? Loss of AP
? Flight control law degradation (F/CTL PROT)
? Landing in abnormal configuration
? Extensive ECAM procedures with associated workload and task-sharing considerations
? Significant considerations for approach, landing and go-around.
GENERAL GUIDELINES
It is important to note that the AP will not be available to the crew but both FD and A/THR still
remain. Additionally, depending on the affected hydraulic circuits, aircraft handling characteristics may be different due to the loss of some control surfaces. The PF will maneuver with care to avoid high hydraulic demand on the remaining system.
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
ABNORMAL OPERATIONS
HYDRAULIC
? Braking and steering considerations
? Go around call out, aircraft configuration and speed
