Those are some pretty interesting responses. Some may even hint as to why people sometimes land gear up.
Using an acronym such as GUMPS is not a silver bullet by any means, however receiving proper initial training and good consistent habit building is critical to safety in aviation.
In 1970, GUMPS was one of the first things I learned about flying. I was taught to repeat it several times from entering downwind to touchdown and still do it today, probably excessively, but I can live with that. It only takes about 5 seconds to run through it. It does not prevent or exclude doing other, or additional pre-landing flow, or checklists and can easily be performed in the most demanding high workload environments and aircraft. It has saved me on at least one occasion through more than a few thousand hours of commercial flying across the US and several different countries.
Another valid reason to be in the habit of constantly repeating it, is because it's possible, or even likely that one of the items may not apply just yet, but will in the next phase.
If you’ve learned to do GUMPS once on downwind, you’ve been setup for failure. As with all things good in life, once is never enough. Again, it only takes a few seconds, and for that it’s cheap insurance. Sometimes people have questioned why I do GUMPS so many times prior to landing. Well, how many times do pilots make a mistake simply because they forgot something. Thankfully, I have ALWAYS caught myself somewhere on downwind, because of the ingrained habit of repeating GUMPS over and over.
The cool thing about GUMPS is, at least some portion of it can be used on every aircraft you will ever fly. I even use it in helicopters even though it's mostly useful in the pistons and the complex.
If you think it doesn’t apply to the current aircraft you fly, or only the ‘M’ applies or the ‘S’, then you’re missing the point. You should be utilizing the entire word GUMPS in every aircraft you ever fly, even if that one thing isn’t there, so the day it is there, you have no chance of missing it. This is good habit building.
Having the habit of using it sets you up to be safe in everything you will ever fly. Even if your ‘U’ is fixed, you should still be in the habit of looking out the window and seeing your gear down through the use of WORD and then ACTION.
It’s all about good habit building and GUMPS is an easy acronym to learn, remember and utilize and it could save your bacon one day. If you know of something better, let us know, because I desire to continue being the safest pilot I can and I’m not to old to learn new things.
When it's all over, would you rather hear, "Man, that guy sure went through GUMPS a lot", or would you rather hear, "Man, that guy forgot to...".
Aviation is full of acronyms and many can be extremely useful.
