Accuracy figures in drone survey reports are often residuals on ground control points — numbers that describe how well the software fitted the constraints it was given, not how accurate the model is. This note sets out a checkpoint based validation method,…
Small UAV wings often operate at chord Reynolds numbers where laminar separation bubbles and transition dominate the aerodynamics — exactly the regime where default CFD settings mislead. This note gives a practical verification and validation checklist:…
Manufacturer endurance figures are measured in benign conditions. In a hot summer — typical of the Arabian Peninsula — lower air density raises the power needed to hover while high temperatures constrain the battery. This paper explains the physics from…
Machine learning promises earlier fault detection and fewer unscheduled removals, but aviation maintenance is a regulated, safety critical process with sparse failure data. This paper sets out when a predictive model can add value, the data it needs, why most…
Fine dust and blowing sand shorten the life of small UAVs in ways that rarely appear in a specification sheet. This note reviews the main mechanisms — propeller leading edge erosion, particle ingress into motors and bearings, contamination of optical and…
Engineering organisations in the region publish for readers who switch between Arabic and English, often within one document. Treating Arabic as a translated afterthought produces broken layouts, mixed direction numbers and inconsistent terminology. This note…
