Exactly – it is technically possible but if your forecast is wrong, the tailwind goes away and you are between Greenland and Canada, you have a big problem.
No worse than if a headwind is stronger than forecast.

Or course but this why you dont fly tight fuel legs over the water.
Also prudent planning ignores tailwind but doesn’t ignore headwind, so the safety angle is slanted towards the headwind scenario.

Well, we were discussing whether I could make Iceland without a tailwind from Goose.
When you say prudent planning it depends. If flying around Europe or the US and looking to make a max range flight you can include the tailwind so long as you have options to divert if things change. For example KBTV to KMCO Sunday was the second longest leg I have done in the plane (1073nm flown – longest was 1183). It was very dependent on the wind forecast but in the US you have an airport every 5nm so if the wind changed you have options.
Canada to Iceland you could divert into BGBW but weather a big risk there. Your worse case is being between Iceland and Greenland and losing the tailwind.
With a 100kt tailwind it is doable. But in practice you are likely to not get the altitude you need so it wouldn’t work.

Wasn’t it both piston and turbine PA46 variants ?

As Narsarsuaq is a “day only” airfield with frequently poor weather and high minima on the IAP the window of opportunity is quite small
Do you have HF? Is the Mustang Cat 1 only?
I was just reading Mark Alberys report. He did the reverse trip in his VANS RV8.
Always good fun to see Andy Bruce at Wick.

Yep. I wouldn’t recommend it.
You can go into BGBW at any time – but if out of hours you’ll pay an additional $1000 opening fee.
Easy alternative to the IAP is to simply let down over the sea and then enter up the fjord low level. Arguably safer as well!
