Pilots can request ATC to allow them to join the hold. Amazon.com: ASA Holding Pattern Computer : Electronics If youre on hold for a long time, youll burn off enough fuel to significantly change the aircrafts weight and the position of the Center of Gravity. The holding pattern would only be a segment of the IAP if it is published on the instrument procedure chart and is used in lieu of a procedure turn, DME/GPS holding is subject to the same entry and holding procedures except that distances (nautical miles) are used in lieu of time values, The outbound course of the DME/GPS holding pattern is called the outbound leg of the pattern, The controller or the instrument approach procedure chart will specify the length of the outbound leg, The end of the outbound leg is determined by the DME or ATD readout, The holding fix on conventional procedures, or controller defined holding based on a conventional navigation aid with DME, is a specified course or radial and distances are from the DME station for both the inbound and outbound ends of the holding pattern, When flying published GPS overlay or stand alone procedures with distance specified, the holding fix will be a waypoint in the database and the end of the outbound leg will be determined by the ATD, Some GPS overlay and early stand alone procedures may have timing specified, When the inbound course is toward the NAVAID, the fix distance is 10 NM, and the leg length is 5 NM, then the end of the outbound leg will be reached when the DME/ATD reads 15 NM [, When the inbound course is away from the NAVAID and the fix distance is 28 NM, and the leg length is 8 NM, then the end of the outbound leg will be reached when the DME/ATD reads 20 NM [, The inbound course is always toward the waypoint and the ATD is zero at the waypoint. Holding instructions are lengthy and complicated so its good practice to keep a pencil handy when youre ready to copy holding clearance.

Cross the holding fix, initially, at or below the maximum holding airspeed. If you are learning holding patterns and hold entries, this videowill help practice figuring hold entry method based on the locationthe aircraft is coming from. Conversely, tailwinds can shorten the inbound leg time. If you look at the back of your hand, the angle between the thumb and the index finger is similar to the 70-degree angle that the sector dividing line uses.

A "fly-by" turn during a direct entry from the holding pattern side of holding course may result in excursions beyond protected airspace, especially as the intercept angle and ground speed increase, During holding, RNAV systems furnish lateral steering guidance using either a constant bank or constant radius to achieve the desired inbound and outbound turns. Continue on the inbound course to intercept the fix again, and then turn right to join the outbound as usual. If you are entering the hold from the thin side, chop the holding pattern between the protected side and the non-protected side (see the blue line).
