Oral Communication
  • Discuss operational and administrative matters with co-workers. For example, tower controllers may discuss how much to adjust separation distances between aircraft and whether to close runways during worsening weather conditions. Flight dispatchers may clarify the meaning of particular equipment codes with head pilots in their organizations. Flight service specialists may brief incoming co-workers about runway conditions and incoming flights. (2)
  • Train and give directions to junior co-workers. For example, air traffic controllers may coach new controllers on how to communicate with pilots and other personnel more precisely to ensure clarity and brevity. They may help trainees recover their composure after errors and emergency situations. (2)
  • Speak with airport personnel to coordinate ground traffic control and exchange information. For example, speak to maintenance crews to coordinate the access of vehicles such as snow ploughs to runways. Talk to airport managers to transmit relevant information during emergencies and situations requiring airport closures. (Air Traffic Controllers and Flight Service Specialists) (2)
  • Inform supervisors about heavy traffic, pilot errors, bad weather and any unusual situations for which guidance and assistance are needed. For example, area controllers inform their supervisors when they reroute aircraft to other sectors to limit traffic in their own. (2)
  • Listen to radio exchanges between aircraft and air traffic controllers to obtain information about aircraft arrivals. Air traffic controllers in smaller control centres may monitor continuous airport terminal broadcasts to learn about weather and runway conditions at nearby larger airports. (2)
  • Speak to pilots to provide advisories and instructions. For example, tower controllers and flight service specialists advise all pilots on incoming aircraft of adverse runway conditions. They also communicate with them prior to takeoff, listening as pilots provide aircraft types, identification numbers, destinations and estimated arrival times. In turn, they give winds, altimeter readings and taxiing instructions. Area controllers may direct pilots to change altitudes to maintain safe distances from other aircraft. Flight service specialists advise flight crews of relevant weather conditions. All air traffic controllers and those in related occupations communicate with pilots according to precise protocols and regularly use abbreviations and codes. (3)
  • Exchange information with co-workers and colleagues in order to coordinate traffic control. For example, alert them to unusual situations of aircraft such as medical emergencies and equipment failures. Exchange requests and permissions to redistribute air traffic as required. Area controllers speak to colleagues in other sectors when they hand over responsibility for aircraft, providing essential information such as identifications, speeds and altitudes. Tower controllers speak to ground controllers to coordinate usage of runways. Flight dispatchers may request priority for specific flights from flow controllers in central control offices. (3)
  • Coordinate instructions to pilots, co-workers, supervisors and first responders during emergencies. Respond calmly to emergency calls from pilots and request information to determine the nature of the problems. Inform pilots how to proceed while alerting emergency services to be on hand as needed. Flight dispatchers also coordinate telephone communications between emergency services and cockpit crews, as needed. (4)

Money Math
  • Calculate claim amounts for travel to training sessions and isolated work locations. To calculate total travel expenses, multiply distances travelled in personal vehicles by per kilometre rates and add amounts for meals, hotels and incidentals. (2)
Back to Top

Scheduling or Budgeting and Accounting
  • Prepare work schedules for work units. Prepare work schedules, taking into account twenty four hour a day staffing requirements, variations in volume of air traffic, rotation of night and weekend shifts and pertinent clauses in labour-management contract. For example, air traffic controllers may prepare work schedules which honour contract agreements such as minimum time off between shifts and maximum working hours per week. (3)
  • Calculate time intervals and identify precise times to prepare aircraft movement schedules. For example, tower controllers sequence aircraft for landing taking into consideration runway availabilities and aircraft priorities, locations, speeds and required stopping distances. They may need to reorder schedules to adapt to weather conditions and unexpected events. Area controllers sequence aircraft for their passage to subsequent sectors taking into account speeds, altitudes and locations as well as weather conditions and other factors affecting speeds and priorities. (Air Traffic Controllers) (4)
Back to Top

