Could someone explaine what a GUMP test is ? Seen it in a book that is
something you do on landning. Part of a checklist or what ?

This checklist is a final safety measure to ensure that the basics
are remembered before attempting to land. This particular acronym is
made for piston-powered constant-speed prop equipped, retractable gear
aircraft, but I guess the essentials are still valid for simpler and
even more complex aircraft. Anyway, it goes:

Gas- Make sure fuel selector is set to "Both" or the tank with the most
fuel. (Gasoline being the American term for fuel or petrol). Also turn
on fuel pumps if your plane advises fuel pumps be turned on for landing.

Undercarriage- A long word for landing gear. Make sure that your gear
is down and locked.

Mixture- Mixture rich, or at an appropriate setting if operating at
high density altitudes.

Prop- Propeller forward or set for climb. In case a go-around is
necessary, propeller has to be ready for full power application.

Safety- Most of the time there is an "S" at the end to spell "GUMPS".
The "s" is a catch-all to remember some items needed on certain
aircraft, or can be used to check that Seat belts are secure.

GUMP is 'old' mnemonic for 'Gas (fuel/tank/pump selection); Undercarriage
(gear down); Mixture (assumed rich); and Prop (constant speed - high
pitch). I still use this on downwind -covers most of the critical items.

G Gas, fuel selector correct?
U Undercarriage (landing gear ) down?
M MIxture rich?
P Prop at High RPM?

It works for me..

The one I was taught to use was C-GUMS:
C arb heat on
G as
U ndercarriage
M ixture
S eatbelts

Before constant speed governors were all but universal on variable pitch
props, there were props that could select prop pitch coarse ( for cruise)
and prop pitch fine,( for approach and landing). P stands for 'prop pitch
fine' (not high...)
But sure enough, the engine note increases when you select fine.

It means: "Flying is like a box of chocolates you never know what the landing is
gonna be like until you try one."

I assuming you meant FORREST GUMP that is ;-)

GUMP is a mnemonic to aid in remembering the most important pre-landing
preparation. The letters stand for (G)as, (U)ndercarriage, (M)ixture, and (P)rop.
Gas - check fuel switch for proper position and turn on the boost pump,
Undercarriage - make sure the landing gear is extended,
Mixture - Normally, full rich so you are prepared for a missed/go-around in the
event it becomes necessary, and,
Prop - in the full forward position, also for a possible go-around.

If you do nothing other than follow these steps you probably won't go too wrong
on landing. I use it religiously and have never had a gear-up landing.

GUMP is an acronym used by pilots of high-performance aircraft to help them
make sure they do their landing checklist--G for gas (on the fullest tank),
U for undercarriage (gear down and locked), M for mixture (rich), and P for
propeller (flat).

I use B-GUMPS in the Arrow...
[B]ooster pump
[G]as -fuel selector
[U]ndercarriage
[M]ixture
[P]rop
[S]eatbelts

On take off, when I cross the hold short line, I use another phrase...

"Lights" - turn on strobes and landing light whenever I am on the
runway. The boost pump switch is on the same panel so I can verify it's
on too.

"Camera" - turn on the transponder so ATC gets my picture.

"Action" - check handles forward. Prop high and mixture rich. For high
DA takeoffs I keep the mixture where I set it at full blast run-up.

I modified the GUMPS to a GUMPERS check as follows:

G Gas - Fuel selector / pumps set correctly?
U Undercarriage - down and welded? (I only fly fixed gear so far)
M Mixture - Mixture set at least 50 degrees rich of max EGT?
(I fly from a 6000' high runway)
P Propeller - Turning? (I only fly fixed prop so far)
E ELT - Tune 121.5 long enough to verify that I'm not yelping.
R Radios - Tower and Ground frequencies set correctly?
S Safety - Seatbelts tight? Windows closed? etc.?

The best time to do the ELT check is after you park (so that you catch the
fact that your rough landing set it off) and I try to remember to recheck
it then, but putting it in the GUMPERS check ensures that I at least check
it once AND that I have the opportunity to hear the ELT from the plane that
crashed fifteen miles from the airport.

In Australia I use SUMFHB on the downwind leg. It seems to do the job well:

Speed - for lowering the gear
Undercarriage - down with 3 greens
Fuel - on fullest tank - pump activated
Mix - full rich
Hatches/Harnesses - secure/locked etc
Brakes - brakes still have pressure after gear has been lowered.

How on earth do you pronounce that?

I always teach my students to do the "CGUMPS" at midfield when doing
landings or touch-goes.

C - Carb heat on
G - Gas on both tanks
U - Undercarriage - down and welded!
M - Mixture - SET
P - Power - set (usually 2100 rpm for C-150)
S - Safety - Seatbelts, Landing lights

Try it!

I think he meant HIGH PITCH to mean "HIGH SPEED" "HIGH RPM" whatever.
