It’s taken this newbie two months to realise that I have more or less hit the limit of my current site
in terms of rising up the ranks (without spending further £££, conscious of law of diminishing returns)!
I’ve been tuning with the aid of the graphs1090 and according to the data I see a lot of “positions” (typically around 20 million over 30-days) and message rate is quite encouraging, but I get nowhere near as many aircraft counted as I would have imagined. My gain is set appropriately not to loose too many nearby aircraft due to proximity of the RAF base at Brize Norton and the (mainly light) aircraft out of Cotswold Airport (on fine days).
Am I correct in my assumption that an aircraft is counted only if it is a unique Ident per day?
I only ask because sometimes I see aircraft (such as C17, C30J & C130) out of Brize Norton, often “practicing” and the local sky can feel busy with traffic circling, but my aircraft count sadly refuses to increase as much as I would have imagined
Example: I see Ident RR818 flying and completing its flight. Then same Ident flying later in the day. So should that Ident count 1 only for the day or would it be fairer if it counted 1 for each flight (there may be several) on that day?
Analysis of the tracklog data would no doubt discriminate between the separate flights.
Just a thought!
For commercial flights, would one ever expect to see the same Ident re-used within a day?
I’m thinking primarily of the short regional hops that the same aircraft may be able to complete/repeat quickly. Perhaps that’s deliberately planned / scheduled to avoid any possibility of ambiguity of flight Ident?
