Nothing
What occurs when Vertical Speed is selected with the Autothrottles engaged?
V/S engages and the A/T engage in the MCP SPEED mode
Autothrottle operation is available with Flight Directors___ or with the Autopilot engaged or not engaged
ON or OFF
What does the ON light in a MCP mode selector switch indicate?

Which statement is correct when an A/P is engaged in CMD and pressure is applied to the control wheel or column
Autopilot paddle switch remains in CMD; CWS P or CWS R is displayed on the FMA
What occurs when an A/P is engaged in CMD and pressure is applied to the control wheel or column
Pitch and/ or roll modes revert to CWS
What will cause a single AP to disengage
All answers are correct
During cruise flight in VNAV, only one autopilot may be engaged.
YES
Which statement is correct regarding A/P operation with the paddle switch in CWS
A/P maneuvers airplane in response to control pressures applied by either pilot
With the autopilot in CWS ROLL and ALT HOLD, the pilot rolls the aircraft into 15 degrees of bank and releases the controls. The aircraft will
Maintain 15 degrees of bank and hold altitude
With the A/P engage paddle in CZmD mode, how can CWS pitch mode be engaged
CMD mode may be overridden to CWS pitch by forward or aft pressure on the flight controls
Which mode is only a Flight Director mode and not an autopilot mode
Takeoff
Which are roll modes only

Which are pitch modes
LVL CHG, VNAV, ALT HOLD
How is the ALT ACQ mode engaged
Automatically when climbing or descending in VS or LVL CHG modes
What mode engages automatically when ALT ACQ is engaged and a new MCP altitude is selected
VS engages if selected altitude differs by more than 100 feet from previous selected altitude
How is the LVL/CHG mode selected
Select new MCP altitude , push the LVL CHG sw
What speed will be displayed in the IAS/MACH speed window when LVL CHG is selected from VNAV
IAS/MACH display and airspeed cursors synchronize to existing speed
Which statement is correct regarding capture of a selected VOR course
Capture point depends on intercept angle & closure rate
Which statement regarding capture of the LOC &GS is correct when operating in the APP mode
LOC must be captured first, then GS may be captured
