Hi,
when approaching the OSN VOR with HDG 109 (also IAF for EDDG RNP25) for a parallel entry into the holding: The magenta line is steering me to the holding fix (OSN) and AFTER passing the fix a turn anticipation occurs to intercept the outbound leg for the parallel entry, thus as the fix is handled as a must fly waypoint, what is not true. This behavior shoots me complete into the non-holding side which is NOT safe in my opinion. Further when exiting the holding the unit puts my to first overfly the fix BEFORE intercepting thereafter the outbound leg for the approach. This results in overshooting the outbound leg. I have added screenshots:
What is correct?
Any comments on that? |

My answer is C BTW – standard parallel hold entries are described in the
AIM to be flown outbound on the nonholding side: (a) Parallel Procedure. When
approaching Either GPS method appears to keep the aircraft within the protected
holding airspace as long as the entry is performed at or below the applicable max
holding airspeed. |

Think this way, turn in the shortest direction to parallel the "outbound course" outbound. Yes, that may put you on the "non" holding side for that first turn... Here is an easy way to think about holding.. If you are within 70 degrees of the holding course at the holding fix, turn in the direction of "holding", if not, turn the shortest direction to parallel the out bound course outbound... 51-37? |

I agree, C is the right answer.
Nevertheless Garmin makes it much more elegant and smoother especially when flying with GPSS and autopilot. Thank you
