The average cruise wind component may be entered as either a tailwind or a
headwind. A tailwind is entered by entering a leading slash (/) and a +, followed
by the desired value, into the SP and then pushing 6L. Alternatively, the flight
crew may enter the leading slash (/) followed by the alpha character(s) T, TL, or
TAIL, followed by the value. The entered value will be displayed in 6L preceded
by TL. A headwind is entered by the same methods except the + is replaced by a
- and the T is replaced by an H, HD, or HEAD. The entered value in this case
would be preceded by HD. The default windspeed is 0 knots, headwind, but a
correct value will help the FMS compute better predictions on fuel consumption
for the flight.
Optimum and maximum flight levels are displayed in line 6 for flight crew
information only.
The cost index in 6R reflects time cost relative to fuel cost, and can range from 0
to 999. This field will remain dashed and not allow any entries until an active
primary destination is entered or engines are started. Once the destination is
entered, the cost index is either taken from the nav database for the company route,
or is flight crew-entered. It is recommended that this not be entered until the flight
plan is strung.
