Test questions from my Pre-Solo written

[airforceusaf]

I left my Cessna 172r man. in my locker after school today. We had Finals! O well only one quarter left in HS! SWEET> But any way, i have a few questions from my Pre-Solo written test that i cant figure out. If you could help me out it would be much appreciated. Thank you lotz.1.What aircraft catagory does the Cessna 172 fall under?2. How often should the ELT be inspected?3.What actions would you take in teh event of an alternator failure?4.What effect does high density altitude have on an aircraft's takeoff performance?thanks

1, either normal or utility, depending on weight and loading
2. ELT every 12 months, and battery half of the useful life, or one hour cumulative use
3. Turn it off, you dont need an alternator.
4. Longer takeoff roll.

1) Agree with previous post

2) Agree with previous but I'll take it a step further....read 91.207B

3) Recycle it (Turn it off then back on) if that dosen't work begin to turn off any unnecessary radios, lights, or navigation equipment. Remember if the alternator is not working your running off battery power...your batter is only gonna last so long. If you really wanna do it by the book. Pull out the checklist to see what Cessna says to do.

4) Agree with previous post....but why is the take off roll longer. Less air going into the engine....less avaiable power. Prop efficency is reduced...less thrust being produced Those 2 thing togetherwill give you the longer take off roll. Your climb performance will also be reduced

Regarding what to do if you lose your alternator.

siucavflight says to turn off your alternator because you don't need it. I don't know if that's supposed to be an april fools joke but that is a really stupid statement. Generally, you want to try recycling the "alt" half of the master switch and if that doesn't fix the problem leave the "alt" half of the master switch off and land as soon as you can because the battery isn't going to last long.

i'm brutally intoxicated when i practice 172 emergencies on fs2002.... you should practice the same..

if you can do it when you're hammered on fs, chances are you have a *shot* of SURIVIVING in real life when you're sober.


*shot* = minute possibility

note: it took me 12 minutes to make this post without spelling errors

but to be a jackass... as if i wasnt above... remember that only the bolded parts of the POH that are 'supposed' or 'suggested' to be required for memory. so if you crash and die beyond (further along the checklist for engine failure or whatgever else can be ontherher))E those parts tbe ntsb can suck on mah bawls.

im 99.9[edit : 99.999999999999999999999999999999999999999999999999999999999999999]% sure im full of drunk on the lat part but due to the preceding precaution ^^^^^^^^^^^^ i am not liable for my posts.

That is what I said, shut it off. Bring it back on if you want. But losing electrical power in a 172 in VMC is not really a big deal.

Question 3

Regarding the alternator, First and Foremost . . . Don't forget to FLY THE PLANE.

Regarding the alternator, First and Foremost . . . Don't forget to FLY THE PLANE.

Yes, that is maybe a better way of seeing it. In my 1500 hours of dual given I have lost I believe 4 alternators. And each and every time my students went into a panic. I would simply let them know that it was not a big deal, the plane will fly just fine without it. Two of them paniced so much that I believe that if this happened to them alone they would have crashed. Now as part of the PPL training with my students I will shut off all of the electrical of the airplane and let them fly it that way for about 30 mins just to show them that they do not need to panic.

Actually siucavflight, what you said was, "3. Turn it off, you dont need an alternator." You didn't say anything about turning it back on. Yes the airplane will fly just fine but if you just turn it off and don't worry about it (after all why should you worry about it, like you said, "...you don't need an alternator.") you run the risk of depleting the battery and losing your communications. That can snowball into a lot of distractions depending on the airspace you're in, don't you think?
