CHAPTER 31 Flashcards
Under normal conditions which displays are driven from DMC 1?
Captains PFD, ND, EWD and SD screens
Where is the slat/flat position indicated?
EWD (upper area)
How is No Computed Data (NCD) displayed on the SD?
No Computed Data (NCD), 3 blues dashes replaces the values (on ground).
How many different ECAM MODES are available?
The ECAM operates in four modes.
1, the normal mode according to the flight phase is automatically presented
2, the failure mode is automatically presented when warning/caution is triggered.
3, the advisory mode is automatically presented when a parameter is
drifting.
4, manual mode, through the ECP.
How are warnings and cautions displayed on the EWD?
The left memo area is dedicated to warnings and cautions (primary or independent failures) or memo information related to procedural pilot actions or memo information.
What causes a secondary failure and where is it displayed?
The right memo area of the EWD is dedicated to the system affected by a warning or a caution (secondary failure).
How many ECAM phases are there in normal mode?
In normal operation the ECAM system pages are displayed according to the current flight phase, this mode is called automatic mode. A flight is divided into 10 phases corresponding to an aircraft configuration change.
What LRU generates the flight phases?
These flight phases are generated by the FWC and used by the Display Units (DUs) to automatically call up the system pages.
ECAM phase 1 in normal mode is?
DOOR
Post flight and engine shut down, how long does it take for the FWC to start a new phase 1?
Five minutes after the last engine shutdown the FWC starts a new flight leg at phase 1.
What determines FWC flight phase 6?
Post lift off and RAD ALT above 1500FT (Cruise)
If the ECAM control panel fails how are the system pages entered?
In the event of an ECAM control panel failure, due to the built in redundancy, the system pages are still available through the ALL key.
What happens if the ALL key is pressed and held?
When the ALL key is pressed and held, all the system pages are displayed successively in one second intervals.
How can you cycle through the system pages manually?
The ALL key, when pressed repeatedly, will enable the display of the next system page.
How many alerts levels are there and which is the highest priority?
The alerts are classified in three levels, level 3 being the highest.
What determines an independent failure?
An independent failure is a failure, which affects an isolated item of equipment or system without affecting another one. Example: Flight Warning Computer (FWC).
How is an independent failure displayed?
An independent failure is displayed with the title underlined.
What happens if a PFD fails?
In the case of PFD failure (detected) or if the PFD unit is switched off by means of its potentiometer, the PFD is automatically displayed on the ND unit.
What happens if the upper display (EWD) fails
In the case of an upper display (EWD) failure or if the upper display control potentiometer is turned to off, the upper display is automatically transferred on the lower display, this mode is called ECAM single display mode.
What happens if the lower DU fails?
If the lower DU fails or if the lower display is turned to off, no automatic reconfiguration is possible, the ECAM works in single display mode. Each crew member also has the possibility to present the SD image on the ND side only, and never on the PFD side, by rotating the ECAM/ND transfer selector switch on the switching panel.
When can a PFR be printed off?
The PFR can only be printed on ground.
How are failures classified?
1, Class 1 failures are the most serious and require an immediate maintenance action subject to the Minimum Equipment List (MEL). 2, Class 2 failures may have consequences if a second failure occurs. A Class 2 failure must be repaired within 10 days.
3, Class 3 failures can be left uncorrected until the next scheduled maintenance check.
