The direction of ditching depends mainly on wind direction and sea state and these factors may
be considered as follows:
1. Wind direction:
This may be determined by observation of the waves, which move and break downwind. Spray
from wave tops is also a reliable indicator.
2. Wind speed:
The following guidelines can be used to evaluate wind speed:
A few white crests : 8-17 kt
Many white crests : 17-26 kt
Streaks of foam along water : 23-35 kt
Spray from waves : 35-43 kt
3. Sea state:
This is best determined from a height of 500 ft to 1 000 ft. At lower height, the direction of the
swell may be less obvious than the direction of the waves, even though the waves are much
smaller.
When there is no swell, align into the wind. In the presence of swell, and provided that drift
does not exceed 10 °, ditch parallel to the swell and as nearly into the wind as possible. If drift
exceeds 10 °, ditch into wind. The presence of drift on touchdown is not dangerous, but every
effort should be made to minimize roll.
Touchdown with approximately 11 ° of pitch and minimum aircraft vertical speed.
