Today I had the aircraft reserved at my flight school for my first
solo where I could 'just go out and fly.' I was looking forward to
this. Unfortunately, things didn't go well when I got to the
airport. First, my plane wasn't in yet. (A frequent problem that
annoys me.) When the student got back in with the plane, he told me
the radios were intermittant, so I chose another plane that was
available on the schedule, and out to the ramp I went. During my
preflight, I found that the checklists were gone. Damn- off to the
pilot shop I went and I bought one of those plastic Checkmate
checklists. Anyway- back out to the ramp to restart my checklist.
Unchain the airplane, inspect everything, and discover that the tail
beacon was haning in the rudder hinges by it's wires! Damn I can't fly
this thing- and I blew $15 on this stupid checklist.

Back to the office where I found my favorate plane had become
available, and I ended up having a fantastic flight over the Queen
Mary, Long Beach, looking out toward Catalina Island, and the coast.
It was absolutely fantastic weather, not a cloud in the sky, 15 mile
visibility, and the dew point down in the negative numbers (never
heard that on the ATIS before today.)
-------
Anyway, now that I have shared the high points of my day, back to my
question. On this fancy-schmancy checklist, it has something under
the landing portion as follows:
Landing:
Flaps - 30 deg or as req
Speed* 55(63)
GUMPFS

My question is this- What does GUMPFS mean. I can't remember ever
seeing that before.

Maybe it is an acronym for pre-landing checks. I'll take a shot:

G - Gas (check tank selector)
U - Undercarriage
M - Mixture
P - Not sure, but since somewhere carb heat should be on, maybe this is it?
F - Flaps?
S - Seatbelts

I learned SEGUM

S - Seatbelts
E - Carb heat (don't ask me, I don't get it either)
G - Gas
U - Undercarriage
M - Mixture

Speed (prop speed)? --not sure, I've been flying pipers, where we use
BCGUMPS, but same idea.

BCGUMPS translates to:

Boost pump
Carb heat
Gas (fullest tank)
Undercarriage
Mixture rich
Primer in-and-locked
Seatbelts

I assume GUMPFS is something equivelant

G - Gas
U - Undercarriage (for retracts/floats)
M - Mixture
P - Prop (for variable pitch props)
S - Switches (Lights, boost pumps, etc)

No idea on the "F" though.

Everywhere I've heard it, "P" is for propeller (full forward, in
case of a go-around). Like "undercarriage", applies mostly to
complex planes.

People wanting to mention carb heat do C-GUMPS.

I was taught, and do, GUMPS checks on downwind, base, and final
when I'm flying a controllable prop plane with retractable gear.

Otherwise, I don't like it (personally). Because you are constantly
mentioning two things you have absolutely no control over in a fixed
pitch prop, fixed gear plane, to me it encourages the chanting of
checklists like mantras without meaning or action attached.

On the other hand, that's just my opinion and in any large enough
gathering someone can be counted upon to express the heated opinion
that failing to do GUMPS checks from the start is bad piloting sure
to produce a gear-up landing some day.

Me, I make up my own little chant appropriate to the plane I'm
flying. Since my current plane does not recommend carb heat in
the pattern, has low wings, and is usually leaned for most flights,
I want to check the fuel pump (on) and the mixture (rich) in the
pattern. People who fly with me can tell you I actually say aloud
"fuel pump on mixture rich" while making it so just before I reach
the numbers on downwind, and touch these while saying it again
on final.

> F - Flaps?
> S - Seatbelts

I've never heard the F before, but I suspect you're correct.

> I learned SEGUM
>

> G - Gas

> M - Mixture

I would suspect "E" for engine (since the point of carb heat is to
keep the engine from stopping).

That's another thing I'm not fond of in these mnemonics--to me,
they aren't mnemonic. How often do you hear pilots talk about
"fixed undercarriage" or "retractable undercarriage" planes outside
of these lists? Isn't it usually "gear"? How often do you hear
American pilots talk about "gas" outside of these lists? Isn't it
usually "fuel"? Fuel flow, fuel capacity, fuel reserve, fuel tester....

Ah well.

Complain to the FBO about this, who in turn should come down on their
renters/instructors to get back on time. Shit does happen and sometimes
it is unavoidable to get back late, but if it happens frequently, then
there is a systematic problem which needs to be solved.

