As a result, two routes for every CLT location will be allocated: one route for EFVs
and the other one for EUF vehicles.
are inexpensive to install when a service line is first installed or later replaced, but significantly more expensive to retrofit on an existing service or replace if the valve fails or a customer installs gas-burning equipment that requires more gas than the EFV
will allow through the service line.
"APGA supports the EFV
installation portion of the rule proposed by PHMSA," states Erickson.
The study discussed in this paper aims at understanding how a general positive attitude toward the environment results in a limited purchase of EFVs
. To do so we adopt the principles of Information Integration Theory (IIT) on Attitude Integration (Anderson, 1981, 1982, 2008) and its methodological counterpart, Functional Measurement (FM).
We hypothesize that the cluster of viral meningitis cases and the EFVS
were different manifestations of the same infection, caused by a strain of echovirus type 4 (E4) virus.
A fully-interactive InSight Display System + Heli-ClearVision EFVS

has announced Federal Aviation Administration (FAA) has granted approval for visual advantage credit using Enhanced Flight Vision System (EFVS
) for its fleet of in-production aircraft, the company said.
There has been a push for over a decade to expand the use of EFVs
. The National Transportation Safety Board (NTSB) has been a leading advocate based on investigations and recommendations it has issued going back to a 1998 incident in South Riding, Virginia.
Elbit Systems developed a unique Head-Up-Display System including Enhanced Flight Vision System (ClearVision* EFVS
), Synthetic Vision System (SVS) and Combined Vision System (CVS), which will allow pilots of Falcon business jets to land safely even in low-visibility conditions.
Among the requirements is that LDCs must install excess flow valves (EFVs
) when constructing a new or replacement service to a single-family residence or when the connection between a single-family service line and the main are replaced under most conditions.
Plans to purchase 1,025 EFVs
been sharply curtailed.
FAR 91.175 was recently changed to allow certain operators to use the view through Enhanced Flight Vision Systems (EFVS
) in meeting the visibility criteria for an instrument approach.
