The PF will be very busy flying the aircraft and handling the communications with the flight controls
in Alternate Law.
A double hydraulic failure is an emergency situation, with red LAND ASAP displayed, and a
MAYDAY should be declared to ATC. A landing must be carried out as soon as possible bearing in
mind, however, that the ECAM actions should be completed prior the approach.
PF will then require the ECAM actions. A clear reading of STATUS is essential to assess the
aircraft status and properly sequence actions during the approach.
This failure is called a "complex procedure" and the QRH summary should be referred to upon
completion of the ECAM procedure Refer to OP-040 USE OF SUMMARIES.
While there is no need to remember the following details, an understanding of the structure of the
hydraulic and flight control systems would be an advantage. The F/CTL SD page and the Ops
Data section of the QRH provide an overview of the flight controls affected by the loss of hydraulic
systems.
The briefing will concentrate on safety issues since this will be a hand flown approach with certain
handling restrictions:
• Use of the selected speeds on the FCU.
• Landing gear gravity extension
• Approach configuration and flap lever position

• Approach speed VAPP
• A stabilized approach will be preferred
• Tail strike awareness
• Braking and steering considerations
• Go around call out, aircraft configuration and speed

This situation might occur following completion of a L/G GEAR NOT DOWNLOCKED procedure. It is
always better to land with any available gear rather than carry out a landing without any gear.
In all cases, weight should be reduced as much as possible to provide the slowest possible
touchdown speed. Although foaming of the runway is not a requirement, full advantage should be
taken of any ATC offer to do so.
