Christ on a bike how hard is it to dial 121.5 and say the words "Pan Pan Pan I am lost"?!?!
You DON'T need to practice that! Its only speaking out loud!
What you are doing by cluttering up 121.5 is making hundreds of airliner pilots who can hear you from 250 mile radius reach down and deselect Guard. It can then be some time, if ever, before they return to monitor the frequency. Which can and does result in armed fighters being scrambled at the speed of heat into controlled and busy airspace.
I've no obejection to GA on 121.5 if they are Lost. You are not slightly unsure of your position, you are not confirming where you think you are. You are in fact unable to tell me with 100% confidence that that town is Bishops Stortford and that your aircraft is exactly here on the map. You are therefore LOST.
Its no shameful thing - heck I've been more lost and more scared about it than any of you on this thread. I've used 121.5 thousands of times for training and for really real. I've made two Pan calls in the last 10 weeks.
But I object to it being abused and cluttered up by people who are in fact lying. Get a LARS, learn to use the navaids or buy a GPS.
