I think I must suffer from blackouts as I can not remember ever doing anything than a std dep from LGG , yes we do do the turn at 4.3 miles as per sid. You are correct though we do not do reduced pwr t/o,s it has been found that this is the most effective way of keeping the noise down on our a/c.The a/c does meet full stage 3 but as you should know with a lot of stage 3 a/c it does not mean you can just blast off willy nilly and not ring the bells, you have to carry out a proceedure ,change of flap setting and cutback of pwr ot 1000aal. you must also be good at your sid tracking . So these are the areas where you can get improvement from.
