1.4 Operational and Legal Issues
The information displayed on the ST3400H is generated by external
equipment. It is the pilot’s responsibility to ensure the correct
configuration and use of the external equipment. The ST3400H is subject
to all legal and operational limitations of the equipment supplying data to
it. Always refer to your approved Rotorcraft Flight Manual Supplement
for operation and limitations on the use of installed equipment.
Note: Because aircraft vary in their installed equipment, it is important to
note that what is displayed on the ST3400H may vary depending on the
presence or absence of equipment.
Please keep in mind that it is required by Federal Aviation Regulations to
have on board current charts appropriate to the flight. The moving map on
the ST3400H does not fulfill this requirement. Current internal databases
are not required but are recommended. The internal databases supply
supplemental data only (such as nearest airports and obstacles). Flight plan
waypoints are supplied to the ST3400H by the associated approved GPS
receiver.
Supplemental data is intended for positional awareness only.
