Hi, guys
I am a new pilot here, so i may ask many silly questions to you.
My situation is: When i land with ils Approach, in the middle of the approaching, the approach button will turn off automatically. At different airports, the situation different. For example, I can use approach all the way to land perfectly at jakatar airport. However, HK is the worst. when the aircraft adjusting heading, suddenly approach button off. After it comes back, i am so far from the runway heading already. My ils frequency is correct, NAV mode and runway heading ok. What is the problem? Can anyone help me? I am very frustrated for this.
Thanks for your help.
