Practice holding pattern entries on your own time and convenience, so that choosing the proper one in the air becomes a breeze. A holding pattern is a method of delaying an aircraft already in flight, by having it fly a racetrack pattern within a specified airspace. When Should You Initiate A 'Pilot's-Discretion' Descent? Now that you've split up the HSI, find what section of the HSI your outbound course lies on, and plan to fly that entry. Place your thumb on the 3 o'clock (right turns, right thumb) or 9 o'clock (left turns, left thumb) position on the HSI. With a strong headwind against the outbound leg, RNAV systems may fly up to and possibly beyond the limits of protected airspace before turning inbound. To determine the type of entry, pilots can utilize many different methods: Raise the left side of the pencil 20 and see where the reciprocal course lies, Raise the right side of the pencil 20 and see where the reciprocal course lies, There will be cases in which the reciprocal will fall on, or very close to (5) a sector boundary in which case the entry procedures for either section are acceptable, When an aircraft is 3 minutes or less from a clearance limit and a clearance beyond the fix has not been received, the pilot is expected to start a speed reduction so that the aircraft will cross the fix, initially, at or below the maximum holding airspeed, Crossing the holding fix, perform the "5 Ts", Perform all turns at 3 per second; or 30 angle of bank; or 25 angle of bank if using a flight director system, whichever requires the least bank angle, After completion of outbound timing (according to altitude) or at the specified DME, turn (standard rate) to intercept the holding course inbound, During the last half of the turn, check the position of the head of the needle relative to the holding course, The head of the needle should always be in a place to fall onto the course when you're checking your turn inbound, If not on course, stop the turn with a double the angle intercept for VOR holding, When turning to intercept the inbound course in TACAN holding, an intercept greater than double the angle will be required, Begin timing once wings level inbound to the fix or station, This is to compensate for greater spacing between radials when holding away from the station, In TACAN holding, a 30 to 45 angle of intercept will establish the aircraft on the inbound course, Once established on course, commence tracking inbound to the holding fix, It is critical to establish the aircraft on course before crossing the holding fix, Continue to the station and initiate your turn in the direction of holding to begin the no wind orbit, Roll out of the turn on the outbound heading parallel to the holding course, Start the outbound leg timing, if required, when wings are level or abeam the station, whichever occurs later, If the abeam position cannot be determined, start timing when the turn to the outbound leg has been completed, When holding at a VOR station, pilots should begin the turn to the outbound leg at the time of the first complete reversal of the to/from indicator, At the completion of the outbound leg timing or at the specified DME, turn toward the holding radial to intercept the holding course, As you roll wings level, check the position of the head of the needle to the holding course, If they differ, note the number of degrees difference, This will determine the amount of heading correction to use on the outbound leg of your correction orbit, If you had to set an intercept when you turned inbound, there are winds to correct for, When checking the wind, resist the temptation to check wind from the head of the needle because it will be on the top of the RMI where you are looking; this will give you opposite winds causing an error, Establish the aircraft on the holding course and track inbound to the holding fix, Start inbound time at wings-level on the inbound course or on a heading to intercept the inbound course, whichever occurs first. | Privacy Policy | Terms of Service | Sitemap | Patreon | Contact, Hold east of the Ormond VORTAC on the 090 radial, left turns, maintain 5,000,' expect further clearance 0+50, specified airspace that is reasonably protected, federal aviation regulation 91.159 (VFR cruising altitude), http://www.lunabase.org/~faber/Vault/software/hold_quiz/, Aeronautical Information Manual (4-4-3) Clearance Items, Aeronautical Information Manual (5-3-7) Minimum Turning Altitude (MTA), Aeronautical Information Manual (5-3-8) Holding, Aeronautical Information Manual (5-4-9) Procedure Turn and Hold-in-lieu of Procedure Turn, Federal Aviation Administration - Airman Certification Standards, Federal Aviation Administration - Pilot/Controller Glossary, As the name suggests, holding is the act of delaying an aircraft from proceeding on course, Holding can be accomplished at a Navigational Aid (NAVAID), a fix, or an intersection, dictating how pilots execute their, Practice holding procedures is critical as this can be a perishable skill. Quiz: These 6 Aerodynamic Designs Are For Quiz: Do You Know These 5 IFR Aircraft Requirements? What is the significance of an ATC clearance which reads "CRUISE SIX THOUSAND"? Fullscreen Practice choosing the right holding pattern entry, that is, direct, teardrop, or parallel. https://dylanrush.s3. 