IMC-ADF Tracking
Hello,
I`m currently about 3.5 hours into my IMC and doing it in a well equipped PA28.
The ADF in it is rotatable card type, but I`m being told that I must not touch it and must leave it pointing north all the times.
This is a pain...rotatable card is much beter,easier..we all know the score.
Is there any good reason for leaving it pointing north all the time? is it a requirement??
Cheers.
