GENERAL FLYING CHARACTERISTICS.(1) GENERAL STABILITY.@) Increasing the power on the inboard enginescauses the airplane to become slightly tail heavy,while a change of power on the outboard engines hasno appreciable effect upon the trim.(Q) Closing the cowl flaps on the inboard enginescauses a similar tail heaviness, but cowl flaps onthe outboard engines have a negligible effect upon thetrim.U;j With the airplane properly trimmed for alanding with power off and flaps down, the pilot mayapply power, throw the flap switch into the up positionand go around with no change in trim tab settingif a second approach is necessary. The flaps retractat a satisfactorily slow rate.(2) TAKE-OFF. - During the take-off run, directionalcontrol should be maintained with ruddermovement and throttles, differential throttling 'beingdone with the outboard engines as much as possible.(3) CLIMB. - The airplane will require very littleelevator trim and the elevator control pressure willbuild up rapidly as the climbing speed is reduced belownormal.(4) LEVEL FLIGHT. - In normal flight, turns canbe made very smoothly with aileron control only. Ininstru~nt flight, the pilot should pay special attention34
