Narrative: Please consider changing/eliminating the Deer Valley One procedure!The Deer Valley One obstacle departure is improbable if not impossible in a high-performance airplane.1. Chart does not tell you how close the turn is.2. Turn needs to be completed by 1.6 nm from end of runway! This alone should never never be permitted.3. Turn radius at 200 kts. is likely about 1.3 nm.4. 400 ft. V2 +10 flaps up igniters off Venr takes about 2nm min. And way longer in this scenario.5. And wait until you add what happened to me; a traffic call for departing traffic on parallel runway in the direction of my needed turn.6. That took time to find and alter course to avoid the traffic that was about 500 ft. away at the same altitude!6b. That traffic prohibited a turn to [Heading] 336 as required to occur at about 100 ft. if I was to make the turn in time.7. Then the TCAS resolution screen took time to resolve that first conflict.8. Then the instant that screen was resolved; a second additional 'traffic traffic' call occurred for another item of traffic that I could never visually acquire. Box said above and slightly ahead as I recall. Right near my course; so it was a serious safety concern.9. Then the second TCAS screen took time to resolve that second traffic call.10. Now it's finally time for 400 ft. V2 + 10; flaps up igniters off; recall Venr.11. By this time I'm coming upon 5;000 ft. considering engaging the autopilot; but the Flight Director is not aligned because so close and capturing.12. Stuff it down to capture; but overshot 5;000 ft. slightly.13. And now it's finally time to do the turn; but ATC asked what's up.Well ...How can you design a turn that needs to be completed in 1.6nm which would mean it must be started at about 100 ft. AGL = unsafe & no jet should turn before 400 ft. as trained.And look at the chart; no indication how close that is.And compounding my situation is that the PXR VOR was out of service.I submit it's impossible in a high performance airplane. Do it in the sim without telling the pilot in advance and with and without being a regular at the field; and I estimate you'll get max 10% compliance. Who would design for a 90% potential of non-compliance?Please have them redesign/eliminate this departure!




Synopsis: Pilot in a high performance small transport aircraft reported the Deer Valley One Deparure out of DVT needs to be redesigned due to safety concerns.
