Navigation Flashcards
There are 2 GPS antenna integrated in
2 MMR
The acquisition mode of the GPS needs at least
4 satellites signal to switch to nav mode
The ALT AID mode of the GPS is when signal is lost and only 3 satellites are used, after 2 minutes, the MMR goes back to
The acquisition mode
The A/C is equipped with what navaid
2 VOR, ILS, DME, ADF and 1 marker beacon
How do you get the navaid autotune back
By clearing the manually tuned navaid
PWS is active below
2300 feet AGL
PWS does not give advisories at
Above 1500 feet AGL or between 0 and 50 feet AGL
The range of TCAS is
100 NM and +/- 9900 feet
What is the appropriate speed to respond to an RA
Manoeuver in less than 5 secs, and with about a 0.25g pull or push
Of there is a reversal or increase of an RA, the response should be executed in
Less than 2.5 secs and with about a 0.35g manoeuver
TA is temporarly and auto selected when
Stall, windshear or GPWS
All RA are converted to TA when
In climb, below 1100 feet or in descent, below 900 feet AGL
The TCF only uses which FMS
FMS 1 and do not revert to FMS 2
Terrain alerts are auto inhibited when
A windshear warning is delivered
What are the 3 functions of the FG part of the FMGEC
FD, AP and A/THR
Selected guidance has
Priority over managed guidance
How many FMGEC makes the FMGES
2 FMGEC
How many MCDU are in the A/C
3 MCDU
On the MCDU, blue is used for
Modifiable and selectable data
On the MCDU, green is used for
Non-modifiable data and active data
On the MCDU, magenta is used for
Contraints and max altitude
On the MCDU, yellow is used for
The alternate flight plan
INIT B page is not accessible when
The first engine starts
Does the trip wind function calculation includes the alternate
No
The FMGEC takes the 3 IRS and come up with
A Mix IRS position
What is called the combined position of the IRS and GPS
GPIRS
If all 3 GPIRS position are not accurate enough, what is then used to update the position of the IRS
The radio nav
All position are referenced on
The MIX IRS position
How do you get an indication the nav accuracy has changed
By a message in the scratchpad and an indication on the ND
If the parameter for GPS PRIMARY are not met, what happens
The field is blank
A GPS PRIMARY LOST message will be posted on
The scratchpad and an indication on the ND
The temporary flight plan will be shown in what color
Yellow
For a hold, is the speed or altitude a priority
The speed (the A/C will decelerate even if it loose the vertical path)
How it the feul calculated in holding pattern
Computes fuel at each wypoint passage for 1 more turn
Does the back-up nav function of the MCDU has a database
No, you can only input LAT/LONG info
Does the FMGEC interpolate or extrapolates the winds
Yes
The back-up nav function of the MCDU is automatic
No
