The FAA recently made changes to Operational Specification/Management Specification (MSPec)/Letter of Authorization (LOA) B045, Extended Overwater Operations Using a Single Long-Range Communication System. The changes affect FAR Part 91K, 121, 125 and 135 operators utilizing a single long-range communication system (SLRCS) in the West Atlantic Route System (WATRS), Caribbean or Gulf of Mexico.

The current template for B045 is combined for Parts 121, 152 and 135, which causes confusion for operational control organizations. It also contains contradicting information regarding the various communication requirements for each regulatory part. The current template allows a gap of up to 30 minutes in very high frequency radio coverage; however, Parts 121, 125 and 135 do not contain time restraints for SLRCS in this area.

New separate templates have been created for each of the regulatory classifications. Operators must obtain the mandatory new approval by April 23, 2015. The new templates are tailored for the operational control organization and clarify the communication requirements of each part. The changes provide for greater planning flexibility while maintaining high levels of voice communication reliability. Review the new templates.