3) ATC clears: "Saratoga Two Three Eight, hold Southwest of the Goodland VORTAC on the 230 radial, expect further clearance at 1515 zulu." Practice choosing the right holding pattern entry, that is, direct, teardrop, or parallel. When should you start your speed reduction? Make all turns during entry and while holding at: 25 degree bank provided a flight director system is used, NOTE-Use whichever requires the least bank angle, Compensate for wind effect primarily by drift correction on the inbound and outbound legs. You receive this ATC clearance: He graduated as an aviation major from the University of North Dakota, and he's been flying since he was 16. If you understand the basics and draw it, the AIM preferred entry (which is what is being tested on the knowledge test) becomes obvious more than 90% of the time. Which holding pattern correctly complies with the ATC clearance below, and what is the recommended entry procedure? Which of the following would be an operational consideration? simultaneously monitoring two frequencies. Here are 4 great rules-of-thumb to use on the hot days ahead of you. But first, let's review the three types of hold entries to set you up for the perfect holding pattern. If you are flying a holding pattern with right-hand turns (a standard pattern) use your right thumb. What characteristics should be observed when a headwind shears to be a constant tailwind? During a precision radar or ILS approach, the rate of descent required to remain on the glide slope will. If unable to issue a clearance to the destination, an ATC clearance requiring an aircraft to hold at a fix where the no pattern is charted will include the following information: The direction of holding from the fix in terms of the eight cardinal compass points (i.e., N, NE, E, SE, etc. The middle and far bars of a 3-bar VASI will, constitute a 2-bar VASI for using the upper glidepath. 4) Mentally draw out the entry zones. The pilot must request the approach, have at least 1 mile visibility, and be reasonably sure of remaining clear of clouds. Some systems do not store all holding patterns, and may only store patterns associated with missed approaches and hold-in-lieu of procedure turn (HILPT). By the time you've figured out what's going on, you've already passed the holding fix and don't know what to do next.

To ensure proper airspace protection while holding at 5,000 feet in a civil aircraft, what is the maximum indicated airspeed a pilot should use? The standard altitude blocks that we are concerned with are: These altitude blocks correspond to maximum airspeeds, Holding patterns may be restricted to a maximum speed, Holding speeds are based on an expected turn radius to keep pilots clear of obstacles, Charts depict speed restriction in parenthesis inside the holding pattern on the chart: e.g., (175), Pilots unable to comply with the maximum airspeed restriction should notify ATC, The aircraft should be at or below the maximum speed before initially crossing the holding fix to avoid exiting the protected airspace, Holding patterns from 6,001' to 14,000' may be further restricted to 210 KIAS, Note that holding speeds change at 14,001 (as does the holding time (1.0 to 1.5 minutes)), All helicopter/power lift aircraft holding on a "COPTER" instrument procedure is predicated on a minimum airspeed of 90 KIAS unless charted otherwise, When a published procedure directs a climb-in hold (i.e., "Climb-in holding pattern to depart XYZ VORTAC at or above 10,000" or "All aircraft climb-in TRUCK holding pattern to cross TRUCK Int at or above 11,500 before proceeding on course"), an additional obstacle protection area allows for greater airspeeds in the climb for those aircraft requiring them, Climb-in-holding permits a maximum airspeed of 310 KIAS unless a maximum holding airspeed is published, in which case that maximum airspeed is applicable, Where the holding pattern is restricted to a maximum airspeed of 175 KIAS, the 200 KIAS holding pattern template has been applied for published climb-in hold procedures for altitudes 6,000 feet and below and the 230 KIAS holding pattern template has been applied for altitudes above 6,000 feet, The airspeed limitations in 14 CFR Section 91.117, Aircraft Speed, still apply. Preventive Maintenance: Here's What You Can Fix On Your Plane, Why You Shouldn't Fly With A Dirty Windshield. 