Issue
When a database uses different coordinate systems for storage and input/output, the GML command retrieve_travel ignores the measurement unit given.

Solution
Meters are the hard-coded default for all latitude/longitude-derived coordinate systems. Therefore, it is necessary to convert the travel distance to meters when you are using different coordinate systems for the storage and input/output of your data.
This can be done either by multiplying by a known scaling factor, or using the GML command retrieve unit_conversion as follows:
setup coordinate system {fe_ll};
retrieve unit_conversion length for $distance_feet into distance_metres;
setup coordinate system {fe_lc};
