Federal Aviation Administration 

Agency Information Collection 

Activities: Requests for Comments; 

Clearance of Renewed Approval of 

Information Collection: General 

Operating and Flight Rules 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice and request for 

comments. 

SUMMARY: In accordance with the 

Paperwork Reduction Act of 1995, FAA 

invites public comments about our 

intention to request the Office of 

Management and Budget (OMB) 

approval to revise a previously 

approved information collection. Part A 

of subtitle VII of the Revised title 49 

U.S.C. authorizes the issuance of 

regulations governing the use of 

navigable airspace. Information is 

collected to determine compliance with 

Federal regulations. This revision 

addresses requirements from the 

Enhanced Flight Vision Systems (EFVS) 

Rule, RIN 2120–AJ94. 

DATES: Written comments should be 

submitted by March 25, 2016. 

ADDRESSES: Send comments to the FAA 

at the following address: Ronda 

Thompson, Room 441, Federal Aviation 

Administration, ASP–110, 950 L’Enfant 

Plaza SW., Washington, DC 20024. 

PUBLIC COMMENTS INVITED: You are asked 

to comment on any aspect of this 

information collection, including (a) 

Whether the proposed collection of 

information is necessary for FAA’s 

performance; (b) the accuracy of the 

estimated burden; (c) ways for FAA to 

enhance the quality, utility and clarity 

of the information collection; and (d) 

ways that the burden could be 

minimized without reducing the quality 

of the collected information. The agency 

will summarize and/or include your 

comments in the request for OMB’s 

clearance of this information collection. 

FOR FURTHER INFORMATION CONTACT:

SUPPLEMENTARY INFORMATION: 

OMB Control Number: 2120–0005. 

Title: General Operating and Flight 

Rules. 

Form Numbers: None. 

Type of Review: Revision of an 

information collection. 

Background: The reporting and 

recordkeeping requirements of Federal 

Aviation Regulation (FAR) part 91, 

General Operating and Flight Rules, are 

authorized by part A of subtitle VII of 

the Revised title 49 U.S.C. FAR part 91 

prescribes rules governing the operation 

of aircraft (other than moored balloons, 

kites, rockets and unmanned free 

balloons) within the United States. The 

reporting and recordkeeping 

requirements prescribed by various 

sections of FAR part 91 are necessary for 

FAA to assure compliance with these 

provisions. 

Respondents: Approximately 21,200 

airmen, state or local governments, and 

businesses. 

Frequency: Information is collected 

on occasion. 

Estimated Average Burden per 

Response: .5 hour. 

Estimated Total Annual Burden: 

235,183 hours.

BILLING CODE 4910–13–P 

DEPARTMENT OF TRANSPORTATION 

Federal Highway Administration 

National Standards for Traffic Control 

Devices; the Manual on Uniform Traffic 

Control Devices for Streets and 

Highways; Notice of Termination of 

Interim Approval IA–5 

AGENCY: Federal Highway 

Administration (FHWA), Department of 

Transportation (DOT). 

ACTION: Notice. 

SUMMARY: The Manual on Uniform 

Traffic Control Devices for Streets and 

Highways (MUTCD) is incorporated in 

our regulations, approved by FHWA, 

and recognized as the national standard 

for traffic control devices used on all 

streets, highways, bikeways, and private 

roads open to public travel. This notice 

terminates the Interim Approval for Use 

of Clearview Font for Positive Contrast 

Legends on Guide Signs (IA–5), issued 

September 2, 2004, as authorized by 

Section 1A.10 of the MUTCD, and 

discontinues the provisional use of an 

alternative lettering style in traffic 

control device applications. The result 

of this termination rescinds the use of 

letter styles other than the FHWA 

Standard Alphabets on traffic control 

devices, except as provided otherwise in 

the MUTCD. Existing signs that use the 

provisional letter style and comply with 

the Interim Approval are unaffected by 

this action and may remain as long as 

they are in serviceable condition. This 

action does not create a mandate for the 

removal or installation of any sign. This 

action does not amend any provision of 

the MUTCD. 

DATES: Effective 30 days after 

publication in the Federal Register. 

FOR FURTHER INFORMATION CONTACT: For 

questions about this notice, contact Mr. 

Kevin Sylvester, MUTCD Team Leader, 

FHWA Office of Transportation 

Operations, (202) 366–2161, or via email 

at Kevin.Sylvester@dot.gov . For legal 

questions, please contact Mr. William 

Winne, Office of the Chief Counsel, 

(202) 366–1397, or via email at 

William.Winne@dot.gov. Office hours 

are from 8:00 a.m. to 4:30 p.m., e.t., 

Monday through Friday, except Federal 

holidays. 

SUPPLEMENTARY INFORMATION: 

Background 

Numerous research efforts have taken 

place over the last 15 years with the goal 

of improving the legibility of highway 

signs. One area of focus has been on 

guide signs. As a result of some early 

studies,1 FHWA issued an Interim 

Approval allowing provisional use of an 

alternative lettering style known as 

ClearviewTM for signs in positive 

contrast color orientations (lighter 

legend on darker background).2

Although the research supported only 

one series of this lettering style, the 

Interim Approval was written in a way 

that would authorize narrower letter 

forms, to correspond to the system of 

the FHWA Standard Alphabets, in 

anticipation of successful future 

research evaluations. However, 

subsequent evaluations showed no 

benefit to the narrower letter forms and 

degraded sign legibility when compared 

to the corresponding FHWA Standard 

Alphabet series.3 Additionally, tests of 

alternative lettering in negative contrast 

color orientations (dark legend on 

lighter background, such as for 

regulatory and warning signs) showed 

no improvement and significantly 

degraded legibility of the sign.4
