Will you be instructing us in pathology soon? (I hope I got your
specialty correct) :-)

Thanks, Chris, I understand. It never ceases to amaze what I learn on this
List. We should start a JOAT credit program (jack of all trades).

American pilots call it “mil” power, Charlie: it’s maximum power before
you light the afterburner. The throttle quadrant is split into 3 or 4
parts: HP cock off (engine shut down), idle to max dry (mil) and minimum to
maximum afterburner or reheat. The Tornado has a 4th sector called Combat
power.
In the dry power section the conventional part of the jet engine functions
with the efflux providing thrust. But there is plenty of oxygen in the
efflux and that is used for afterburner (“after” meaning at the back rather
than later) in which guttering in the efflux sprays fuel which is lit to
provide quite a bit more thrust. Modern engines double the thrust with
afterburner, but it uses much more fuel. The EJ200 in the Typhoon has a
massive amount of dry thrust, capable of pushing the aircraft supersonic
(“super cruise”).

What does that term mean, Chris, under "dry power"? That is unfamiliar to
me.

That’s a kind and comforting thought, Ian.
I worked on the Eurofighter programme in the mid-90s and there were many
challenges to making the platform a success. But after being shown
around
the machine (for the first time ever) by a young pilot, just out of the
conversion unit, I’m convinced that it’s a smashing and highly effective
multi-role fighter. It’s the first RAF fighter, that I know of, that
can
takeoff safely in dry power (“mil”). I watched them do so before
climbing
at very impressive angles.
I saw one display at RIAT several years ago, but he very nearly died
when
he performed a low-speed gear down barrel roll at low level. Only the
stupendous engines got him away from the ground safely.

lot from your experience.
Saw one of those displaying at Southport last Saturday. Pretty
impressive
for height-limited display (it was rather murky).
