Instruments Flashcards
The FD command bars flash for ten seconds and then remain on steady when:
First AP or FD engagement;or
Reversion to HDG/VS mode, whether automatic reversion or manual; or
Change of selected flight level when ALT* (capture) mode is engaged; or
Loss of LOC or GS in Land mode or loss of Land mode.
Managed Guidance is described as:
The aircraft is guided along the preplanned route, vertical, lateral, and speed/Mach profile.
Predicted targets are computed by the FMGS.
Selected guidance can be described as:
The aircraft is guided to the selected target, modified by the pilot.
Targets are selected on the flight control unit located on the pilot’s glareshield.
The Managed Guidance symbol colour is:
Magenta
The selected guidance symbol colour is:
Blue
If the Managed target speed is associated with the ECON speed range:
A magenta double bar is the target
The speed trend arrow disappears when:
Less than 1 knot or if the FAC’s are inoperative.
The VR speed is not displayed until:
Within the speed range of its value.
The symbol that will appear for VR is:
A small blue circle.
The V1 and VR speeds will blank:
After lift off.
During take off V2 will appear as a:
A magenta coloured triangle.
For a Normal take off the FD pitch command for SRS will be to:
Maintain at least V2+10, however will also limit the pitch to +18* causing the aircraft to accelerate to a speed greater than V2+10.
An active windshear warning will allow the SRS guidance to increase pitch to:
+22.5*
A green s on the speed tape during take off indicates the:
Minimum speed for slat and flap retraction to provide stall margin protection for Config 0.
VFE for Config full is:
177kts
VFE for Config 3 is:
185kts
VFE for Config 2 is:
200kts
VFE for Config 1 is:
230kts
F is the minimum speed for:
Flap retraction at the current gross weight.
VMO is:
350kts
MMO is:
0.82
If the target speed is off scale it will be displayed:
In digital format
The Mach value only appears if the Mach is above:
0.5
A green speed protection symbol indicates:
The speed at which overspeed protection becomes active.
The overspeed protection activation speed is:
VMO +6, or MMO +0.01.
Minimum selectable speed (VLS) is the top of:
The amber strip.
VLS information is inhibited:
From touchdown and 10 seconds after lift off.
The Alpha Protection Speed (VaPROT) is at the:
Top of the black and amber strip on the speed tape.
The Alpha Protection Speed (VaPROT) corresponds to the angle of attack:
At which Alpha protection becomes active in Normal Law. Displayed in pitch Normal Law.
V-Alpha Max speed (VaMAX)is the top of the:
Solid red strip on speed tape.
VaMAX represents the speed corresponding to the maximum angle of attack that the aircraft can attain in:
Pitch Normal Law. Displayed only in Pitch Normal Law.
If in Pitch Alternate or Pitch Direct Law the VLS is available along with:
The Stall Warning Speed (VSW). VSW is the top of a red and black strip. It is the speed corresponding to the Stall Warning.
Best Lift Over Drag Speed (L/D) displays as:
A small green circle when in a clean configuration.
L/D is also the:
Maximum Endurance and Engine Out operating speed in a clean configuration.
The upper margin of the speed range (managed) will decrease to —— if a speed limit or constraint is active.
+5kts
The upper margin of the speed range (managed) is limited to the lowest speed of:
VMAX, VMO -3kts, or MMO -0.06.
The lowest margin of the speed range (managed) is limited to the highest speed of:
Green dot, S, F, or VLS.
Below 15000ft a ——- ——- bar symbol will appear on the speed tape at the maximum speed for the next further extended flap position (VFE NEXT).
Double amber bar.
