Re: Campbell's even crazier than a MANIAC? (archeopteryx climbing)



More generally regarding powered flyers and gliding .... if their minimum 
energy output to maintain level powered flight is X watts, then when it is not 
powering its flight(flapping, a propellor, etc), those X watts are coming from 
a change in potential energy, ie delta h (height in: PE = mgh).
The more energy intensive the flying must be, the faster it will sink while 
gliding, but it can still glide.
