How do you fly into and out of KDEN on VATSIM?

What is VATSIM, and can you fly KDEN without owning a plane?

VATSIM is a free online air-traffic-control network for flight simulators. You fly a simulated aircraft into or out of KDEN, so you do not need to own a real plane. You need a VATSIM account, a compatible simulator and pilot client, plus an aircraft suitable for the route and procedure.

Simulator: General. This guidance applies to compatible desktop installations of Microsoft Flight Simulator, X-Plane, Prepar3D and FSX. The normal VATSIM workflow depends on a separate pilot client and voice connection, so owning a console edition alone does not guarantee network compatibility.

The procedures below assume an IFR flight, as used for most airline operations. An airliner is not compulsory, but the simulated aircraft must be able to fly the navigation, altitude and performance requirements you accept. VFR pilots must still comply with online ATC instructions and obtain an explicit Class B clearance when required.

How do I find KDEN route details before filing?

Build the route from a planning source using effective navigation data, then verify every KDEN procedure, transition and runway against current charts and the AIRAC cycle installed in the aircraft.

VATSIM operational information and real-world FAA chart data serve different purposes. Use the network controller list and ATIS for staffing and online instructions; use current official or approved charts for the procedures themselves. A real-world ATIS should not be treated as the VATSIM runway assignment.

1. Start with a suitable route source. Select the correct aircraft capability, KDEN departure or arrival, destination, cruise level and effective navigation cycle. Avoid copying an old saved route without checking that its airways and fixes still exist.
2. Open the relevant charts. Our KDEN airport diagram and procedure chart set provides the diagram, SIDs, STARs, approaches, runway information and frequencies. Check each chart's effective date or revision.
3. Connect the procedures to the en-route section. A departure must reach an appropriate route entry point; an arrival must begin at a transition available from the direction of flight. Confirm the runway transition rather than loading only the SID or STAR name.
4. Compare the chart with the avionics. Verify the procedure name, transition, first fixes, altitude constraints and runway. FAA chart revisions and the aircraft's AIRAC cycle are separate checks: a new chart can expose a stale navigation database.
5. Validate the cruising altitude. It must suit the direction, airspace, aircraft performance and applicable flight-level rules. The filed altitude is a request, not authority to climb or descend.
6. Review network information before connecting. Check the controller list, ATIS and any controller information for runway use, preferred routing or amendments. ATC may still issue a different route after contact, and that clearance supersedes what was filed.

KDEN VATSIM pre-flight checklist

Complete this checklist before connecting at a gate so that route or radio problems do not have to be solved while blocking a taxiway.

• VATSIM account and pilot client: Confirm that the account works, the correct simulator is selected, voice is configured and model matching will not produce errors. FSX pilots can follow our FSX-to-VATSIM client and connection walkthrough.
• Microphone and radios: Select the intended input and output devices, test push-to-talk, prevent an open microphone and confirm that COM transmit and receive selections work. Request a short radio check only if the client's own audio test leaves doubt.
• Aircraft position: Spawn cold or parked at an unoccupied gate or stand. Never connect on a runway, taxiway or another aircraft.
• Callsign: Use exactly the same callsign in the pilot client, flight plan and radio calls. A one-character mismatch makes identification difficult.
• Flight-plan fields: Check flight rules, aircraft type and equipment, departure, destination, alternate where applicable, route, cruise speed and level, times and remarks. Our VATSIM flight-plan filing guide explains the required entries.
• Route details: Verify the SID or STAR transition, en-route joins, cruise altitude and AIRAC compatibility. Keep the filed route available even after programming it.
• ATIS: Record the VATSIM ATIS identifier, altimeter setting, advertised runways and any network-specific instruction. The runway remains planning information until assigned or selected under unstaffed-airport guidance.
• Charts: Have the airport diagram, assigned or likely departure, arrival and approach open before moving.
• Performance: Calculate take-off or landing data using the aircraft's proper method, including runway, wind, temperature, pressure, weight and KDEN elevation.

How do you depart KDEN on VATSIM?

A safe KDEN departure follows the clearance actually issued by ATC, not the route, runway or SID that happened to be filed.

