Flight crew entered or uplinked values replace previously displayed values.
Entry of a value after takeoff speeds have been accepted deletes takeoff speeds and
displays the CDU help window message TAKEOFF SPEEDS DELETED.
OAT defaults to ºC unless a manual OAT ºF entry has been made. When SEL
temperature is in ºF, the OAT also displays in ºF.
When OAT is not available, the slash is followed by box prompts allowing manual
OAT entry using one of the following formats:
• /SNN where S represents the sign and NN is a temperature value in the
range of -99 to +60 inclusive
• /SN where S represents the sign and N is a single digit temperature value in
the range of 0 to 9 inclusive
• /NN where NN is a two digit positive temperature value in the range of 00
to 60 inclusive, and
• /N where N is a single digit positive temperature value in the range of 0 to
9 inclusive
• a Fahrenheit entry must include an “F” as the last character
The assumed temperature thrust derate is not the same as TO 1 and TO 2 fixed
thrust derates described below. If TO 1 or TO 2 is selected and an assumed
temperature is then entered, thrust is further derated.
If entry results in greater than a 25% reduction in thrust, the entered value is dialed
back to a value that results in a 25% reduction.
Push – selects full rated (TO) takeoff thrust limit.
Selection of a new rating after takeoff speeds have been accepted deletes takeoff
speeds and displays the CDU help window message TAKEOFF SPEEDS
DELETED.
Push – selects fixed percentage derate (TO 1) for takeoff thrust limit.
Takeoff thrust derate can also be entered by accepted uplink.
TO 1 default thrust derate can be modified on the AIRLINE POLICY page.
Selecting TO 1 arms the appropriate climb thrust (CLB, CLB 1 or CLB 2). (Refer
to Derated Thrust Climb
in Chapter 11, Section 32, for additional information.)
Selection of a new TO 1 rating after takeoff speeds have been accepted deletes
takeoff speeds and displays the CDU help window message TAKEOFF SPEEDS
DELETED.
Push – selects fixed percentage derate (TO 2) for takeoff thrust limit.
Takeoff thrust derate can also be entered by accepted uplink.
