Depending on individual company policy, most airlines will continue to adopt SID as published, in line with the clearance given as long as they have GPS on primary mode, accuracy of their navs eqpt are high and the intended route is programed in FMS/FMGS. Not really a problem for modern day jetliners. Ground beacons are mainly used to crosscheck the computer onboard. However, this procedure may not be suitable with "classic" type of aircraft. In fact, some latest aircraft are not fitted with ADF at all. Does that mean non ADF equipped aircraft will not be able to depart from eg. Beijing rwy 18R? (RENOB departure - mainly use NDB for initial outbound tracking). This may not be the case.
Therefore, with or without VOR/DME/NDB, one can still fly normal SID as long as the aircraft is fully equipped with other 'serviceable' sensors and individual company policy allows that to be flown.
Hong Kong TMA is an example where RNAV departure is fully adopted although they still have procedures for non RNAV equipped aircraft.
I guess, Lumpur Delivery is doing a good job for giving radar departure instead of normal SID to all aircraft to cater for all generation jetliners and different SOPs adopted by different airlines when VKL is U/S.
I personally tend to like Hong Kong ATCers, they are very positive and flow controls are very smooth considering such a small airspace with more than 1000 (one thousand) dep and arr daily that they have to handle, excludes arr and dep MFM and SZX. May be KL ATCers could learn something from them. Just a thought ....
