2016 PG Guide - Cruise

Question 1

Challenge - Response - Response

You have a non-normal situation occurs at cruise altitude. Using the “Challenge-Response-Response” method, you accomplish the QRH/QRC checklist.

What is the job of the PM and PF using this method?

Answer 1

PM - read the checklist item then give the response

PF - Verify / guard critical items or systems, then repeat the response

PM - Accomplish the action

Question 2

FMC Descent Programming

You decide to program the FMC Descent Forecast Page with the proper descent winds and temperature / altimeter setting.

How do you calculate the proper ISA deviation?

Answer 2

On a standard day, the temperature at FL180 is approximately -21C. Refer to the enroute wind and temperature summary on the Dispatch Release.

Calculate the difference between the forecast temperature at FL180 and the ISA Temperature (-21C), and enter that value.

For example, the release shows a forecast temperature at FL180 of -16C, or 5 degrees warmer than ISA. You should enter +5 into the FMC.

Question 3

Standby Power OFF

You’re at cruise in your NG aircraft and get a STANDBY POWER OFF light. What does this indicate? What does this light indicate in the CL?

Answer 3

NG - The battery bus, AC Standby Bus or DC Standby Bus (or any combination) is/are unpowered.

CL - The AC standby bus is unpowered only.

NG & CL - The light functions both on the ground and in the air

Question 4

Cargo Bay Fire

You have accomplished the CARGO BAY FIRE Checklist including the pressing of the FWD discharge button. How soon must you land.

Answer 4

60 minutes

ETOPS - 195 minutes

Question 5

APU Limitations

You experience an engine failure in a CL at FL370. You attempt to start the APU immediately, but it fails to start. What should you do before you attempt another start?

Answer 5

Max operating altitude for the APU in the CL is FL350.

Wait 90 seconds and descend below FL350 before attempting another start.

Question 6

Tripped Circuit Breaker

While airborne, you just received an indication from the A Flight Attendant that the Wireless Broadband System is not working. You notice that the Broadband Control DC circuit breaker (P6-1-B-17) has tripped. Can you reset the circuit breaker?

Answer 6

No

The in-flight reset of a tripped circuit breaker should only be accomplished when directed by the QRH.

Question 7

Driftdown

At FL370, as the PF, you experience a #1 engine failure. If drift down is required, how do you perform the drift down maneuver?

Answer 7

• Disconnect auto throttle if engaged. Manually set CON thrust
• Set engine out MAX ALT in the MCP.
• Select LVL CHG
• Set ENG OUT SPD in the MCP Initiate turn (if required)
• At single engine altitude, maintain CON thrust

Question 8

Driftdown

At FL370, as the PM, you experience a #1 engine failure. If drift down is required, what are your duties during the drift down maneuver?

Answer 8

• Select CON thrust in the FMC
• Select L ENG OUT on the FMC CRZ page
• Notify ATC
