Hey again Chuck,
thought about what you have said re the 5 degrees bank. Just plugged the numbers, and I show less than a 0.4% reduction in the vertical lift component with the full 5 degrees bank applied.
Now as you are aware I am not able to calculate the extra performance drag through the 'extra' rudder drag, but it must be some, or any amount equivalent to the loss of said 4 percent. If not, then it would not be in the flight manual. After all performance data is shown in the best light possible!
The bottom line for me is that that it what the flight manual is calculated on, so that is what I shal strive to fly. I am not the greatest pilot ever born, so i shall attempt to stack everything in my favour. As such I shall fly with that 5% on climbout.
Throughout most of these thread there still lies the most important message for the new and not so new twin pilot - read the friggin flight manual and follow it. It is no Harry Potter.
