ATA 31 - Indicating and recording

Question 1

What is an Advisory and when does the “ADV” indication shows

Answer 1

GOAL: indicate to the pilot the presence of a parameter drift in the a/c systems.

The “ADV” sign will show on EWD only if the SD page associated with the parameter drift cannot be displayed at the moment due to several reasons:
1. Another SD is manually selected- adv present on another page.
2. A failure detected by FWC is present at the moment. The SD page is show - but an advisory occurs at the same moment.
3. There is several advisories on several SD pages. The first one’s SD page is dislayed. “ADV” shows in the EWD and SD sw flashed indicating the presence of additional ADVs.

At that moment, the corresponding SD pages associated pushbutton switch will flashes to indicate which system is concerned. The pilot has to fetch the page manually.

Ref. (Fig. Automatic Advisory Mode)
When a parameter drifts out of normal range, the relevant system page is automatically displayed in order to attract crew attention well before reaching the warning level and the corresponding key on the ECAM control panel comes on.
Special means are used to draw crew’s attention to the concerned parameter: the indication (green) and the system page title (white) pulse smoothly as long as there is an exceedance.
Every time one or several parameters of a system exceed a given advisory threshold for a time longer than 2.5s the advisory mode is armed for the corresponding system page.
However, if the value of the parameter exceeds the corresponding alert level, the associated caution or warning is triggered and the indication is displayed in amber or in red.
For each parameter susceptible of an advisory, the advisory mode is inhibited in some flight phases.
However, as long as an A/C system page is on display, the inhibitions for the advisory mode concerning all the parameters presented are not taken into account.

Question 2

What is ISA? Explain what it is.

Answer 2

International Standard Atmosphere (ISA) is in fact a delta ISA indication that appears only in standard barometric reference mode only.

Question 3

Tell me about “LOAD FACTOR” indication and conditions on the SD page

Answer 3

Load factor (G LOAD) is only displayed amber when the value is above 1.4 G or below 0.7 G for more than 2 seconds. The information remains in view for 5 seconds, when the excessive condition has disappeared. The display of the load factor is inhibited during flight phases 1 & 2.

Question 4

What are the conditions that will make the APU and Engines page automatically show on the SD display? (flight phase automatic mode)

Answer 4

For Engine -
Show- Engine start SEQ
Disappear: 10sec after the end of start sequence.

For APU:
Show: APU master SW ON
Disappear: APU master SW OFF or APU RPM > 95% for 10 sec.

In any flight phase, the APU/ENGINE page will be displayed in priority if they are started.

Question 5

What are the flight phase and their associated SD page?

Answer 5

1. Electrical power to 1st engine start (DOOR unless APU or engine start)
2. 1st engine start to 1st engine to T.O power (WHEEL unless APU or engine start)
3. T.O power to CAS > 80 knots (ENG)
4. CAS > 80 knots to LIFT off (ENG)
5. Lift off to 1500ft (ENG)
6. 1500ft to 800ft (CRUISE)
7. 800ft to touch down (WHEEL)
8. Touch down to CAS < 80 knots (WHEELS)
9. CAS < 80 knots to Last Eng Shut Down (WHEELS)
10. Last Eng Shut Down to 5 min after. (DOOR)

Question 6

What do you know about the SDAC?

Question 7

What is ARINC429?

Question 8

EFIS control panel: What does the optional data pushbutton sw do?

CSTR
WPT
VOR.D
NDB
ARPT

Answer 8

CSTR pushbutton switch.
When pressed, the bars come on green, and the constraints related to the waypoints are presented on the ND (only for the TO and for the next waypoints).

WPT pushbutton switch.
When pressed, the bars come on green and all waypoints other than those included in the flight plan are presented on the ND.

VOR-D pushbutton switch.
When pressed, the bars come on green, and all the VOR, DME and VOR/DME ground installation in addition to the tuned Navaids are presented on the ND.

NDB pushbutton switch.
When pressed, the bars come on green, and all the ADF ground installations are presented on the Navigation Display.

ARPT pushbutton switch.
When pressed, the bars come on green, and all the airports in the zone are presented on the Navigation Display.
