100
Q

What is the target speed in EXP CLB/DES?

A

CLB is Green Dot

DES is 340/0.8M

101
Q

When a mode reversion occurs due to NAV mode disengagement for any reason what should crew do to confirm that?

A 
Crew can confirm within 5s by:
1) FCU Alt change
2) Level Off
3) Selection of V/S
Other wise triple click and FDs will flash
102
Q

Are ALT and speed constraints kept in mode reversion?

A

Speed limit is only kept

103
Q

How will the A/C react if the crew don’t follow FD commands in open climb with AP off?

A

The A/THR will command climb thrust regardless if crew follow FD’s or not.
Automatic Speed Protection will disengage the FD’s at Vmax+4 and A/THR reverts from THR CLB to SPEED

104
Q

What occurs when V/S command is too excessive (CLB and DES)?

A

V/S will the value where Vls in climb or VMAX in descent were reached (V/S boxed in amber on FMA)

105
Q

How will A/C react if the crew don’t follow Open DES FD command with AP off?

A

The A/THR will command Idle thrust so speed will decay until below VLS so the FD will disengage and A/THR reverts to SPEED.

106
Q

Will TCAS mode ever exceed VLS or Vmax?

A

No, the TCAS pitch command will reduce to maintain them if ever reached in RA

107
Q

A

In order not to overshoot the LOC, a geographical pre-capture of the LOC beam is commanded before the LOC is alive (LOC*) the AF uses a 15 degree convergence angle to achieve that

116
Q

Can G/S engage above RA height?

A

Yes but capability will remain CAT 1 until RA is alive

117
Q

What does LAND mode signify? How is it diengaged then?

What is a precaution existing about engaging FINAL APP early?

A

May result in inappropraite speed/altitude management in FINAL APP

129
Q

What does it mean if the FINAL APP TOD arrow is not blue?

A

One engagement condition is not fulfilled

130
Q

What is the definition of a FAF?

A

The position from where the position clearance is defined relative to an Obstacle Clearance Surface. May come at of after FDP

131
Q

What happens if the FINAL APP remains engaged till MAPt?

A

Reversion to HDG V/S

132
Q

When does the FINAL APP disengage?

A

1) Pushin APP or LOC
2) Pulling HDG/TRK
3) Selecting Precision APP
4) Go Around

133
Q

What is a precaution regarding changing the NPA when FINAL APP is engaged?

A

Must press APPR to engage new approach

134
Q

What are the vertical and lateral modes in GA?

A

SRS and GA Track/NAV

135
Q

What are the engagement conditions for GA?

A

TOGA and Config 1 or more

136
Q

What is the speed target in GA SRS? After GA?

A

Vapp or current whichever higher (Limited VLS+25).

After GA its either Gdot or SPEED CSTR

137
Q

What is the A/THR mode without AP/PFD?

A

Speed

138
Q

What are the A/THR arming conditions?

A

1) One FMGC/FAC/FCU channel/LGCIU

2) Two ADIRS and FADECs

139
Q

What is the standard disconnection method for A/THR?

A

1) Instinctive pbs

2) Set levers to IDLE detents

140
Q

When does THR LOCK function come when in normal CLB/MCT detent?

A

1) Pushing the A/THR on FCU

2) A/THR disconnects due to a failure

141
Q

What are three “Temporary Abnormal Behaviors” affecting flight guidance?

A

1) Unexpected G/S mode armed
2) CAT 3 Dual INOP
3) Spurious CAT 2 Dual INOP

142
Q

What may cause the “Unexpected G/S mode armed” abnormal behavior? How to address it?

A

When all APs/FDs and A/THR disconnect simultaneously.

1) On ground: Perform A/C power off
2) Inflight: Recycle APPR button (note: even if performing LOC only approach, recycle is necessary to disarm G/S)

143
Q

What may trigger the “CAT 3 DUAL” with no fails under INOP SYS? How to address it?

A

If an ADR or IR is rejected by FAC or FMGC.

1) Switch APs
2) Reset both FAC pb’s in order

144
Q

The ABM and AN- series may give out spurious “CAT 2 INOP” without any system failures, what may cause it and the respective solution for the issue?

A

May be caused when FMGSs erroneously detect ILS tuning disagreement.

1) Tune 108.0/ 0 degrees on RNAV ILS
2) Check problem disappears
3) Clear the RNAV entry

145
Q

What are the three common A/THR modes?

A

1) THRUST (AP/FD maitain speed)
2) SPEED (AP/FD maintain path)
3) RETARD (Autoland)

146
Q

Describe A/THR RETARD mode?

A

In autoland and LAND mode with AP on, at 40ft A/THR commands IDLE thrust as long as the A/P remains on otherwise reverts to SPEED. The FMA reads RETARD then IDLE

147
Q

What is the flight envelope range in which ALPHA FLOOR is available?

A

From liftoff will 100 RA

148
Q

When does the “A FLOOR” revert to “TOGA LK”?

A

When A/C leaves a-floor conditions

149
Q

What are the speed limits in A/THR speed/mach mode?

A

Selected: VLS and VMax (V/Mmo, VFE, VLE etc)
Managed: Green speeds and VMax (340, VFE, VLE etc)

150
Q

What is the function of APPR A/THR?

A

Below 3200 RA with CONF 1 at least, the A/THR becomes more responsive to speed variations

151
Q

When is G/S mini active and what are its inputs?

A

Active when: Speed is managed and APPR phase active

Inputs: Tower HW/ Current HW and VAPP

152
Q

How is the VAPP calculated in GS Mini?

A

VLS + 1/3 Tower HW or VLS+5 whichever is greater

Max +15kts

153
Q

How is the VAPP managed speed target computed?

A

VAPP + (Current HW- TWR HW)

154
Q

On/during descent, the VERT DEV is considered reliable as long as the crosstrack is less than what?

A

The flight crew can use the VERT DEV to monitor the descent provided that the crosstrack error is less than 5 NM.

155
Q

What are the parameters foe Waypoint sequencing?

A

The waypoint is behind the aircraft

The XTK between the FMS lateral flight plan and the aircraft is less than 7 NM

The angle between the current aircraft track and the FMS desired track is less than 90 °.
