  1. 1The Portuguese ANSP wants to have a quick estimation of the capacity of its network for the forecast traffic of 2025. Which technique is more suitable for the task?
    1. AJudgment analysis, because it is faster and has a global scope
    2. BFast time simulations, because it will not require the implication of air traffic controllers
    3. CReal time simulations, because it is faster than the other techniques for network analysis
    4. DReal time simulations, because it’s more accurate
  2. 2In the United States, when there is a lack of capacity at a given airport and the capacity cannot be accommodated, a ground delay program (GDP) is defined because:
    1. AThe time the passengers are in the air is maximized
    2. BGround delay are preferred over air delay only due to their lower cost
    3. CAir delay are preferred because they are a better approach to deal with capacity-demand imbalances in order to maximize the throughput of the airport
    4. DBy doing ground delay, the workload of the controllers at the TMAs is reduced
  3. 3Assuming that the AAR at a given airport is known. Being t the time when the GDP is defined (file time), as t increases, the number of affected flights (controlled flights):
    1. AIncreases, dividing the delay between more planes
    2. BRemains constant. Therefore, it is better to define the GDP as late as possible to reduce the uncertainty
    3. CDecreases, therefore the average delay per delayed aircraft increases
    4. DDecreases, therefore the total delay assigned is reduced
  4. 4In the genetic algorithm optimization technique, the linear transformation of the objective function prior to the fitness function:
    1. AReduces the probabilities of a quick convergence, and therefore, maximizes the possibilities of finding a global optima
    2. BIt is a method to transform a multi-objective problem into a single-objective problem
    3. CIt is only used when instead of a minimization the algorithm is used to maximize the problem
    4. DEnsures there are not negative values but can lead to a quick convergence
  5. 5An airport has a capacity that is lower than its demand. In order to minimize the amount of ground delay assigned to the aircraft, a RBS algorithm is used. The same problem is solved by using integer programming (IP).
    1. ABoth solutions will minimize the amount of total delay assigned (same amount of delay) but the solution computed with IP will be fairer
    2. BIP will probably assign less total delay than RBS, and therefore IP is preferable
    3. CRBS will have the same amount of total delay as IP
    4. DRBS will probably assign less total delay than IP, and therefore RBS is preferable
  6. 6An airport has a capacity that is lower than its demand. In order to minimize the amount of ground delay assigned to the aircraft, a RBS algorithm is used. The same problem is solved using IP, for example using a GHP formulation.
    1. ABoth solutions will minimize the amount of total delay assigned (same amount of delay) but the solution is not guaranteed to be feasible
    2. BIP will probably assign less total delay than RBS, and therefore IP is preferable
    3. CRBS will have the same amount of total delay as IP
    4. DRBS will probably assign less total delay than IP, and therefore RBS is preferable
  7. 7For a given airspace (i.e. a FIR):
    1. AThe number of sectors changes dynamically as a function of the demand according to the Opening Scheme
    2. BReal-time simulations are used to determine the best sector configuration (opening scheme) for the next hours of operations
    3. CThe convexity constraint when constructing a new sectorization ensures that a flight will be a minimum amount of time in the sector
    4. DThe genetic algorithms are the only technique used to generate the best sectorization for the airspace
  8. 8With the introduction of Free Routes and User-preferred routings:
    1. AThe capacity of the airspace increases because the traffic is less structured
    2. BThe ANSP suggest to the airlines direct routes between the published waypoints
    3. CA higher interoperability between actors is required
    4. DIt is only possible in oceanic tracks
  9. 9With the introduction of Free Routes and User-preferred routings:
    1. AThe capacity of the airspace may increase because the probability of having conflicts has been found to be lower (traffic is less structured)
    2. BThe ANSP suggests to the airlines direct routes between the published waypoints
    3. CThe Airspace Users are not required to file a flight plan
    4. DIt is only possible in oceanic tracks
  10. 10The factors that affect the en-route capacity of the airspace are:
    1. ASpatial-Geometrical factors (such as the training of the ATC), the controllability (such as the work of the pilot), and the capacity resilience.
    2. BSpatial-Geometrical factors (such as the airspace configuration), the controllability (such as the work of the pilot), and the capacity resilience.
    3. CSpatial-Geometrical factors (such as the training of the ATC), the controllability (such as the flow management), and the capacity resilience.
    4. DNone of the previous answers.
