Pilot ADS Flashcards
(20 cards)
What does the pitot-static system sense?
Barometric altitude and airspeed
To what aircraft systems does the pitot-static deliver dynamic and static pressure?
The Digital Air Data Unit (DADU) and Integrated Standby Instrument System (ISIS)
How are pitot heater failures displayed in the cockpit?
Via Warnings, Cautions and Advisories (WCA) on the Integrated Display Unit (IDU)
What is a purpose of the Air Data System (ADS)?
To convert air pressures into a digital format
What information is supplied from the Air Data System (ADS)?
Pressure altitude, airspeed, vertical speed, Outside Air Temperature (OAT)
What system components use the analogue Indicated Airspeed (IAS) and height error signals from the Digital Air Data Unit (DADU)?
Computer Acceleration Control (CAC) unit and Automatic Flight Control System (AFCS) computer
[Drag and Drop] Locate the ADU FLT/TEST switch
Panel KJ, right hand side of interseat console below pilots collective lever
What is the purpose of the ADU FLT/TEST switch?
To be used during testing of the Automatic Flight Control System (AFCS)
Under what condition is the test on the Air Data Unit (ADU) flight/test switch prohibited?
In flight only when the Automatic Flight Control System (AFCS) BAR height hold is engaged
Which Primary Flight Display (PFD) indicators are driven by Digital Air Data Unit (DADU) outputs?
Airspeed Indicator (ASI), Barometric Altimeter (BarAlt), Outside Air Temperature (OAT), secondary output to Vertical Speed Indicator (VSI) and wind vector
What is the effect of pressing the “MB↑” and “MB↓” Integrated Display Unit (IDU) bezel keys simultaneously?
The atmospheric pressure is reset to a default value (1013 MB)
When will the wind vector on the Primary Flight Display (PFD) start to indicate?
Above 30 Knots Indicated Airspeed (KIAS)
Between what range can a manual True Airspeed (TAS) be entered into the Control, Display and Navigation Unit (CDNU)?
0-1000 kt
What air data information is shown on the Control, Display and Navigation Unit (CDNU) Nav header?
Range and bearing information, navigation sensor source, ground speed and drift angle, wind velocity data
How is loss of barometric altitude (BARALT) display from the Air Data System (ADS) indicated?
Indicator display moving pointer is removed, a red FAIL replaces the digital readout
How is a large discrepancy between the outputs of the Air Data System (ADS) and Integrated Standby Instrument System (ISIS) indicated?
A CHECK advisory will appear in the affected indicator
What outputs will the Cockpit Display System (CDS) compare to give a CHECK indication if a large discrepancy is detected on the Barometric Altimeter (BarAlt)?
The Digital Air Data Unit (DADU) and the two Integrated Standby Instrument Systems (ISIS)
What initial indication from the Air Data System (ADS) highlights a failure or suspect data feed under normal operating conditions and prior to selection of a reversionary mode?
CHECK caption
How is activation into a reversionary mode on the Airspeed Indicator (ASI) and Barometric Altimeter (BarAlt) indicated on the Air Data System (ADS)?
Depending on the mode selected the “XFR” or “SBY” captions will flash at 1 Hz for 5 seconds and then remain displayed continuously
How is the Air Data System (ADS) recognised on the system status tree view when called up on the TOTE display of the Integrated Display Unit (IDU)?
SCADU
