Air Traffic Control Series, 2152

Individual Occupational Requirements

Experience And Education Requirements

Applicants may meet minimum qualification requirements on the basis of experience, education, or, for GS-7 positions, one of the alternate provisions described below.

Experience

General Experience (for GS-4 and GS-5):

Progressively responsible experience that demonstrated the potential for learning and performing air traffic control work. Two years of such experience is required for GS-4 positions, and 3 years is required for GS-5 positions.

Specialized Experience (for GS-7 and above):

Experience in a military or civilian air traffic facility that demonstrated possession of the knowledge, skills, and abilities required to perform the level of work of the specialization for which application is made. This experience must have provided a comprehensive knowledge of appropriate air traffic control laws, rules, and regulations.

Examples of specialized experience include:

For Station Positions: Providing information to pilots on such matters as weather, air routes, navigational aids, and airport conditions before and during flight. This specialization also requires:

• Judgment to select only essential and pertinent information from a great mass of data;
• Skill to present essential information to pilots clearly, concisely, and quickly before or during flight; and
• Ability to act decisively in emergency situations.

For Terminal Positions: Issuing control instructions and advice to pilots in the vicinity of airports to assure proper separation of aircraft and to expedite their safe and efficient movement. This specialization also requires:

• Ability to act decisively under stressful situations and to maintain alertness over sustained periods of pressure;
• Skill to coordinate plans and actions with pilots and other controllers; and
• Judgment to select and take the safest and most effective course of action from among several available choices.

For Center Positions: Controlling aircraft operating enroute along the airways to assure proper separation and safe and expeditious movement of such aircraft. This specialization also requires:

• Skill to control aircraft operating at very high speeds over great distances;
• Skill to arrange air traffic in patterns that assure maximum safety and minimum delay at points where such aircraft are "handed off" or transferred to other facilities or other sectors within the center; and
• Judgment to estimate when and where traffic congestion will build to a point that necessitates changing patterns, and to plan accordingly.

For Research and Development Positions: Experience in a terminal, station, or center that demonstrated the ability or potential to:

• Create, design, and/or develop new air traffic control systems or concepts; and
• Analyze, test, and evaluate current or new air traffic control procedures, methods, systems, or concepts.

For Combination Positions: Positions involving a combination of the duties of two or more specializations require that applicants meet the qualification requirements for the appropriate specializations.

Up through GS-7, specialized experience in one specialization is fully qualifying for reassignment or promotion into another specialization. At GS-9 and above, experience and training in one specialization is qualifying for another specialization if the applicant's total background indicates that he or she can gain the knowledge, skills, and abilities required in the new assignment after a reasonable period of orientation and training. All positions at the full performance level of each specialization require skill and training in the work of the specialization.

For all specializations, qualifying specialized experience must have provided the ability to:

• Arrive quickly at well-reasoned solutions to complex problems;
• Adjust quickly to different assignments, changing conditions, and workload fluctuations;
• Remain calm and controlled during and after long periods of tension and fatigue; and
• Speak rapidly, clearly, and distinctly.

Level of Experience: For each grade level, creditable experience must have equipped applicants with the knowledge, skills, and abilities to perform the full range of duties of the position for which application is being made. Such experience is typically demonstrated by accomplishment of assignments of the difficulty and responsibility described in the position classification standard used to evaluate positions at the next lower grade level in the normal line of promotion to the position being filled.

or

Education

For GS-5 Positions: A full 4-year course of study leading to a bachelor's degree meets the requirements for GS-5.

For GS-7 Positions: Superior academic achievement at the baccalaureate level or 1 full year of graduate study meets the requirements for GS-7.

or

ALTERNATE REQUIREMENTS FOR GS-7 POSITIONS

Applicants who pass the written test qualify for GS-7 if they:

• Hold or have held an appropriate facility rating and have actively controlled air traffic in civilian or military air traffic control terminals or centers;
• Hold or have held an FAA certificate as a dispatcher for an air carrier;
• Hold or have held an instrument flight rating;
• Hold or have held an FAA certificate as a navigator or have been fully qualified as a Navigator/Bombardier in the Armed Forces;
• Have 350 hours of flight time as a copilot or higher and hold or have held a private certificate or equivalent Armed Forces rating;
• Have served as a rated Aerospace Defense Command Intercept Director; or
• Meet the requirements for GS-5 and pass the written test with an appropriately higher score.

Maximum Entry Age

Under the provisions of 5 U.S.C. 3307, a maximum entry age has been established for Terminal and Center positions.

Test Requirements

Applicants for competitive appointment and inservice placement to all positions in this series at GS-7 and below must pass a written test. A written test may also be required for positions above GS-7.

Personal Qualities

In addition to meeting all other requirements, applicants must demonstrate possession of the traits and characteristics important in air traffic control work. Applicants who qualify in the written test and/or meet the experience and training requirements will be required to appear for a pre-employment interview to determine whether they possess the personal characteristics necessary for performance of air traffic control work.

Additional Screening Requirements

Applicants who have passed the written test (and the interview, if required) may be required to pass additional air traffic control aptitude screening for positions in the Department of Transportation, Federal Aviation Administration. Persons who do not pass the aptitude evaluation testing requirements will not be appointed to these positions.