The plane is not legal for flight unless the POH is in the plane (we could
argue details on that one for a while, but it's approximately true). In
the POH there should be a checklist. So, even if the convenient laminated
card is missing, you could have still opened up the POH and read the
checklist out of that. That's not to say the pocket checklist shouldn't
be replaced, but it's not strictly essential.

> What does GUMPFS mean.

GUMPS is a standard "mental checklist". It stands for


Gas - fuel selector set to proper position, pump on if appropriate
Undercarriage - gear down and locked, 3 green
Mixture -rich
Prop - full forward (i.e. high RPM)
Seatbelt - fastened

Not every item will apply to every plane. Obviously no gear to check down
on a fixed gear plane, and no prop control on a fixed pitch prop. On
planes with automatic mixture (Katana) there may not even be a mixture
control. Some planes may require other items (i.e. carb heat on in a
152/172).

Also, some people mutate the standard GUMPS. Some people say the S stands
for Safety, and includes not just checking your seatbelt, but windows,
doors, and turning your landing light on. My primary instructor told me
to use the P as Power, and to check carb heat on and select a proper
throttle setting.

I've never seen the F thrown in there, but I would guess it stands for Flaps.

GUMPS does not replace a written checklist, but it's a good mental backup
to double-check you havn't forgotten anything critical. You should get
into the habit of running a quick GUMPS check (shouldn't take more than
about 5 seconds) on final. Don't just mumble the words, as you say each
item, reach out and touch it. I fly both fixed and retractable gear
planes, and I find it simpliest to always use the same GUMPS check on
final. If I'm flying an Archer (fixed gear, when I get to Undercarriage,
I reach out and move an imaginary gear handle. It keeps the routine
constant and helps reinforce the habit.

You should really be thinking the more general "Fuel system properly
configured". In a PA-28, that means the fullest tank, but in other types
it may not be.

On something like a C-152, it just means "check fuel selector is on". On
planes with more complicated multi-tank fuel systems, it may mean "inboard
tanks selected", or "cross-feed disabled", or whatever is appropriate for
that specific type. I seem to remember reading that the Tri-Pacer has
some sort of assymetry in the fuel system and one tank (I don't remember
if it's the left or right) may be preferred even if it's not the fullest
one.

It may also mean to check other things, such as fuel pump on (required in
some types, forbidden in others, optional or simply non-existant in some).

As other have said, it's a takeoff on the GUMPS check, in this case,

G - Gas on proper (fullest) tank
U - Undercarriage - usually for retractable gear, but I also like to
think of it as a reference to the landing lights
M - Mixture as required
P - Propeller full in (for adjustable prop), or Power, which could
also be a reminder for carb heat and other items that are involved in
a power reduction
F - Flaps as required for the landing
S - Safety - seat belts, windows (you do fly with your windows open on
nice days?)

Agreed with the general sentiment (much snipped), but

Gas guage, gas tank, gas station, gas prices, gas up, avgas...

The PA28-161 manual describes p as refering to 'primer in and locked,' this
is a recuring theme with the cadet, as there has been a small (note 'small')
problem with leaks or loss of pressure through the primer system. It sounds
correct though, that in controllable speed planes, to use p for the
propeller.

Left. The right tank is only for level flight if it's less then
1/3rd full. In practice, I always land on the left tank unless I
have a good reason too (or if I forget to switch tanks).

Hello again Dan,

It means Gas Undercarriage (which means wheels and flaps) Mixture Prop
Seatbelt & I don't know what the F is for but I'm sure someone else
does. That never worked for me, I need a W for Wheels.

Well I have been flying since since I was 14 and I am 76 and still teaching. 25 years ago Checkmate met with the small aircraft mfg. and sold them on a great idea.
Checkmate would work with each company and make a visual friendlychecklist for all their aircrafts. From then on checklist became raiser to read and were very accurate.
This is a warning DO NOT EVER use a printed checklist that doesn't have identification on it.
If it has not been copied from the Ops. Manual and laminated do not use it. There was a case about 15 years ago where the chief pilot put checklists from older aircraft into new aircraft with fuel injection. You guessed it on final the students turned on the fuel pumps as listed on the checklist. They lost two aircraft to fires and the third badly damaged. ALWAYS USE A CHECKMATE CHECKLIST. They are all approved by each mfg. and very easy to use.
I have a friend with a 37 or 38 Fairchild and they had a Checkmate for it.
Happy flying
