Other than using TIGERs for an off-load SID, they are really useful if there is a strong southerly wind, 'cause the left turn off 26L allows the BIG sector controller(120.52) get some altitude on the departure and the turn is under better control turning into the wind. Bearing in mind that you've got to get above the BIG hold and be level FL130 by the extended LL centre line, or alternatively, stay at 6A under BIG & LAM, anything that gets the climb rate increasing is a useful tool to have.
BA KK can we have the "very good rate available" 737s back on the LAM deps instead of the RJs/146s..........please!!
