Pace,

I appreciate your experience with the Seneca, may I ask you to do the calculations for the journey and publish your findings here - we all know that the flight failed, but it would be good to see the calculations done by a pilot such as you with as much experience on type.

The route filed by Weaver was CYYR-LOACH-59N50W-DIRECT (BGBW)

The Weather was forcast as: (quoted from official accident report)

The following weather forecasts were issued by the meteorological office in Kangarlussuaq (BGSF) Greenland the
14. April 2008 were available to the commander:

Peter,

The Seneca is burning about 20US gallons per hour at 13,000ft with the engines leaned, it takes about 20gallons to get upto 13,000ft from engine start, taxi and climb.

I was hoping to be in Iceland later today, please see the below weather report and the winds, this was unexpected to be as bad as this, and sadly as you know its not cheap being grounded in Goose, I hope to be airborne again tomorrow. (Note Greenland is closed Sunday so I want to get to Iceland tommorow to avoid further costs to you/your client)

Routing will now be CYYR Direct BGGH to save time and money for both of us. (700nm in distance)

I have net access at the overpriced hotel so please feel free to drop me a e-mail back, note that I have no cell phone signal.

The trip up yesterday was more or less IFR all the way shortly after leaving KLEW with the ceilings at 14,000ft down to about 5,000ft with moderate icing and turbulence, but nothing of a problem.

Hope to hear from you later,

Rob
