When I go to the nav lsk on the cdu sometimes the ils frequency is set to park. How do I enter the ILS freq manually. Entering the freq and hitting the lsk beside the park notation gives me an "invaled entry"

go to your nav page   enter  the ils freq  and course  and the bottom of  the cdu   than line  select  it  to the above  slot

Notation should be:

 

mmm.kk/ccc

 

Don't leave out the zeros!

I did that and get invalid entry! I stated that in my post. If there is PARK in the ils freq, you cannot change it!

 

 

Ollie, your post makes no sense to me!

Example: Your ILS frequency is 109.50 and the course is 6°:

 

Wrong: 109.5/6

Also wrong: 109.5/006

Still wrong: 109.50/6

 

Correct: 109.50/006

did that and get invalid entry! I stated that in my post. If there is PARK in the ils freq, you cannot change it!

 

Did  you actually selected  the arrival details in the cdu  since if  you  don't  you get  the park option

 

 

I did that and get invalid entry! I stated that in my post. If there is PARK in the ils freq, you cannot change it!

 

Not true. Did it last night.

 

As Olli mentioned, you need to enter the full frequency and full course:

111.90/088

 

Do not leave the zeros out.

Also, there is no need to change PARK manually.

 

PARK should automatically change to Autotuning (A) when an approach has been selected and:

- less than 50nm from top of descend, or

- less than 150nm from rwy threshold, or

- FMC in descend mode

 

If the frequency or cource is wrong, then you can enter it manually as described by others.
