9.50. Spatial Disorientation.

p. 230

9.50.1. Number 1. If suffering from spatial disorientation, immediately tell number 2, and transfer aircraft control to the other pilot if practical. If transfer of aircraft control is not an option, confirm attitude with the other crewmember or number 2. If symptoms persist, terminate the mission, and recover by the simplest and safest means possible.

9.50.2. Number 2. Spatial disorientation is highly likely when flying fingertip in IMC for prolonged periods of time, even during straight and level flight due to the orientation of the number 2 pilots head relative to direction of travel when looking at number 1. If suffering from spatial disorientation, immediately tell number 1, and transfer aircraft control to the other pilot if practical. Number 1 advises number 2 of aircraft attitude, altitude, heading, and airspeed. If symptoms persist and conditions permit, number 1 should establish straight-and-level flight for 30-60 seconds. If possible, number 1 may try to get the formation to VMC conditions. If the condition persists, consider offering the number 1 position. If unable to maintain position and number 2 becomes a threat to number 1, the appropriate lost wingman procedure should be initiated. As number 2, be cautious when initiating lost wingman procedures as this could trigger further spatial disorientation. If necessary, terminate the mission and recover by the simplest and safest means possible.
