If your going to do any radical turns make sure you do them far enough from the pavement so's your drones can stabalize before you begin your final.
I go to 100% zoom in the cockpit to find the strip. After awhiles you wont even need to see the pavement cause you'll know how the airbase lays out when you see the buildings. Then, once Ive done that, I will turn in such a way setting up a final turn which will HO the pavement. Normally Ill use a landmark to aim the bombers during my "setup" maneuver and will use my F3 left/right views to keep an eye on the runway in order to time my final turn correctly.
Now mediums like B-26s, my specialty, you can do far more violent maneuvers in and get away with it. The 26, and one of the things I love about them, you can fly like a fighter. But the heavies you have to be more patient with.
If you have blown an approach, are not being threatened, and have the gas "all 3 you should have", then pull up and maneuver for a new landing approach. I like to stabalize me speed at 200, Alt at 1,500, go to front gun/F3 and use my rudders to setup a new landing approach. Just remember to leave yourself enough room from the runway to line up properly on the strip before dropping flaps for the final descent.
When I was having the same problem as you I went into the TA with 1 bomber and would practice all this, touching down on the runway and then pulling back up to setup a new landing maneuver.
