Hypothetical Question from my Instructor. HELP!
 
EDIT: My question has been answered. Thank you to everyone who gave me hints and advice and didn't just flat out give me the answer. In the end I did figure it out myself with alot of help from the hints I received on here, although to be honest I was quite confused about the whole thing for a while. At least I understand the concept now!

To everyone else that just seemed to want to hate on my instructor or hate on the question he asked, I think you guys really need to gain some sort of a life. You automatically took judgement to someone you don't even know. I have learnt that in the future not to post questions of this nature on PPRUNE.

I will however continue to observe and post the odd post on here however this will be the last time I ask a question of any nature.

Happy Flying everybody! Be positive! And thank you.

I won't answer it for you, but have a think about what effect w/v has on TAS and Track. I think your instructor has thrown in a good red herring for you.

cac_sabre 19th Sep 2012 00:41

060 or 300
 
all crosswind vector for the aeroplane? probably totally wrong..

b_sta 19th Sep 2012 01:06

Think about how to get the maximum difference in groundspeed between the plane vs the clouds.

Push the nose to vertical (downwards) and hope you can pull out in time :E

Skim the tops VFR , Bloody dangerous and illegal, Instructor should know better even if it is Hypothetical

Elfatness 19th Sep 2012 02:16

thanks for all your answers so far! I am currently doing a fair bit of brain racking :)

I'll get back to you guys as to how I go!

PS: Im a real freshy!! a whooping 32 hours in the logbook!! ;) So I really do appreciate you all giving me the time of day :)

Elfatness 19th Sep 2012 02:28

I did already bring that up with him T28D... haha ;)

Tell him a low centered over Kangaroo Island is bringing a water laden airmass down from the north causing the geo-stationary orographically lifted cloud layer, so therefore a southerly heading will achieve the desired effect.

*Lancer* 19th Sep 2012 03:13

You're both in the same airmass = doesn't matter which direction you fly.

Elfatness 19th Sep 2012 03:13

ok im still struggling to work it out :( I think im more stupid than even I realised!

AerocatS2A 19th Sep 2012 03:21

The answer has been given at least once in this thread. Think about what airspeed means and what you travelling through.

ForkTailedDrKiller 19th Sep 2012 03:22

Have a look at the rules for VFR flight!

I have attempted to answer it twice and failed
I'm guessing these were "into the headwind" and "with the tailwind"? What other options are left? The answer is a few posts above.


Bloody dangerous and illegal
Dangerous, yes! Illegal? No. VMC (class G) below 3000ft means you simply need to be clear of cloud. I guess it depends how high the cloud tops were in the instructor's question...and that they are in non-controlled airspace and not a GAAP, I mean, Class D airspace.

To be honest though, the instructor is just pulling his own wang indulging in his self-importance by keeping the student guessing. Bloody three-bared rock star.

VH-XXX 19th Sep 2012 03:56

In his defence he did say hypothetical.

Your intructor is just trying to trick you. It doesn't matter which direction in which you fly, it will be the same.

That being said, often the wind just above the clouds can vary significantly to under them, so in theory, it may actually matter which direction you are travelling in.... but you would have no way of knowing that until you got up there.

Elfatness 19th Sep 2012 04:05

Just to clarify Aimpoint, he is a great instructor and a top bloke :)

And to everyone else, thank you for all you assistance :)

If it takes a yard and a half of calico to weave an eskimo's underpants, how long will it take a double-breasted cockroach to tapdance through a barrel of treacle?

Your instructor is playing games with you.
It doesn't matter which way you fly, you are moving in the same parcel of air as the cloud.

Is it an African or European cockroach?
