*“I'll bet even you veteran pilots don't know this juicy little tid-bit! When using phonetic terms, we laugh at folks who say 'Nine' instead of 'Niner'. But do you realize that properly spoken, the number '3' is pronounced 'TREE', and that the number '4' is pronounced 'FOW-er'? Also, ICAO procedures require the decimal point to be spoken as 'DECIMAL'! But how many of us have used 'POINT' time and time again, huh?!!!”*

1) Turn to a heading of “**220**”
