Quantum MX includes a built-in weight and balance calculator that will help you document weight and balance changes. The weight and balance utility will compute a new aircraft weight and balance based on the effect of parts removed and installed.
- The parts removed must be documented properly in the work order to include the weight and station values.
- The parts installed must be documented properly in the work order to include the weight and station values.
- The aircraft empty weight, arm and moment values must be configured.
Configuring the Aircraft Weight and Balance
- Browse to an aircraft view.
Click the Weight & Balance link.
Configure the aircraft weight and balance fields:
moment. The empty CG (arm) will automatically be computed.
The Aircraft W & B page also provides an attachment box where you may scan and upload the official aircraft weight and balance for safe-keeping.
Work Order Weight and Balance Features
Configuring a Work Order for a Weight and Balance Update
- Open a work order for the aircraft.
- Complete the work order discrepancies, work entries, and assign the parts appropriately.
Edit the parts assignments to document the part:
removed/installedstatus. (Reference article: Assigning Parts to Work Entries)
weightvalue should be configured when defining the part in the Parts database. (Reference Article: Parts Management) The part's
stationfield contains the arm where the part is located. WARNING: Quantum MX does not convert math units in the weight and balance calculations. Be careful to use the same units for the weight and station/arm as the aircraft weight and CG values. For example, if the aircraft CG is specified in
inches, enter the part's station/arm in
Calculating the Weight and Balance
From the work order screen, click the W & B link.
Click Create Weight and Balance to add the weight and balance record to the work order.
Review the weight and balance calculations. You may also adjust the individual part
arm values conveniently using the in-place editing links.
When an aircraft is weighed following a maintenance event, you may override the Quantum MX calculated weight and balance changes with manually entered as-weighed values. Click the Override link to enter the values.
Quantum MX will show the
AS-WEIGHED notice. Click Use Calculated Values to clear the manual as-weighed data and re-calculate from the work order parts installed/removed tables.
When the manual override is used, the
AS-WEIGHED indication will display on the generated PDF document. Verify all values prior to certifying and signing the document.
Signing a Weight and Balance Record
The weight and balance record may be digitally signed.
- Assign a mechanic to the weight and balance. The assigned mechanic and corresponding signature will be shown on the printed weight and balance sheet.
- The assigned mechanic will see the standard signature features.
- Click Sign to apply a signature.
Note only the "approval" signature feature is available for weight and balance records.
Downloading a PDF Weight and Balance Sheet
A PDF weight and balance sheet may be downloaded. The PDF will contain your team information and a signature block. Click Print to download the PDF document.
Including Mechanic Credentials
When a mechanic is assigned to the weight and balance, the mechanic cert information will be included in the downloaded PDF. If the document is not digitally signed, signature lines will designate the area where the document should be signed after printing to paper.
Generic Signature Block
Leaving the mechanic selection blank, click the Print link to download a PDF weight and balance document with a generic signature block.
Updating the Aircraft Profile
Click Update Aircraft Profile to update the aircraft profile weight and balance to the newly calculated weight and balance.
A Boilerplate setting is available for the weight and balance report. If no boilerplate is configured, the Quantum MX boilerplate will be used.
If the boilerplate is configured, it will display in the same location and replace the Quantum MX default boilerplate.
To configure the boilerplate for weight and balance:
1. Click Settings -> Lists
2. Click Configure Boilerplate
3. Add a boilerplate for
