Line 12:

Additionally, asymmetrical thrust has been used for directional control: if the left engine is idled and power is increased on the right side this will result in a [[yaw angle|yaw]] to the left, and vice versa. If [[Aircraft engine controls|throttle]] settings allow the throttles to be shifted without affecting the total amount of power, then yaw control can be combined with pitch control. If the aircraft is yawing, then the wing on the outside of this yaw movement will go faster than the inner wing. This creates higher lift on the faster wing, resulting in a rolling movement, which helps to make a turn.

Controlling [[airspeed]] speed has been shown to be very difficult with engine control only, often resulting in a fast landing. A faster than normal landing also results when the [[High-lift device|flaps]] can not be extended due to loss of hydraulics.

Another challenge for pilots who were forced to fly an aircraft without functioning control surfaces was to avoid the [[phugoid]] instability mode (a cycle in which the aircraft repeatedly climbs and then dives), which required careful use of the throttle.