Training Requirements

At all trainee and developmental levels, employees must learn the skills needed for operation at higher levels of responsibility. Failure of employees to meet training requirements for or accept promotion to higher grade air traffic control specialist positions may constitute grounds for reassignment, demotion, or separation from employment.

Certificate And Rating Requirements

Air traffic control specialists in all specializations must possess or obtain, within uniformly applicable time limits, the facility ratings required for full performance at the facility where the position is located.

Applicants must possess or obtain a valid Air Traffic Control Specialist Certificate and/or Control Tower Operator Certificate, if appropriate. These certificates require demonstrating knowledge of basic meteorology, basic air navigation, standard air traffic control and communications procedures, the types and uses of air navigation aids, and regulations governing air traffic.

Facility ratings require demonstration of a knowledge of the kind and location of radio aids to air navigation, the terrain, the landmarks, the communications systems and circuits, and the procedures peculiar to the area covered by the facility.

Medical Requirements

In general, air traffic control specialist applicants and employees must have the capacity to perform the essential functions of these positions without risk to themselves or others. The provision of sufficient information about physical capacity for employment requires that before appointment applicants undergo appropriate pre-employment physical/medical evaluations.

The physical impairments/medical conditions that follow, unless otherwise noted, are disqualifying because there are medical and/or management reasons to conclude that an individual with such impairment/condition cannot perform the duties of the position without unacceptable risk to his or her own health, or to the health or safety of others (employees or the public).

Initial Employment:

Applicants for initial employment to air traffic control specialist positions must meet the following requirements. (Unless otherwise indicated, these requirements are identical for all specializations.)

Eye

1. Visual Acuity
   1. Terminal and Center Positions -- Applicants must demonstrate distant and near vision of 20/20 or better (Snellen or equivalent) in each eye separately. If glasses or contact lenses are required, refractive error that exceeds plus or minus 5.50 diopters of spherical equivalent or plus or minus 3.00 diopters of cylinder is disqualifying. The use of orthokeratology or radial keratotomy methods is not acceptable for purposes of meeting this requirement. The use of contact lenses for the correction of near vision only or the use of bifocal contact lenses for the correction of near vision is unacceptable.
   2. Flight Service Station Positions-- Applicants must demonstrate distant and near vision of 20/20 or better (Snellen or equivalent) in at least one eye. If glasses or contact lenses are required, a refractive error in at least one eye that exceeds plus or minus 8.00 diopters of spherical equivalent will necessitate an ophthalmological consultation to establish absence of ocular pathology that could interfere with visual function. The use of contact lenses for the correction of near vision only or the use of bifocal contact lenses for the correction of near vision is unacceptable.

      Equivalents in Near Visual Acuity Notations
      Standard Test Chart: 14/14
      Snellen Metric: 0.50M
      Jaeger: J-1
      Metric: 6/6

2. Color Vision -- For all specializations, applicants must demonstrate normal color vision.
3. Visual Fields
   1. Terminal and Center Positions -- Applicants must demonstrate a normal central visual field, i.e, the field within 30 degrees of the fixation point, in each eye. They must also demonstrate a normal peripheral visual field, i.e., the field of vision beyond the central field that extends 140 degrees in the horizontal meridian and 100 degrees in the vertical meridian, in each eye.
   2. Flight Service Station Positions -- Applicants must demonstrate a normal central field of vision, i.e., the field within 30 degrees of the fixation point, in at least one eye.
4. Intraocular Pressure -- For all specializations, if tonometry reveals either intraocular pressure greater than 20 mm of mercury, or a difference of 5 or more mm of mercury intraocular pressure between the two eyes, ophthalmological consultation is required to rule out the presence of glaucoma. If a diagnosis of glaucoma is made, or if any medication is routinely required for control of intraocular tension, the applicant is disqualified.
5. Phorias
   1. Terminal and Center Positions -- If an applicant demonstrates greater than 1-1/2 prism diopters of hyperphoria or greater than 10 prism diopters of esophoria or exophoria, evaluation by a qualified eye specialist is required. If this evaluation determines that bifoveal fixation and vergence-phoria relationships sufficient to prevent disruption of fusion under normal working conditions are not present, the applicant is disqualified.
   2. Flight Service Station Positions -- Applicants must demonstrate the absence of diplopia in the cardinal fields of gaze.
6. Eye Pathology -- For all specializations, if examination of either eye or adnexa reveals any form of glaucoma or cataract formation, uveitis, or any other acute or chronic pathological condition that would be likely to interfere with proper function or likely to progress to that degree, the applicant is disqualified.
7. Chronic Eye Disease -- For all specializations, an applicant with any chronic disease of either eye that may interfere with visual function is disqualified.
8. Ocular Motility -- For terminal and center specialist positions, applicants must demonstrate full extraocular motility.
9. History of Eye Surgery -- For all specializations, a history of ocular surgery requires ophthalmological consultation. If consultation indicates that the condition that necessitated surgery could interfere with the visual function necessary for performance as an air traffic control specialist, the applicant is disqualified. A history of radial keratotomy is disqualifying.

Ear, Nose, Throat, Mouth

1. Examination must show no outer, middle, or inner ear disease, either acute or chronic, unilateral or bilateral.
2. Examination must show no active disease of either mastoid.
3. Examination must show no unhealed perforation of either eardrum.
