Over fly the airport at 500-1,000' above traffic pattern altitude to observe traffic, wind direction indications, etc. In lieu of a tetrahedron and where a wind sock or wind cone is collocated with a wind tee, the wind tee may be manually aligned with the runway in use to indicate landing direction. How do you safely position yourself to make that 45-degree entry to the downwind leg at a nontowered airport, take the wind and terrain (airport advisories are not always available and you can only discern so much from a sectional) into account, and get a good look at an unfamiliar airport? Always check the A/FD and don’t always go by what Foreflight says. Didn't find something you're looking for? Remember, everything is reversed, so turn left (into the wind) when making your course reversal. to determine a runway to use At least 2 NM from the runway, enter the traffic pattern at traffic pattern altitude on a 45° entry to the downwind, maintaining a none-half mile distance from the runway on the downwind leg The A/FD is always right and usually has a little more detail to help set you straight. Is 1300 MSL a safer pattern altitude in this example? So, legally, you could fly at 699 AGL (which at CVB would be 1,472 MSL) while in the pattern and be legal. ///////////////////////////////// Copyright © On the Airports page with KAQO pulled up, tap the A/FD tab, second to last on the left. Pilots are cautioned against using a tetrahedron for any purpose other than as an indicator of landing direction. On the second line of the A/FD entry, it says TPA-See Remarks. Let’s go back to KSGR and put a 1,000 AGL overcast ceiling there. Well, that is 527 AGL, so probably not, since towers tend to stick up that high sometimes. Maybe, but probably not if you are skimming the base of the clouds. From what we just learned, 1,902′ MSL is not 1,000 AGL, so is 1,902′ MSL otherwise established? This is the best and safest entry, because it enables you to see other pilots in the pattern and enables those in the pattern to see you. The self-announce procedure should also be used if a pilot is unable to communicate with the FSS on the designated CTAF. Availability of the automated UNICOM will be published in the Chart Supplement U.S. and approach charts, There are three advisory type services provided at selected airports, Local Airport Advisory (LAA) is available only in Alaska and provided at airports that have a FSS physically located on the airport, which does not have a control tower or where the tower is operated on a - basis. It takes a few minutes of thought (preferably on the ground), but it will save you time (and money) each time you enter a traffic pattern. Since most traffic patterns are between 800 and 1,000 feet above ground level (agl) &mdash don't forget that faster, heavier, or turbine aircraft typically fly the traffic pattern at 1,500 agl &mdash this should put you around 2,000 feet agl or above. A CTAF is a frequency designated for the purpose of carrying out airport advisory practices while operating to or from an airport without an operating control tower. RP* indicates special conditions exist and refers pilots to the Chart Supplement U.S. If ceilings are less than 500 feet above the pattern altitude, you'll need to fly outside the pattern perimeter to enter it. An airport may have a full or part-time tower or FSS located on the airport, a full or part-time UNICOM station or no aeronautical station at all. Get the latest news on coronavirus impacts on general aviation, including what AOPA is doing to protect GA, event cancellations, advice for pilots to protect themselves, and more. Foreflight states the elevation as 82′ MSL and the Pattern Altitude as 1,000′ MSL. What’s the lesson here? The facilities may be indistinguishable to pilots since they are all referred to as tower and no publication lists the degree of radar use, Therefore, when in communication with a tower controller who may have radar available, do not assume that constant radar monitoring and complete ATC radar services are being provided. Figuring out the pattern altitude at an airport should be pretty simple, right? Remember, you should be flying with your head up and swiveling, looking for traffic. Both the AIM and the Pilot’s Handbook of Aeronautical Knowledge, when talking about pattern altitude, state, “When operating at an airport, traffic pattern altitudes should be maintained unless otherwise required by the applicable distance from cloud criteria in…section 91.155.” 91.155 defines basic VFR weather minimums. In order to stay 500 feet below the clouds, you would be flying a 582 MSL pattern. Just use your heading indicator (HI), which some pilots call the directional gyro (DG), and think in three dimensions. There are three ways for pilots to communicate their intention and obtain airport/traffic information when operating at an airport that does not have an operating tower: Many airports are now providing completely automated weather, radio check capability and airport advisory information on an automated UNICOM system. Level off at pattern altitude. Probably not, though it is legal. Likewise, pilots operating in the traffic pattern should be alert at all times for aircraft executing straight-in approaches, *RP indicates special conditions exist and refers pilots to the Chart Supplement U.S, Right traffic patterns are not shown at airports with