Spitoon,
If you have look at the holding pattern design criteria, you may very well be surprised.
The holding patter protected areas don’t look anything like a holding patter shown as a racetrack, but does take into account quite extreme possible winds.
On an ATC radar, it is not to hard to work out who is using the FMCS system of current aircraft to track the racetrack, their ground track actually looks something (very) like the neat little diagram on the chart. The rest are all over the shop.
Many pilots have been using all sorts of wind compensation for years, but this is largely disregarded in working out the protected areas. For my money, keep using them, you will stay closer to the racetrack, but you don't have to.
The bottom line is ----- all FMS aircraft will say well within the protected areas, some airecraft will exceed 30 degrees of bank on autopilot to maintain the FMS track. Users of the antiquated braincrank systems, short of really gross miscalculation and equally gross flying, will be quite safe.
Seems to me that whoever established the original design criteria had a remarkably practical approach to the real world.
Tootle pip !!!
