TCAS RA and Structural Overload
Regarding structural overload risks of TCAS/ACAS RA maneuvers :
Initial RA command requires 1500 ft/min climb/descent to be reached within 5 seconds with max pitch g-load of +1.25g or +0.75g. If subsequently more progressive RA action required 2500ft/min to be reached within 2.5sec with loads of +1.35g or +0.65g. Far away from limit load of +2.56g or -1.0g, if you follow the VS command correctly. On HUGS equipped aircraft TCAS/ACAS RA maneuvers more easy to follow since Fly-To-Box displayed on the combiner...
