Frequently asked questions

Implementation timelines, offline and online capability, dispatch integration, logging and more. If your question is not covered here, contact us directly.

Our operation starts very soon — when can we have the software?+

Normally an implementation is started and finished within 2–3 months. This is highly dependent on which features are required, so it can be both shorter and longer. We also offer an expedited on-site implementation lasting 1–2 weeks at an extra cost.

Is documentation support available with your solutions?+

Yes — documentation support is included in the setup fee.

Does the performance application work without an internet connection?+

Yes. The performance data for your fleet — manufacturer SCAP modules, performance tables or digitised AFM data — is installed on the device, so takeoff and landing calculations run fully offline. You will still need connectivity to synchronise new configurations, airport and obstacle databases, and to upload log files.

Which sources of performance data do you support?+

All of them. Where the manufacturer provides a SCAP module (the IATA standard for computerised airplane performance), we use it — as a first-principle module solving the certified performance model directly, or a second-principle module computing on pre-calculated data. Where no SCAP exists, or another basis suits your operation better, the same engine runs on RPM/RTOW table lookups, digitised AFM performance charts, supplements and custom data sources — every one validated against the certified reference.

Can performance run online, integrated with our flight planning system?+

Yes. Every aircraft type we support can run server-side takeoff and landing performance, and the Performance API connects it directly to your flight planning and dispatch systems. Calculations and dispatch releases remain synchronised with the crew’s EFB, so the flight deck and the back office always work from the same numbers.

Do you support dispatcher-side performance for FAA operations?+

Yes. The Web Performance Dispatch UI gives dispatchers full takeoff and landing performance in the browser, supporting the joint dispatcher–pilot responsibility under FAA Part 121. Releases can be delivered to the aircraft over ACARS or AIRCOM datalink, and every calculation is logged in JAWS.

What is our backup if an EFB device fails?+

DS Contingency Solution provides performance through any standard web browser, on any device, powered by the same DS Performance engine as the EFB app. If an iPad is lost, damaged or unavailable, the operation continues.

Can you validate our performance data and run performance studies?+

Yes. DS Analysis Tools tests and validates the calculation engine, airport & obstacle database revisions and manually engineered data such as EOSIDs — and supports studies from citypair analysis and batch RTOW runs to airport authority assessments.

Do you log the calculations — and for how long are they available?+

Yes, we do. Currently there is no time limit: all logs are stored, always. We can easily tweak retention to suit your needs if shorter periods are required.

What minimal system requirements do you have server-side?+

We offer a cloud-based solution for the back-end systems, so regardless of your scale of operation or which products you use, getting started is easy and secure. Contact us for specifics.
