Hi! I had encountered several difficulties while trying to land my Singapore Airlines B747 plane at SYD runway 34L(ILS 34L approach). Firstly, I was a bit confused when the ATC instructed me to turn left heading 005(to face the runway) and maintain 4000 ft until I have established the localiser .At this point in time,my plane was about less than 25Nm from the airport and flying at 2300ft . I attempted to establish the localiser by keying 110.10MHz and switching Nav1 on . I also adjusted the heading to 335 and switched the Nav hold button on and the heading hold button off.However, the localizer did not respond at all .
On my second attempt, I decided to adhere to ATC instructions and engage the localizer at 4000ft and at 25Nm from the airport . My plane was facing in the direction of SYD international while I engaged the localizer .Similarly , my efforts were futile .The specific ATC instructions were "Boeing SPQ, you are 31 miles south.Turn left heading 005 .Descend and maintain 4000. Cleared ILS 34L approach . Maintain 4000 until established on the localizer . Contact Sydney Tower on 124.70."
Isn't 4000 ft a little too high ? What is the appropiate method to resolve this issue?
Thank you for your advice .
P.s . ILS landings have always been bugging me so I am pretty frustrated over poor landings .
