Airbus a320 FCOM system auto flight naviagation part2

Question 1
How long it takes for a normal Inertial Reference System (IRS) alignment?

1min
5 min
10 min
20 min
Question 2
How long it takes for a fast Inertial Reference System (IRS) alignment?

30 sec
1 min
5min
10 min
Question 3
To align the IRS, what uses the FMGS ? (e.g: [1R] FROM/TO -> LFOB/LFPG)

The reference point coordinates of the departure airport
The GPS
The last coordiantes of the previous flight
Question 4
During the IRS algnment process after inserted the INIT A the "FROM/TO, it's written "IRS IN ALIGN" memo flashes on the E/WD, which answer is not correct? (on old airbus you can get this info when "ALIGN" flashes on the ADIRS overhead CDU)

It has detected excessive motion (it automatically restarts the alignment)
It has detected a disagreement between the position the MCDU has sent to the IRS, and the last memorized IRS position. The flight crew must enter new coordinates in the MCDU, and realign the IRS
It has detected a disagreement between the latitude, the MCDU has sent to the IRS, and the latitude the IRS has computed during the alignment
The IRS has not received a position from the MCDU
One IRS or two are out of service
Question 5
Can you fly with an outdated navigation database?

Not at all, an updated navigation database is mandatory
In exceptional circumstances, and for a limited period of time, an ACFT can continue to operate beyond the end of the database cycle, provided it is approved by the national authorities
Yes but it's not legal
Question 6
You want to insert a speed constraint on the ACTIVE flight plan, you have to insert it in?

The lateral flight plan revision [using the Left keys]
The vertical flight plan revision [ using the Right keys]
Question 7
When the aircraft overflies a flight plan discontinuity (e.g KORNI - F/PLAN DISCONTINUITY - AGN), the NAV mode will automatically?

Sequences and fly direct TO AGN
Fly direct TO the previous waypoint
Reverts to the HDG (TRK) mode
Fly direct to the departure airport
Question 8
In HDG/TRK mode, a waypoint is sequenced when it passed behind the aircraft, and the aircraft is less than

1 nm from it
5 nm from it
7 nm from it
The Flightplan will not sequence
Question 9
If the aircraft is flying a discontinuity towards a waypoint, this waypoint is sequenced when the aircraft is less than ?

1 nm from it
5 nm from it
7 nm from it
The flightplan will no sequence
Question 10
In term of flight plan capacity, the FMS takes into account ?

Question 11
Each flight plan can contain up to ?

50 legs
100 legs

Question 12
You want to insert on the flight plan a waypoint, you can identify a waypoint by 5 differents way, which answer is not correct?

Its identifier (if it is in the navigation database)
A Latitude/Longitude (LL)
A Place/Bearing/Distance (PBD). The wayoint is defined by its bearing and distance from a place
A Place-Bearing/Place-Bearing (PBX). The waypoint is defined by the interception of 2 radials from 2 places
A Place/Place (PP), The waypoint is defined by equidistant o[...]
A Place/Distance (PD). The waypoint is defined by a distance from a place, along the F-PLAN
Question 13
How many waypoints can be store in the waypoints file database?

5 waypoints
10 waypoints
20 waypoints
50 waypoints
Question 14

Green dot speed
Green dot + 20kt if < 20000ft or green dot + 5kt if > 20000ft
Green dot + 10kt

Green dot speed
Green dot + 20kt if < 20000ft or green dot + 5kt if > 20000ft
Green dot + 10kt
250kt IAS
Question 16
The FMGS offers three types of entry into holding patters, which answer is not correct?

Direct entry
Parallel entry
Opposite entry
Teardrop entry
Question 17
The predicted data for the alternate on the FMS are computed with Cost Index (CI) ?

CI 0
CI 15
CI 35
CI 999
Question 18
The predicted data for the alternate on the FMS are computed with a Gross Weight (GW)?

Aircraft weight being equal to landing weight at the alternate airport
Aircraft weight being equal to landing weight at primary destination
Aircraft weight being equal to landing weight at aiport departure
Always with a GW of 64.5 tons
Question 19
For the predicted data for alternate, if the length between destination and alternate airport is less than 100 nm, calculation take into consideration a flight at

FL 50
FL 100
FL 150
FL 200
Question 20
For the predicted data for alternate, if the length between destination and alternate airport is comprised between 100 nm and 200 nm, calculation take into consideration a flight at

FL 100
FL 150
FL 200
FL 220
