VDP on non-prec approached

[bdy85]

What are some short cuts you all use to come up with VDP's for time and Distance.

Hope this is helpful...

Say your MDA is 550 feet and the local elevation is 150 feet. That leaves you 400 feet to descend.

Divide this number by 300 which gives you 1.3.
You should give yourself 1.3 NM from the runway to descend. Allow a 0.2 NM lead, so your VDP is 1.5 NM. Easy to figure out if on a VOR.

But say you are on a DME LOC for a 8,500 foot RWY (DME at far end of runway).
8.5 / 6 = 1.4 = runway distance in miles.
VDP for this is 1.4 + 1.5 = 2.9 NM

Then figure out VDP time for approach speed used.

...make the student do it

wow...I just realized I finally get to say "okay go preflight and I'll see ya in about 10 minutes"

^ totally irrulevant

thanx

either way, if you made the student do it YOU would also have to know how to do it to make sure he is right

I thought you were talking about me.

yep...I like the /300 thing...seems to me to be the easiest...there's one with time too...ah what is it

like...10% off of time from FAF-MAP?...I can never remember the time one...bad minitour...bad bad

You are a CFII? Sorry.

Primacy...I was taught the /300 thing...

hind sight, I would have made myself learn both at first....

it's an embarassment for sure, but I learn somthing every day...maybe tomorrow I'll learn the time thing...

yeah! That's it...

Godvek, you've inspired me to learn the time VDP thing tomorrow. If it takes me all day, I'll have it mezmorized by tomorrow night, or I'll buy you a cookie. Thanks!

Hey, when you figure it out, let me know, I forget.


I usually just use my VSI.

will do...thanks for the inspiration

But, hopefully, that's not how you do things. When my students go out to preflight, I go out with them. That's part of the training, no matter how many times they've done it. Most of the time we just BS while they preflight....but, occasionally, they come up with a question they probably wouldn't ask had I not been there.

yep...as I sit here and think about it, I kind of feel like a babysitter during preflight. Watching over their shoulder as they go through the checklist, checking fuel levels, oil, other things that could kill me...

Then I find myself asking questions like "what kind of flaps/ailerons do we have?" "what does this do?" "what is that?" "can you fly without this thingy?"

I guess that can be good, but I'm worried my stus are gonna start thinking "man he doesn't even trust me to do a preflight..." and get all depressive...hopefully not...

Honestly it's not that I don't trust them, just that I want to answer any questions they might have right then and there...I guess that isn't a bad thing...

...but the realization of being able to say "go preflight" after all this time is kinda cool ...in a nerdy kinda way...im such a dork
