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?

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 ...

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.

hahaha, mr. 007 is funny! Laughing

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 Smile

got a basic instrument check coming up next week, so wish me luck! Shocked

hmmm we don't have stages ... so not sure what stage 3 means Smile me on mission 48 right now ... mission 50 is a internal basic IR check ... then mission 62 is the internal IR check and 63 is the final FAA IR check ... each mission is 1.5 hours ... so that should give you some idea as to where i'm at ... our IR training started at mission 39 ... mission 38 was our FAA PPL check ...

so what does stage 3 mean? Smile

It differs from school to school. My instrument course had 2 stages; stage 1 was single engine, only holding/intercepting/non precision approaches. Stage 2 was multi + precissision + single engine stuff + everything else.

Good luck.... holding in the G1000 is (believe it or not) pretty easy. Heck I learned with an HSI and that was a big help. I did some flying later on with an old fashion VOR and it took me a while to get used to it Smile

thanks selecta!

commercial's not going anywhere ... flown once in the last 7 days ... just pathetic ... got a cross country time building stage in between. and then will start off with single engine commercial stuff and finally the multi engine commercial stuff ... there's a long long way to go!

but yeah, it's gonna be good fun trying to do a partial panel, single engine out approach in te DA 42! Very Happy

how's your flying coming along?

our program divides instrument into 4 stages, basic attitute, departure - holds, approaches, and then a grade ride.

i'm done with the first stage and i've got a checkride next week on holds.

so i'll be spending my free time this weekend studying. Confused

man, good luck with that!

how many turns do you do in a hold on average? we used to just do like one ... never used wind correction!

i doubt i've ever done more than 3 for a hold.

yeah i've had to do hold in 40 knot crosswinds - something that i hope i never have to do again. Laughing

we get pretty strong winds in the midwest - especially during late spring and mid fall (around this time of the year)

btw do you have a facebook account?
