How Much Is Enough?

Removing the old autopilot will leave holes in the left panel that would be too ugly if we just covered them, so were going to cut new metal. Since were doing that, the shop has suggested we might consider replacing the backup analog airspeed indicator, attitude gyro, and altimeter with an integrated electronic standby instrument. Yeah, thats probably a good idea, especially right now, as the vacuum attitude indicator has been slow to come alive recently and is probably about to die.

Key Takeaways:

• Modern avionics advance rapidly, leading to quick obsolescence and a continuous cycle of costly upgrades, contrasting with the long lifespan of older equipment.
• Pilots often face a cascade of upgrades, where one necessary replacement (e.g., an autopilot) can trigger a series of additional, sometimes rationalized, panel improvements.
• While acknowledging the safety and functional benefits of new technology, the author questions the high financial investment and short market life of modern avionics, seeking better longevity and value from manufacturers.
