True … Oh so very true!
True or false:
3 DEU’s are fitted to the aircraft?
False - There are two!
Speed trend vector shows predicted airspeed in how long?
10 Seconds.
When is the Mach speed displayed at the bottom of the speed tape?
Above Mach 0.4
Below this speed it displays Groundspeed.
What happens to flap manoeuvring speed bugs when Flaps 30 or 40 are set?
They are removed.
When is V2+15 (White bug) removed?
At first flap retraction or when VREF is entered into the CDU
Amber no VSPD is displayed on the ground .. Why?
V1 and VR haven’t been selected on the CDU or with the SPD REF selector
Minimum Manoeuvre Speed (Amber) is displayed when?
First flap retraction after Take-off or when a valid VREF is entered. - It provides
1.3g manoeuvre capability to stick shaker below approx 20,000ft
1.3g manoeuvre capability to low speed buffet above 20,000ft
When do the PLI (Pitch limit indicators or “Eyebrows”) display?
When the flaps are not up or slow speed with the flaps up.
If there are disagreements with ILS frequencies or approach courses on the PFD for a certain amount of time they will turn amber and have a horizontal line put through them — What is the period of time?
1 Minute.
At what altitude does the “Rising runway” start to rise?
200’ RA
Radio Altitude is displayed above the Alt tape when?
From 2500’ AGL
The digital display disappears at 1000’ AGL
Box highlighted white for 10 seconds after passing 2500
Round dial appears below 1000’ AGL
Turns amber and flashes for 3 seconds below Rad Alt minimums.
What is different on the vertical speed when V/S pitch mode is engaged?
There will be a Magenta bug for the selected vertical speed.
When is digital vertical speed displayed?
When vertical speed is greater than 400fpm.
AoA DISAGREE indication on PFD’s means what?
AoA values disagree by greater than 10 degrees for more than 10 seconds - Active when the aircraft is above 400’ RA
CDS FAULT (Amber) and CDS MAINT (White) what do they man?
CDS FAULT - A non dispatchable fault displayed prior to the start of the second engine
CDS MAINT - A dispatchable fault displayed prior to the start of the second engine.
“DISPLAYS CONTROL PANAL” means?
Failed EFIS control panel on the affected side.
Can use Both on 1 or Both on 2 to rectify situation by both sides taking the information from the non failed side.
“INSTR SWITCH” means?
Both Captains and First officer’s displays are using the same source of IRU data.
“IAS DISAGREE” means?
Captains and FO’s airspeed indications disagree by more than 5kts for 5 continuous seconds.
“ALT DISAGREE” means?
Captains and FO’s altitude indications disagree by more than 200’ for more than 5 continuous seconds.
True or False:
In PLAN mode, it is depicted MAG north up?
False - It is True North up.
with STA clicked, what range setting will the navaids be displayed?
Up to 40nm, above 40 it will display all high altitude navigational aids.
What orientation are VOR and APP modes presented in?
Heading up
If the ILS frequency and/or course disagree?
They turn amber after one minute and a amber line is drawn through it horizontally.
What appears on the altitude readout above 10,000’?
A green crosshatch
AoA alert is active when the aircraft is?
Above 400’ RA
DISPLY SOURCE means?
DEU 1 or 2 has failed.
What does DISPLAYS CONTROL PANAL indicate?
