Start and STAR is OK
When saying to TWR ready for TO must be really ready.
Cleared DCT KOK, check first estimated Heading inbound KOK, turn, after turn set KOK VOR/OBS and correct heading.
inbound KOK APP say&#039;s expect holding over KOK.
Prepare the holding and approaching KOK request to the Approach for confirmation.
TOD  7000 down to 3000 is 4000ft at 500 ft is 8 min. Request descent on time for your comfort.
Read map for correct approach procedure and correct use of nav aids as IMI for the 08 in EBOS + DME.
Flight was good and good understood but missing some structure and use of aids available on approach plate. This bring you in trouble.
