AC43.13-1A/2A Page 165-1 figure 10.1-Tube data makes reference to torque values when tightening AN818 nuts on both aluminum alloy tubing and steel tubing.

In the real world, when you can't get a torque wrench into a tight space to deal with hydraulic lines, what is an acceptable alternative? Install the nut hand tight and then tighten using a wrench one or two flats more? How about when installing steel hose fittings onto aluminum bulkhead fittings?

Thanks in advance...
