The DE will want to see that you know that checklists are important and that
you use them appropriately. Matt makes a good point, there are Do first and
verify type ops or phases, but there are also Checklist first, do second and
verify type ops or phases. The point is that when you move up into faster
and more complex airplanes you must be able to use good judgment to discern
between the two. For instance, the cruise portion of our Aztec checklist
only has a couple items with the only action items being to close the cowl
flaps and to lean, but, it mentions verifying everything that should have
been performed in the climb checklist. Most twins have specific fuel tank &
crossfeed settings for different phases of flight, if you switch between
airplanes your mind will mix them up at one point or another unless you're
in the habit of using the checklist. There will be a day when GUMPS will
have a lot more letters in it.
