An electronic flight bag providing computational services for an aircraft and communicating with aircraft avionics may execute aircraft-design-approved Type-C applications together with non-design-approved Type-A/B on a single processor through specific modifications of the operating system to control memory and processor access thereby providing isolation comparable to that of dual processor systems in which the Type-C applications and Type-A/B applications are executed on different processors.

An avionic weather radar system tracks aircraft orientation with respect to acquired scan radar data to correct the display of the weather radar data for range distortion and orientation changes of the aircraft between radar acquisition and display, reducing image artifacts.

A method of testing the integrity of microprogramming within a computer processor employs a test calculation designed to exercise instructions and to reveal errors in those instructions. The problem of testing instructions using the very instructions which may possibly be corrupt is addressed by developing a signature passed from instruction to instruction providing a low likelihood of a false positive outcome. A time-out system is used in the evaluation of the test calculation to capture a wide variety of other pathological operating conditions.
