Kapooley,
Here are the answers to your questions:
1. This is a PSR calculation. First thing to do is to work out your Speed out and your speed home by using the windside of your CRP-5 using the given track for the speed out and the reciprocal for the speed home.
Speed out on 180 track is 212kts GS
Speed home on 360 track is 141kts GS
Then simply the equation is:
time x speed home
------------------------
speed out + speed home
= 1x141
-------- = 0.399 (time) x speed out to give distance = 85nms
212+141
2. This question is quite easy to answer as you may know that on a 3 degree glideslope the ROD = Ground Speed x 5, so imagine you're doing 100kts, which equals 500ft/min ROD. Then do the same taking into account your 10kt headwind (90x5), which is 450ft/min ROD so the rate of descent must decrease by 50ft/min to maintain the required 3 degree glide slope.

4. So that you understand this one better: Imagine the sun moves once round the earth every 24 hours. As there are 360 degrees around the earth, if you divide 360 by 24 this gives you the apparent movement of the sun per hour, which is 15 degrees/hr. Therefore, 5 hours 20 mins and 20 secs x 15 (5.338 x 15) equals 80 degrees and 5 minutes.
5. Careful on this one. It's saying 12% and not 12 degrees.
On the CRP-5 align the inner blue 10 with 12 on the outer. Then against the black 60 triange read 7.2, which is your degrees. Now align the black 60 triangle with your speed (540) and read off the 7.2 degrees glide slope on the inner and the outer is your required ROD = approx 6500ft/min. Rough way to make sure that you've got the right amount of zero's. 540x5=2700 (on a 3 degree glide slope) times by 2 and a bit to get it close to the 7.2 degrees, which is roughly 6210ft/min. This will save you ticking the box that says 650ft/min!

7. 45 degrees N/S. Don't try to understand it, just remember it!

I'll try and answer the other ones a bit later. It's just that I'm a bit short on time and they may take a bit of typing to explain. Just wanted to give you some help.
Good luck on Wednesday mate!!
