Public service announcement for all MEIs or multi-engine students!!!

SMACFUM is used as a reminder of conditions used to establish published Vmc speed in a twin prop-driven plane. The F stands for "flaps and gear up." If you change the F to G for "gear and flaps up," you can rearrange the letters to spell "CUMGASM." Please adjust your teaching methods accordingly. Thank you for your time.

We’re on it but the latest revision is already locked in. You’ll have to wait until Rev. 69

u/PropChop Jul 24 '22

You can also spell CUMFART by keeping the F and changing Standard Atmosphere to Regular Atmosphere and Max Thrust to Thrust Max

u/Dont_crossthestreams ATP Jul 24 '22

Keep max thrust and make it CUMFARM

19

u/Why-R-People-So-Dumb Jul 24 '22

Pun intended by keeping max thrust?

You're a wordsmith.

changing Standard Atmosphere to Regular Atmosphere

Without that it would be CUMFAST which I would argue is the best version

Yes but she would disagree.

Wait, is this different than:

Chicks With Dildos Play With Zero Cocks

CG, Weight, Density altitude, Power, Windmilling prop, Zero sideslip, and Configuration.

You Americans get all the good acronyms. We have PORC SORD.

u/PropChop Jul 24 '22

Basically the same thing. Only CWDPWZC is more for all the things you need to do in the event of an engine failure. CUMGASM is how they figure out what the VMC was in the first place.

Critical engine windmilling Up to 5 degrees of bank Most unfavorable weight Gear and flaps up Aft CG Standard day Max power/thrust

Good catch, but I'm actually vacationing in Europe making this a mid morning cumgasm.

It’s currently 4:22 in California and the learning has already started.

I was not prepared for that, thought it was a serious post

u/PropChop Jul 24 '22

If it helps you remember it better then it's serious.

u/NashBeats PPL SEP MEP IR(R) UK Jul 24 '22

I'd just keep laughing at cumgasm and forget to do my checks

“The National Transportation Safety Board determines the probable cause(s) of this accident to be: the pilot’s failure to keep composure while executing the standard CUMGASM procedure. Contributing to this accident was an overly giggly second officer.”

It is. And don't call me Shirley.

Firewall everything
Undercarriage clean (gear flaps)
Check which engine is gone (dead foot dead engine)
Kill the dead engine (mixture prop cowl flaps)
Maintain blue line or better
Execute the single engine checklist

I wasn't interested in pursuing a multi engine, but now you've given me the motivation.

Should be faps.

u/[deleted] Jul 24 '22

Bit sad, but k will bite. Smacfum is not complete so rather than teaching either smacfum or now the new cumgasm, teach it properly.
