Your common, every day IRS. i'm sure those of you who operate an aircraft using these handy little navigation aids all know what they do in some sense.
i remember a while back being taught what they are made up of, kind of. but as time has gone by i have taken this little wonders of aviation for granted.
i vaguely remember something about lasers, gyros, tilting mechanical tables or i'm i talking rubbish...?
i mean, i just know they do the job requierd but would like to know more.
replies appreciated and pardon my stupidity
