Background
On April 13, 2000, the FAA published a final rule modifying the Houston, TX, Class B airspace area (65 FR 19826). The modified Class B airspace area, implemented on June 15, 2000, eliminated references to the Hobby Very High Frequency Omnidirectional Range/Distance Measuring Equipment (VOR/DME) as the point of origin and made the new point of origin the current geographical location of the Hobby VOR.
The Houston terminal area has experienced a significant growth in aircraft operations in the last 10 years. To accommodate this growth, the City of Houston is scheduled to complete construction of the new Runway 8L/26R for IAH in October 2003. Additionally, the flow of aircraft operations at HOU will be adjusted to use Runway 4 as the primary runway. To provide protection for operations to the new runway at IAH and the planned traffic flow adjustments at HOU, the FAA has developed the proposed modifications to the Houston Class B airspace area.
Public Input
In June 2002, an ad hoc committee was formed to provide comments and recommendations regarding the planned modifications to the Houston Class B airspace area. Details were provided to the ad hoc committee regarding planned airspace changes required to conduct triple simultaneous approaches to IAH using the new Runway 8L/26R and the need to adjust the flow of aircraft operations at HOU. The Aircraft Owners and Pilots Association (AOPA) participated in the ad hoc committee and suggested developing visual flight rule (VFR) flyways to help pilots transition the Houston terminal area while remaining clear of the Houston Class B airspace area. Additionally, AOPA suggested the FAA solicit input from representatives from the military, Weiser Airpark, and West Houston Airport. These groups and numerous other user groups were contacted for their input and the suggestion to include VFR flyways was incorporated into a presentation for public meetings. Additionally, AOPA's flyway comment will be addressed later in this document.
As announced in the FAA Southwest Region Airspace Branch letter to Airmen 02-02, three pre-NPRM informal airspace meetings were held on October 15 at Fletcher Aviation on HOU; October 16 at North Harris College; and October 22 at West Houston Airport. These meetings allowed interested airspace users an opportunity to present their views and offer suggestions regarding the planned modifications to the Houston Class B airspace area. All comments received during the informal airspace meetings and the subsequent comment period were considered in developing this proposal.
Analysis of Comments Received
Twelve commenters expressed a concern that the planned expansion of Area B and Area C of the Class B airspace area would compress general aviation traffic into lower altitudes, or would cause general aviation aircraft to fly further east or west of IAH to remain clear of the Class B airspace. The FAA partially agrees with these comments. To remain clear of the Houston Class B airspace area, aircraft would have to fly at lower altitudes or fly further east or west of IAH; however, this is necessary to separate them from large turbine-powered aircraft conducting instrument approaches within the Houston Class B airspace area. Aircraft conducting simultaneous, parallel approaches may not be assigned the same altitude during turn-on to the final approach course. Therefore, each aircraft being turned on to the triple, simultaneous final approach courses will be assigned altitudes that differ by a minimum of 1,000 feet. In order to accommodate increased aircraft operations, the Houston Class B airspace area must be modified to provide additional altitudes in the lower stratum to the east and west of IAH.
Six commenters stated that aircraft from satellite airports west of Houston would have to travel significantly further than they presently do to get to practice areas. The FAA does not agree with these commenters. The FAA estimates that these aircraft would only have to fly approximately five additional nautical miles (NM) to remain clear of the Houston Class B airspace area. The planned modifications should not significantly increase the cost to pilots who wish to conduct practice maneuvers clear of the planned areas of the Houston Class B airspace area.
Four commenters stated that the FAA should use additional prominent landmarks instead of radials to describe the boundaries of the Class B airspace area. Specifically, it was suggested that the west boundary of Area C (southwest of HOU) could be described by using Highway 59 instead of radials and DME's from the Point Of Origin at HOU. This suggestion would increase the size of the Houston Class B airspace area approximately three NM and overlie the Sugar Land Airport Class D airspace area to the southeast. After consideration by FAA and users in the Sugar Land area, it was determined that additional restrictions to users would be created with minimal benefit. Additionally, the availability of prominent landmarks in the Houston Class B airspace area is minimal. Therefore, this suggestion is not being incorporated into the proposal. The current and planned boundary descriptions consist of a combination of prominent landmarks, latitude/longitude coordinates, and radials/arcs from the Humble VORTAC and the Point of Origin. The FAA believes that this mix of descriptors effectively assists pilots in identifying the lateral boundaries of the Houston Class B airspace area.
