HTMPFFIC

I was taught this Pre Take off checklist by an old flying mentor who had been a commercial pilot, flying everything from Tiger Moths to large commercial jets. He used it on the 50+ types of aircraft he had flown in his career. 

H - Hatches and harnesses secure

T - Trim set for take off, Throttle friction set

M - Mixture full rich, Mags on Both

P - Propeller pitch full fine

F - Fuel, sufficient quantity and fuel tap and pump on

F - Flaps set for take off

I - Instruments, reading correctly, temperatures and pressures ‘in the green’

C - Controls, full and free movement and working correctly.

It’s easy to remember and work through. Every one of the items needs to be checked every time. Neglecting a single one could result in a failed takeoff or crash. Trying to remember them without the checklist results in a justified fear that you might have missed something. The checklist dramatically reduces mental workload in the cockpit before take off.

By contrast there’s an engine failure brief pilots give themself just before they start the takeoff. Engine failures are dynamic and require lots of judgement (Check out QF 32 or Miracle on the Hudson if you want insight into this). You can't build a checklist for that. The brief reminds you of the critical decisions needed if the engine stops and speeds your response in the unlikely event it happens.

Checklists create mental Capacity to deal with more dynamic events.

To be Avoided

Imagine waking from surgery to find that the wrong leg had been amputated. That would leave you without a leg to stand on. An Austrian surgeon that made the error last May is in a similar position. The surgeon claimed human error which wasn’t well viewed by the court awarding damages.

Medicine, emergency response and aviation, are all fields who have widely adopted checklists as a way of reducing (preferably eliminating) errors like these. 

Checklists make a massive difference where there are one or more of these factors at play:

• High consequences for a mistake, like marking the wrong leg, forgetting the fire hose, or not closing the aircraft door.

• Reliable repeatability, like having everything you need in the operating theatre, on the fire truck, or in the cockpit.

• Mundane tasks, like double checking patient details, fire truck maintenance, and pre take off checks.

• Rapid response required, like a patient going into cardiac arrest, someone trapped in a burning building, or an engine failure over the Hudson River.

• Lengthy time intervals between occurrences, like any of the above professions doing annual compliance checks.

A checklist removes mental load from some activities, increasing the Capacity for responding to others. While the Austrian Surgeon’s claim that the ‘wrong leg’ was human error is probably true, the negligence comes from overlooking one or more critical checklists specifically designed to avoid such mistakes.

Where could you benefit from a good checklist?

Some examples might be:

• Reporting

• Recruitment

• Preparing to present

• Responding to complaints

• Customer service

• Making products

• Frontloading your week

• Holidays

Decision-Making Capacity

Have you ever reached a point where you can’t even make a simple decision? End of a long day, fatigued and asked to choose between 2 simple food options. It’s a strange feeling not being able to bring your decision making ability to bear, even though it's not a difficult decision and consequences are low. It’s called decision fatigue. And while there’s still debate about whether it comes from making too many decisions and running out of capacity, or from mental exhaustion and stress is unclear. Either way, it seems we have our limits. Like the VO2 max we looked at here, we need to either increase our capacity via skills, tools and exposure, or clear capacity somehow.

Some examples of clearing capacity…

Former US President Barack Obama was said to have a whole wardrobe of identical suits in blue or black. It meant there was no need to decide what to wear each day. It was going to be a suit, and the occasion dictated or blue or black.

A speaking colleague, Shil Shanghavi, pre-decides and prepares most of his food for the week, eliminating food decisions during the week.

One of my mentors, Peter Cook, has a pre-decided work routine when he flies. Rather than trying to decide what movie to watch, he meditates until the seatbelt light goes off and then gets into some writing. He describes it as a decision he made once and then sticks too, so he doesn't have to make it every time.

Are there decisions you could unload by making them in advance or once rather than often?
