What is the equipment suffix for GNSS capable aircraft?

The equipment suffix for GNSS (Global Navigation Satellite System) capable aircraft is indeed designated with the suffix /G. This designation is specifically used in flight plans to indicate that an aircraft is equipped with GNSS technology, which encompasses systems like GPS and others that provide satellite-based navigation.

The other suffixes, such as /L for Long-Range Navigation and /S for Standard navigation equipment, refer to different capabilities. While multiple suffixes may represent various navigation technologies used by aircraft, the /G specifically identifies GNSS capability, making it an essential suffix for ensuring accurate and compliant flight planning.

The inclusion of options like /L and /S within the framework may lead to confusion since they pertain to other types of navigation systems that might coexist with GNSS but do not represent it exclusively. Therefore, the suffix /G is the appropriate designation for all aircraft equipped with GNSS technology, clearly distinguishing it as the correct answer in this context.
