Locking a bank angle parameter and a ground speed parameter

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a flight management system (FMS) of an aircraft, cause the FMS to:
• determine that a leg of a lateral trajectory profile, which is associated with a flight plan for the aircraft, is active;
• determine, based on determining that the leg of the lateral trajectory profile is active, a lateral distance threshold associated with an end waypoint of the leg;
• determine whether a lateral distance between the aircraft and the end waypoint satisfies the lateral distance threshold;
• and
• selectively perform one of:
• a first update to the lateral trajectory profile, based on determining that the lateral distance satisfies the lateral distance threshold, to lock a bank angle parameter to a particular bank angle value at which a bank angle of the aircraft has been set, or
• a second update to the lateral trajectory profile, based on determining that the lateral distance does not satisfy the lateral distance threshold, to set the bank angle parameter to another bank angle value.

A method, comprising:

• and
• selectively performing one of:
• a first update to the lateral trajectory profile, based on determining that the lateral distance satisfies the lateral distance threshold, to lock a bank angle parameter to a particular bank angle value, or
• a second update to the lateral trajectory profile, based on determining that the lateral distance does not satisfy the lateral distance threshold, to set the bank angle parameter to another bank angle value.