full-time control towers, A flight path parallel to the landing runway in the landing direction, This leg is the ground path flown immediately after takeoff, A flight path at right angles to the landing runway off its takeoff end, The direction of the crosswind leg (left or right turn) is dictated by the airport publications or tower, A flight path parallel to the landing runway in the opposite direction of landing, While it is the longest leg, it requires the most vigilance for traffic entering and departing, A flight path at right angles to the landing runway off its approach end and extending from the downwind leg to the intersection of the extended runway centerline, A flight path in the direction of landing along the extended runway centerline from the base leg to the runway, Before touching down, check for waive-off lights if present, or light signals from tower, The flight path which begins after takeoff and continues straight ahead along the extended runway centerline, The departure climb continues until reaching a point at least 1/2 mile beyond the departure end of the runway and within 300 feet of the traffic pattern altitude, May exit 45° off in the direction of the pattern turns as well, Traffic pattern altitudes (discussed below) should be maintained unless another traffic pattern altitude is published in the Chart Supplement U.S. or unless otherwise required, Propeller-driven aircraft enter the traffic pattern at 1,000 feet above ground level (AGL), Large and turbine-powered aircraft enter the traffic pattern at an altitude of not less than 1,500 feet AGL or 500 feet above the established pattern altitude, Helicopters operating in the traffic pattern may fly a pattern similar to the fixed-wing aircraft pattern, but at a lower altitude (500 AGL) and closer to the runway. Better yet, you should have stayed home or done some hangar flying that day. Look up KAQO, the Llano Airport on Foreflight. Some airport managers have specified that under certain wind or other conditions designated runways be used. It is essential that pilots be alert and look for other traffic and exchange traffic information when approaching or departing an airport without an operating control tower. This will fly you over to the right-hand pattern, where the entry is flown the same way. Similar treatment of the indicator at the departure end of the runway will clearly indicate the direction of turn after takeoff, When two or more aircraft are approaching an airport for the purpose of landing, the pilot of the aircraft at the lower altitude has the right-of-way over the pilot of the aircraft at the higher altitude. Maintain your heading away from the airport until you have descended 500 feet (1 minute). Airport traffic patterns are developed to ensure that air traffic is flown into and out of an airport safely. What altitude can you do pattern work at to stay legal? At the top of the page, the airport elevation is stated as 1,101′ MSL and the pattern altitude is stated as 1,902′ MSL. A departing aircraft should initiate contact before taxiing, reporting aircraft identification and type, VFR or IFR, location on the airport, intentions, direction of take-off, possession of the automated weather, and request airport advisory or information service. Pattern altitude there is 1,602 feet, which is 829 AGL. Please login below for an enhanced experience. As you pass over the airport, look at your heading indicator. However, the pilot operating at the lower altitude should not take advantage of another aircraft, which is on final approach to land, by cutting in front of, or overtaking that aircraft, There have been several incidents in the vicinity of controlled airports that were caused primarily by aircraft executing unexpected maneuvers, Controllers establish the sequence of arriving and departing aircraft by requiring them to adjust flight as necessary to achieve proper spacing, These adjustments can only be based on observed traffic, accurate pilot reports, and anticipated aircraft maneuvers, Pilots are expected to cooperate so as to preclude disrupting traffic flows or creating conflicting patterns, The pilot-in-command of an aircraft is directly responsible for and is the final authority as to the operation of the aircraft, On occasion it may be necessary for pilots to maneuver their aircraft to maintain spacing with the traffic they have been sequenced to follow, The controller can anticipate minor maneuvering such as shallow "S" turns, The controller cannot, however, anticipate a major maneuver such as a 360° turn, If a pilot makes a 360° turn after obtaining a landing sequence, the result is usually a gap in the landing interval and, more importantly, it causes a chain reaction which may result in a conflict with following traffic and an interruption of the sequence established by the tower or approach controller, Should a pilot decide to make maneuvering turns to maintain spacing behind a preceding aircraft, the pilot should always advise the controller if at all possible, Remember that it is not required to have a radio (and therefore make radio calls) prior to takeoff or landing at an uncontrolled airfield, Instances where an aircraft fails to (or even attempts) to takeoff and land on the wrong runway or taxiway generates a "wrong surface event" reporting, Additional resources are available through tools such as the FAA's.
