Kapitan asked: By the way, do you navigate often with Doppler? or Ins? which do you prefer? Was the Doppler standard in 707s ? INS came later & only special 707's were fitted with these units. The domestic (non ocean crossing) planes used dual VOR's for just about all navigation. It was rare to even use the NDB in the U.S. except for LOM I.D. In Europe, there were more NDB legs, but those planes had DNS so that acted as a primary navigation system since the NDB's were a pain and on long legs to the south of the Mediterranean, NDB's were not very reliable and mostly pointed to thunderstorms.  :o With high altitude VOR's, you could fly long legs with out much effort.
