The Questions That Get Dropped First
Under time pressure, preflight review does not degrade evenly. The mechanical items survive, because they are physical and habitual. What gets dropped is the reasoning: the questions with no checklist box, whose answers are uncomfortable, and which take longest to think about honestly. These five are the ones that go first.

One: Am I Current for This Flight, Not in General
Legal currency and readiness for the flight in front of you are different questions. Night, weather, an unfamiliar field, a passenger load you have not carried in a year — currency is specific to the flight, and the honest answer is often that you are legal but rusty for this particular combination.
Two: What Is the Wind Doing Where I Am Landing
Departure winds are the ones you look at because they are in front of you. The crosswind that matters is the one at the destination at arrival time, against the runway you will actually be given, in an aircraft you may not have flown at that limit recently.
Three: Who Is Waiting at the Other End
External pressure is a real risk factor and it is the one pilots are least comfortable writing down. Someone expecting you, a booking that ends, a passenger who took the day off — none of these change the weather, and all of them change how the weather gets read. Naming the pressure out loud is most of the defence against it.
Four and Five: What Is My Out, and Do I Have the Fuel to Take It
The last two go together, because an alternate you cannot reach is not an alternate. Decide where you would go, confirm the conditions there, and confirm you would still have the fuel to get there after the diversion has already cost you time. FlightReady's six-step assessment asks these in a fixed order for exactly this reason: a question that always gets asked is a question that cannot get skipped because the clock was running.
