I know some SOP’s require it but I’d rather skip the ground test and rather rely on previous crews report of it’s functional status.
WTF? do I assume you would suggest there is no point checking the mags before take off because they may not be serviceable later?
I would suggest if you are operating around the Central Pacific, no HF, no go. So a pre take off HF check is essential. SELCAL however is a luxury.
