You really do have your ‘try to embarrass LB at every opportunity’ hat on too tight sometimes.
Don't need to wear that hat LB as you seem to be perfectly capable of embarrassing yourself over your obsession with reading back the QNH.
If you don't understand the readback requirements of section g of AIP GEN 3.4 then no one can help you. If you don't comprehend why you aren't given the QNH on departure when you are required to state the altitude you are passing then no one can help you. If you can't discern why the QNH on an ATIS is the only bit of information that can kill you if you have written the incorrect numbers then no one here can help you. Like I said don't go flying in NZ if you want to keep your sanity. Incorrect QNH settings continue to be a problem on two crew airliners when the ATIS is printed out so why do you think that you will never make a similar mistake as a single pilot?
