I just read it on avweb; I don't know anything more about it.
NASA Langley Research Center is conducting research to examine pilot experiences in the general aviation cockpit. Of interest are problems while flying, special equipment brought into the cockpit, and any individual characteristics that might imply a special design
consideration. Answer NASA's survey to help flight-deck designers
understand current cockpit configurations, and direct them toward more beneficial future design features. You must be a current pilot, former pilot, or student pilot who plans to solo, and possess, or have applied for, a third-class airman medical certificate. All responses are anonymous and are not recorded.
