To be fair, Retired BA/BY led with the 105mm howitzer rather than the mini gun when he said this: "Yes but says little for the flight crew.".
There is a wealth of experience on this forum and when shared, we can learn through the benifits of others experience, without going through the pain ourselves.
BUT, aviation changes ( and I appreciate not always for the better) so I think it can be useful for those now detached from the industry to research current practice before pointing the 105 at their feet.
