Hello,

If you do not want to select any other preference besides Air Force Academy then you may fill '0' for the rest of your preferences. If you do so you will not be considered for admission to other academies such as Indian Military Academy and Naval Academy if you clear written test, SSB interview and Medical Examination. So we would suggest you to give preference in the order of your choice to all academies (highest preference to Air Force Academy). If you do not have required cut off score for Air Force Academy you might still have chances to get admission in to IMA or INA based on your score. But if you do not wish to join in IMA or INA then you may prefer AFA only.