Measurement and Calculation
  • Take precise measurements to describe the weather at airports and airfields. For example, use thermometers, barometers, anemometers and gauges to measure weather data such as air temperature, barometric pressure, wind speed and precipitation. (3)
  • Calculate distances, speeds, times and amounts of fuel. For example, air traffic controllers calculate positions of aircraft in given amounts of time based on speeds and trajectories. They may also calculate at what time two airplanes would meet given current positions and speeds. Flight dispatchers calculate how much fuel to add to an aircraft given current and required amounts. (3)
Back to Top

Data Analysis
  • Verify data in documents with observations, counts and estimates. For example, tower controllers compare the numbers of aircraft they see from air control towers with expected numbers according to flight progress strips and radar screens to ensure that all aircraft are accounted for. (1)
  • Collect and analyze data on air traffic, fuel consumption, weather and runway conditions. For example, military air traffic controllers may tabulate data about air traffic at airports such as the numbers and types of aircraft and the types of operations per day, month and year. Area controllers may collect data on numbers of aircraft controlled in their sectors per month and per worker, and calculate averages such as aircraft controlled per day. Flight dispatchers analyze differential fuel requirements for alternate flight routes. Flight service specialists collect daily weather data including air temperatures, barometric pressures, wind speeds and amounts of precipitation. They calculate average daytime temperatures. (3)

Numerical Estimation
  • Estimate time and intervals. For example, estimate the number of minutes of delay for departures and arrivals of aircraft given weather conditions, winds and traffic volumes. Estimate the expected arrival times for weather systems taking into account weather bulletins and your own observations. (2)
  • Estimate distances, angles, trajectories and positions. Take into consideration data such as aircraft bearings, and speeds, and wind directions and speeds. For example, air traffic controllers estimate the approximate shift in flight angles needed for two aircraft to maintain minimum separation distances. Tower controllers estimate available distances between aircraft on approach to allow others to land. (Air Traffic Controllers and Flight Service Specialists) (4)

Job Task Planning and Organizing
  • Air traffic controllers and those in related occupations respond to the often complex demands of air traffic. They need to respond quickly to requests, sequence tasks effectively and change priorities when necessary. In periods of high traffic volume, air traffic controllers may answer three or four requests in rapid succession. When traffic levels are low they organize and attend to secondary duties such as evaluating trainees and reading reports. Air traffic controllers and those in related occupations may plan and organize shift schedules and breaks for their work units. (2)
Back to Top

Decision Making
  • Select routes, altitudes and speeds for aircraft flight plans. Take into consideration fuel requirements, weather, prevailing winds, traffic flows and crew work schedules to develop cost-effective flights and ensure timely arrivals. Make adjustments to flight plans to manage delays and unusual circumstances such as severe weather and airport closures. (Flight Dispatchers) (2)
  • Set conditions for access to airspaces, runways and taxiways. Consider factors such as weather conditions, maintenance crews' activities and the needs of air traffic. For example, during high winds tower controllers may choose to use only runways which run in the direction of the wind. They choose times for runway maintenance tasks such as snow clearing and friction tests. Area controllers may permit more direct routes and redirect aircraft around airspaces temporarily closed. (Air Traffic Controllers and Flight Service Specialists) (3)
  • Set the order, times, distances between aircraft and runways to be used for arrivals and departures. Take into consideration weather, runway conditions and availabilities, flight plans, traffic and air traffic regulations. Impose changes to the scheduled order of aircraft to deal with emergencies and other incidents. For example, decide to delay or reorder departures so that smaller aircraft can avoid turbulence caused by larger planes. In some cases, cancel departure authorization for pilots who take too long to prepare. (Air Traffic Controllers) (3)