One commenter recommended that the FAA establish a VFR corridor directly above IAH to aid VFR aircraft transiting the Houston area. The FAA does not agree with the recommendation to establish a VFR corridor. The establishment of a corridor would reduce the efficiency of managing aircraft operations in the Houston Class B airspace area. The airspace over and between IAH and HOU is the busiest area due to aircraft departing and arriving IAH and HOU. Adding additional complexity to this area would not be in the best interest of safety or management of aircraft operations.
One commenter suggested developing north-south VFR flyways to the east and west of IAH to help pilots transition the Houston terminal area while remaining clear of the Houston Class B airspace area. Since the inception of the Houston Class B airspace area, several low altitude VFR transition routes have been published on the reverse side of the Houston VFR terminal area chart to assist pilots.
Four commenters expressed concern with the planned VFR flyway west of the airport because the area is already heavily traveled by VFR aircraft arriving and departing the busy west satellite airports. These commenters felt that the flyway would encourage pilots to fly in an already congested area and would not enhance safety or expedite travel. The FAA has withdrawn its plan for a north-south VFR flyway to the west of IAH. If the proposed modifications are implemented, most of the existing flyways remain the same except for adjustments to the suggested altitudes in Area C and Area D, to the east and west of IAH.
Notwithstanding the proposed modifications in this notice, we will continue to work with affected users to develop new and/or modify current flyways to assist in navigating in this busy terminal area.
The Proposal
The FAA is proposing an amendment to part 71 of the Federal Aviation Regulations (14 CFR part 71) to modify the Houston Class B airspace area. Specifically, this action (depicted in the attached chart) proposes to expand the lateral limits of Area A to the east of IAH; expand the lateral limits of Area B to the east and west of IAH; expand the lateral limits of Area C to the east and west of IAH and to the southwest of HOU; and expand the lateral limits of Area D to the southwest of HOU to improve the containment of turbo-jet aircraft operating within the Houston Class B airspace area.
Area A. The FAA proposes to modify Area A by expanding the boundary of Area A to the northeast of IAH. This modification would incorporate into Area A, one segment of the Class B airspace that is currently contained within Area B. Specifically, to the northeast of IAH, the FAA proposes to extend Area A to the north incorporating that part of Area B airspace that lies to the east on the extended instrument landing system (ILS) localizer course for Runway 26R, between the IAH 8 and 10 NM arcs. The effect of extending Area A as described would be to lower the floor of the Class B airspace in the affected segment from the current 2,000 feet mean sea level (MSL) to the surface. The reason for this change is to provide additional airspace needed to ensure that aircraft on the ILS approach to Runway 26R are contained within the Houston Class B airspace area.
Area B. The FAA proposes to modify Area B to the east and west of IAH. This modification would incorporate into Area B, two segments of the Class B airspace that are currently contained within Area C. Specifically, to the east of IAH, the FAA proposes to extend Area B to the east incorporating that part of Area C airspace that lies to the east on the extended ILS localizer course and downwind legs for Runway 26R, 26L, and 27, between the IAH 15 and 20 NM arcs. To the west of IAH, the FAA proposes to extend Area B to the west incorporating that part of Area C airspace that lies west on the extended ILS localizer course and downwind legs for Runway 8L, 8R, and 9, between the IAH 15 and 20 NM arcs. The effect of extending Area B as described would be to lower the floor of the Class B airspace in the affected segments from the current 3,000 feet MSL to 2,000 feet MSL. The reason for this change is to provide additional airspace needed to ensure that aircraft vectored for triple, simultaneous ILS approaches (with the required 1,000 feet vertical separation between aircraft) remain within the Houston Class B airspace area.
