@Jo7 I'm kind of hoping people will work with the poster on that particular question. From the way it is phrased, I'm guessing the poster is very new to aviation (and possibly quite young.) It would be shame to ruin their budding enthusiasm...
This is one of those things where I wish we could pull new posters aside and explain the rules real fast in private... Can they be pulled into chats by people who have enough rep to use chats maybe?
Hmmm... All I'm saying is I'd be happy to pull some of these folks aside to explain how to ask better questions. I just worry about them showing up, asking a "not so great" question, being told so by the community and then taking it as a sign that aviation wasn't really for them anyway...
Maybe I should run for mod or something ;). (Which would be a waste of time since I wouldn't vote for me personally...)
I think 9 is about when I got into aviation as well... waaaaaay back in the day when you had to go to the library and check out books if you wanted to learn anything ;)
@JayCarr being a mod won't really help in that regard. The only avenues to drag people into chat are superpings (this lets you ping someone who isn't active in chat, but does not negate the rep requirement) and migrating comments to chat. We can create rooms where <20 rep people can talk, but all of the above requires willingness to participate by the other party. If leaving them a comment doesn't work it isn't likely you'll convince them to join you in chat.
also, just a word of caution when dealing with someone who you think is young. Don't prod them for their age. If they openly acknowledge being younger than 13 then they cannot have an account on stackexchange (not SE policy but compliance with US law)
International law is a funny thing... I assume they'd have to get a guardians permission, and I'm not aware of any way to do that on StackExchange... (Right?)
it only gets enforced if someone goes around saying they are youung. e.g. "Hey guys, I'm 10 and really interested in aviation, what kind of plane did I see yesterday?"
@JayCarr the best is when your infrastructure is perfect, building wide backup power, multiple redundant generators and yet it all still comes down when the diesel trucks can't get in
not personally, but after hurricane Sandy in NYC there were somewhat widespread issues getting fuel to generators
my personal UPS is just so I have enough time to 1) wait 60 seconds to see if it was a transient drop and 2) run pm-hibernate to get shutdown with about 3 minutes power to spare.
> Remaining Runtime............ 11 min.
thats all my UPS buys me at idle load with the monitors awake
@DanHulme I love how suspiciously well placed that camera is. Though, maybe they cropped the final video...perhaps that's more likely come to think of it.
@falstro This is par for the course in the Cherokee - Considering a remote-mounted transponder when I do the ADS-B install so I can stick it in the furthest part of the tail we can reach. Even a couple of pounds would help :P
Didn't help that I had some rather strong thermal activity on final, that cut out just as I got close to the runway. All of a sudden the plane was headed for the hedge at the edge of the airport rather than the threshold :P
@JayCarr Yeah, it's really roomy too compared to the Cherokee for example. As for the landing, yeah, I probably got a little pale, but I remember that I made sure to keep the nose down and use the throttle instead (I almost had to firewall it to stop the sink rate), so I guess that's a testament what proper training will do to you.
not saying that I did everything properly, but at least I didn't pull it into a stall.
You know, I've often wondered this for simulator purposes, how do you control decent with throttle? (Or maybe that's something that should go on the stacks... In fact I think I will.)
I have heard it said on several occassion that when you are landing you need to control your descent with your throttle, and not with your pitch.
Two closely related questions that I think can be answered in one go:
Why do we use throttle instead of pitch to control the decent?
How does this...
@JayCarr The point is: don't bleed off airspeed if you're already going slow. The kneejerk reaction to a high descent rate is to pull back on the yoke, which will kill you. A controlled descent is done using both, but you should never, ever, yank the yoke. If you want to go around, add power and start bringing the nose up to keep the airspeed until you get a positive rate; most approaches are done at Vy, so in that case just keep the speed where it's at and climb away.
The tb10 does approaches at Vx, so unless I want to clear any obstacles, I'd ease forward on the yoke after starting to climb away to speed up to Vy.
actually, I don't know if most approaches are done at Vy. I know a few aircraft where the approach speed is close to Vy; but you get the point anyway
@JayCarr I like to describe the relationship between power and attitude using a level flight slow-down example; you're in the pattern and you want to slow to approach speed, but you're on the downwind leg so you don't want to descend just yet. Pull the power back and start pulling the nose up to maintain altitude, until you reach the speed you want. Then, if you set power correct to begin with, you're done, otherwise add power back in to keep the plane from descending
(or maybe it's time to start the descent...)
Now if you'd pull the nose up to the approach speed attitude you'd trade airspeed for altitude, you'd be at the correct speed, but you'd be climbing. You can pull the power out to start descending back to pattern altitude, but it wouldn't be a very elegant maneuver.
So you have to work with both. Power adds energy to the aircraft, if you don't need it for speed, it'll add to your altitude
if you don't have enough power to maintain speed, it'll use your altitude (and start to descend)
@falstro Yes, well, I'm still hover at two and crossing my fingers for a big raise in the next couple months... Still bugs me that aviation is such an expensive hobby.
@Shalvenay I dunno, I do photoraphy and music production as a hobby as well. I've accumulated a couple thousand dollars worth of equipment at this point. Even so, that's about enough to get 1/4 of the way through my PPL. And then, well, just renting for an hour is roughly $125 around here. If you want to actually use the license...
Still, it's not like I'm trying to buy a Lamborghini or join the country club, I guess it's all a matter of perspective...
