There are other situations-electrical outages, broken wires, disconnected grounds, monitor screen glitches, circuit breaker failures-that can also result in loss of primary flight display (PFD) data. The published MTBF figure is, however, related to the solid-state “gyro” system. ![]() Garmin, for instance, advertises a MTBF of 10,000 hours for the G1000 system. ![]() One of the great selling points of glass cockpit displays is the mean time between failures (MTBF)-or average number of operating hours an individual unit should be expected to work before a total outage-is astronomical. So it’s a really good idea to think about and practice for the scenario where your glass cockpit display goes partially or completely dark, so you don’t find yourself having to try to figure out what to do without a safety net if it happens to you. But like an engine failure at night in IMC over water while picking up ice, it’s one of those that, if it does happen, carries with it some serious consequences. What happens when it fails?įirst, I’m going to tell you that this is one of those things you almost certainly are never going to have to worry about. These days, however, those same instruments often have been replaced with what is essentially a computer screen. ![]() Back in the days when each instrument was a separate, physical thing instead of a software construct presenting symbols or alphanumeric data, their presentation was relatively well known and predictable. Instrument pilots get to learn what to do when instruments or the systems powering them fail and how to get back on the ground with what’s left. Among the first things pilots learn is what to do if something goes wrong.
