Cuestionario de Navegación Aérea

1.The Airbus family of single-aisle aircraft includes several types of navigation systems, divided into four main groups:

•  - Air Data Inertial Reference Units (ADIRUS) and

  standby instruments

  - Standby Instruments, 

  - Digital Distance and Radio Magnetic Indicator (DDRMI), 

  - Integrated Standby Instrument System (ISIS). 

•  - Air Data/Inertial Reference System (ADIRS) and

  standby instruments

   - dependent position determining systems

   - landing aids

   - independent position determining systems.

2.There are several subsystems within each group ,The first group includes:

• - Air Data Inertial Reference Units (ADIRUs), 

  - Standby Instruments, 

  - Digital Distance and Radio Magnetic Indicator (DDRMI), 

  - Integrated Standby Instrument System (ISIS). 

• - Air Data/Inertial Reference System (ADIRS)

  and standby instruments

   - dependent position determining systems

   - landing aids

   - independent position determining systems.

The second group (dependent position determining systems) includes:

• - GPS, 

  - ATC/Traffic Alert and Collision Avoidance System

  (TCAS), 

  - DME, 

  - ADF,

   - VOR

• - GWP, 

  - ATC/Traffic Alert and Collision Avoidance System

  (TCAS), 

  - DMI, 

  - ADF,

   - VOR

The third group (landing aids) includes:

•  - ILS,

   - marker receivers.

•  - ILS,

   - ADF,

• - GPS, 

  - ATC/Traffic Alert and Collision Avoidance System

  (TCAS), 

The fourth group (independent position determining systems) includes: 

• - Ground Proximity Warning System (GPWS), 

  - RAs, 

  - Weather Radar (WXR) and Predictive Windshear

  (PWS).

• - Standby Instruments, 

  - Digital Distance and Radio Magnetic Indicator (DDRMI), 

  - Integrated Standby Instrument System (ISIS). 

• - DME, 

  - ADF,

   - VOR

How many ADIRUs does the aircraft have?

•  The aircraft has three identical and interchangeable ADIRUs.

•  The aircraft has three not identical and not interchangeable ADIRUs.

What does each ADIRU do?

• Each ADIRU combines interfaces that carry out one functions in a single unit with a shared power supply

• Each ADIRU combines computers that carry out two functions in a single unit with a shared power supply.

The computers that ADIRU combines are?

•  - Air Data/Inertial Reference System (ADIRS) and

  standby instruments,

   - a strap down Inertial Reference (IR) unit, using laser gyros and accelerometers.

• - An Air Data Reference (ADR) unit,

   - a strap down Inertial Reference (IR) unit, using laser gyros and accelerometers.

The ADR and IR systems of each ADIRU operate independently, and failure of one system does not affect the other one

• TRUE

• FALSE

The ADIRS systems have peripheral components connected to the  LRUs. These components are an integral part of the Air Data  portion. The components are: 

• - pitot probes,

  - static ports,

  - Angle of Attack Sensors (AOA),

  - Total Air Temperature Sensor (TAT). 

• - pitot probes,

  - static ports,- Weather Radar (WXR) and Predictive Windshear

  (PWS).

  - Total Air Temperature Sensor (TAT).
