How is the vertical speed typically displayed on EFIS-equipped aircraft?
  • A
    A vertical speed tape, with one white arrow that indicates climb, descent or zero.
  • B
    A vertical speed tape with three arrows, one each to indicate climb, descent or zero.
  • C
    A vertical speed tape with two arrows, one green to indicate a climb and one red to indicate a descent.
  • D
    EFIS-equipped aircraft generally have no vertical speed indication.

Refer to figure.
The EADI (or PFD) presents a dynamic colour display of all the parameters necessary to control the aircraft, and that the main layout conforms with the basic-T principle:

- Attitude information in the centre
- Airspeed information on the left
- Altitude information on the right
- Vertical speed
- Heading/track indication in the lower centre
- Flight mode annunciation at the top
- Takeoff and landing reference speeds along the airspeed tape and in the bottom right
- Minimum airspeed at the bottom of the airspeed tape
- Lower selectable airspeed at the top of the airspeed tape and adjustable from the speed window and speed selector on the MCP
- Mach number just below the airspeed tape

Vertical speed is displayed to the right of the altitude tape with a white tape and pointer. Vertical speed is digitally displayed above or below the vertical speed display when vertical speed is greater than a defined value of feet per minute. It is displayed above with positive vertical speed and below with negative vertical speed.
