We present a list of basic modes and which of them are most useful.
We also explain how to operate the multifunction buttons of the autopilot panel.
The autopilot is best explained by a practical example of flight in the next chapter of this guide.
These are:
In addition, the main functions, i.e.
So you’re gonna wanna know when you’re doing what action.
Enabling autopilot
The most important button isAP 1to activate the autopilot.
AP 2 is usually used by the first officer on his side.
Just below them isA/THR- Auto Throttle, which turns on automatic throttle control, and therefore speed.
Normally, during the flight, these two functions will be turned on almost all the time.
The Autopilot is indicated by the glowing green inscriptionNAVon the PFD screen.
The LOC (localiser) and APPR (approach) buttons are used just before the automatic landing approach.
These functions are described in more detail in the chapter on ILS landing in an example passenger flight.
The aircraft then selects all other flight parameters for this priority.
You will use this mode most often, along with NAV Mode and scheduled flight.
Clicking on the button perimeter sets the knob to adjust altitude every 100 or every 1,000 feet.
The specified height appears as blue numbers on the PFD.
Next button described asSPD/MACHswitches the speed display unit from knots to Mach.
Normally you will not use it during the flight unless there is an emergency.
During a standard flight, there will be no need to activate this mode.
Its operation is further described in the example flight section and the ILS landing page.
LOC, or localizer, is used to automatically position the aircraft on the axis of the belt.
Align them with the yellow bars to indicate the correct descent to landing path.
So there are some minor differences in the handling of Boeing’s autopilot.
Switch off with the lower leverDISENGAGE.
To reactivate the autopilot after disengaging, you must first slide the Disengage lever back into place.
All three CMD - L, C and R lights should be on during final approach and APPR mode.
There are big differences when ascending or descending to the programmed altitude.
When the ALT-programmed limit is reached, V/S mode will automatically shut down.
Use theA / T ARMSwitch.
The switch that’s not on the Airbus isBank Limit.
It defines the limit in the tilt of the aircraft during an automatic change of course (turns).
It can be automatic or from 5 to 25 degrees tilt.
The greater the angle, the faster the turn, but less comfortable for passengers.
