Module 6 - Delamination in composites

[Billy No Mates]

What do you mean?

[Doc]

talking of the CAA, have you seen their latest piss take, a failed licence application now costs you £170....

Good. Will stop no-hopers who don't meet the minimum requirements trying their luck just in case and clogging up the system.

That's Billy's renewal screwed then.........

"Refunds – rejected or withdrawn applications
There have been a number of applications for the issue of an AML or for additional privileges to be added to an existing AML which have
been rejected by the CAA due to, for example, lack of experience criteria. This has resulted in the CAA refunding 100% of the application
charge even though time has been incurred to review the application in order to reach the rejection decision.
The CAA is required to recover its costs from those that have caused those costs to be incurred. Therefore, for applications received from 15
September 2016 the CAA will be deducting £170 to recover the average costs of its application review in respect of those applications that the
CAA has rejected or where the applicant has withdrawn his/her application before the CAA has completed its review.
This deduction will be associated with applications in respect of AML activities under the UK Official Record Series 5 No. 310 Personnel
Licensing Scheme of Charges para 13.1 Table 58 Refs a), c) i), d) and/or e). This action is in line with the CAA Charges Waiver and Refund
Policy dated 1 September 2016."

Reading through ORS5 No 310 it would appear they charge a man-hour rate of £170.

Not sure what planet they are on, but its certainly not this one....

......On the certificate pass or fail it has a section called 'knowledge deficiency report' which will list subsections of that module you got wrong.

This is true of NZCAA.
Helps people review the cheat sheets they pass on to their colleagues.
Romania has much to learn.

I will need help to make the connection.

Haven't heard of Romania in aviation since the Rom-BAC thingy ended.

This question is worded very badly..... However looking at the 3 possible answers I'd say:

The thicker the composite laminate the stronger it is - I'd expect to see the smallest delamination due to impact damage to a thick panel with the 3 answers available.

Because a composite panel is curved does not necessarily mean it has reduced damage tolerance in comparison to a flat panel, fuselage, wing leading edges etc - all just as strong as a flat composite laminate.

A thin panel however is the weakest of the 3 options, and an impact to the thin panel would cause the largest delamination.

Hope this helps.

No, Ian, it doesn't help. Because the original poster came back with the update from his exam in which option a) Curved was deemed correct.

I enjoyed reading through the thread, though.

The lesson learned here today was read all the posts before you comment!

Assuming it must be a large surface area impact that’s only making contact with a small area of the curved part then eh, not a very well worded question.

On the plus side if I now get asked this on module 6 exam I’ll get it correct, every cloud and all that!
