Supplementary Procedures - PRO-SUP-22 Auto Flight

Question 1

016- When the FM will Automatically Reset Itself?

PRO-SUP-22-10 P1

Answer 1

When the FM Software Cannot Work Properly

Or

The FM Receives Instructions to Perform Impossible Operations.

Question 2

017- What are the possible FM Soft Reset in Case of Erroneous Predictions?

PRO-SUP-22-10 P 10

Answer 2

• Check the CRZ TEMP (Sign and Value),
• Check the Gross Weight and the Cruise Flight Level
• RE-ENTER the Same Cost Index to Restart a Computation

(On DESC or APP, this will NOT Restart a Computation)

• MAKE a COPY ACTIVE, then Activate the Secondary
• MAKE a “DIR TO” to the “TO” waypoint.

Question 3

018- What to do if a Spurious Engine-Out is Detected?

PRO-SUP-22-10 P10

Answer 3

PRESS the EO CLR Prompt of the MCDU PERF Page

RE-ENGAGE Previous Vertical Mode

RE-ENTER Preselected Speeds (If Any).

Question 4

019- What the Meaning of “CHECK GW” Message If the FMS GW on the MCDU is Correct?

PRO-SUP-22-10 P11

Answer 4

It Means the Characteristic Speeds Computed by the FAC

(VLS, F, S, GREEN DOT on PFD) are Not Correct

Use the QRH Operating Speeds (QRH/PER-A Speeds).

Question 5

020- In which Cases the FMGC RESPONSE to a Failure will be:

TOTAL Loss of A/P & A/THR?

PRO-SUP-22-10 P16

Answer 5

• 2 ADC Failure (Air Data Computer)
• 2 FAC Failure (Flight Augmentation Computer)
• 2 IRS Failure (Inertial Reference System)
• 2 LGCIU Failure (Landing Gear Control Interface Unit)
• 2 SFCC Failure (Slat/Flap Control Computer)
• Total Loss of the FCU (Flight Control Unit)

In ALL Cases Above, the Results will be to Fly:

–> RAW DATA.

Question 6

021- In which Cases the FMGC RESPONSE to a Failure will be:

TOTAL Loss of A/THR but A/P OK?

PRO-SUP-22-10 P17

Answer 6

• Loss of One FADEC (Full Authority Digital

Engine Control)

• Loss of EPR (Engine Pressure Ratio).

Question 7

022- What kind of Content is under SUP-22-20 FMGS Specificities?

Answer 7

PRO-SUP-22-20-10 FMS1 Honeywell Specificities

PRO-SUP-22-20-15 FMS2 Honeywell Specificities

PRO-SUP-22-20-18 FMS2 Thales/GE Specificities

PRO-SUP-22-20-20 FG Specificities.

Question 8

023- What defines the Navigation Database Validation to Perform an Approach?

Answer 8

Navigation Database must be Either:

• Produced by a Supplier Compliant with ED76/DO200A

OR

• Validated and Approved by the Operator.
