As of the specified date (01.12.2015), the Commissioner of the Bureau of Civil Aviation Security (BCAS) was generally not included in the list of persons exempted from pre-embarkation security checks at civilian airports, unlike the other dignitaries listed.
Exemption from security checks is typically granted to very high constitutional functionaries, specific protectees (like SPG protectees), holders of high national honours, and certain security personnel *when on duty* and identified.
The list of exempted persons is periodically updated by the Ministry of Civil Aviation based on security protocols and official status. While Bharat Ratna awardees, His Holiness the Dalai Lama (due to his status and security needs), and Chiefs of Staff (ranking as full General or equivalent) were typically on the exempted list as of 2015, the Commissioner of BCAS, despite their crucial role in aviation security, was not usually on this specific personal exemption list for the physical security check.