Problem Solving
  • It may be difficult to communicate with pilots whose command of the English language is limited. Simplify instructions as much as possible to help pilots understand and ask them to repeat back instructions more than once to ensure comprehension. (Air Traffic Controllers and Flight Service Specialists) (1)
  • Experience loss of communications and data. For example, tower controllers may lose radio contact with pilots because of power outages. They use battery-operated light guns to direct pilots to safe landings, monitoring the pilots to ensure they are able to follow the signals. Area controllers may lose data on radar screen displays. They contact data systems coordinators to request repairs to their equipment and they switch to backup units. (2)
  • Accidents, incidents and bad weather complicate arrivals and departures and occasionally close airports. For example, when pilots flying with visual flight rules lose visibility in cloud cover, tower controllers may direct the pilots to set courses for directional lights to help them land safely. They may also monitor the aircraft movements on radar equipment to ensure the pilots stay on course. When winds make particular runways unsafe for aircraft, they coordinate traffic with other controllers to make alternate runways available for landing. Flight dispatchers may need to find alternate airports for their flights in cases of airport curfews and closures and in-flight emergencies. (2)
  • Encounter periods during which the airspace become saturated. Coordinate with controllers in other sectors and airports to pass off some aircraft. In some cases, ask pilots to fly in holding patterns and redirect them to other sectors to alleviate the saturation. (Air Traffic Controllers and Flight Service Specialists) (3)
  • There are uncontrolled aircraft, off-course balloons and other hazards in the airspace. For example, air traffic controllers may spot small airplanes moving into airport airspaces and realize the pilots have not made contact with tower controls. They may try unsuccessfully to communicate with the aircraft and conclude the pilots do not have the proper radio frequencies. They may monitor the pilots' movements while warning all other aircraft in the area as well as airport ground crews. (Air Traffic Controllers and Flight Service Specialists) (3)

Finding Information
  • Find information about airports by visiting airport websites and reading flight supplement manuals. Find information such as distances and flight times, weather conditions, curfews, control tower radio frequencies and official notices of restrictions for airports all over the world. (Flight Dispatchers) (2)
  • Find information on weather and runway conditions by searching Environment Canada weather bulletins, scanning meteorological maps, reading runway surface reports, observing instrument displays, analyzing tephigrams and talking to pilots. Speak to co-workers, air flight specialists and workers in airports to complete knowledge of local conditions. Flight service specialists take daily readings of weather conditions at airports. (2)
  • Find information about the geography, temperature and precipitation patterns of new locations by studying weather tables, maps and satellite images. Military air traffic controllers may also consult with meteorologists to learn about weather conditions as part of their planning for air traffic control centres in new locations. (3)
Back to Top

Critical Thinking
  • Evaluate the performance and competence of trainees in key aspects of the job such as communication skills, spatial logic, ability to stay calm under pressure and knowledge of regulations. Gather data on errors they repeat and the regulations they breach. (Air traffic controllers and related occupations) (2)
  • Evaluate the suitability of computer-generated flight plans. Consider proposed routes, altitudes and speeds. Weigh factors such as weather conditions, jet streams, pilots' opinions and unusual circumstances such as temporary closures of airspaces. (Flight dispatchers) (3)
  • Evaluate the safety of air traffic. Consider the capacity of the air traffic control teams on duty to manage traffic volumes. Flight service specialists and air traffic controllers at airports evaluate the safety of runways using data on conditions such as wind and precipitation and reports from ground crews and pilots. Flight dispatchers evaluate the safety of alternate airports for emergency landings using criteria such as flying distances, presence of mountains and other obstacles, weather conditions and lengths of runways. (Air traffic controllers and related occupations) (3)
  • Evaluate the severity of in-flight emergencies. Take into account the nature of the situations, types of aircraft involved, numbers of passengers, amounts of fuel and presence of dangerous cargoes. Consider whether only on-site emergency crews are required or whether additional crews and equipment should be requested from municipal authorities. (Air traffic controllers and related occupations) (3)
  • Assess the severity of current and developing weather conditions and the level of risk they pose for aircraft you are monitoring. For example, judge the safety of allowing aircraft to fly through severe turbulence and thunderstorms where there will be high wind speeds and lightning strikes. Flight service specialists may evaluate storms as sufficiently severe to warrant closing their airports. (Air traffic controllers and related occupations) (3)
