1. G/S MODE:
   A. Inhibits the excessive deviation below glideslope warning “Glideslope”
   B. Used for approaches with glideslope out of service or LDA/LOC approaches.
2. FLAP MODE:
   A. Inhibits the unsafe terrain clearance warnings “TOO LOW FLAPS”
   B. Used in conjunction with a flap malfunction
3. LDG FLAP 3:
   A. Configured the GPWS to expect FLAPS 3 as the final flap setting for landing
   B. Inhibits the “TOO LOW FLAPS” aural warning
   C. Landing memo displays Flap 3 instead of Conf Full

Question 4

Explain manual and automatic operation of the GPWS Terrain feature

Answer 4

1. Manual operation:
   A. A TERR ON ND pb has been selected ON (green)
   B. Terrain is continuously displayed on the respective ND
2. Automatic operation:
   A. Respective TERR ON ND is deselected(light out)
   B. Terrain is automatically displayed on both NDs as a result of a caution or warning
   C. Both TERR ON ND pbs illuminate ON(green)
   D. To remove the terrain display, the pb must reset(lights out)

Question 5

What takes priority, Terrain displays or weather displays?

Answer 5

Terrain

Question 6

What are the Altitude Alerting system indications

Answer 6

It’s designed to alert the pilot of altitude deviations when an Autopilot is NOT engaged by:

1. During a climb or descent, when within 750’ of the FCU altitude
   A. A short duration C CHORD
   B. PFD altitude window border pulses until
   Within 250’ of the FCU altitude.
2. In level flight, if aircraft deviates more than 250’ off of the FCU altitude
   A. Short duration C Chord
   B. PFD altitude window border E pulses

Question 7

What are the details of the Terrain and Weather indications on the NDs?
(Pic)

Answer 7

1. When Terrain is being displayed, TERR (blue) appears in the lower right corner of the ND?
2. When weather radar is on, TILT (blue) with the corresponding tilt angle appears in the lower right corner of the ND

   Both NDs
   D. Amber TERRAIN AHEAD message
   Appears on the NDs
2. Terrain Warning -
   A. Both PULL UP lights (red) illuminate on
   The forward instrument panel
   B. Aural “TERRAIN AHEAD, PULL UP”
   Warning sounds
   C. Terrain displays automatically appear on

Answer 10

1. SBY:
   A. Transponder does not reply
   To interrogations
   B. TCAS functions inhibited
   C. TCAS STBY appears in green in the right
   Column of the E/WD memo section
2. ON:
   A. Transponder replies to ATC radar
   Interrogations.
   B. TCAS functions inhibited
   C. TCAS STBY appears in green in the right
   Column of the E/WD memo section
3. TA:
   A. Transponder replies to ATC radar
   Interrogations
   B. TCAS provides Traffic Advisory (TA)
   Displays on the NDs and aural warnings
   C. TA ONLY appears in white in the lower
   Left corner of the NDs
4. RA/TA:
   A. Transponder replies to ATC radar
   Interrogations
   B. All TCAS capabilities are operational,
   Including:
   1. Both resolution (RAs) and Traffic
   Advisories (TAs) on the NDs
   2. Aural warnings
   3. Preventative and corrective guidance
   Within the PFDs vertical speed
   Indicator

Question 11

What’s the meaning of the number value displayed with the Terrain Display?
(Pic)

Answer 11

1. Appears only when the respective ND is set in the ARC mode
2. Represents the highest elevation of an obstacle that is within the respected NDs setting. Ex. 081 is read as 8100’

Question 12

What’s the function of the TRAFFIC switch on the ATC/TCAS panel?
(Pic)

Answer 12

1. AUTO - Other and Proximate traffic is only displayed if TA or RA intruder aircraft are present
2. ON - Other and Proximate traffic, if present, are continuously displayed

Question 13

What’s the meaning of the indications given for a TCAS Preventive or Corrective advisory?
