 |
|
This is a question for the pilots and tech gurus. How does a PAPI or VASI function, I mean how useful is it in terms of guiding the aircraft all the way to its touchdown?
Regards,

yes, they are helpful, but you don't need to them.
one can easily land an airplane without the use of these aids ... all you need to do is pick out an aiming point some where on the run way ... aim for the point ... pitch for the point and use the throttle to maintain airpseed. when the point goes beneath the nose ... just round out, and flare and land ...
i've landed at a couple of airports without a PAPI or a VASI and this method works just fine ... |

i use power to control the rate of descent and pitch to control my airspeed - which happens to work for me.
granted every pilot has their own way of doing things. |

You might not need them if you're doing a precision approach or if the sun is shining bright.
If it's dark with no terrain features to speak off, a VASI or PAPI is really helpful. Yes you don’t need them as such, but something as simple as that can help out immensely in some instances.

That’s what we're taught as well.

I have never flown a Diamond aircraft. My university is getting the DA42 to replace the PA44 (Piper Seminole) but sadly I wont fly em.
What’s the difference between a DA 20 and DA 40 (fixed pitch, G1000?) Do you fly different planes when you’re shooting for different ratings or how does that work?

hey man, me just a PPL, working towards a ME-IR CPL ...
so the DA 20's a fixed pitch, 2 seater ... the DA 40's a 4 seater, variable pitch, G1000 ... thats what i'm doing my IR training on. and after this will be moving onto the DA 42 for the ME-IR ...

Good luck..
In my opinion it’s the hardest course- but it can be fun sometimes 
A bunch of my friends said they loved it, personally I enjoyed my private and commercial multi courses the best.

Even my friend Aravanth (who's also a member here on ai-ind.net) is there at Sabena, and he too has been selected for the Spicejet Cadet Program. Wonder if you know him ?
In the meanwhile, i am slogging on at accumulating the funds to finance my dream of flying. |
haha, yeah know aravinth very well. he's doing really well in his flying ... both of us were in the same batch while doing ground school in gurgaon.
which school you planning on heading to? |

here we go again! 
he says Aravinth is topping the class..then in a short time Aravinth says that Nikhil is topping the class!
actuall both of em are doing very well and giving their instructors a tough time! 
btw tell us your experiences on the diamonds....
they look pretty sleek!

hahaha, mr. 007 is funny! 
well the DA 20, is a nice a/c, easy to fly, BUT ... the engine's don't like the hot weather here in arizona ... it's fuel injected ... and we get a lot of vapour locks etc. plus if you take off in the afternoon and start climbing ... after a couple of thousand feet you see the oil pressure dropping below green and the oil temperature rising above the green arc ... engine shuddering etc ... the one cool thing about it DA 20 is that it has an altitude compensating fuel pump. so you don't need to worry about leaning the mixture as you climb.
i've started with my IR training on the DA 40 ... and well, that's one cool a/c ... G1000 and nice lycoming 180 HP ... no problems what so ever ... did a VOR approach day before yesterday and a GPS approach yesterday ... and a lot of holding patterns! still getting a hang of the plane ... coz now i have a throttle, prop rpm and the mixture to play with
got a basic instrument check coming up next week, so wish me luck!  |