Area C. The FAA proposes to modify Area C to the east and west of IAH. This modification would incorporate into Area C, two segments of the Class B airspace that are currently contained within Area D. Specifically, to the east of IAH, the FAA proposes to extend Area C to the east incorporating that part of Area D airspace that lies to the east on the extended ILS localizer course and downwind legs for Runway 26R, 26L, and 27, between the IAH 20 and 30 NM arcs. To the west of IAH, the FAA proposes to extend Area C to the west incorporating that part of Area D airspace that lies to the west on the extended ILS localizer course and downwind legs for Runway 8L, 8R, and 9, between the IAH 20 and 30 NM arcs of the airport. The effect of extending Area C as described would be to lower the floor of the Class B airspace in the affected segments from the current 4,000 feet MSL to 3,000 feet MSL. The reason for this change is to provide additional airspace needed to ensure that aircraft vectored for triple, simultaneous ILS approaches (with the required 1,000 feet vertical separation between aircraft) remain within the Houston Class B airspace area. The FAA also proposes to modify Area C to the southwest of HOU by incorporating into Area C, one segment of the Class B airspace that is currently contained within Area D. Specifically, to the southwest of HOU, the FAA proposes to extend Area C to the southwest incorporating that part of Area D airspace that lies to the southwest on the extended ILS localizer course and downwind legs for Runway 4, between the IAH 15 and 20 NM arcs. The effect of extending Area C as described would be to lower the floor of the Class B airspace in the affected segment from the current 4,000 feet MSL to 3,000 feet MSL. The reason for this change is to provide additional airspace needed to ensure that aircraft vectored for the ILS Runway 4 approach remain within the Houston Class B airspace area.
Area D. The FAA proposes to modify Area D by expanding the boundaries of Area D to the southwest of HOU. This modification would add a segment to the Class B airspace. Specifically, the FAA proposes to extend Area D to the southwest of HOU incorporating airspace that lies to the southwest on the extended ILS localizer course and downwind legs for Runway 4, between the IAH 20 and 25 NM arcs. The effect of extending Area D as described would be to add a segment to the Class B airspace from 4,000 feet MSL to 10,000 feet MSL. The reason for this change is to provide additional airspace needed to ensure that aircraft vectored for the ILS Runway 4 approach remain within the Houston Class B airspace area.
Area E. The FAA is not proposing any changes to the lateral dimensions of Area E.
These modifications would improve the management of aircraft operations in the Houston terminal area, and enhance safety by extending and lowering the floor of Class B airspace to protect a high volume of instrument approaches to IAH and HOU airports. Additionally, this proposed action supports various efforts to enhance the efficiency and capacity of the National Airspace System including the National Airspace Redesign project and the FAA's Operational Evolution Plan.
The coordinates for this airspace docket are based on North American Datum 83. Class B airspace areas are published in paragraph 3000 of FAA Order 7400.9K, Airspace Designations and reporting Points, dated August 30, 2002, and effective September 16, 2002, which is incorporated by reference in 14 CFR section 71.1. The Class B airspace area listed in this document would be published subsequently in the Order.
Regulatory Evaluation Summary
Changes to Federal Regulations must undergo several economic analyses. First, Executive Order 12866 directs that each Federal agency shall propose or adopt a regulation only upon a reasoned determination that the benefits of the intended regulation justify its costs. Second, the Regulatory Flexibility Act requires agencies to analyze the economic effect of regulatory changes on small businesses and other small entities. Third, the Office of Management and Budget directs agencies to assess the effect of regulatory changes on international trade. In conducting these analyses, the FAA has determined that this proposed rule: (1) Would generate benefits that justify its circumnavigation costs and is not a “significant regulatory action” as defined in the Executive Order; (2) is not significant as defined in the Department of Transportation's Regulatory Policies and Procedures; (3) would not have a significant impact on a substantial number of small entities; (4) would not constitute a barrier to international trade; and (5) would not contain any Federal intergovernmental or private sector mandate. These analyses are summarized here in the preamble, and the full Regulatory Evaluation is in the docket.
This NPRM would modify the Houston, TX, Class B airspace. The proposed rule would reconfigure the subarea boundaries, raise the altitude ceiling in certain segments of the airspace and lower the altitude floor in certain segments.
The NPRM would generate benefits for system users and the FAA in the form of enhanced operational efficiency and simplified navigation in the Houston terminal area. These modifications would impose some costs (an additional 5 NM circumnavigation around the expanded controlled airspace) on operators of non-compliant aircraft. However, the cost of circumnavigation is considered to be small. Thus, the FAA has determined this proposed rule would be cost-beneficial.
