2016 PC Guide - Pushback Flashcards
Inoperative APU
You’re at the gate with an inoperative APU and require a ground air start. Which engine will you start first and why?
Engine 1
To minimize hazard to ground crew who do most of their work on the #2 side of the aircraft.
Inoperative APU
What is the minimum duct pressure required for the ground air start?
CL
- 30 psi allowing for 0.5 psi reduction for every 1000 feet Pressure Altitude
NG
- Not applicable
Inoperative APU
After engine start and prior to push from the gate, what must be accomplished before placing the #1 generator online?
Verify with Ground Crew that the tower and nose wheel are aligned prior to placing generator on the buses.
Inoperative APU
After pushback is complete and the ground crew has departed, you determine a two-engine taxi is appropriate and need to perform a Crossbleed start. What must the crew first do? How much Duct Pressure is required to start?
Ensure the area behind the aircraft is safe to perform the crossbreed start.
Advance the thrust lever to obtain a minimum duct pressure of 30 psi (subtract 0.5 psi per 1000 feet above sea lever).
Towbar
After pushback has commenced, do not make ________ or ________ power changes with the towbar connected.
Electrical or Hydraulic
Engine Start
You are starting the #2 engine. Before the start lever is raised to IDLE you notice no N1 rotation. What should you do?
Accomplish the aborted engine start checklist in the QRC.
Start Valve Open
During the Engine Start, the START VALVE OPEN alert comes on and starts flashing. What is the proper procedure to deal with this problem?
Perform the QRH “Start Valve Open” check list.
After Start Flow
After starting the first engine (through the rollback) what is the only after start flow item the is allowed prior to Pushback Crew departure?
Configure the Air Conditioning panel as appropriate for conditioned air.
Single Engine Taxi
You have completed a normal pushback and start of the #2 engine. You elect to single engine taxi. How will you configure the Bleed Air control panel
R Pack - Auto/High Isolation Valve - Closed L Pack - Auto/High L Engine Bleed - OFF APU Bleed - ON R Engine Bleed - ON
Runway Change
After pushback, If the taxi clearance is to a runway different from the runway planned in the FMC, what must be accomplished?
Program the correct runway in the FMC, confirm takeoff performance on OPC, and re-accomplish the Pilot Flying Briefing. Conduct the Departure Plan Checklist. This must be done either prior to taxi or coordinate to stop the aircraft prior to takeoff.
Engine Shutdown During Taxi
After a two engine start, you decide to single engine taxi. Do the engine idle limitations for Engine Shutdown apply to a shutdown following ramp departure.
No
Taxi Thrust
During single and duel engine taxi use caution when exceeding the following recommended thrust values:
_____ % N1 on congested ramps
_____ % N1 on non-congested ramps
_____ % N1 on taxiways
35% N1 on congested ramps
40% N1 on non-congested ramps
45% N1 on taxiways
Hot Weather Operations
You are planning a two engine taxi in hot weather. What is the recommended configuration for maximum cooling air to the Passengers?
R & L Pack switches - Auto/High Isolation Valve - Closed L Engine Bleed - OFF APU Bleed - ON R Engine Bleed - ON
LNAV Armed on the Ground
In an NG, with LNAV armed on the ground, LNAV guidance becomes active at _____ ft AGL.
50 ft.
Takeoff Visibility
Southwest Airlines in not authorized for takeoff visibility below _____ RVR unless the Jeppesen -9A page lists HGS _____ RVR.
500
300
