I took my PP EXAM at IVAO network last sunday i had a problem retaes to the NDB tunning and range. In the vecinity of Salamanca AirPort, examiner trole me to tune AL NDB and fly direct to it. I was 20 miles east of BBI VOR (established in R270 inbound), so in theory i had to have coberture from AL. But i hadn’t and had a no-go for that task. After that i resumed own navigation and a bit before E notify point the ADF began to recieve the signal.
Last night i flew a bit in Salamanca offline to test the issue. I found out that NDB sig al has 15 NM radius coberture with Navigraph AIRAC but 23,5 miles range without the dataset.
As far as im concerned, this is not s new topic (well new for me unfoetunatelly), but may i ask for any way to adress this issue?
Hi,
please is it possible that you give us more details about the airport, the ndb and the VOR
What is the airport ICAO code for this airport?
I have 3 BBI VORs in the database? Which one do you mean here?
I have 6 AL NDBs in the database? Which one do you mean here?
It´s a little difficult to look for the correct navaids with only an ident - at least a frequency or a name could be helpful.
In general, NDBs have three power ranges
Ultrahigh >= 200 Watts
High 50 - 1999 Watts
Medium 25 - 50
Low less than 25
Depending on the power we set following ranges:
Ultrahigh = 75 NM
High = 50 NM
Medium = 25 NM
Low = 15 NM
That´s the default values we set but we have seen with the extended ILS range, that the MSFS ignores this and use a default range, independent what we have set. The same can be happen here … but give me the details to this navaids and I will look deeper into it …
Thanks a lot for your reply. So default range is wrong, i supone. I had problems also with SAK VOR following R722 beteeen SAK and CSD NDBs but cant tell you te range of signaling. I thought it was a simulator issue before reading about range problems with the AIRAC. But, if this AIRAC dataset is correct, it means that i’ll have to deal with en route navaids with GPS.
