Revisions to Operational Requirements for the Use of Enhanced 
Flight Vision Systems (EFVS) and to Pilot Compartment View Requirements 
for Vision Systems; Extension of Comment Period

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM); extension of comment 
period.

-----------------------------------------------------------------------

SUMMARY: This action extends the comment period for an NPRM that was 
published on June 11, 2013. In that document, the FAA proposed to 
permit operators to use an EFVS in lieu of natural vision to continue 
descending from 100 feet height above runway touchdown zone elevation 
and land on certain straight-in instrument approach procedures under 
instrument flight rules. This rule would also permit certain operators 
using EFVS-equipped aircraft to dispatch, release, or takeoff under 
instrument flight rules (IFR), and to initiate and continue an 
approach, when the destination airport weather is below authorized 
visibility minimums for the runway of intended landing. Pilot training, 
recent flight experience, and proficiency would be required for 
operators who use EFVS in lieu of natural vision to descend below 
decision altitude, decision height, or minimum descent altitude. EFVS-
equipped aircraft conducting operations to touchdown and rollout would 
be required to meet additional airworthiness requirements. This rule 
would also revise pilot compartment view certification requirements for 
all vision systems. Given the technical complexity of the NPRM, 
Dassault-Aviation has requested that the FAA extend the comment period 
to October 15, 2013 to allow time to adequately analyze the NPRM and 
provide meaningful comments.

DATES: The comment period for the NPRM published on June 11, 2013, was 
scheduled to close on September 9, 2013, and is extended until October 
15, 2013.

SUPPLEMENTARY INFORMATION:  See the ``Additional Information'' section

information on obtaining copies of related rulemaking documents.

Background

    On June 11, 2013, the FAA issued Notice No. 1209, entitled 
``Revisions to Operational Requirements for the Use of Enhanced Flight 
Vision Systems (EFVS) and to Pilot Compartment View Requirements for 
Vision Systems'' (78 FR 34935). Comments to that document were to be 
received on or before September 9, 2013.
    Dassault-Aviation submitted an electronic request for an extension 
of the comment period from September 9, 2013 to October 15, 2013. The 
petitioner requested this extension to allow adequate time to evaluate 
and prepare comments for the NPRM and two draft Advisory Circulars 
(ACs) which are directly related to the NPRM. On August 13, 2013, the 
FAA published a Notice of Availability (78 FR 49318) making draft AC 
90-106A, Enhanced Flight Vision Systems, and draft AC 20-167A, 
Airworthiness Approval of Enhanced Vision System, Synthetic Vision 
System, Combined Vision System, and Enhanced Flight Vision System 
Equipment, available for public comment. The comment period for both 
ACs closes on October 15, 2013. The petitioner asserted that comments 
to the NPRM should be linked with comments to both draft ACs, and that 
the comment period for the NPRM should therefore be extended to October 
15, 2013 to match the comment period closing date for the draft ACs. 
The petitioner further asserted that doing so would provide them with 
adequate additional time to evaluate and provide comments for all three 
documents. The FAA agrees with the petitioner's position and is 
granting an extension of the comment period to October 15, 2013.

Extension of Comment Period

    In accordance with Sec.  11.47(c) of title 14, Code of Federal 
Regulations, the FAA has reviewed the petition made by Dassault-
Aviation for extension of the comment period to the NPRM. This 
petitioner has shown a substantive interest in the proposed rule and 
good cause for the extension. The FAA has determined that extension of 
the comment period is consistent with the public interest, and that 
good cause exists for taking this action.
    Accordingly, the comment period for the NPRM Notice No. 1209 is 
extended until October 15, 2013.