Initial Regulatory Flexibility Determination
The Regulatory Flexibility Act of 1980 establishes “as a principle of regulatory issuance that agencies shall endeavor, consistent with the objective of the rule and of applicable statutes, to fit regulatory and informational requirements to the scale of the business, organizations, and governmental jurisdictions subject to regulation.” To achieve that principal, the Act requires agencies to solicit and consider flexible regulatory proposals and to explain the rationale for their actions. The Act covers a wide-range of small entities, including small businesses, not-for-profit organizations and small governmental jurisdictions.
Agencies must perform a review to determine whether a proposed or final rule will have a significant economic impact on a substantial number of small entities. If the determination is that it will, the agency must prepare a regulatory flexibility analysis (RFA) as described in the Act.
However, if an agency determines that a proposed or final rule is not expected to have a significant economic impact on a substantial number of small entities, section 605(b) of the 1980 Act provides that the head of the agency may so certify and an RFA is not required. The certification must include a statement providing the factual basis for this determination, and the reasoning should be clear.
This proposed rule may impose some circumnavigation costs on individuals operating in the Houston terminal area; but the proposed rule would not impose any costs on small business entities. Operators of GA aircraft are considered individuals, not small business entities and are not included when performing a regulatory flexibility analysis. Flight schools are considered small business entities. However, the FAA assumes that they provide instruction in aircraft equipped to navigate in Class B airspace given they currently provide instruction in the Houston terminal area. Therefore, these small entities should not incur any additional costs as a result of the proposed rule. Accordingly, pursuant to the Regulatory Flexibility Act, 5 U.S.C. 605(b), the Federal Aviation Administration certifies this rule would not have a significant economic impact on a substantial number of small entities. The FAA solicits comments from affected entities with respect to this finding and determination.
International Trade Impact Assessment
The Trade Agreement Act of 1979 prohibits Federal agencies from engaging in any standards or related activities that create unnecessary obstacles to the foreign commerce of the United States. Legitimate domestic objectives, such as safety, are not considered unnecessary obstacles. The statute also requires consideration of international standards and where appropriate, that they be the basis for U.S. standards.
The proposed rule is not expected to affect trade opportunities for U.S. firms doing business overseas or for foreign firms doing business in the United States.
Unfunded Mandates Assessment
Title II of the Unfunded Mandates Reform Act of 1995 (the Act), enacted as Public Law 0104-4 on March 22, 1995, requires each Federal agency, to the extent permitted by law, to prepare a written assessment of the effects of any Federal mandate in a proposed or final agency rule that may result in the expenditure of $100 million or more (when adjusted annually for inflation) in any one year by State, local, and tribal governments in the aggregate, or by the private sector. Section 204(a) of the Act, 2 U.S.C. 1534(a), requires the Federal agency to develop an effective process to permit timely input by elected officers (or their designees) of State, local, and tribal governments on a proposed “significant intergovernmental mandate.” A “significant intergovernmental mandate” under the Act is any provision in a Federal agency regulation that would impose an enforceable duty upon State, local, and tribal governments in the aggregate of $100 million (adjusted annually for inflation) in any one year. Section 203 of the Act, 2 U.S.C. 1533, which supplements section 204(a), provides that, before establishing any regulatory requirements that might significantly or uniquely affect small governments, the agency shall have developed a plan, which, among other things, must provide for notice to potentially affected small governments, if any, and for a meaningful and timely opportunity for these small governments to provide input in the development of regulatory proposals.
This proposed rule does not contain any Federal intergovernmental or private sector mandates. Therefore, the requirements of Title II of the Unfunded Mandates Reform Act of 1995 do not apply.
Paperwork Reduction Act
In accordance with the Paperwork Reduction Act of 1980 (Pub. L. 96-511), there are no requirements for information collection associated with this proposed rule.
Conclusion
In view of the minimal or zero cost of compliance of the proposed rule and the enhancements to operational efficiency that do not reduce aviation safety, the FAA has determined that the proposed rule would be cost-beneficial.
