In flight, the flight path acceleration symbol is positioned to the left of the flight
path symbol. When flight path acceleration symbol is above the wing of the flight
path symbol, the airplane is accelerating. When it is below the flight path symbol
wing, the airplane is decelerating. To maintain a steady state (neither accelerating
nor decelerating), the flight path acceleration symbol is positioned directly to the
left of the left flight path symbol wing. When the airplane is not in flight, or the
flight path symbol is not displayed, then the flight path acceleration symbol is
referenced to the airplane reference symbol.
To avoid confusion in controlling airplane thrust, the flight path acceleration
symbol is removed from the display when a low-level, decreasing performance
windshear is detected below 400 feet AGL.
Ground Deceleration (Rate) Scale
A ground deceleration rate scale is shown on landing or when a deceleration is
sensed on takeoff. A vertical indexed scale and pointer indicate the actual
deceleration rate being achieved, as provided by the corresponding autobrake
setting (1, 2, 3, 4, MAX AUTO).
During takeoff, the scale is not displayed, but is added to the display if a
deceleration is sensed when the groundspeed is above 50 knots, and the airplane
is still on the ground. Once displayed, the scale is removed when groundspeed
decreases below 25 knots, the airplane begins accelerating, or the airplane lifts off.
