And like every other technology, autopilots have their limitations. For one, they have to be set up correctly-along with the navigation equipment-to reliably follow a heading and descend along a glidepath. Details like when to take over from the autopilot, how you might handle an equipment failure-if you notice it-and even whether to let Otto fly the missed approach or do it yourself need to be worked out ahead of time. Thats the short version of why we might want to consider hand-flying the approach. Lets expand on them.
