Tips and tricks for sector entry, holding patterns etc ...
G'day All,
I was wondering if anyone would like to share their favourite tips and tricks to successful sector entry, holding pattern and instrument approaches. For example, I have been told to delay the outbound turn for ten to fifteen seconds after station passage on a sector three entry. This is meant to allow a correct abeam spacing on the outbound leg. Of course, this will only be necessary in some cases depending on the track in. In addition, what is the best way to intercept the correct track to the aid on a sector one or two entry? Is it a good idea to use a 30 degree intercept to the correct track inbound?
In anticipation,
Two Dogs

Press HOLD/Next HOLD - check inbound track and turn direction is correct (eg 272/L) - engage L NAV - sip coffee - watch in wonder - try to remember when you could track NDBs and do NDB holding patterns on a DG and fixed card ADF - shudder - sip coffee 
You will find that given the choice between a sector two and a sector three entry, ie. within 5 degrees zone of flex based on heading (and remember no zone of flex for intersection based holding patterns), you will find a sector two entry will be preferable. Using a sector three entry (because you are already halfway through the outbound turn) will keep you too close to the inbound leg, ie you will most likely find yourself overshooting the inbound turn.
As for intercepting the inbound track, it depends on how far the wind is pushing you and how far from the navaid you are. A 45 degree intercept may be required, but there's no hard and fast rule on this.

WOW! Does the Artificial Horizon application sub for my 20.18 requirements as well???!?!?!

Two Dogs,
few things. Firstly Sector 3 is divided up into a Sector 3A and 3B. This 5 degree tolerance people are talking about DOES not apply to a Sector 3A.
Sector 1- 110 degrees parallel entry per DAP/JEPP charts means turning onto outbound leg after station passage. Timing commences Abeam aid or wings level- this is critical for keeping the holds/sector entries within the 5 degree tolerance on a CDI for example. All turns in Sector 1 are max AOB due to the proximity of outbound and inbound tracks and thus the intercept inbound is going to be a tight one- ie 45 degrees or less.
Sector 2- 70 degree offset entry. Lets say inbound track is 270 to station, you are coming in from 090. Outbound track is 090 as well, so you would track 30 degrees left (ie 060 if pattern is to the right) Then commence 1 minute timing or per charts. 1 knot of headwind increases timing before turning inbound by 1 second ie if 5 knots headwind 1 mins 5 secs till you turn inbound. Opposite for A tailwind.
Sector 3A as discussed- remaining sector and 30 degrees either side of the inbound track.
Sector 3B.. Remaining sector- put aircrafts wing 90 degrees to outbound leg. Ie if outbound leg is to your right 090 degrees, then track northbound for for 15 secs nil wind, 10 for tailwind and 20 for headwind before turning onto 090. Commence approach as normal.
Critical things in the sector entries are staying ahead of the acft, so anticipate turn by setting new heading 10-15 secs before you turn and keeping a good scan going between AH, ASI, etc.

Make sure you're very clear on the differences between what is required, what is advisable, and what has been handed to you by your instructor simply because that's what their instructor handed them

You're a w anker.
I asked a simple question ... Would anyone like to impart their knowledge to further my (and others) understanding of sector entry, holding patterns and instrument approach techniques.
Most pilots I know are always eager to improve their knowledge and improve their skills.
You of course must be an ACE and have nothing to learn.
WAKE UP W ANKER!

Perhaps you should read the book again....

Name of forum PPRuNE? Perhaps,
So from my understanding that would mean General Aviation Questions and Answers pertaining to "Rumours"....
You guys have way to much time to put links to threads I have commented on, little bit childish really...
