Is the following scenario familiar? The rate of descent on the glide slope depends on. The 1.5-minute leg comes to play at 15k 10% RULE: 15 = 1.5 minutes, Timing inbound is measured from the point that the aircraft is wings level, inbound to the holding fix, to the time the aircraft crosses the holding fix, Outbound time is adjusted to achieve the correct inbound timing, Outbound leg timing begins over/abeam the fix, whichever occurs later, If the abeam position cannot be determined, start timing when the turn outbound is completed, Abeam is when the needle drops below the 90 benchmark in the HSI, not the TO/FROM flip, The initial outbound leg should be flown for 1 minute or 1 1/2 minutes (appropriate to altitude), Pilots may use any navigational means available; i.e., DME, RNAV, etc., to ensure the appropriate inbound leg times, Timing is generally associated with VOR holding, but some TACAN holds may require timing if no specified DME in the holding clearance, Holding protected airspace is designed based in part on pilot compliance with the three recommended holding pattern entry procedures, Deviations from these recommendations, coupled with excessive airspeed crossing the holding fix, may in some cases result in the aircraft exceeding holding protected airspace, Holding consists of several orbits in an oval-shaped pattern, The entry orbit establishes the aircraft into the holding pattern, When approaching the holding fix from anywhere in sector (c), the direct entry procedure would be to fly directly to the fix and turn to follow the holding pattern [, When approaching the holding fix from anywhere in sector (a), the parallel entry procedure would be to turn to a heading to parallel the holding course outbound on the non-holding side for one minute, turn in the direction of the holding pattern through more than 180 degrees, and return to the holding fix or intercept the holding course inbound [, Right turns: first turn left, then left, and finally right, Left turns: first turn right, then right, and finally left, When approaching the holding fix from anywhere in sector (b), the teardrop entry procedure would be to fly to the fix, turn outbound to a heading for a 30-degree teardrop entry within the pattern (on the holding side) for one minute, then turn in the direction of the holding pattern to intercept the inbound holding course [, Remember Left Add Right Subtract, or LARS for short, While other entry procedures may enable the aircraft to enter the holding pattern and remain within protected airspace, the parallel, teardrop, and direct entries are the procedures for entry and holding recommended by the FAA, derived as part of the development of the size and shape of the obstacle protection areas for holding, The no wind orbit begins the second time the aircraft crosses the station or fix, allowing the pilot to determine the initial corrections required for existing winds, As the name suggests, this orbit is flown as if there were no-wind for which to compensate, If this were true, you would (1) roll out of your inbound turn on the holding course and (2) inbound timing to the holding fix, if required, would equal the amount of time outbound, Pilots must execute the no-wind orbit as precisely as possible to identify initial corrections, The third and subsequent orbits in holding are called correction orbits, Correction orbits apply the correction factors determined on the previous orbit to the outbound leg of the holding pattern, Adjust the heading by the correction factor determined on the no-wind orbit, Confirm EFC 5 minutes before it is reached, Compensate for wind effect primarily by drift correction on the inbound and outbound legs, 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, Apply full correction outbound (if off 10, apply 10), Use full correction into the wind on the outbound leg, Use half correction into the wind on the inbound leg, DME of longest leg X degrees off = correction factor you will use, Air Traffic Control clearances will come with a clearance limit, be in the airport (no delay expected), or a NAVAID (delay expected), When no delay is expected, the controller should. Now that you know the types of hold entries, how do you determine which one to fly in the air? Using the top of your thumb, draw a line across the HSI. Fly a direct entry after crossing REVME. You arrive at the 15 DME fix on a heading of 350. The meaning of HOLDING PATTERN is the usually oval course flown (as over an airport) by aircraft awaiting clearance especially to land. Dictionary Entries Near holding pattern. The end of the outbound leg of the holding pattern is reached when the ATD reads the specified distance [, Substitution of RNAV computed distance to or from a NAVAID in place of DME distance is permitted when holding.
