PRO-NOR-SRP-01-50 CRUISE

Question 1

12- The F-PLN and FUEL PRED pages Display Fuel and Time Predictions throughout the flight. What are they based on?

PRO-NOR-SRP-01-50 P5

Answer 1

They are meaningful if:

• The Lateral and Vertical Flight Plan
• The Winds

Are Kept Accurate Enough as the Flight Progresses.

Question 2

13- When it is Mandatory to Check MIN DEST FOB against DEST EFOB?

PRO-NOR-SRP-01-50 P5

Answer 2

• At the Beginning of the CRZ Phase
• At Any Change of DEST or ALTN Airport

Question 3

14- What happen if the “DEST EFOB BELOW MIN” message is Cleared in CRZ?

PRO-NOR-SRP-01-50 P6

Answer 3

It will Appear Again at the Beginning of the Descent Phase.

Question 4

15- Except for OLD A/C when considering a Step Climb what is the significance of ‘ABOVE MAX’, ‘IGNORED’, ‘STEP AHEAD’ Messages in the ‘DIST/TIME’ Field of the MCDU?

PRO-NOR-SRP-01-50 P11

Answer 4

• ‘ABOVE MAX’ if the Step Altitude Exceeds the MAX ALT
• ‘IGNORED’ if the Start Step Point is < 50 nm from TOD
• ‘STEP NOW’ when the A/C is Within 20 NM of

the Step Point.

Question 5

16- When CRZ FL Mode of the PROG Page will change if the FCU ALT is change?

PRO-NOR-SRP-01-50 P15

Answer 5

If the FCU Selected ALT is Lower Than the Previous CRZ FL

And the A/C is within 200 NM of its Destination:

• The System Activates the Descent Phase (DES)

* Otherwise CRZ FL on the PROG Page changes.

Question 6

17- When the CRZ Targeted Mach will change if the FCU ALT is change? Why?

PRO-NOR-SRP-01-50 P15

Answer 6

• At the Start of the Descent, the Mach Target is

the Managed Mach Number at the Initial CRZ FL

• When the Aircraft Reaches the New Flight Level,

the Mach Target Switches to:

* The Mach number for the lower CRZ FL,

* Or to the speed for the lower CRZ FL if the A/C

Reaches the Crossover Altitude

• This Logic Prevents the Aircraft from Exceeding VMO

during Descent.

Question 7

18- When the Scratchpad Displays “ENTER DEST DATA” on the PERF APPR Page?

PRO-NOR-SRP-01-50 P29

Answer 7

When the PERF APPR Page is Not Completed

And the A/C is Less Than 180 NM From DEST.

Question 8

19- Why VOR/DME shall be Manually Selected when the DEST Have Those NAV AIDS Available?

PRO-NOR-SRP-01-50 P32

Answer 8

When Entering the Identifier in the BRG/DIST of PROG Page this Allows a Permanent NAV Accuracy Check

Best if MSA is Related to It as Well.
