Weight Analytics (WA) Tool from ALTAIR

WA Tool for Weight & Balance Management at AHD

Abstract

Weight Analytics Deployment for Helicopter Engineering

The management of product’s weight and Center of gravity is essential to all kind of aircraft. Weight is equal to performance &

efficiency. Weight Analytics Solution provides a robust database system capable of collecting data from different sources and

performing enhanced business analytics operations. ALTAIR developed helicopter-specific features to the software which go beyond

the generic scope of a weight management database:

• Fuel consumption management and visualization

• Mission simulation

• Helicopter configurator

• Weight & CoG tracking during development projects

• Weight & CoG trend forecasting Legacy data out of up to 50year old systems have been migrated into Weight Analytics solution.

Powerfull W&B Tool is needed

ALTAIR Weight Analytics is the solution

Main requirements to Weight Analytics Tool are

1. Enable Product Structuring / Product Configuration on n levels (hierarchical)

2. Enable different views of the same Product (ATA, Functional, Generic, …)

3. Display Mass Point Diagrams

4. Weight Maturity Management (estimated / calculated / weighed)

5. Mission Simulation / Flight Envelopes

6. Risc & Opportunity Management with Probability

7. Project History Reporting and Follow-Up

8. HiQube: Delta Drill Function

8. HiQube: Delta Drill Function

17

The comparison of mass data on product structures, for example at different times, is one of the most important requirements for any type

of analysis. WA provides a very powerful tool to investigate on these differencies using the «Delta Drill» graph, where differencies are

shown along the levels of the BoM structure as a contribution (plus or minus) to the difference.
