Need to Know Flashcards
What does erroneous or unusual altitude and or airspeed indicate, when parked at the gate?
Blocked static ports
Note: Do not pushback from the gate until all static ports are verified to be free of ice (or other blockage) and all altitude and airspeed indications are normal.
What four items should be considered when communicating with the Flight Attendants about turbulence?
Provide advanced warning if possible
The effects of turbulence vary throughout the cabin
Ensure the Flight Attendants are seated
Take immediate action and contact Flight Attendants when encountering unexpected turbulence
What resources are used to communicate ride conditions with Flight Attendants?
A thorough briefing
WSI app for a visual aid
What helps to reduce risk to both passengers and Flight Attendants during turbulence?
Turn on the FASTEN SEATBELT sign and a make a PA.
Which Engine Failure Procedures (EFP) are provided on the TLR?
- Standard EFP
- A Simple-Special EFP
Note: This information is also displayed in the ACARS PWB Takeoff data. Simple Special data may also be found on the appropriate Jeppesen -7 pages.
Where is Complex-Special EFP information located, when applicable?
Due to length, Complex-Special EFPs are only depicted on Jeppesen -7 pages with a text and graphic description.
When at the gate, if verbally advised by the Operations Agent of a new Weight and Balance Report number due to additional Passengers, baggage, or cargo, what is your course of action?
- Remain at the gate with the parking brake set and the Passenger boarding door open until the Weight and Balance Report number is received and confirmed by the Operations Agent.
- Complete the AOM 6.8 PWB Takeoff Data Review procedures.
- Complete (or rerun if already completed) the Before Push Checklist.
If a non-standard climb gradient is entered on the Takeoff Conditions page, does the PWB Takeoff Data Uplink load the required Climb power option (e.g., CLB or CLB-1) on the N1 LIMIT page?
No, they do not auto-populate. Manually select the climb thrust setting specified on the PWB runway-specific TAKEOFF DATA page (i.e., CLB or CLB-1) if the FMC calculated climb thrust setting does not meet or exceed the requirement. This ensures takeoff performance will meet or exceed the required climb gradient.
When entering a SID, non-standard climb gradient under takeoff conditions, what climb gradient is entered?
The first climb gradient above 1000 ft. AAE.
Which value is used to set the stab trim? The PWB or FMC TAKEOFF REF ½ Page setting?
The stab trim is set to the PWB setting.
When is the white MAINT light displayed and what does it indicate?
While on the ground, this MAINT prompt is always displayed on the SYS page. This prompt allows entry into the Onboard Maintenance Function (OMF) menu.
The amber MAINT light is displayed, what does it indicate?
This MAINT light illuminates when a system fault is detected.
If the amber MAINT caution light is illuminated, what action must you take?
A system fault exists that much be reviewed by Maintenance. Contact Dispatch / Maintenance Control.
When is the amber MAINT light inhibited?
This light is inhibited from first engine start until 30 seconds after landing.
How does the rollback of the LEAP 1B differ from the CFM-56?
The LEAP 1B may have multiple small EGT rollbacks during start.
When do you call “ROLLBACK” on the LEAP 1B?
Only when the EGT redline indication disappears.
What could happen if you reconfigure the pressurization panel prior to ROLLBACK?
A start malfunction and an aborted engine start.
How is the LEAP 1B engine affected when not adhering to the three minute stabilization and warm-up limitations?
Over time it results in reduced efficiency (increased fuel burn) of the engine.
During taxi, Dispatch notifies you of an error/ omission in the current Weight and Balance Report. Can you depart with a simple acknowledgement and no further action?
No, you must request new TO DATA and review / upload the new data and complete the Departure Plan Checklist.
When is the Departure Plan Checklist required?
When changes are made to FMC programming or PWB data after pushback has commenced.
What does the Departure Plan Checklist capture that is not covered by re-accomplishing the Before Push Checklist?
FMC Programming and briefing items
What is the engine stabilization requirement prior to takeoff for the LEAP engine?
Operate at or near idle thrust, after rollback, for a minimum of three minutes prior to applying takeoff thrust.
What percentage N1 are thrust levers momentarily advanced to before applying takeoff thrust?
Approximately 40%
Note: This is to verify and monitor symmetrical spool up to takeoff thrust and ensure directional control in maintaining runway centerline.
What are some conditions that may increase the risk of a tail strike on takeoff?
Excessive Rotation Rate
Rotation at Improper Speed
Entering wrong weights, incorrect CG and setting the incorrect trim units
Does the takeoff procedure change if you are on a narrow runway?
Yes. Takeoff on a narrow runway requires lining up on the runway centerline and a static run-up to at least 40% N1 before releasing brakes and applying takeoff thrust.
What is considered a narrow runway?
For a B-737, narrow runways are defined as runway widths measuring less than 45 m (147.6 ft) down to and including 30 m (98.4 ft).
If an engine exceedance occurs after thrust is set and the decision is made to continue the takeoff, what is the minimum altitude required before accomplishing the Engine Limit Checklist on the Quick Reference Card?
400ft AGL
Why is there a requirement to monitor flap and slat retraction?
To ensure proper retraction of both the flaps and slats as well as prevent flap overspeed conditions.
What are the Turbulent Air Penetration Speeds?
250 kt at or below 15,000 ft
280 kt / .76 Mach above 15,000 ft
Can you initiate a CRZ DES with the use of the ALT INTV button?
Yes, select a lower MCP altitude AT or ABOVE any descent constraint altitudes and further than 50 NM from the current TOD.
You’ve initiated a CRZ DEC with the use of the ALT INTV button. Do you need to set the new altitude into the FMC?
No. Selecting ALT INTV under these conditions causes the VNAV to function like the CRZ DES function. The FMC CRZ page is automatically loaded with the MCP altitude.
When using ALT INTV within 50 NM of TOD, VNAV transitions to what mode?
Early Descent mode
You receive clearance to continue to a lower altitude while in a CRZ DES mode and then set that altitude into the MCP; does VNAV continue descending to the lower altitude?
No, VNAV remains in CRZ DES mode; it levels off at the previously programmed cruise altitude.
You receive clearance to continue to a lower altitude while in a CRZ DES mode and then set that altitude into the MCP. Using the FMC and ATC clearance, what steps are taken to continue the descent?
- First go to the ACT CRZ DES page and select PLANNED DES
- Then select DES NOW and EXEC Cruise Descent logic is removed, setting up an Early Descent Logic.
