Indicating/Recording Systems Flashcards
What is the effect of “Both FWC fault” on the ECAM Warning and caution indications?
ECAM warnings, cautions, status. Altimeter alert and altitude call outs not available. Pilots must refer to overhead panel lights to identify faults.
After a single DMC failure, how would a crew member recover the lost display unit?
EIS DMC switch to CAPT3/FO3
What do you see in each case of DMC failure?
DMC1 - “Invalid Data” on CAP PFD/ND. DMC2 drives ECAM
DMC2 - “Invalid Data” on FO PFD/ND.
DMC 3 - loss of standby DMC.
All would show ECAM caution
What should you do if both ECAM screens fail?
Use “ECAM/ND XFR” to display EWD on ND. Push and hold relevant systems buttons to display on ND (max 3 min)
What happens if CAPT left screen fails?
PFD automatically transfers to ND. Nd can be displayed using PFD/ND XFR switch.
Define an advisory, level 1 caution, level 2 caution, and warning. What indications trigger in each case?
Advisory - systems parameters monitoring. Relevant page is shown on the SD and the parameter pulses green. With single ECAM “ADV” appears on screen.
Level 1 caution - failure leading to a loss of redundancy or system degradation. No chime. ECAM caution listed but no procedure shown.
Level 2 caution - system failure without direct consequence on flight safety. Single chime, steady master caution, and relevant system page.
Level 3 - aircraft is in a dangerous configuration or the failure impacts flight safety. Continuous chime, master warning, systems page and red note on EWD.
If only 1 ECAM operative, how is an advisory brought to crew attention?
ADV appears on upper part of EWD and the associated pb on the ECAM control panel flashes to identify the appropriate system page.
What is meant by independent, primary and secondary failures?
Independent - a failure that affects an isolated system or item of equipment without degrading the performance of others in the aircraft
Primary - a failure of a system or item of equipment that costs the aircraft the use of other systems or items of equipment. Usually shown BOXED.
Secondary - the loss of a system or an item of equipment resulting from a primary failure. Usually shown with a *
What is the purpose of the TO and LAND INHIBIT memos? In what phases of flight are they disabled?
Inhibit some ECAM messages to avoid crew distraction in critical phases of flight.
T/O INHIBIT - Phases 3,4,5
LAND INHIBIT - Phases 7 & 8
When do the TO and LDG memos appear on the EWD?
TO- 2 mins after second engine start or when the TO config button is pressed, until TO thrust is set.
LDG - below 2000ft until touchdown and 80kts
When is the STS SD called up automatically?
When the page is not empty and F/C clear it on EWD or select CONF1 for approach.
What is the effect of pressing the RCL button on the ECAM control panel?
Less than 3 seconds - displays all alerts previously cleared that are still active.
More than 3 seconds - displays all alerts still active and all previously cancelled by the emergency cancel button.
When should the EMER CANC button be used? What effect does this have on warnings and cautions?
Only.used to supress spurious master cautions.
Cautions - cancels any present cautions for the rest of the flight.
Warning - cancels the aural warning and extinguishes the warning light. It does not affect the ECAM - warnings will still appear there!
What is the effect of pressing the TO config button?
Simulates the application of TO thrust.
How does the ALL button work on ECP?
Cycles through all pages at 3 second intervals. To stop at a page. Release the pb.
