IN SUMMARY, THE CAPT USED POOR JUDGEMENT AND IN SPITE OF REPEATED OBJECTIONS BY MYSELF, ATTEMPTED A TKOF ON A RWY WHICH WAS TOO SHORT FOR THE CURRENT CONDITIONS. HE THEN SUCCESSFULLY COMPLETED A REJECTED TKOF AND THEN TOOK OFF ON THE LONGER AND APPROPRIATE RWY WITH HIGH BRAKE TEMPS WITHOUT THE MANDATORY COOLING TIMES AS STATED IN THE FLT MANUAL. THE CAPT IGNORED MY INPUT AND SEEMED INTENT ON USING BAD JUDGEMENT IN SPITE OF OBVIOUS SAFETY CONSIDERATIONS. I AND MY STRONG OBJECTIONS. IT SEEMED THAT THE CAPT BECAME A 1-MAN CREW AND PROPER CRM STOPPED.
