I've got a question for any SIX pilots around here...
What was the initial rate of climb for the F-106? I ask because I have several books on the SIX that show the rate anywhere from 29,000 fpm to 41,000 fpm.
The only thing I have noticed is that the US published books tend towards lower performance numbers whereas the UK published books tend towards the upper numbers.
So what were the performance specs? Oh yeah, if anyone is interested, I can list the books and page numbers that quote performance specs.
Thanks, Lee Stanford

Dear Lee, I am NOT a pilot, but the MA-1 Tech on the 106 for 20 years. The differences you read are due to different authors and how they read the climb charts, if they have them. The numbers are too variable. Below is quoted from T. O. 1-F106A-1-1, Section III "CLIMB" CLIMB Figures 3-1 through 3-4 present the subsonic performance of the clean airplane using maximum thrust respectively. Figure 3-5 shows F-106A climb performance for the gun configuration with two 360-gallon external tanks. Figure 3-5A through 3-8 show climb performance with 360-gallon tanks installed. These charts show time to climb and distance to climb as a function of gross weight. Gross weight-guide lines represent the weight reduction as fuel is used in the climb. The recommended climb schedule is shown in table form on each chart. This climb schedule allows a constant altitude acceleration from takeoff to 400 KCAS; climb at 400 KCAS until reaching the 0.92 Mach number; then climb to altitude at a constant 0.92 Mach number. NOTE The acceleration from takeoff to 400 KCAS may be a climbing acceleration for terrain clearance. For good acceleration characteristics, the airplane should not exceed 15 degrees with maximum thrust and 10 degrees with military thrust after accelerating in level flight to a speed at which the airplane attitude may be sustained without sinking. e-mail me and I will send you the charts, but unless you have a flyable machine, they will not tell you much. There are too many variables. You do know that you can drain the tanks in about 15 minutes at max power, so fuel management is a must. Happy Flying, Jack

Dear Lee, The numbers are too variable. Below is quoted from T. O. 1-F106A-1-1, Section III "CLIMB" (content edited to save space) Happy Flying, Jack Jack, Thanks for the reply. Based on what you tell me, I can begin to see why the numbers vary so much in the books. I am a (student) private pilot so it would be interesting to see the charts. I'll email you. Thanks again, Lee Stanford

Rate of climb= the amount of airspeed, divided by the distance remaining to the vertical object at the end of the runway , multiplied by the height of said object plus 50' safety factor....... Remember standing on the ramp at Chanute on a Sunday PM watching this dude in a bright orange flt suit climb into an F-104, fire up, taxi out, roll down the runway about 800' rotate and point the nose vertical and climb out of sight- straight up......All I could say was holy $hit!!!!!!!The F-86 pilot standing next to me said, yep, 5g take off, blackout to 20,000 level off at 30,000, start descent into Bunker Hill AFB and barely have enough fuel to taxi to the ramp.........Rate of climb=a third useless item of flight that goes along with the runway behind you and the altitude above you.......... Rate of climb= angle of attack that allows you to increase altitude and maintain or increase airspeed.........If utilizing max allowable rate of climb is important in flying, then SINK rate is even more important......Perhaps today it is called glide ratio,or altitude vs distance to runway...........Like Black Bart says, fantastic rates of climb are always achieved by sacrificing at least one desireable flt feature.......If the stick shakes in your hand or the rudder pedals vibrate your feet, you have crossed over into the area of the STALL, or definite lack of rate of climb...........Just ribbin ye Lee........But it was always a great thrill to watch a SIX roll a few hundred feet, light the burner and go like hell skyward .....Most takeoffs, the burner was lit, brakes released- but was lightin the burner as it was rollin was the most impressive.......Miss the sound and feel of that J-75.......The Old Sarge
