Transatlantic Air Routes

[leebrisco1]

Hi guys,

I'm a geography student trying to slowly get through his dissertation. I'm doing it on "The effects of a hypothetical eruption of Katla, Iceland, on transatlantic air routes".

I'm up to scratch with the volcanology side of things, but transatlantic air routes are problematic.

So far I've identified three main types:
1. OTS Routes
2. SST Routes
3. PTS Routes

Any idea where I would get the routing information so I can plot these?
I'm aware the OTS routes are updated twice daily and the SST & PTS routes are permanent.

Cheers for your help.

This should help.

You are correct in stating The OTS routes change from day to day to take into account of meteorological conditions (including VA) and tha PTS routes are fixed. But even the flexible OTS have common portions which are generally fixed and there is also the 'Blue Spruce Routes" which are also fixed and for aircraft which can't meet the Minimum Navigation Performance Specifications (MNPS). The manual should explain all.

The SST routes are a bit redundant since the last supersonic airliner had been retired!

Cheers, that gives me the routing information for SST and PTS Routes.

I've been checking out the Shanwick and Gander websites for OTS routes - so far no luck

You could at least have given him a link to the CURRENT VERSION
