SOP's Flashcards
What audio test signals will you expect to hear for the CVR that is able to record for 120
min?
For CVR 120 min:
‐ A short tone, or
‐ A short tone and a beep every 4 s, or
‐ Two short tones and a beep every 4 s.
When will the crew select the PACK flow to the HI position?
And the LO position?
LO : If the number of occupants is below 141.
HI : For abnormally hot and humid conditions.
NORM : For all other normal operating cases.
If the APU is supplying, pack controllers select HI flow automatically, independent of the selector
position.
During the Cockpit Preparation ELEC BAT Check, what actions will the crew is going to do
if the charge of at least one battery is not below 60A?
If the charge of at least one battery is not below 60 A:
Wait until the end of the charging cycle of the batteries and perform this check again.
In which situations will you perform a complete IRS alignment?
A complete IRS alignment must be performed in the following cases:
‐ Before the first flight of the day, or
‐ When there is a crew change, or
‐ When the departure airport is located between latitudes 2 ° north and 2 ° south, or
‐ When the GPS is not available and the NAVAID coverage is poor on the expected route, or
‐ When the GPS is not available and the expected flight time is more than 3 h.
In which situations will you perform a fast IRS alignment?
A fast IRS alignment must be performed if a complete IRS alignment is not necessary and the difference between the IRS position and the FMGC position is at or above 5 NM (see MCDU POSITION MONITOR page).
What are the conditions required to perform ADIRS alignment?
To perform an alignment, the aircraft must be stopped on ground. Do not align IRS during engine start, or while the engines are running. In the case of aircraft movement during the IRS alignment, the flight crew must perform a new full alignment.
Why is it important to select the PA reception knob on ACP 3 during the Cockpit
Preparation?
This allows cabin attendant announcements to be recorded on the CVR.
Why are OEBs issued?
An Operations Engineering Bulletin is published to inform Operators of any deviations from initial design objectives that have a significant operational impact. An OEB provides the Operators
with technical information and temporary operational procedures that take into account these deviations.
An OEB:
‐ Is temporary and usually focuses on one operational subject only
‐ Is included in the OEB section of the QRH so that the flight crew can easily access it
‐ At any time during the flight, if the OEB conditions are applicable, the flight crew must apply the
operational procedure(s) that is in the QRH OEB section.
Meaning of white and red OEB’s?
Red: RED OEBs are published to indicate that non-compliance with the recommended procedures may have a significant impact on the safe operation of the aircraft. The Operators shall provide all flight crews with these OEBs or their content without delay.
White: WHITE OEBs are published to indicate that non-compliance with the recommended procedures may have a significant impact on aircraft operation. Airbus recommends that the Operators apply these OEBs within 30 days from the date of publication of these OEBs.
