Frequently Asked Questions

This sticky contains links to previous threads where commonly asked questions have been addressed. It's not all-encompassing, or intended to stop anybody starting new threads, but hopefully will save re-inventing the wheel too often.

If anybody thinks other threads or links should be added in, please post them below and I'll take a look and if appropriate add them to the list with my thanks. Also, don't forget there's an excellent "sources of information" sticky on tech-log.

Safe testing,

What is the state of the art on flight testing airborne computers controlling such things as flight controls, autopilots, glass flight decks through to pax entertainment systems.?

Do we TPs and FTEs just wait for or induce some failures and then assess the consequences or do we examine statistics to highlight problem areas?

A seperate thread may prove to be significent.

There's now almost a sub-industry of testing & the units required for this. The main item is known in our company as a "System Integration Test System (or Rig) SITS or SITR. This usually contains both the main Avionics (AP, FMS, sensors, displays, Input/Output devices etc) plus a radio rack and sub-system rigs such as Flight Control units, Stall Computers, FADECs and so on. Backing all these, are simulation computers to allow the system to "fly" and to set individual inputs & discretes for logic verification etc.

Some companies have plans for complete rigs so that the entire integrated systems can be tested before the airframe is even built.
