Flight Research and Analysis Group

Flight Systems Laboratory (FSL)

OUR FUNCTION

The Flight Systems Laboratory (FSL) is the research and development arm of the Flight Research and Analysis Group. The FSL assesses the safety associated with the implementation of emerging instrument flight operational concepts and navigational systems into the NAS.

OUR EXPERTISE

The FAA FSL consists of individuals with diverse backgrounds, including:

  • Engineers
  • Mathematicians
  • Operations Research Analysts

OUR CLIENTS

The laboratory’s clients include internal Flight Technologies and Procedures Division stakeholders, air traffic, airports, FAA regions, the aviation industry, and FAA executives who seek objective safety assessments of emerging instrument flight operational concepts and navigation systems to improve flight operations, standards, capacity, and aviation safety within the NAS.

WHAT WE DO

The primary role of the FSL is to perform safety studies, which typically result in the generation of a safety study Technical Report. A safety study is a scientific study of an operational system that is made in order to determine its operational risk. It is scientific in that it uses objective measurement and quantitative analysis to produce its results. The operational system under study consists of scenarios that include potential hazards, and there is risk associated with encountering a hazard within a scenario. The risk must be understood and quantified in order to determine the safety of the system. Steps utilized in the performance of safety studies include:

  • Problem definition,
  • Modeling the problem and developing mathematical models,
  • Data collection and data organization,
  • Data analysis and evaluation of risk, and
  • Reporting results via a Technical Report.

Q&As for Safety-Sensitive Employees

Thursday, September 26, 2024

The following questions are the most common inquiries received by the FAA's Drug Abatement Division from individuals or employees who perform safety-sensitive functions and are subject to Federal drug and alcohol testing in the aviation industry. The questions and responses below aim to bring greater understanding and awareness to the Federal drug and alcohol testing regulations [49 CFR part 40 and 14 CFR part 120].

The following questions are frequently asked by individuals who are being investigated by the FAA Drug Abatement Division, Special Investigations Branch and receive a Letter of Investigation (LOI) regarding a drug/alcohol violation.

If you have any additional questions regarding the DOT/FAA drug and alcohol testing program, please contact the Drug Abatement Division via email at drugabatement@FAA.gov or call (202) 267-8442.

The Department of Transportation's Office of Drug and Alcohol Policy and Compliance has also published a list of Frequently Asked Questions by employees.

Frequently Asked Questions & Hot Topics

Q. What airport characteristics factor into your runway analysis data?
A. Obstacles, slope, elevation, and runway lengths (i.e. TORA, TODA, ASDA, LDA).

Q. Am I really only clearing obstacles in my flight path by 35 feet?
A. No, there is a safety margin built into AFM performance data. This safety margin is outlined in Part 25 (Aircraft Certification), but involves a conservatism applied to the actual data gathered by the test pilots upon certification. This conservatism is accomplished in various forms, with the most commonly referred to being a Gross climb gradient reduced to Net climb gradient factor. This is a reduction in the actual aircraft’s climb performance as a function of the number of engines. The decrement ranges from 0.8% (2 engine aircraft) to 1% (4 engine aircraft) for first, second, and third segment climbs/acceleration. An example would be if you are clearing an obstacle by a NET 35 ft, and the obstacle is 2 NM off of the departure end of the runway, you will actually be clearing that obstacle by at least 135 feet. At 10 NM this becomes over 500 ft. To determine the actual aircraft height above the 35 foot NET height, simply multiply the gradient reduction, .008 for example, by the distance in feet, to the obstacle. Also, this is assuming the worst case scenario of losing the critical engine AT V1, continuing the takeoff, operating at the maximum weight allowed for that scenario, and the obstacle in question is the most limiting obstacle. If the engine failure occurs after V1, or you depart with a lower weight than the maximum for that scenario, you will further increase this safety margin.

Q&As for Safety-Sensitive Employees

Thursday, September 26, 2024

What constitutes a violation of the FAA's drug and alcohol testing regulation?
You have violated the FAA's drug and alcohol testing regulation (14 CFR part 120) if you have:

  • A verified positive result on a drug test;
  • Misused alcohol in any of the following situations:
    • An alcohol test resulting in an alcohol concentration of 0.04 or greater;
    • Used alcohol while on-duty;
    • Used alcohol pre-duty (8 hours prior to duty for a pilot, flight attendant, or air traffic controller; or 4 hours prior to duty for all other employee categories);
    • Used alcohol within 8 hours following an accident.
  • A refusal to submit to required testing

 

Spatial Disorientation and Aerospace Medicine Reference Collection

Friday, September 08, 2023

This site provides information that relates to civilian and military spatial disorientation and aerospace medicine, physiology, and human factors. These files were previously available through a United State Air Force (USAF) Web site hosted by Wright Patterson Air Force Base. The USAF provided the files to the Civil Aerospace Medical Institute (CAMI) so that, combined with CAMI's spatial disorientation and aerospace medicine archives, the information would be available to the public.

The files are presented as were originally organized. We invite readers to contribute material to this archive; please contact the Civil Aerospace Medical Institute.

Current Organization Scheme

 

AIR Transportation Division

The division is also responsible for management and oversight of:

  • Air taxi insurance certification
  • FAA's Aviation Safety and Health Program
  • FAA's Whistleblower Protection Program
  • The National Simulator Program

Specific Functions

  • Advises the Director, the Associate Administrator, and other principal officials, and serves as a point of contact for the aviation community on matters in related program areas which are appropriate to the national level
  • Determines the need for and recommends research and development projects
  • Determines the need for, justifies, and formulates new or amended regulations, supplementary regulatory material and grants or denials of exemption petitions; participates in regulatory review programs; and develops operations specifications
