Three-system architecture
Green, blue and yellow system questions involving pressure availability and system relationships.
Inside the category
Follow pressure from source to system user
The bank moves between system architecture, component operation and abnormal cases. Grouping questions by pressure source and system colour can make a mixed session easier to review.
Pumps and pressure sources
Engine-driven and electric pump topics, including the controls and conditions represented in the bank.
Power Transfer Unit
PTU availability, control and indication questions across normal and degraded situations.
Emergency supply
RAT and accumulator topics used to test hydraulic availability outside normal supply cases.
Reservoirs, valves and faults
Reservoir pressurisation and quantity, valve states, low-pressure cues and thermal faults.
Users and ground operation
Questions connecting hydraulic availability with aircraft users and ground-service situations.
How to practise
Revise one pressure path, then mix the systems
- Establish the architecture.Use a short Quick to see whether system colours, pressure sources and pumps are already clear.
- Add transfer and emergency cases.Use the builder to keep Hydraulics selected while choosing Quick, Exam or Streak and a suitable length.
- Review missed relationships.After the session, separate source, valve and user errors before returning to your approved course material.
