Reminds me of a Grumman maintainence manual for the F8F Bearcat. It refered
to the landing gear as "alighting gear."

But did the lights go on/off when the gear went up/down? ;-)

Augmentor is another word that jet engine manufacturers use for afterburner.
GE also uses the term "augmentor" on their engineering lists.
Essentially, the afterburner increases the power of the engine. The engine
will work fine if the afterburner was not attached. Only military planes have
afterburners attached. Commercial aircraft do not have afterburners. That was
how it was explained to me by an old AF jet engine mechanic and former GE
employee.

into or departed MIA.
Think the names are shuffled by pedantic snobs. British used to (?) call
it reheat. (Additional fuel sprayed in behind turbine wheel to 'reheat'
unburned air (about 80% of gas stream) to get more thrust. Increases
thrust about 50%; total fuel flow about 4-5 times(!)
Pilots call it AB.
Great sound, great feeling when engaged.

Specific examples: the two engines for which I have SFC figures for both
augmented and non-augmented thrust are the EJ200 (EF2000) and the
RD-33 (MIG-29).
EJ200 - 1.5x thrust @ 3.2x fuel usage
RD-33 - 1.6x thrust @ 4.3x fuel usage
Interesting, huh?

-Doesnt Concord have re-heat ( or afterburner)?

Well for the most part....Concord has four very large afterburners!
(although as a Brit i suppose i am meant to refer to it as "reheat!")
