QRH/ABN-70-A ENG DUAL FAILURE - FUEL REMAINING - DITCHING or Refer to
QRH/ABN-70-B ENG DUAL FAILURE - NO FUEL REMAINING - DITCHING, which has been
amended to include the ditching procedure when the engines are not running.
PREPARATION
ATC/TRANSPONDER........................................................................................NOTIFY/AS RQRD
Notify ATC of the nature of emergency encountered and state intentions.
If not in contact with ATC, select transponder code A7700 or transmit a distress message on:
(VHF) 121.5 MHz or (HF) 2 182 kHz or 8 364 kHz.
CABIN and COCKPIT..................................................................................................... PREPARE
Notify the cabin crew of the nature of the emergency and state intentions.
Specify the available time:
‐ Loose equipment secured
‐ Survival equipment prepared
‐ Belts and shoulder harnesses locked
GPWS SYS............................................................................................................................. OFF
GPWS TERR...........................................................................................................................OFF
Setting the SYS pb and TERR pb to OFF avoids nuisance warnings.
SIGNS........................................................................................................................................ON
GALLEY...................................................................................................................................OFF
LDG ELEV.....................................................................................................................SELECT 00
BARO.......................................................................................................................................SET
Omit normal approach and landing check list.
CREW MASKS/OXY SUPPLY (below FL100)..........................................................................OFF
APPROACH
L/G lever.................................................................................................................................... UP
SLATS and FLAPS....................................................................................................... MAX AVAIL
AT 2 000 FT AGL
CAB PRESS MODE SEL......................................................................................... CHECK AUTO
The outflow valve would remain open, if the MODE SEL pb were not at AUTO.

The outflow valve, emergency ram air inlet, avionics ventilation inlet and extract valves, and pack
flow control valves close.
The ditching direction mainly depends on the wind direction, and on the state of the sea.
These factors may be considered as follows:
1. Wind direction:
This may be determined by observing of the waves, which move and break downwind. Spray
from the 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 the water : 23-35 kt
Spray from the waves : 35-43 kt
3. Sea state:
This is best determined from a height of 500 to 1 000 ft.
At a lower altitude, the swell direction may be less obvious than the wave direction, even
though the waves are much smaller.
4. 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 wind as possible. If drift
exceeds 10 °, ditch into the wind. The presence of drift on touchdown is not dangerous, but
every effort should be made to minimize roll.
Touch down with approximately 11 ° of pitch, and minimum aircraft vertical speed.
