Knowing that each make/model has a specific emergency checklist and procedures to follow during an engine failure, what is your memorized checklist/procedures that you immediately go to for your make/model?
You know the one I'm talking about, the one that you practice while laying in bed in the middle of the night when you can't sleep!
Since the twins I fly are pretty similar, the flows are pretty similar, but it does depend on the phase of flight.
Takeoff/initial climb (i.e. obstacles straight ahead and threatening):
1) Mixture/prop/throttle full, flaps/gear up (should be that way already)
2) Identify (dead foot = dead engine, confirm with engine monitor and instruments showing irregularities), verify, feather, secure (fuel off on dead engine, cowl flaps closed on dead engine, cowl flaps open on good engine)
Climb/cruise (above obstacles when I have more time):
1) Take a look at everything and figure out what's wrong (is it a dead engine or did I forget to change the fuel?)
2) Act appropriately. If I lose an engine in cruise I will probably leave the other engine at cruise power, rather than putting it to full power, but that's because the planes I fly can handle that. If I forgot to change the fuel, well, then it would be pretty silly to shut down the engine.
I've one alternate method for takeoff. After gear is up, move hands to props. Look at your EGTs for a discrepancy vs. normal, and if an engine quits, feather that one immediately. The person who did that method flew out of a very short strip for the plane, and figured that if one quit right after pulling the gear up that he only had a split second to get the dead engine feathered if he wanted to clear the trees at the end. It does offer more room for error on the pilot's part, but I also see the benefits if you execute it correctly.
