Straight-In
Good work on ya mate.
Good airmanship is putting safety first. How many times must ATC's put up with these type of 'nuisance' requests when they are busy? You may consider that by you saving 20nm you win but have you ever considered that an ATC tries (with the resources available to him) to save each and every aircraft on frequency a mile or 2. By you jumping in and blocking valuable frequency time you are disrupting the ATC's thought process. Give the ATC's the time to do their job and you may end up scoring in the process.
Consider that there are others on frequency. Also consider that an ATC has to consider what is about to come on frequency i.e. pending departures and arrivals, what may sound like a quiet frequency one minute can explode the minute you are transferred to the next unit. In these scenarios the ATC is considering the safest options in order to get the job done.
Do not compare one airport or associated airspace with another. Procedures is what guides our industry. Yes Halifax may do things differently but you have to consider the resources available in order to make it happen, airport layout, local and national regulations and not to forget international SARPS.
Blocking the frequency with 'just normal business' is short sighted and naive. ATC do allow straight in approaches when the situation suits them not the pilot.
So in the end it is not really that simple.
Cheers.
