Hi Richard

That pretty well clears it up .....

I assume you can never also remove 100 feet from special minima (shaded boxes and actual QNH known)

Hi guys

I need clarification on an exercise from current IREX book.
Page 3.20 Example 2

My understanding is that an ALTERNATE "IS" required as Quilpie does not have an NDB. It has only RNAV published approaches. .... am I correct in thinking this way ....

Also
Page 3.24 Q4

Answer says that VIS is OK as not less than 8km ... can't see anywhere in the ARFOR where this is stated (is 5km in SH/RA). I understand that the SH and TS are NOT a problem for the ETA, therefore do you ASSUME 9999 VIS otherwise ... please clarify ..

Regards
David

I think you will find that AIP GEN 3.5 para 3.6.4 clears that up. 5000m in showers does not mean that the vis is 5000m throughout the entire area. It means it is 5000m in the showers. If you are not in the showers and there is no mention of any other visibility restriction, it is 9999.

Regarding Quilpie NDB, they obviously have decommissioned it since that question was written. I'll have to change that. Thanks for the feedback.

Hi Bob

Thanks for that ...
Thought the 9999 was the case .... as I did realise that the VIS 5000 was not an issue for the ETA.

Exam next Tuesday (9/8) ... had to put it off for a week ... brother serious ill in ICU.

Will let you know how I go ....

David

Hope all is well with your brother. Good luck with the exam. August 9th is the anniversary of the bombing of Nagasaki - is that a good omen?

Another one ....

IREX Book Page 8.1 Question 5 --> How do you get (d) as an answer
(I can't find the references stated)

Also ...

IREX Book Page 3.3 Question 3
I assume we can ignore the 35knot gusts if we choose to use Runway 25
(even though all approaches are for 18/36)

Regarding Question 5 Page 8.1. para 57.2.1 is now 58.2.1 The question states that it is a VFR arrival and you are within 30 minutes of the commencement of INTER 3000m and BKN008.

I can't find any Question 3 on page 3.3.

Hi Bob

Yeh ..... this is how tired I'm getting ... didn't realise that the YCAS TAF was further up the page ...

I meant for the other question ..... should have been Page 3.33 Q 3.

IREX Book Page 3.33 Question 3
I assume we can ignore the 35knot gusts if we choose to use Runway 25
(even though all approaches are for 18/36)

Can you quickly verify ... regards

The wind is from 260°T and the runway is 250°M, so the wind is almost straight down the runway. The wind to be considered in alternate planning is the cross wind component, not the speed of the wind alone. This is a strong wind, but it has virtually no cross wind component on that runway. You don't necessarily have to land on the runway related to the approach. You can do a circling approach and land on any usable runway.

great ... just what I needed to know .. wasn;t sure about the change of runway ... BUT, as you've said .... you've got a golf bag full of clubs ... use what's best ..
