The decision
Put every offer against the same project brief and bill of materials. Differences in included equipment and operating conditions need to be visible before prices can be compared meaningfully.
Normalize the scope first
List the aircraft, ground source, station, tether, airborne equipment, mounts and task-specific accessories. For each offer, mark whether the item is included, optional or buyer-supplied. Include transport cases, documents and requested spare parts as separate lines.
A component price and a complete-system price describe different purchases. Bring them to a common scope before judging the difference. Record model references so that later revisions can be compared with the original proposal.
Preserve the original specification labels
Keep rated, continuous, maximum and peak power in separate fields. Retain voltage ranges, units, conditions and any specified duration. Use the supplier’s current documents to resolve unclear figures instead of treating every headline number as equivalent.
For cleaning equipment, retain nozzle, pressure, flow and environmental conditions attached to performance figures. For lighting, distinguish output from illuminance and coverage. The same principle applies across the quotation: preserve what each figure actually describes.
Review interfaces and unresolved questions
Identify who supplies each connection and mounting arrangement. Mark any aircraft compatibility, thermal, cable or accessory combination that remains under review. Ask for the outstanding questions to be answered against the specific proposed configuration.
Also record the documents, drawings and acceptance information needed by your team. A quotation can be commercially complete while an integration question remains open. Keeping both visible makes the next step easier to assign.
Compare commercial terms and support
Record quoted currency, validity, delivery scope, lead time, payment terms and the stated warranty terms. Ask how spare parts and support requests are handled for the selected equipment. Use the actual offer and agreed terms; a general website description cannot settle every transaction-specific detail.
The final comparison should contain the common requirement, each offer’s named equipment, supporting documents, exceptions and open questions. This lets purchasing and engineering discuss the same configuration when deciding what to order, instead of comparing prices detached from their scope.
