IMU's
RE: Will Fraser (#3739)
Will,
my reasoning was simply: the airplane has three ADIRU's, each containing an ADR and an IRU, what would it need an IMU for? (by the way, my understanding is that the IRU, as any INS, comprises laser-gyros and accelerometers for all three axes, it cannot derive speeds and position from gyros alone).
In addition, units like this in an airplane would have to be line-replaceable, easily accessible for maintenance, the pictures didn't looke like that.
