    Default RAF Form 1767 - Aircrew logbook

    Hi, I have my late fathers logbooks. From '60 to '65, he was a Nav Plotter on 44 Sqn flying Vulcans from Waddington. Can anyone expand on some of the abbrevations such as RBS and IRT?
    Thanks, Noel Cockfield

    Noel, Hi - welcome to the forum.
    I was at Wittering at about the same time. My memory is not what it was! Best I can do is:-
    RBS = Radar Bombing Sortie
    IRT = Instrument Rating Test

    Well, although I think RBS means Radar Bombing Sortie/Simulation, I'm certain that IRT means Instrument Rating Test.

    BTW, if your Dad was on 44 he must have known Dave Blackmore and his crew.

    I'm glad my hazy memory has not deserted me completely! Were the IRTs just one part of classifying the Captain of a V-Bomber? IIRC they were, Unrated, White Card, Green Card, and then Master Green. Unrated, White, and Green were allowed to land, etc, in accordance with strict limits. If those limits were exceeded then the a/c had to divert. A Master Green, I think, could make his own decisions?
    The Radar Bombing Sortie/Simulation was, I think, a bombing sortie with the radar turned on. There were also sorties (also called RBS?) during which the a/c radar was not turned on. The a/c had to position itself solely on astro-nav and met winds to the point of 'bomb release'. When the Navs agreed they were "there" the 'tit' was pressed and the imaginary bomb left the a/c. Its ballistic trajectory was known, so a small portable radar could tell if the a/c was in the right position for the 'bomb' to hit the 'target'. The NW corner of Barnsley railway station was a frequent 'target'!! Apparently, it's still there! The various V-bomber bombing competitions in 3 Group were fiercely fought. There was a lot of underhand skullduggery by Stations (and their Met Men) to give 'our' Sqns an advantage!

    68 Sqn,

    I've just called my world famous Vulcan navigator friend and he says he's never heard of Granny or Uncle!!

    Are we still in the Vulcan rea or are these terms which appear elsewhere?
