Narrative:

I was assigned to ground control (ground control). At apa; ground control controls the sequence for departures so all aircraft must remain on the ground control frequency and advise ground control when run up is complete for sequence to the runway. That is clearly stated on each and every ATIS when ground control is open. Aircraft X contacted me for taxi for departure and I said; 'runway 17L; taxi via alpha' and aircraft X read back the runway assignment and complied with my instruction. When aircraft X was run up complete; I informed him that he was number one; and to monitor tower and I believe he said he would comply. A little bit later; local control (local control) was amazed when picking up up the strip from the bay to clear the aircraft for take off; he/she noticed the aircraft was rolling down the runway approaching take off speed. Luckily there were no aircraft on the runway; crossing or on final. The pilot later apologized for the error because he now knows where he went wrong. At no time did I ever taxi the aircraft onto the runway or clear him to take off in addition; the pilot never gave me any indications that he was confused with my 7110.65 instructions. Recommendation; we have been having numerous issues of pilots crossing the hold bars and moving into position using apa's non-standard phraseology. It's almost to the point where we are just going to have to tell each aircraft to 'hold short' and then get the read back in order to get 100% compliance. The other thing we should consider is let the aircraft call local control directly for the sequence. They established this procedure when apa was working over 440;000 ops per year but we are working less than half of that now. New times require new directions or procedures. I still refuse to use th non-standard phraseology because I don't have time to explain to each and every pilot what they don't understand because this is not done at any other airport that I know of. We need a change quickly. This situation should just go down as just a simple pilot deviation but pilot deviations have become the norm at apa over the past 2 months.

Title: APA Controller described another runway incursion when the departing aircraft misunderstood local phraseology/procedures; the reporter seeking immediate changes to local procedures.

Narrative: I was assigned to Ground Control (GC). At APA; GC controls the sequence for departures so all aircraft must remain on the GC frequency and advise GC when run up is complete for sequence to the runway. That is clearly stated on each and every ATIS when GC is open. Aircraft X contacted me for taxi for departure and I said; 'Runway 17L; taxi via Alpha' and Aircraft X read back the runway assignment and complied with my instruction. When Aircraft X was run up complete; I informed him that he was number one; and to monitor Tower and I believe he said he would comply. A little bit later; Local Control (LC) was amazed when picking up up the strip from the bay to clear the aircraft for take off; he/she noticed the aircraft was rolling down the runway approaching take off speed. Luckily there were no aircraft on the runway; crossing or on final. The pilot later apologized for the error because he now knows where he went wrong. At no time did I ever taxi the aircraft onto the runway or clear him to take off in addition; the pilot never gave me any indications that he was confused with my 7110.65 instructions.

It's almost to the point where we are just going to have to tell each aircraft to 'Hold Short' and then get the read back in order to get 100% compliance. The other thing we should consider is let the aircraft call LC directly for the sequence. They established this procedure when APA was working over 440;000 ops per year but we are working less than half of that now. New times require new directions or procedures.