1. Identify the controller providing service. Use the VATSIM controller list and ATIS. Denver Approach or Denver Center may cover KDEN from the top down when a local position is offline; do not call an unstaffed chart frequency simply because it is printed on the airport diagram.
2. Request and copy the IFR clearance. Give the callsign, parking area, destination and ATIS code. A suitable opening is Denver Clearance, [callsign], at [stand], IFR to [destination], information Alpha, ready to copy. Record the clearance limit, route or SID, altitude, departure frequency and transponder code. Required readback: read back those clearance elements and every amendment; an altitude preceded by expect is not an authorised altitude.
3. Programme and verify the departure. Enter the assigned runway, SID, runway transition, en-route transition and initial altitude. Compare the first fixes, headings, speed restrictions and altitude constraints with the chart. If a procedure is missing, say Denver Clearance, [callsign], unable assigned SID; it is not in our navigation database. Request an amended departure or vectors.
4. Obtain pushback and taxi instructions. Follow the ATIS and controller information for ramp operations; these can differ by staffing configuration. Write down the taxi route and trace it on the diagram before moving. Required readback: include the runway assignment and every hold-short instruction with the complete runway designator.
5. Stop at each runway hold line. A taxi clearance never provides an implied runway crossing. Cross or enter a runway only when an online controller explicitly names that runway in a clearance addressed to the aircraft. Required readback: repeat every hold-short or runway-crossing instruction, including Left, Centre or Right.
6. Verify the departure runway. Compare the sign, runway number, aircraft heading, departure course, first fix and cleared altitude. Line up and wait permits runway entry but not take-off. Required readback: acknowledge the line-up or take-off clearance with the full runway designator and callsign.
7. Fly only the authorised climb. Follow the SID, runway heading or radar vector exactly as cleared. Climb via SID authorises the published lateral path and applicable altitude and speed constraints up to the cleared altitude; an FMC profile alone is not clearance to climb.

How do you fly an arrival into KDEN?

Brief the arrival and approach before descent because a KDEN runway change can alter the transition, navigation setup, restrictions, minima and taxi plan.

1. Review the STAR and ATIS early. Compare the expected arrival with the filed route and aircraft database. Note the advertised landing runway, but do not assume it is assigned until instructed by ATC or selected under the applicable unstaffed-airport procedure.
2. Check in with the correct information. Report the callsign, present altitude, assigned altitude or STAR and ATIS identifier. Required readback: repeat assigned headings, altitudes, speeds, direct-to clearances and runway assignments; include any restriction such as at or above or until established.
3. Descend only when authorised. Top of descent and VNAV do not provide clearance. Maintain the last assigned altitude until ATC issues a lower altitude, a descend via clearance or an approach clearance that permits published descent. A descend via clearance requires compliance with the applicable published altitude and speed restrictions unless amended.
4. Handle runway changes before going heads-down. Read back the new runway and assess track miles, fuel, aircraft configuration, navigation setup and workload. For an unsafe late change, say Denver Approach, [callsign], unable the runway change at this point; request vectors and additional time to reconfigure. ATC would rather amend the sequence than have the aircraft fly the wrong approach.
5. Brief the exact approach. Confirm the runway suffix, transition, navigation source, final course, altitude constraints, minima and missed approach. Our approach-chart briefing guide explains how to identify these items. When vectored to final, maintain the assigned altitude until established and authorised to descend.
6. Accept a visual approach only when ready. Have the airport or relevant traffic in sight and be able to continue safely. If not, report unable visual and request an instrument approach. Required readback: acknowledge the approach and landing clearances with the exact runway designator and callsign.
7. Vacate completely and request taxi. Cross the runway-side hold marking before stopping, remain on the assigned frequency until handed off and tell ground which concourse, ramp or parking area is required. Crossing another runway still requires an explicit crossing clearance and readback.

If a go-around is necessary, establish the climb, announce it promptly and follow ATC instructions. If no instruction is available, fly the charted missed approach rather than improvising a turn towards the downwind.

Why does KDEN require extra performance planning?

KDEN sits about 5,434 feet above mean sea level, so high temperature can produce substantial density altitude and weaker acceleration, climb and piston-engine power. Charted altitudes are MSL: an indicated 8,000 feet is only about 2,600 feet above the airport.

Use the aircraft's approved performance method rather than sea-level assumptions. Check take-off distance, climb limits, landing distance, thrust or power settings and mixture where applicable. A long KDEN runway does not remove the need to verify that the selected runway, weight and weather produce acceptable margins.

What KDEN mistakes cause the most trouble on VATSIM?

What should you do when KDEN has no online ATC?

An offline Denver Tower does not automatically make KDEN unstaffed. Check the VATSIM controller list because Denver Approach or Denver Center may provide top-down service. Their network frequency and instructions take precedence over assumptions based on real-world chart frequencies.

If no controller covers the airport, follow the current VATSIM Code of Conduct and the applicable regional guidance for advisory operations. Use the designated advisory or CTAF frequency specified by that guidance; do not hard-code a universal frequency from an old tutorial.

Make concise position and intention calls before taxiing, entering or crossing a runway, departing, joining the approach and after vacating. These are advisory calls, not clearances, and they do not transfer separation responsibility to another pilot. Continue using published procedures, monitor nearby network traffic and never announce that a runway is clear without checking it visually and through the simulator's traffic display.
