Aerodrome Safeguarding and Aeronautical Charting Specialist focused on obstacle control and PANS OPS/IFP validation

PhilippinesActively looking

I provide aerodrome safeguarding support and aeronautical studies to protect airspace from obstacle penetration, from assessment through charting, reporting, and coordination with relevant stakeholders. My work focuses on obstacle control within defined radii, OLS and height restrictions, and ETOD related data assurance. In Abu Dhabi with GAL ANS, I updated and maintained the accuracy of aeronautical charts from data origin to AIP publication, including obstacle charts, profile and plan view validation for approach procedures, and verification of magnetic variation, bearings, radials, projection, scale, and coverage. I also developed and monitored safeguarding maps for planning authorities and supported contingency development when obstacles were identified as penetrating OLS. I have built strong capability in PANS OPS based procedure and chart preparation, minimum safe altitude calculations, OCA/H and climb gradient evaluations, and quality control for aeronautical and aerodrome data. I also act as a focal point to the regulator regarding significant obstacles published in the UAE AIP, and I provide training on OLS and charting and mapping. Earlier roles included aeronautical surveying and OLS drawing production in AutoCAD, aeronautical survey reporting using WGS 84 and EGM96, and calculations for slopes, penetration, geoidal separation, and collision risk model analysis. I am comfortable working with ICAO and Annex 14 criteria, and I deliver clear technical outputs that support safe and compliant airspace operations.

Experience

P

Aerodrome Safeguarding Consultant

Philippines

Jan 2022 – Jan 2025

Philippines

Assisted the Aerodrome Safety Manager with obstacle control within the required ETOD aeronautical survey radii (45 km from the ARP and 10 km for area 2). Delivered training on Obstacle Limitation Surfaces (approach, take-off climb, transitional, and related surfaces) and provided support for ETOD aeronautical surveys and required aeronautical studies. Also provided training on charting and mapping and supported obstacle-related aeronautical deliverables.

Aerodrome Safeguarding / Charting Specialist

Abu Dhabi International Airport – GAL ANS

Jan 2014 – Nov 2022

Abu Dhabi, UAE

Maintained the accuracy and integrity of aeronautical charts from origin of data through distribution and publication in the AIP. Produced and validated obstacle and procedure-related chart content (including obstacle chart Type A, approach procedure profile/plan views, and distances/altitudes/heights/gradients) while verifying geospatial and publication parameters such as magnetic variation, bearings, radials, projections, and scales. Conducted obstacle assessments against Annex 14 and PANS OPS requirements, calculated minimum safe altitudes and OCA/H with obstacle overflight climb gradients, supported instrument/visual procedure design and approval workflows, and performed QC/QA including ETOD quality control and AIS support for NOTAM processing.

Project Coordinator

Warner Land Surveys

Aug 2012 – Jun 2013

Dubai, UAE

Conducted aeronautical studies for buildings around 150 m above ground level that could affect instrument flight procedures. Produced AutoCAD OLS (Obstacle Limitation Surface) drawings according to AIP requirements and calculated obstacle penetration using defined slope values (1.2%, 1.6%, 2.0%, and 2.5%) from nearest thresholds. Superimposed structure lateral positions onto OLS to determine allowable heights, compiled aeronautical survey reports using WGS 84/EGM96 requirements, and prepared Aircraft Warning Light studies following ICAO norms.

Emirates Nortech Surveys LLC

Sep 2003 – Jun 2012

United Arab Emirates

Prepared OLS-related drawings from aeronautical data in AutoCAD and compiled aeronautical survey reports aligned with aeronautical survey requirements using WGS 84 and EGM96. Calculated slope values and obstacle penetration against ICAO/Annex 14 surfaces (Inner Horizontal, Transitional, Conical, and Horizontal), superimposed structure positions on OLS to determine allowable heights, and supported Aircraft Warning Light assessments including site geoid separation and building elevation/datum computations. I also produced airport obstacle survey deliverables (including control point establishment and obstacle height calculations) and compiled Collision Risk Model (CRM) analysis for obstacles that penetrated relevant surfaces.
