ATPL Aero & Systems case studies
ATPL Aero & Systems · Put your knowledge to work in context.
Aircraft General Knowledge - Airframes, Systems and Powerplants is the technical systems paper in the EASA ATPL (Aeroplane) theoretical knowledge set. It is aimed at candidates working toward a commercial pilot licence or ATPL, whether in a modular course or an integrated programme, and it also underpins the type-specific ground school that follows. The ATPL Aero & Systems case studies are 5 cases and about 3,386 words.
1Hydraulic Failure After Take-off on a Twin-Jet
A twin-engine transport has just rotated from a sea-level runway at maximum take-off mass with flaps 5. During gear retraction the flight crew notes the left hydraulic system low-pressure warning, followed by loss of the left gear door indication and slow gear retraction.
741 words, about 4 min2Pressurisation Control Failure at High Altitude
A business jet is cruising at FL410 with a cabin altitude of 8000 ft and a differential pressure of 8.6 psi. The cabin pressure controller is in the automatic mode.
694 words, about 3 min3Asymmetric Thrust and Rudder Authority on a Piston Twin
A light piston twin with counter-rotating propellers is climbing at VY of 105 kt indicated. The left engine fails at 400 ft above ground level shortly after take-off from a 1200 m runway.
687 words, about 3 min4Fuel Imbalance and Transfer Logic in a Multi-Tank Transport
A four-engine transport is in cruise at FL350 with a total fuel of 18 000 kg. The left inboard tank indicates 4200 kg, the left outboard 1800 kg, the right inboard 3900 kg, and the right outboard 2100 kg.
643 words, about 3 min5Hot Brake and Tyre Failure After a Rejected Take-off
A narrow-body jet rejects a take-off at 100 kt on a 2600 m runway. The calculated V1 was 135 kt, so the reject is well below V1.
