Speke softly
Maintain/ Continue. Thanks. I didn't know that one
I suspect they often get used 'one for the other'. Certainly I've been told to 'maintain' a heading loads of times.
Re 'Wilco' readbacks. If you are 'own nav' to somewhere and you are then given 'continue present heading' surely 'wilco' would do? I mean it's not an instruction to manoevre, merely an order not to. So I think 'Wilco' would do but if I'm wrong it wont be the first time.
As for saying outloud what the heading is. Well sometimes that's requested and sometimes it isn't. So are you saying that the hdg should always be reported even if its not been asked for? Shurely not!
What about my main point really which is about there being too much blah and not enough brevity.
(don't mind a bit of nit picking tho)
