Take off in turn
 

Could any of you nice mil ATCOs out there answer the following -

I fly regularly from a mil. airfield. One common clearance on departure is 'Line up in turn...' 'Clear takeoff in turn...'

Is there any particular guidance on the spacing I need to leave, or is this basically up to me? Usually I'm in a Cherokee behind a Tutor, i.e. they climb at essentially the same speed (if not rate!)

No guidance... in fact the "T/O in turn" call must be covered by a local orders (for expedition) as it is not generally permitted by military ATC regulations.

The Controller would, I assume (hope?), only issue such a clearance to similar speed/weight a/c to avoid problems in the climb out with wake turbulence etc.

Yes, that figures - behind something heavier I usually get 'After the departing... caution rotor downwash' (it's usually that sort of heavier!)

Will check the base FOB, then, as it's probably in there somewhere.

When i was there I thought it was only a/c similiar type who could take off in turn , however a cherokee could land behind a tutor 'clear land one' on if controller assessed 1500ft/3000ft depending on student or not Reckon must be a change in FOB.

is slightly different in that it is covered by JSP552, although specific conditions required before issuing that clearance are defined in individual unit orders.
