Hi

I have a little question regarding the way the INS was integrated to the 707 that I don't think either manual (CIVA or 707) could answer.
Last night I was flying a short Munich-Istanbul flight using the INS, and during the flight my INS alignment degraded to 94 as it is supposed to, however the plane continued to follow the flightplan flawlessly. At 94, I was expecting the INS to send me on a completely errouneous radial at the next waypoint change, but its being mis-aligned did not seem to affect the flight in any way.

Is the 707 CIVA integration disalignment-proof or does the CIVA INS simply not simulate disalignment induced drift ?

Cheers

Nico

PS : I think I might have made up a few words here, sorry about that, it's the best I could muster up at 4am :D
