So let me first explain MY existing/using/allowing approach procedures:
- 1) Vectoring manually by hdg+alt+speed for pilots not able to use ILS/VOR (hoping that the pilot can hold those hdg+alt+speed!) --> most Time-Consuming[]
2) Guiding pilots via VOR/ILS --> and watching closely
3) Using SID/STARs (on request)
3a) You may have noticed that I mostly e.g. ask to use the SID KERAX-2 (guiding to rw25R) also for landings on rw25L (which is our standard!) - and similar! One of the problems why we cannot always use the standard approaches -> because 25R is only for small/medium jets (e.g. A320 etc). I know I will be jailed if any accident happens because of that! Still I will continue doing so - i.e. just advising e.g. an approach from MTR to land on 25L and reverse form CHA ontu 25R (if the area is crowded and both runways used!). Makes life much easier for an overloaded ATC!
3b) Also you may have noticed that I use 25C only for STARTS - but assign routs that are for rw25L/R. Again: That makes life much easier for ATC!!
4) This mix in 3 makes it difficult to use ILS-Yanky and similar. I want to keep control about what runway to use for final! But it would be ok if you ask after pasing last VOR for using it (e.g. "may I use ..... for rw 25xxx!"). But only after you have passed the last VOR and identified for what RW (I do not want to search in big books which runway that procedure is! --> Exactly that is the most critical/overload time for an ATC! - but what pilot cares about how much an ATC needs to know all the time (be aware: In the real EDDF they have 1 unique ATC for each runway and another for Approach and Area!!!)
5) Using the "holding patterns" on different altitudes. Also an exception from standard (I guess I had used that during the last 2 years 2 times!). Mostly I rather delay a plane by defining manually a longer Approach --> most pilots are not able to fly a "holding pattern")
From my side my biggest wish from you: Pls suggest to everyone to use MUMBLE [/b] (http://www.emmerich-j.de/mumble/mumble.html) - I guess that would help us all mostly in any of those mixed cases - and in the ability to use more different procedures!!
