    Analysis of air traffic capacity in Nigrian airports
    (KY, 2017) Ejem, E. A.; Ibe, C. C.; Dike, D. N.; Chikwendu, D. U.; Igboanusi, C. C.; Chukwu, O. E.
    The paper is aimed at determining the capability of the airside facilities to accommodate aviation operational demand. The USA FAA methodology was utilized for the measurement of airfield capacity in this study. In consideration of the existing runway configuration, runway utilization patterns and 52506 operation counts, Lagos airport domestic wing Nigeria has been determined to have a daily demand ratio (D) of 240 operations and an hourly demand ratio (H) of 20 operations, and thus, an ASV of approximately 63006 operations. Capacity calculations indicated that a Nigerian runway configuration accommodates an ASV of 247, 123 annual operations. Based on the aircraft fleet mix currently utilizing Nigerian airports, this ASV seems appropriate through the planning period. The ASV during the period under study was highest at the domestic wing of Lagos Airport followed International wing of the same airport. Abuja domestic wing was next followed by Port Harcourt domestic wing. It is considered, therefore, that no significant increase to existing peak-hour runway capacity may be possible in the short term although there is spare capacity during the off-peak (shoulder) periods. Nigeria has, in theory, the option of having two additional runways available, to enhance the overall runway capacity of the airport. In practical terms, simultaneous operational use of these runways is unlikely to provide significant and consistent capacity benefits.

    Evaluation of airline service quality attributes: The Nigerian experience
    (U. P., 2017-12) Ejem, E. A.; Dike, D. N.; Igboanusi, C. C.; Ezenwa, A.; Erumaka, O.; Chukwu, O. E.
    Airlines are suffering from such competition. Service quality is typically defined regarding consumer satisfaction. The purpose of this paper is to provide a better understanding of how satisfaction level among passenger with Arik and Aero Airlines is and how its managers can improve their service quality. To reach to achieve this purpose, we have studied different models of service quality measurement and adopted Gronroos model as a comprehensive model, we developed and adopted it to encompass various aspects of airlines’ services. We inclusively inferred that passengers of Arik and Aero are not satisfied with the perceived services and it warns manager to focus on passengers’ expectations. Tangibles, assurance, responsiveness, reliability, empathy, image and technical quality are seven features of the model, and in all of them, passengers feel dissatisfied. Managers should treat employees, improve visual facilities and coordinate all people, departments, and organizations involved with the airline. Finally, with airline must measure passengers’ satisfaction and service quality seasonally to keep the services corresponded with customers’ opinions.
