One is by flying directly to the fix and the other is by intercepting the inbound leg at an angle of 45 degrees and proceeding to the fix thereafter. After passing the holding fix the airplane is turned to the outbound leg. In a tear-drop entry, the airplane is turned towards the holding side in an angle of 30 degrees from the inbound leg. After one minute it is turned towards the non holding side until the inbound leg is intercepted. When approaching the holding fix exactly on the holding course from the opposite side of the inbound leg, either a parallel or a tear-drop entry can be used.
Reality is that the recommended entry is also the easiest to execute.
The problem is how to make a quick determination of the recommended entry without being distracted by it from performing other tasks. The quickest and most efficient way to make this determination is by super-imposing the hold onto the heading indicator. This results in visualization of the position in which the airplane approaches the holding fix and of the holding pattern itself. This is accomplished by dividing the directional gyro card into three sectors. For a standard holding pattern one sector is between the heading of the airplane and 70 degrees to the right of it.
