So just how many posters here have flown in a 60 kt wind once let alone regularly??? A rather pointless discussion since whatever the windspeed is, your auto speed needs to be more than it to gain ground into wind, even if that means flying faster than your RFM specified range speed.

If your RFM says 90 kts for range and you are in a 90kt wind then you must fly at more than 90kts if the place you want to land is upwind from where the engine fails.

Equally, the comments about being hot on the landing are irrelevant if you have such a strong wind since you will easily achieve zero groundspeed for touchdown with minimal flare.

The only practical lessons here are that increasing speed in auto beyond recommended auto speed will a. get you further and b. increase your RoD giving you less time in the air but you need to make the decision to go for range early if you are reap the full benefits.
