Quiz Screaming Emu on the PA-44!

Aww, screw that, it might have just been a Riddle thing.

How about:

"Talk me thru the immediate action items after an engine failure and what you're looking for"

What I'd do depends on a couple of things. What phase of flight I'm in when the engine fails, what the single engine performance is that day, and whether or not I can figure out why the engine is giving up the ghost.

For example, if I'm flying a long in cruise and an engine shows a very low oil pressure, and CHT and Oil Temps are extremely high, odds are there isn't enough oil and I'm not gonna be able to salvage this one. If I catch that early enough I'll shut it down before it dies so its on my terms, I know when its coming, and it makes things less complicated.

So I'd go through the memory items, "identify, adjust power in operating engine, and maintain at least Vyse (88)". But since the engine is definately toast, I wont continue on with the non memory items such as checking the fuel selectors on, turning on carb heat, etc, because it wont make a difference. I'd just go right on to the securing procedure. Make sure that the engine your'e gonna feather is the right one (move throttle up and down and see if you get any change in manifold pressure, rpm, etc), then "left throttle-idle, left prop-feather, and left mixture-idle cut off". then on with the non memory items.

do I pass?

Say you're in cruise flight, over the Mojave on V105 flying westbound and you have the same parameters as mentioned above. You'd abandon troubleshooting, shut down and feather the prop?

It's dusk, legal VFR and you're enroute to PSP out of IFP.

depends how high I am, how close to an airport I am, what my performance is without the other engine, and whether or not I think that I'm going to be losing the engine anyway.
 
Re: Quiz Screaming Emu on the PA-44!

Well, you're on climb out of 5300, you're ISA +15, and you're 80 NMs sw of Bullhead City.
 
Re: Quiz Screaming Emu on the PA-44!

if that was the case, as soon as I noticed the problem I would be climbing as much as I can to prepare for when it does die. I'd ride that engine for all its worth because of the terrain around, and I'd be heading straight for the nearest airport (which appears to be KTNP). Then I go have a beer.

I wouldn't simpily feather it because SEROC at 5,300 with 30C on the ground is about -50fpm, and my single engine service cig appears to be about 2000 ft. Definately not high enough.
 
Re: Quiz Screaming Emu on the PA-44!

Good, that's what I was hoping to hear.

Speaking of feathering, does the Seminole have any assistance for bringing the prop out of the feathered position?

Yup, we have the unfeathering acumulators on ours. I actually have yet to feather an engine. We're definately doing it next flight. This whole course it has either been too cold to shut one down in flight, or we were doin instrument stuff. One flight left to do it though.
 
Re: Quiz Screaming Emu on the PA-44!

Speaking of feathering, how do we simulate 'zero thrust' in the PA-44?

Re: Quiz Screaming Emu on the PA-44!

Speaking of zero thrust, how does adding flaps affect Vmc, and why?
 
Re: Quiz Screaming Emu on the PA-44!

adding flaps will decrease Vmc because the aircraft is now more stable, and the wings are creating more lift (at a given angle of attack). Since you are banked towards the operating engine there is now more force to overcome the asymetric thrust.
 
Re: Quiz Screaming Emu on the PA-44!

Bonus question. What force, when banking, is helping to counteract the asymmetric thrust?

what is the horizontal component of lift alex.
 
Re: Quiz Screaming Emu on the PA-44!

Circle wins a square!

Like Clint Eastwood says, "A man's got to know his limitations". What are the following:

Max ramp weight?

Max takeoff weight?

Max cargo compartment weight?

Re: Quiz Screaming Emu on the PA-44!

Just as I remember! Scarily, I haven't touched a Seminole for 11 years.

Speaking of time, say your rich distant relative dies and leaves you a part-61 training outfit with one PA-44. What types of inspections are required to use this aircraft for flight training, if any?
 
Re: Quiz Screaming Emu on the PA-44!

I gotta hit the sack else Mrs. Taylor is going to kill me. But perhaps someone else can take over in a few hours!

100 hour, anual,

Anyway Doug, this was much appreciated and a lot more fun than just stickin my head in a book and goin over stuff over and over again, but unfortunately its 3:15 and I have to get up early tomorrow to go to Cavalier, ND for the weekend. A friend of mine is getting married and I'm a groomsman so I gotta be there for the rehearsal.

Nothin like a weekend in smalltown North Dakota. Especially when last weekend I was in Banff, Calgary, and Waterton. Pictures can be seen here if you're bored (http://www.flickr.com/photos/jriegel/) though the website appears to be down for MX at the moment.

Once again, much appreciated, I'll be sure to post in the announcements when i pass this one. This is one of the few checkrides where I feel really confident about and I dont even have it scheduled yet. Only thing that I feel needs a lot of work is valid times for weather products, that has always been a weak point for me.

Alright, off to bed, take it easy.
