Maximum weight

The maximum weight is a critical limit in the development and implementation of projects, particularly in the aerospace industry. It represents the absolute upper limit for the mass of a system or component that must not be exceeded. Exceeding this maximum weight can have serious consequences and lead to the entire project no longer being feasible.

Meaning of the maximum weight

Costs

Material costsHigher weight often requires the use of more materials, which increases costs. In addition, more expensive, lighter materials may be necessary to reduce the weight if the maximum weight is exceeded.
Transportation costsHeavier systems or components are more expensive to transport, which increases the logistical costs.
Operating costsFor aircraft and spacecraft, higher weight leads to increased fuel consumption, which increases operating costs over the life of the project.

Legal requirements

Certification and approvalMany projects, especially in the aerospace industry, are subject to strict legal regulations and certification requirements. Exceeding the maximum weight can result in a system or component not receiving the necessary certifications and therefore not being allowed to be used.
Safety regulationsLegal safety regulations often stipulate maximum weight limits to ensure safety during operation. Exceeding these limits can lead to legal consequences and liability issues.

Technical feasibility

PerformanceThe weight of a system directly influences its performance. For aircraft and spacecraft, excessive weight can affect flight performance, resulting in reduced payload capacity, shortened range or reduced maneuverability.
Structural integrityIncreased weight can compromise the structural integrity of a system, leading to an increased risk of failure or accidents.

Management of maximum weight

To ensure that the maximum weight is not exceeded, careful weight management is required throughout the entire project life cycle. This includes:

Regular weight monitoringContinuous monitoring and documentation of the weights of all components and subsystems.
Weight optimization: Use of lightweight construction methods, advanced materials and optimized designs to minimize weight.
Risk managementIdentification and assessment of risks that could lead to weight overruns and development of strategies to minimize risks.
