- Discontinuities between two waypoints in the flight plan
- Discontinuities after a MANUAL leg (Manual Termination)

!!! warning "STAR and Approach Discontinuity - Inaccuracy"
If your STAR contains other waypoints after the IAF (initial approach fix) that you have selected via an approach transition (VIA), the FMS will not automatically connect the STAR to the approach at the IAF.

This is a small problem with our current implementation. It will be corrected when we update to version 2 (fms-v2) of our implementation, which contains even better simulation of the Honeywell FMS.

!!! warning "SID and En-route F-PLN Discontinuity - Inaccuracy"
**In most cases** a discontinuity between the SID and your route is something that doesn't happen in real life.

With our current FMS, the A32NX sometimes will create a discontinuity that wouldn't typically be there. In these cases it would be okay to CLR the discontinuity -

There are some important things to note why you shouldn't normally clear a discontinuity:

- Turn radius between the two waypoints where the discontinuity is present
- Narrow turn radii between the two waypoints, where the discontinuity is present, which could not be flown by the plane

- Even if the waypoints form a direct line, it's not inherently completely safe to remove a discontinuity unless you understand the above points

## Discontinuities Between Waypoints

!!! warning ""
These discontinuities **should not** be cleared from the flight plan in normal operations.

Typically, you will notice a discontinuity in the following instances:
