The Tornado one does sound more like an aircraft with a warload however, bearing in mind it hasn't got the punchiest engines going.

Edited to add at max tax off weight the F-15 gets a TWR of around 0.8.
High TWR is obviously useful for more than VTOL ops - but then this has started making me think about how Drag will affect that aspect of TWR :roll:
which of course is not so much of an issue when doing a brute-force lift off the deck/hang in the air... :think:

Wondering if this is needing to go onto a new thread anyone.....? :worried:

Thinking out aloud again, I wonder if a graph of some sort could be made up giving TWR performance to altitude? (I'm thinking lines from the ground up showing what angle a TWR gives to move a given load at a given speed to a given altitude?) - Unless I am totally wrong (which is not uncommon) this should show up just like a graph?
