Hi there - there is a long history of various inertial navigation systems from Litton from very early
mechanical ones until recent ones based on laser gyros and GPS fusion. Recently I obtained a
LTN-72RH made by Litton Aeroproducts, Canada; part number 1520°0-05-02-36-71, serial 2836:
This unit obviously is of the latest generation using mechanical gyros on a gimbaled platform...
...together with a digital computer for navigation and user interaction. I have essentially three
questions on this unit and I am sure lot of experts and/or users should be in this forum:
(1) Does anyone know,
where this LTN-72RH was used - I have been told, it was on DC10-300,
but not sure on this. Also would be interesting,
what the additional letters "RH" mean - probably
some radio-nav addon included (Software revision is 72-71-06)?
(2) Of course: Any
manual/schematics/pin-outs around helping me to better understand or even
fire up this unit? BTW: I have some experience in making equipment like this work again ;-) -
see my
work on a
or an
(3)
Which CDU does match the unit? From the WEB I know a very old type of CDU as used with
LTN-51 (Concorde and probably many others)...
Than there is a midle aged CDU which obviously already has alphanumeric displays:
And I came accross rather modern CDUs by Litton which more look like a FMS:
Any hints/discussion/comments are welcome...
