Modified waypoint constraints are shaded white until they are executed. Speed
constraint entries require an altitude constraint at the same waypoint. All speed
constraints are considered by the FMC as at or below constraints.
At or above altitude constraints are entered with a suffix letter A (example: 220A).
At or below altitude constraints are entered with a suffix letter B (example: 240B).
Mandatory altitude constraints are entered without any suffix letter (example:
270).
Altitude constraints with two altitudes may be entered in either order. The lower
altitude constraint, followed by a suffix letter A, and the upper altitude constraint,
followed by a suffix letter B (example: 220A240B or 240B220A).
