Understanding aviation insurance is vital for industry professionals. This guide covers key terms like Act of God perils, aircraft coverage, and aleatory contracts. It explains important clauses, conditions, and exclusions, helping you navigate policy requirements and principles of indemnity. With this knowledge, you can better manage risks and ensure comprehensive coverage.

Act of God Perils: Natural events outside human control, such as floods, storms, or earthquakes.

Accident: An unexpected, unintended event causing loss or injury.

Aircraft: The airframe, power plants, propellers, rotors, and appliances form part of the aircraft at the inception of coverage, including parts detached and not replaced by other similar parts.

Aleatory Contract: A contract where the performance of at least one party is contingent on the occurrence of an uncertain event.

Here we consider a broad overview of EASA regulations, focusing on the European Plan for Aviation Safety (EPAS) main objectives, priorities, and how they shape quality assurance efforts within the aviation sector.

EASA Regulations Overview

EASA regulations are comprehensive, covering all facets of aviation safety and enabling the demonstration of compliance with the relevant ICAO Standard and recommended practices. These regulations are divided into several annexes, referred to as "Parts," each addressing different areas of aviation:

Active frost: Condition when frost is forming. Active frost occurs when

(1) the aircraft surface temperature is at or below the frost point, or

(2) there is water in liquid form (e.g., dew) on the aircraft surface and the surface falls to/or below 0 °C (frozen dew).

Sofema Online (SOL) considers both the Legal Framework and applicable Security Regulations

Introduction - Legal Framework and Security Regulations

The legal framework and security regulations governing civil aviation play a crucial role in maintaining safe and secure skies.

  • • These regulations are designed to address the myriad challenges posed by modern threats to aviation, including terrorism, cyber-attacks, and other forms of unlawful interference.
  • • A robust legal framework is essential for setting standards, guiding airport and airline security measures, and facilitating international cooperation.

Sofema Online (SOL) considers the major challenges related to the need to address Cyber Security.

Aviation Cyber Security Strategy Introduction

The civil aviation sector is increasingly reliant on the availability of information and communications technology systems, as well as on the integrity and confidentiality of data.

The threat posed by possible cyber incidents to civil aviation is continuously evolving, with threat actors focusing on malicious intents, disruptions of business continuity and the theft of information for political, financial or other motivations.

Sofema Online (SOL) considers the use of the ICAO 5 x 5 Matrix as a Risk Assessment Tool.


ICAO 5 x 5 Risk Assessment is a widely used risk assessment methodology in the aviation industry. It involves the assessment of the likelihood and severity of a potential risk and assigning a score to each based on a five-point scale. The scores are then multiplied to give an overall risk score.

Sofema Online (SOL) considers the roles and responsibilities related to the performance of Safety Assessment of Foreign Aircraft (SAFA) & Safety Assessment of Community Aircraft (SACA)

Introduction - How are ramp inspections performed?

The Inspection is performed by Authorised inspectors who are using an International Civil Aviation Organisation (ICAO) compliant checklist with 53 inspection items during ramp checks.

Category 2 and Category 3 findings are communicated to the responsible Aviation Authority for information and to the home base of the operator with the request to take appropriate action to prevent reoccurrence.

Sofema Online (SOL) looks at the use of Risk-Based Oversight in support of the Aviation System

Introduction - ICAO Drivers for Risk-Based Oversight

ICAO recognizes the importance of risk-based oversight systems in aviation and has developed a set of drivers to support their implementation. These drivers are designed to help aviation authorities and operators understand the benefits of risk-based oversight and to provide guidance on how to implement such a system effectively.
