ATC Clearance
ATC clearance is a formal authorization from Air Traffic Control for aircraft to proceed under specified conditions within controlled airspace, ensuring safety,...
Clearance ensures all obligations are resolved before personnel leave or transfer, covering property, access, medical, and security requirements.
Clearance—Authorization or Physical Separation—is a cornerstone concept in aviation, federal, military, and civilian personnel management. This reference explores its definitions, applications, legal frameworks, and practical procedures, drawing on standards from the International Civil Aviation Organization (ICAO), U.S. government directives, and best practices across sectors.
Personnel Clearance is a regulated process ensuring that individuals have satisfied all organizational obligations—property, access, financial, administrative, medical, and security—before separation, transfer, or change in status. This mitigates risks of information leakage, asset loss, or unauthorized access. Clearance routines are detailed in checklists, such as the U.S. GSA Form 1655 or DA Form 137-2 (Army Out-Processing), and span across government, military, and aviation agencies.
In aviation, ICAO Annex 17 and Doc 9870 stress rigorous clearance for individuals in sensitive roles (e.g., air traffic controllers, airport security, maintenance engineers) to prevent insider threats and ensure infrastructure protection. All clearance steps are documented and retained for audit.
Authorization is the formal approval—documented via forms, electronic systems, or letters—granting or revoking rights to access resources or separate from a role. In aviation, ICAO Annex 1 and 17 require explicit authorization for access to restricted areas or sensitive operations, and for the termination thereof upon separation. Lack of proper authorization can result in regulatory violations or security lapses.
Physical Separation refers to the act of leaving a post or organization, following the completion of all clearance steps. This includes property return, access deactivation, and final debriefs. Aviation standards and government protocols stipulate a “final out-processing” appointment to certify completion of all obligations prior to exit, with incomplete protocols potentially resulting in loss of benefits or operational risks.
Administrative Clearance addresses all non-physical obligations, such as returning credentials, settling debts, deactivating access, and completing required paperwork. In aviation, this is vital for personnel with access to confidential systems or flight operations. Forms like GSA 1655, NIH 2737-2, and DA 137-2 require sign-offs from multiple departments, and their completion is tied to the release of pay or records.
Medical Clearance verifies an individual’s medical fitness for assignment, deployment, or separation, documenting health at exit. For aviation, ICAO Annex 1 governs medical standards for pilots and controllers, necessitating physical exams and record reviews. In the military, forms like DS-1843 and the Separation Health Assessment (SHA/SHPE) document health status for benefits and liability purposes.
During pandemics or health crises, clearance may involve additional screening per ICAO or WHO guidance.
Security Clearance Deactivation is the withdrawal of access to classified information or secure facilities. Mandated by federal and aviation regulations (e.g., ICAO Annex 17, NISPOM), it requires a formal debrief, return of credentials, and documentation of continuing legal obligations. Immediate deactivation is essential, especially for those with airside or critical infrastructure access.
Property Clearance ensures all government or organization-owned items (e.g., uniforms, computers, radios, vehicles) are returned or accounted for. Managed by logistics/property offices, this process is documented in clearance forms, with unresolved issues potentially resulting in pay offsets or legal action. Aviation security manuals (ICAO Doc 8973) underline the importance of property tracking for asset and cyber protection.
SHA/SHPE are medical evaluations required pre-separation for military personnel, documenting health for future benefit claims. Mandated by DoDI 6040.46 and aligned with ICAO standards, they include a self-reported history and clinical evaluation, with results shared with the Department of Veterans Affairs. Aviation personnel may undergo similar assessments to ensure occupational health risks are addressed.
EFMP supports service members with family members requiring special medical or educational care. During separation or transfer, members must complete additional clearance steps for dependents, ensuring ongoing care or proper case closure. Aviation agencies may operate similar programs for remote or overseas assignments.
Separation Transfer describes moving between agencies or out of service, governed by agency and ICAO/CAA regulations. It requires formal personnel actions (e.g., SF-52), fulfillment of all clearance items, and secure transfer of credentials and records. ICAO Doc 9379 outlines best practices for license and record transfers in aviation.
Active Duty (full-time military service) and Service Members face the most rigorous clearance routines due to sensitive access. Military protocols (e.g., Army Regulation 600-8-101, DoDI 6040.46) ensure all obligations are met and post-service responsibilities are understood.
A Transferring Employee must clear property, access, and credentials from the departing post, with new credentials issued by the receiving entity. In aviation, this includes transfer of licenses or badges, regulated by ICAO standards, to prevent unauthorized access or operational disruption.

Incomplete clearance can delay pay, forfeit benefits, result in regulatory action, security breaches, or legal liability for lost property. In aviation, lapses may prompt fines or operational suspensions by CAA or ICAO.
Medical or disability separations, EFMP participation, overseas postings, or sudden terminations may require adapted clearance steps, additional documentation, or immediate action by supervisors to secure property and access.
Q: Who starts the clearance process?
A: The individual, but supervisors and HR ensure all steps are complete.
Q: What if the person is unavailable?
A: Supervisors finalize clearance, document obligations, and notify authorities.
Q: Contractors—same rules?
A: Yes, especially for property, access, and medical/security obligations.
Q: How are medical records handled?
A: Returned to the individual or forwarded to the appropriate agency (e.g., VA).
Q: Security debriefs—why needed?
A: To remind of legal obligations and formally deactivate access.
Clearance—Authorization or Physical Separation—is critical for compliance, security, and operational continuity. Whether in aviation, military, or civil service, comprehensive clearance processes protect assets, information, and people at every transition.
Clearance is the systematic process of verifying all obligations—such as return of property, deactivation of access, and completion of medical/security requirements—are resolved before an individual separates or transfers from an organization, ensuring compliance and security.
The individual leaving typically initiates clearance, but supervisors and HR or administrative officials are responsible for oversight, ensuring all checklist items are completed and documented.
Yes. Contractors must fulfill clearance steps similar to employees, including property return, access deactivation, and, where applicable, medical and security debriefings, especially for sensitive or overseas roles.
Non-compliance can result in delayed pay or benefits, loss of rehire eligibility, regulatory violations, security breaches, and potential legal action for unreturned property or unresolved liabilities.
Clearance is documented through standardized forms and checklists, signed by responsible officials. These records are retained for audit by regulatory bodies, ensuring traceability and accountability.
Ensure regulatory compliance and operational security with robust clearance procedures for personnel separation and transfer. Protect your organization and maintain continuity by implementing best practices in clearance, property return, and access deactivation.
