Applicable to:
ECAM MEMO........................................................................................................................... REVIEW
ECAM SYS PAGES..................................................................................................................REVIEW
Periodically review the system display pages, and monitor ENG oil pressure and temperature, in
particular.
Note: During cruise, oil quantity variation is not linear. A rapid decrease can be noted, especially
at the beginning of the flight.
This is due to an oil temperature decrease that leads to a longer oil transmit time in the
sumps (more oil retained in the sumps).
BLEED : BLEED parameters.
ELEC : Parameters, GEN loads.
HYD : Fluid quantity. After landing gear retraction, the indicated fluid quantity of the green
system is higher than on ground.
COND : Duct temperature, compared with zone temperature.
Avoid large differences for passenger comfort.
FLT CTL : Note any unusual control surface position.
FUEL : Fuel distribution, trim tank quantity, and CG.

Applicable to: ALL
FLIGHT PROGRESS................................................................................................................. CHECK
Note: VLS, shown on the PFD, ensures a 0.3 g buffet margin. Therefore, no additional margin is
necessary in cruise.
Monitor flight progress in the conventional way.
When overflying a waypoint:
Check track and ‐ distance to the next waypoint.
When overflying a waypoint, or every 30 min:
‐ Check fuel: Check FOB (ECAM) , and fuel prediction (FMGC) , and compare with the computer
flight plan or the In-Cruise Quick-Check Table (Refer to PER-CRZ-AEO-ICQ-10 GENERAL)
‐ Check that the sum of the Fuel On Board and the Fuel Used is consistent with the Fuel On Board
at departure. If the sum is either unusually smaller than the Fuel On Board at departure, or if it
decreases, suspect a fuel leak.
CAUTION This check must also be performed each time a FUEL IMBALANCE procedure is
necessary. Perform the check before applying the FUEL IMBALANCE procedure. If a
fuel leak is confirmed, apply the FUEL LEAK procedure.

STEP FLIGHT LEVEL.............................................................................................AS APPROPRIATE

Applicable to: ALL
NAVIGATION ACCURACY........................................................................................................ CHECK
On aircraft equipped with GPS primary, no navigation accuracy check is required, as long as GPS
PRIMARY is available.
Otherwise, navigation accuracy must be monitored, at all times but especially when any of the
following occurs:
‐ IRS only navigation
‐ The PROG page displays LOW accuracy
‐ “NAV ACCUR DOWNGRAD” appears on the MCDU.
If the check is positive (error ≤ 3 nm): FM position is reliable.
‐ Use ND (ARC or NAV) and managed lateral guidance.

If the check is negative (error > 3 nm): FM position is not reliable.
Use raw data ‐ for navigation and monitor it
‐ If there is a significant mismatch between the display and the real position: disengage MANAGED
