situational awareness - conflicting information
Hadn't really experienced it till the other day - VOR/DME approach into an airfield in Turkey with lots of terrain and broken cloud close-ish to a high minimum. Both VOR receivers were tuned to the airfield beacon when, at approx 7 miles out the Captain's DME reading was still counting down as normal, while mine started increasing - within about 10 secs got to a reading of 10 miles. Then we started to wonder if we really knew where we were. Considered going around but then went visual. Not an altogether comfortable experience while it lasted.
Might be something to get people thinking about... What do you do if the information isn't consistent?
