2 NDB.
Hello everyone! Just a simple question for you! 2 NDB on approach chart and Std mnms. What does it mean? As I understand it means that both NDBs must be operative(i.e. no NOTAMS inop status) , another opinion that we have to have 2 onboard ADFs to work with both NDBs simultaneously. As an example, on some A320s it's possible to tune only one NDB at one moment. Thanx.
