022 14 01 00 Cockpit voice recorder (CVR)
022 14 01 01 Purpose, components, parameters
(01) Describe the purpose of a CVR, its typical location, and explain the implications of knowingly erasing or tampering with any information or equipment.
(02) “List the main components of a CVR:
— a shock-resistant tape recorder or digital storage associated with an underwater locating beacon (ULB);
— a cockpit area microphone (CAM);
— a control unit with the following controls: auto/on, test and erase, and a headset jack;
— limited flight-deck controls such as erase and test switches.”
023 “List the following main parameters recorded on the CVR:
— voice communications transmitted from or received on the flight deck;
— the aural environment of the flight deck;”
Syllabus reference BK Syllabus details and associated Learning Objectives
“— voice communication of flight crew members using the aeroplane’s interphone system;
— voice or audio signals introduced into a headset or speaker;
— voice communication of flight crew members using the public address system, if installed.”
022 14 02 00 Flight data recorder (FDR)
022 14 02 01 Purpose, components, parameters
(02) Describe the purpose of an FDR and its typical location.
(02) “List the main components of an FDR:
— a shock-resistant data recorder associated with a ULB;
— a data interface and acquisition unit;
— a recording system (digital flight data recorder);
— two control units (start sequence, event mark setting);
— limited flight-deck controls, but includes an event switch.”
(02) “List the following main parameters recorded on the FDR:
— time or relative time count;
— attitude (pitch and roll);
— airspeed;
— pressure altitude;
— heading;
— normal acceleration;”
Syllabus reference BK Syllabus details and associated Learning Objectives
“— propulsive/thrust power on each engine and flight- deck thrust/power lever position, if applicable;
— flaps/slats configuration or flight-deck selection;
— ground spoilers or speed brake selection.”
(02) State that additional parameters can be recorded according to FDR capacity and applicable operational requirements.
022 14 03 00 Maintenance and monitoring systems
022 14 03 01 Helicopter operations monitoring program (HOMP): design, operation, performance
(01) Describe the HOMP as a helicopter version of the aeroplane flight data monitoring (FDM) program.
(02) “State that the HOMP software consists of three integrated modules:
— flight data events (FDEs);
— flight data measurements (FDMs);
— flight data traces (FDTs).”
(03) Describe and explain the information flow of an HOMP.
(04) Describe HOMP operation and management processes.
022 14 03 02 Integrated health and usage monitoring system (IHUMS): design, operation, performance
(01) “Describe the main features of an IHUMS:
— rotor system health;
— cockpit voice recorder (CVR)/flight data recorder”
Syllabus reference BK Syllabus details and associated Learning Objectives
“(FDR);
— gearbox system health;
— engine health;
— exceedance monitoring;
— usage monitoring;
— transparent operation;
— ground station features;
— monitoring;
— rotor track and balance;
— engine performance trending;
— quality controlled to level 2.”
(02) Describe the ground station features of an IHUMS.
(03) “Summarise the benefits of an IHUMS including:
— reduced risk of catastrophic failure of rotor or gearbox;
— improved rotor track and balance giving lower vibration levels;
— accurate recording of flight exceedances;
— CVR/FDR allows accurate accident/incident investigation and HOMP;
— maintenance cost savings.”
(04) State the benefits of an IHUMS and an HOMP.
022 14 03 03 Aeroplane condition monitoring system (ACMS): general, design, operation
(01) State the purpose of an ACMS.
Syllabus reference BK Syllabus details and associated Learning Objectives
(02) “Describe the structure of an ACMS including:
— inputs: aircraft systems (such as air conditioning, autoflight, flight controls, fuel, landing gear, navigation, pneumatic, APU, engine), MCDU;
— data management unit;
— recording unit: digital recorder;
— outputs: printer, ACARS or ATSU.”
(03) State that maintenance messages sent by an ACMS can be transmitted without crew notification.
(05) Explain that data from the ACMS can be used as part of an FDM and safety programme.
(05) Explain that the FDM program collects data anonymously; however, grave exceedance of parameters may warrant a further investigation of the event by the operator.
(06) Explain the purpose of FDM as a system for identifying adverse safety trends and tailoring training programmes in order to enhance the overall safety of the operation.
