Re: Off the shelf

You are right to highlight the indecision and inertia shown by the RAF in getting TCAS. Ironic that they have been awarded a flight safety trophy! They should look more closely into what is available "off the shelf".
Would an "off the shelf" radar have helped in the Mull of Kintyre crash?
EESDL the Tucano aerobatics below the airway would set off the airliner's TCAS whether or not the Tucano had TCAS fitted. It would be the Tucano's squawk which alerted the airliner
