Bulletins

Question 1

What should the flight crew do after engine start?

Answer 1

Check the generator OFF lights on the electrical panel are not illuminated.

Question 2

When can fuel flow indication blank?

Answer 2

During descent, with thrust at or near idle.

Question 3

What actions should be done when uncommanded turns occur in LNAV?

Answer 3

Select HDG SEL and then perform a DIRECT TO and reengage LNAV.

Question 4

What should be done if FUEL IMBALANCE EICAS message occurs in flight?

Answer 4

Check fuel quantity readings to determine if the fuel quantity is fluctuating, or if a true imbalance or fuel leak exists. If the fuel quantity fluctuates or suddenly increases or decreases and remains at a low level, and an imbalance or fuel leak is not suspected, consider the indications erroneous.

Question 5

When can a smoke alarm annunciation be considered nuisance?

Answer 5

If no smoke source is present and the alarm occurred immediately after a power transfer, consider the alarm a nuisance occurrence.

Question 6

What should be done with the EICAS message SMOKE BBAND UPR DR2?

Answer 6

Nothing, this is a nuisance message.

Question 7

What should be done when required to cruise at an altitude below optimum?

Answer 7

Set the STEP (L4) size to zero on the ACT ECON CRZ page. This ensures best available FMC FUEL and ETA predictions.

Question 8

The PASSENGER ADDRESS EICAS status message shows before dispatch, what must be done?

Answer 8

Instruct the cabin crew to make sure all cabin speakers are working. If all cabin speakers are working, the PASSENGER ADDRESS status message may be considered a nuisance and dispatch is allowed.

Question 9

Will the FMC allow the crew to enter two different waypoints with the same identifier?

Answer 9

No, the crew will have to enter the LAT/LON for the second waypoint until the first is sequenced.

Question 10

What should be done when operating on routes where CPDLC will be used?

Answer 10

Position the FMC Selector to the FMC listed as (PRI) on the POS REF page 3/3.

Question 11

If the engine anti-ice system is not restored following completion of the ANTI-ICE ENG L, R NNC, what can be done?

Answer 11

Cycle the engine anti-ice selector OFF then ON up to 5 times.

Question 12

What should be done with loss of engine thrust control?

Answer 12

Engine Limit/Surge/Stall checklist, except for a failure to a high power setting on the ground, when the flight crews should shut down the malfunctioning engine immediately.

Question 13

Should the crew open the fuel crossfeed valve after an in-flight engine shutdown?

Answer 13

Flight crews should keep the fuel crossfeed valve closed unless directed to open the valve by a non-normal checklist.

Question 14

What should the flight crew do if the ELEC BUS ISLN L and ELEC BUS ISLN R EICAS messages occur simultaneous during engine start, pushback or taxi phases of flight?

Answer 14

Flight crews may reset the Bus Tie Switches without checking for correlated maintenance messages on the ground only. If at all possible, this procedure should be done while in contact with engineering/MCC.

Question 15

When should alternate CG be selected in the OPT?

Answer 15

When the takeoff MAC on the loadsheet is 26% or greater.

Question 16

What should be done in case of a tail strike without the EICAS caution message TAIL STRIKE on the 777-300? And the 777-200?

Answer 16

Crews should continue the flight on the 300, but return to land when on the 200.

Question 17

What should the crew do to avoid overspeeding in cruise?

Answer 17

Temporarily deploy partial speed brakes.

Question 18

Which engine conditions should crews be aware of regarding the GE90 engine?

Answer 18

The bowed rotor starts with N2 vibration, starter air valve being slow to open leading to a ENG AUTOSTART L/R message and oil gulping.

Question 19

When will a CONFIG GEAR STEERING warning message appear?

Answer 19

N1 exceeds 60% and main gear PCA is in the unlocked position.

Question 20

If a loss of power to the Right Transfer bus is suspected after approach mode is selected, what can be done?

Answer 20

De-select and reselect approach mode.

Question 21

Should the auto land be used for overweight landings?

Answer 21

No.

Question 22

If an AFDS anomaly is observed where individual pilot-selected AFDS modes are not responding normally to MCP switch selections, what can be done?

Answer 22

Attempt to correct the problem by disconnecting the autopilot and selecting both flight director switches to OFF.

Question 23

What can be done in case of excessive ground returns from the weather radar?

Answer 23

Deselect weather radar on both EFIS control panels for more than one second. Reselect as needed.

Question 24

Are all fire warnings to be considered genuine?

Answer 24

No, they could be spurious due to hair spray, smoking in lavatories and insecticide spraying. Further investigation might be warranted before deciding on action to be taken.

Question 25

What should be done if the left and right LRRA disagree significantly, or if either one appears to be providing an erroneous altitude reading?

Answer 25

Automation should be disengaged.

Question 26

What are some symptoms for ice crystal icing?

Answer 26

High altitude, in clouds, overflying strong weather returns, appearance of rain on the windscreen, possibly TAT near zero, light to moderate turbulence. Pilot reports from events vary and not all the symptoms noted above are reported in every event.

Question 27

What should be done if ice crystal icing is suspected?

Answer 27

Exit ice crystal icing conditions. Request a route change to minimize time above red and amber radar returns.

Question 28

What does the message RUNWAY SYS EICAS Advisory/Status indicate?

Answer 28

If occurring on the ground prior to take-off or on final approach this message indicatesthat the Smart Runway and Smart Landing advisories are not available to the flight crew.
