Software Level indicates the amount of effort that goes into the development of the given software application.

• Level A (Catastrophic) – Failure prevents continued safe flight because it may cause a crash by disabling a critical function required to safely fly and land an aircraft.
• Level B (Hazardous) – Failure has adverse effects on occupants because it reduces the ability of the operators to operate the aircraft properly. Serious or fatal injuries may occur.
• Level C (Major) – Failure doesn’t have such a large impact as a Hazardous failure, but it’s still very significant and greatly increases the workload of the operators and reduces the margin in safety.
• Level D (Minor) – Failure doesn’t have such a large impact as a major failure, but it’s still noticeable and may cause passenger inconvenience or a routine flight plan change.
• Level E (No Effect) – Failure doesn’t affect operation capability at all and thus has no impact on the safety of aircraft or the workload of operators.

Reliable data on the costs associated with moving to a higher level are scarce, but the little data that are available point to an increase in development costs between 75% and 150%. The increase is caused largely by the increasing objectives to be met for each criticality level. DO-178B allows a great deal of flexibility when it comes to software development because of its objective-based nature since there are many possible ways for a real project to satisfy them.
