![]() Please provide a summary description of eliminated alternatives and the reasons for their elimination. If yes, describe any alternatives to the proposed action.ģ.2. Are there alternatives to the proposed action? If not, describe what necessitates this proposed action:ģ.1. ![]() ☐ Community Request ☐ Regulatory Mandate ☐ User RequestĢ.1.2. Is the proposed action the result of a user or community request or regulatory mandate? If detailed background information is available, summarize here and provide a copy as an attachment to this review.Ģ.1.1. The purpose and need for the proposed action must be clearly explained and stated in terms that are understandable to individuals who are not familiar with aviation or commercial aerospace activities. Present the problem being addressed and describe what the FAA is trying to achieve with the proposed action. Describe the purpose and need for the proposed action. Will there be actions involving civil jet aircraft arrival procedures between 3,000-7,000 feet AGL or departures between 3,000-10,000 feet AGL?Ģ.1. What is the lowest altitude on newly proposed routes or on existing routes that will receive an increase in operations?ġ.3.9. Will all changes occur over 3,000 feet above ground level (AGL)?ġ.3.8. If so, what types of aircraft are involved, i.e., general aviation propeller-driven versus large air carrier jets?ġ.3.7. Will there be a change in takeoff power requirements? If the proposed action specifically involves a charted visual approach (CVA) procedure, provide a detailed local map indicating the route of the CVA, along with a discussion of the rationale for how the route was chosen.ġ.3.6. Is the proposed action primarily designed for Visual Flight Rules (VFR), Instrument Flight Rules (IFR) operations, or both? Will airport preferential runway configuration use change as a result of the proposed action?ġ.3.5. local?ġ.3.3.Ěre any noise abatement programs presently in effect for the affected airport(s), formal or informal?ġ.3.4. Will there be actions affecting changes in aircraft flights between the hours of 10 p.m. If yes, provide a summary of the output from the modeling.ġ.3.2. Has airspace modeling been conducted using Sector Design Analysis Tool (SDAT), Aviation Environmental Screening Tool (AEST), Terminal Area Route Generation, Evaluation, and Traffic Simulation (TARGETS), or another airspace/air traffic design tool? Describe anticipated changes to the fleet mix, numbers of aircraft on the new routes and their altitude(s), if any.ġ.3.1. Describe the proposed action, providing the necessary chart(s) depicting changes. Describe the typical fleet mix, including (if possible) the number and types of aircraft on the route (both annually and average day) and depict their altitude(s) along the route.ġ.3. Provide the necessary chart(s) depicting the current procedure(s). Describe the existing procedure(s) (the no action alternative) in full detail. If not quantifiable, describe the approximate anticipated benefits in lay terms.ġ.1.2.ĝescribe any additional operational and/or environmental benefits that may result from the proposed action.ġ.2. If so, can it be quantified, and how?ġ.1.1.b. Is a reduction of fuel cost and/or energy consumption anticipated as a result of the proposed action?ġ.1.1.a. ![]() Describe the operational and/or environmental benefits that may result if the proposed action is implemented.ġ.1.1. Identify the associated airports and/or facilities.ġ.1. Include general information identifying procedure(s) and/or airspace action(s) to be implemented and/or amended. Additional guidance on the identification of potential environmental impacts by environmental category is available in the 1050.1 Desk Reference.ĭescribe the proposed project. If the Instrument Flight Procedure (IFP) Environmental Pre-Screening Filter is used for initiating the environmental review process, and it passes the initial screening, then the IER is unnecessary. Although it requests information in several categories, not all the data may be available initially however, it does represent information, in accordance with FAA Order 1050.1, Environmental Impacts: Policies and Procedures, which ultimately will be needed for preparation of the appropriate environmental document. This IER provides basic information about the proposed action to better assist in preparing for the environmental analysis phase of a proposed action.