2) Outbound course is 284 degrees. Determine the outbound course for the hold. Fortunately, there are a few techniques to help reduce your workload. Pilots extracting the holding pattern from the navigation database are responsible for confirming that the holding pattern conforms to the assigned charted holding pattern in terms of turn direction, speed limit, timing, and distance, If ATC assigns holding that is not charted, then the pilot is responsible for programming the RNAV system with the assigned holding course, turn direction, speed limit, leg length, or leg time, Changes made after the initial execution may not apply until the next circuit of the holding pattern if the aircraft is in close proximity to the holding fix, Treat intersection holding as if it were a VOR, The NAVAID and radial from that NAVAID upon which the holding pattern is oriented, The NAVAID and radial from that NAVAID which defines the holding fix (intersection) on the primary radial, When flying a point-to-point to an intersection you will likely hit one radial before the other; just keep the same holding entry procedures in mind and apply them here, When holding at a VOR station, the reciprocal of the holding course is ALWAYS the same as the radial, At an intersection, however, this will only be true when the holding pattern is oriented so that the inbound leg is toward the station, When that fix is an intersection, the inbound holding course could possibly be away from the station, Request a few turns in holding when you want practice, If you request 1 turn in holding, your entry doesn't count, In other words when you enter holding at first and initially pass the fix (even if a direct entry), then that orbit doesn't count, 1 full round in the pattern is the 1 you requested, Reverse sensing is a conditions where the navigation instrument indicates the inverse of what it should, Usually it is just an ATC instruction to remain clear of a particular area or airspace, or to circle a known point, Sometimes it is a little more in-depth and part of local traffic flow such as for an event; for example, Oshkosh, Whenever an aircraft is cleared to a fix other than the destination airport and delay is expected, it is the responsibility of ATC to issue complete holding instructions (unless the pattern is charted), an EFC time and best estimate of any additional en route/terminal delay, Only those holding patterns depicted on U.S. government or commercially produced (meeting FAA requirements) low/high altitude en route, and area or STAR charts should be used, If the holding pattern is charted and the controller doesn't issue complete holding instructions, the pilot is expected to hold as depicted on the appropriate chart, When the pattern is charted on the assigned procedure or route being flown, ATC may omit all holding instructions except the charted holding direction and the statement AS PUBLISHED; for example, HOLD EAST AS PUBLISHED, ATC must always issue complete holding instructions when pilots request them, If no holding pattern is charted and holding instructions have not been issued, the pilot should ask ATC for holding instructions prior to reaching the fix, This procedure will eliminate the possibility of an aircraft entering a holding pattern other than that desired by ATC, If unable to obtain holding instructions prior to reaching the fix (due to frequency congestion, stuck microphone, etc. The horizontal distance a pilot should see when looking down the runway from a moving aircraft. Fortunately, we have two tips you can use to make it easier. 2) fly this heading for about one minute and turn in the direction of the hold to intercept the holding course to the fix. You receive a holding clearance from ATC, and only have a couple of minutes, sometimes only a few seconds, to choose the correct entry. Check out the example parallel entry drawn out on ForeFlight below: Want a deep dive on holding entries? Parts Of A Holding Pattern If more than one cruising altitude is intended, what information should be entered in item 15, "Level," of the flight plan? Merriam Webster.

Which illustration would a pilot observe if the aircraft is far below the glidepath? The total amount of usable fuel onboard expressed in hours and minutes. Why Add Half The Gust Factor On Windy Day Landings? If an approach is being made to a runway that has an operating 3-bar VASI and all the VASI lights appear red as the airplane reaches the MDA, the pilot should. When outbound, triple the inbound drift correction to avoid major turning adjustments; e.g., if correcting left by 8 degrees when inbound, correct right by 24 degrees when outbound, Determine entry turn from aircraft heading upon arrival at the holding fix; +/-5 degrees in heading is considered to be within allowable good operating limits for determining entry, Holding is a solution to a temporary problem. If you do not display the graphic, you get five points for a correct answer and one penalty point for a wrong answer. To advise of changes in flight data which affect instrument approach procedures (IAP), aeronautical charts, and flight restrictions prior to normal publication. Which of the following would apply? From what source can you obtain the latest FDC NOTAMs? Holding pattern data may be extracted from the RNAV database for published holds or may be manually entered for ad-hoc ATC-assigned holds.
