its speed relative to the air through which it is flying.
Not necessarily. If there is a tail wind the air speed may be less than the ground speed.
your talking about IAS indicated air speed.
the actual aircraft speed is what I was talking about.
and the actual air speed would increase in a tailwind.
and I think I covered the guages and pressures already
in my reply.
I think you have that backwards Bill.
a tail wind would cause the aircraft to have a greater air speed , ( speed it up )
a head wind would cause the aircraft to have a lesser air speed ( slow it down )
in a tailwind mechanical instruments would show a lesser air speed
( because there is less air pressure acting on the speed sensor / measuring device )
but the actual air speed
( of the aircraft )
would increase.
I wasnt talking about IAS indicated air speed , because I
was talking about the actual aircraft speed in a tailwind.
air speed is the measurement of the aircraft speed.
ground speed represents the actual displacement of the aircraft at ground level.
air speed is always greater than ground speed.
try and find a situation where actual air speed is less than ground speed without flying through a hole in the earth.
as long as the aircraft is flying above the ground its air speed will always be greater than its ground speed.
even if it is flying straight down.
or straight up.
theres no way around it.
