Update of INS
A few questions, please feel free to answer any or all.
1. How close to a VOR/DME do you need to get for an automatic update?
2. I understand INS will update within the range of two DME within 200nm of each other subject to a restriction on the angle between them, is this right, or are there additional restrictions?
3. How about manual?
4. Does updating happen more or less continuously, if the conditions are right? (Other than immediately after departure after a ground alignment.)
5. Do you get an indication when the machine is updated?
6. Do you get some sort of indication of the time since your last update.
