Wiggy , like it . DME and a the 3 X table works like magic . Stil ask kids on trial lessons if they know the 3 x table ... Most just give 'wot one mother [ a Teacher ] called a list ... 3, 6, 9, 12,.... One 7 yr old spouted out 1 x 3 = 3 , 2 x 3 = 6 etc. very quickly and easily ... Upped the bar ...
'Wot's 17 x 3 ? .mutter , mutter ..''51'' .
'' That's Brilliant lad , you can fly Jets '' !
If I had a pound for every time time we'd turned final at LHR at 17 nm out .. = 5100 '
