Notes: 

<img src='content_image/520533.jpg'>

(1) When the predicted residual risk is unacceptable (high), AOV approval is not required. 

(2) Per Safety Management System policy, a high predicted residual risk is unacceptable and the NAS change in question must not be implemented. The SMTS submitter is responsible for notating this in SMTS and closing out the safety analysis. (See the SMTS User Manual.) 

(3) Signature responsibility may only be delegated from a Director to a Deputy Director. 

(4) For local changes, the SRM document is signed one level above the ATM at the facility completing the SRM document. For ARTCC ATMs, this is the Service Area Director of Operations; for Terminal ATMs, this is the District Manager or General Manager; and for Technical Operations Managers, this is the Technical Operations District Manager or General Manager.
