HTAWS shall NOT be used for navigation purposes.

the pilot can be assured of maintaining clearance from terrain and obstacles.
RP Mode shall only be used when in visual contact with terrain.
External HTAWS annunciators installed in the aircraft shall be fully functional
in order to use the HTAWS system.
The external "HTAWS ALERT ACK" switch shall be used in lieu of the Alert

around areas of hazardous weather.
The indicated data link weather product age shall not be used to determine the

shown by the data link weather product may be significantly older than the
indicated weather product age.

Restriction (TFR) or Notice to Airmen (NOTAM) information. Not all TFRs
