40 year old IFR helicopter with no auto-pilot, no electronic displays, no nothing, just a weather radar and a single GPS. More-over, the float bottle might have no gas in it, the engines might be on extension 100 hours past TBO, the liferafts might be time-ex, and the windscreen wipers don't work especially when it's bucketing down in a tropical thunderstorm for 5 months of the year.
YOU''re are getting paid to make the decision to 'go' or 'no go' with this aircraft.
To make this decision is part of your job.
This decision is a big hole in the swiss cheese.
YOU MUPPET.
If the world comes to bite you in the ass, due to you not being able to see out of the windscreen, and you end up in the water with no floats or liferaft, YOU and YOU alone will have some explaining to do. - to your passengers' families, and your employer.
I think neither of the above would wish you to be doing what you are doing.
Please consider a change of career.
