vor
hi,
i have the following doubts on vor, any help would be appreciated.:
1. whats the difference between site error and propagation error?
2. accuracy of VOR is required to be +/-5degrees 95% of the time, then why do we have an index of 4degrees for the VOT (test vor) ?
3. does VOR not suffer from quandrantal error like the ADF?
4. does the failure warning flag come up when a/c is outside the coverage range?
kindly post explanations too.
thanks.
