Upset Prevention and Recovery Training (UPRT)
Upsets are not intentional flight maneuvers, except in maneuver-based training; therefore, they are often unexpected. The reaction of
an inexperienced or inadequately trained pilot to an unexpected abnormal flight attitude is usually instinctive rather than intelligent
and deliberate. Such a pilot often reacts with abrupt muscular effort, which is without purpose and even hazardous in turbulent
conditions, at excessive speeds, or at low altitudes.
Without proper upset recovery training on interpretation and airplane control, the pilot can quickly aggravate an abnormal flight
attitude into a potentially fatal LOC-I accident. Consequently, UPRT is intended to focus education and training on the prevention of
upsets, and on recovering from these events if they occur. [Figure 5-1]
Figure 5-1. Maneuvers that better prepare a pilot for understanding unusual attitudes and situations are representative of upset
training.
⦁ Upset prevention refers to pilot actions to avoid a divergence from the desired airplane state.
Awareness and prevention training serve to avoid incidents. Early recognition of an upset scenario
coupled with appropriate preventive action often can mitigate a situation that could otherwise
escalate into an LOC-I accident.
⦁ Recovery refers to pilot actions that return an airplane that is diverging in altitude, airspeed, or
attitude to a desired state from a developing or fully-developed upset. Recovery training serves to
reduce accidents as a result of an unavoidable or inadvertently-encountered upset event. The pilot
can learn to initiate a recovery to a normal flight mode immediately upon recognition of the
developing upset condition. The pilot should ensure that control inputs and power adjustments
applied to counter an upset are in direct proportion to the amount and rates of change of roll, yaw,
and pitch, or airspeed so as to avoid overstressing the airplane unless ground contact is imminent.
