...dirt cheap...just a lil 'ol AM transmitter...and no maintenance at all. They'll run for ever if they're solid state and never even require re-tuning.Try flying in northern Manitoba and/or the arctic and you'll see the benefit of having an NDB! Sure they aren't at all as amazing as GPS but they are cheap and relatively low maintenance.
why would anyone want to get rid of them when there are some places in Canada where it's the only navigation aid that works?
...it's exactly the same technology as VOR/ILS, Communications, GPS, Cell phones, Sat-Com. It's all wireless technology. We just process the signals differently. (+/- 3 degrees accuracy)Why are we still using these things? Isn't it time for them to go the way of the dinosaur?
If your ADF is not acurrate it's not the entire systems fault. Your ADF is not working to spec. Unfortunately there aren't a lot of good ADF techs anymore.
I remember troubleshooting and ADF system onboard an AC aircraft years ago and an Avionics Technician from said airline did not know the functional difference between the sense antenna and the loop antenna. 23 years on the job he was then...ugh.
I've flown many times with very good pilots shooting an ADF approach at an airport with no ILS and it was bang on every time.
...and hard pressed to find an American household without a loaded handgun in it somewhere...should we follow their lead on that too?You'd be hard pressed to find an ADF on the panel of a modern American aircraft.
I believe we're intelligent enough in Canada to make our own choices thank you.
so lads take off the blinders and realize that there is aviation outside of your local area with different circumstances and even rules --
