Hi Ivor,
Please remember you were using a database which is around 6 years out of date and the installation of the updated one will correct the majority of any erroneous information you were previously showing. The RAF doesn't normally reuse hex codes but some foreign forces do.
43C1BF ZD948 isn't flying and is I believe at Bruntingthorpe to be broken up for spares so I am at a loss as to how you could be picking up its hex to report it as it has not been reallocated.
AE54CC, the 6 was a typo now corrected and please advise Graham he is wrong as it is 12-5759 not 11-5759 as he states and is shown on the attached photo
https://www.flickr.com/photos/kevin_bell_photography/16004925626/A lot of these military aircraft are added in to the database at an early stage of their existence and the known information may change. I use a well known and respected database as well as forums and websites such as military mode-s for tie up information and the information available can change frequently and tie ups may have been wrongly associated in the first place, possibly due to assumptions in sequences. This is especially apparent for foreign military aircraft which are only noted as being incorrect when the come to these shores. I have seen many a debate on such matters on the mode-s forum. Also I am only human and on occasion press the wrong button inputting the data like I did when entering the serial for AE54CC. Unless I am advised either through me picking the correction along the way up or through being advised on the forum it will stay in the database as is.
The database update request thread is not only for adding new aircraft to the database it is for advising corrections and I am happy to be so advised when necessary as has occurred on this occasion with the two noted above.
Regarding the route info for military flights. It is the same routine which is used for all flights. The system detects the take of and landing point and adds it to the database where the route is showing blank. This is ok for scheduled civil flights as they usually but not always fly the same route day in day out. Military, business and light aircraft use the same flight ID more than once but mostly fly different routes each time so the routine is not applicable to them but it cannot be on for some and off for others and once entered can only be manually changed. Before sending a report I go down it and delete the plainly wrong, irrelevant and pointless route information from these flights.
I can get Grahams contact details from mode-s forum but I am happy to be advised of new hex codes with no info and incorrect data and please feel free to advise on the database update thread.
It is not only new data which is added to the database each day but also amendments and deletions so it is important to regularly use the update facility to ensure the one you are using is as up to date as possible. The two above you have advised me on have been amended and you will note the changes on the Navdata update available tomorrow.
Please feel free to forward this reply to Graham and thank him for pointing out those 2 inconstancies.
