Target Speed (TGT SPD)
Displays the computed speed required to meet the RTA.
When RTA mode is exited by waypoint sequence or by deletion, this speed
becomes the FMC target speed on a manual speed cruise page and the scratchpad
message SELECT MODE AFTER RTA is displayed.
TIME ERROR
Displays the computed time error at the RTA waypoint.

Fuel at Destination with Step Climb Altitude (FUEL AT XXXX)
The computation assumes the step climb will occur at the STEP point, and the
value is prefixed by W/STEP.
Step To Altitude (STEP)
Used to enter step climb or step descent altitudes for crew evaluation.
Blank when within 100 nm of top of descent or when RTA mode is active.
STEP POINT
Displays the computed ETA at, and distance to, the first possible step climb point based on gross weight.
Blank if no entry on STEP TO line.
Wind (ACTUAL WIND or EST WIND)
Used as the assumed true wind at the STEP TO altitude for making wind–altitude trade computations.

Savings/Penalty (SAVINGS or PENALTY)
Displays the predicted cost savings or penalty associated with flying the displayed speed/altitude step climb or descent profile, as compared to flying the current cruise speed schedule and maintaining present altitude to top of descent.
Blank if no step data entered.
Cruise Climb
The cruise climb page displays data for a cruise climb to a new altitude.
MOD CRZ CLB is automatically displayed during cruise if a higher cruise altitude
is entered on the CRZ page.
During VNAV operation, execution initiates a climb at climb thrust and cruise
target speed to the new altitude.
The VNAV climb mode is active until reaching the selected altitude. The mode
then automatically changes back to cruise.

Cruise Descent
The cruise descent page displays data for a cruise descent to a new altitude.
MOD CRZ DES is automatically displayed during cruise if a lower cruise altitude is entered on the CRZ page. During VNAV operation, execution initiates a descent at 1,000 feet per minute and
cruise target speed to the new altitude. YA613 - YC413, YK101 - YK104
