a) 000; 000 with needle central and TO indicated
b) 090; 090 with needle central and FROM indicated
c) 000; 000 with needle central and FROM indicated
d) 090; 090 with needle central and TO indicated
Just cant visualize this one.
Q.2. The accuracy of a DME:
a) is approximately ±0.5nm
b) decreases with increase of range
c) increases with increase of altitude
d) is approximately ±2 nm
1) you are tracking away from the VOR, therefore have 000 at the top, with the needle centered and the From flag. It would be incorrect if it were tracking 000, with 180 on the VOR and a FROM flag, as you would be going to the VOR and indications would be in reverse sense.
2) the error decreases with range. If you are over the station at 6000' (1nm) the DME will read 1nm, even though you are at the station. At 50 miles, at 6000', the error will be far less.
