Most pilots in the US learn a GUMPS check:
G – Gas (Fuel on the proper tank, fuel pump on as required, positive fuel pressure) U – Undercarriage (landing gear down) M – Mixture (fuel mixture set) P – Propeller (prop set) S – Seat belts and Switches
Between flying the aircraft, communicating with ATC, and ensuring all the procedures are correctly followed (including monitoring each other) - there is a lot of stuff going on in the cockpit; and things are happening really quickly; you can sometimes get "behind" the aircraft - especially when unexpected things crop up, kudos to the pilots for recognising an unstable approach, going around, and then responding appropriately to the alarms in the cockpit and not being afraid to go around again.
I'd say it takes around 3-5 seconds for each checklist item; calling out, verifying it's in the required state, and continuing to the next one - you're looking at about 30 seconds on average; which is less time than what the pilots would have between going around and coming back for another attempt. Not to mention they're already likely following a missed approach procedure etc etc, so already pretty distracted, and then given "unexpected" (to them) directions by ATC (different circuit direction).
