Too Tired to Fly

 

I used to think fatigue just meant needing more coffee. Then I read the aeromedical chapter for this class and realized it's way worse than yawning through a lecture. The FAA handbook says fatigue can seriously mess with your ability to focus and perform (Federal Aviation Administration, 2016). What stuck with me is how sneaky it is. You dont feel dangerous. You feel normal, just slower.

Fatigue isn’t just lack of sleep. Sure, all-nighters are bad. But it also builds up from stress, long shifts, dehydration, hot flight lines. Symptoms creep in slow. Reaction time drops. You miss details. Decision-making gets sloppy. The handbook mentions you start accepting risks you normally wouldnt because thinking through alternatives feels like too much work (Federal Aviation Administration, 2016).

Heres the scary part. Fatigue hits experienced mechanics and pilots just as hard as new ones. Maybe worse, because veterans trust their skills to carry them. But skills don’t help when your brain cant process info right. The FAA says heavy fatigue is more debilitating than three alcoholic drinks (Federal Aviation Administration, 2016). Nobody would work on a plane after three drinks. But people show up fatigued all the time.

After fourteen years on the flight line I get it. Sometimes you’re on hour ten of a twelve-hour shift and the jet still needs fixing. Thats when mistakes happen. You torque a bolt wrong. Skip a step. Let someone else sign off on something you didn’t fully check. Fatigue turns good techs into risky ones and nobody notices until its too late.

The Dirty Dozen lists fatigue as a main contributor to human error (FAA, n.d.). I’ve seen guys push through because the mission matters, because admitting you’re tired feels like letting the team down. But thats exactly when stuff breaks.

For me this means actually checking how I feel before work. Not just grabbing an energy drink and pushing through. Because the alternative is finding out I was too tired when something goes wrong.

When Everyone Knows Something and No One Knows Enough

I read a lot of accident reports in my job but the final report on the LATAM A320 collision in Lima really stuck with me. It shows how fast things go wrong when departments just stop talking to each other.

The crash happened when an airport fire truck drove onto the active runway while the plane was taking off. No clearance, nothing. Two firefighters died. What bugs me isn't just the crash itself. It's all the little organizational failures that made it possible.

The investigation showed the airport authority, emergency services, and air traffic control never actually met up to plan this response time exercise. Controllers didn't even know about new taxiways. The emergency crews thought their exercise clearance meant they could use the runway too. Nobody used proper radio phraseology. And get this, the tower found out about the exercise like ten minutes before it started. Everyone knew something but nobody knew enough. That breakdown is what let a runway incursion happen.

From where I sit in safety management, this crash is a wake up call. Safety culture isn't about being the smartest person in your department. It's about actually communicating with the other departments. Operations, emergency response, the tower, everyone needs to know what everyone else is doing. When one group changes something or starts a drill without telling the others, the whole system loses track of what's happening. That's why these safety publications actually matter. They give us real stories we can use to check ourselves. Are we really sharing information like we think we are?

If I could get my organization to remember one thing from this report, it's that sharing information isn't optional. It's basically the whole thing. Using this publication in our meetings helps show that we're all part of the same safety net. And that net only works if every department stays connected.
