Always grin when the old chestnut of GPS inaccuracy/reliability raises it head.......The ADF is infamous in it's inaccuracy, even to the extent of being a prime question in the exams. The ADF relies on one transmitter (with no back-up), whilst we are all aware of the numerous sources for the GPS.
After spealing out the pneumonic for all the errors, had to scratch my head and wonder why we still used the thing, procedurally.
When will people latch on to the fact that, apart from the pilot, the ADF is the most inaccurate and unreliable direction aid in the aircraft?
It is also just as easily 'jammed' as the weaker sat signals.
Sounds to me that anyone who still extolls the virtues of the ADF (apart from getting the cricket scores) also hails from the same cadre of drivers who insist on the push-pull method of steering a car!! (OK, so I get the Telegraph, doesn't make me a bad person)
