Performance related anecdote from a former pilot

[MediumRareBaku]

I've been trawling the internet in search of information on the YS-11 in order to make more meaningful and helpful bug reports that will hopefully propel this add-on towards a greater level of completeness and accuracy. I've turned up very little, so far, but I found this interesting anecdote regarding performance on PPRuNe from an ex-Piedmont YS-11 pilot that aligns with some feedback I've seen here and on the MSFS forums regarding performance, particularly after takeoff:

I also remember that the airplane's performance was marginal. Most takeoffs were with water. Only on a very cold winter morning with light loads would the skipper elect to do a dry takeoff.

Initial climb rates (after the water was shut off and climb power (14,200 RPM and fuel trimmed to 770 degrees)...hot summer day, max gross weight, both engines...was maybe 500 to 600 fpm. I asked a captain what the climb rate would be if we lost one...He smiled and said, 'Less than 500 fpm.'

So, we did little cruising at 15,000 feet or so. If it was a cold winter day, light loads, long flight, then, maybe, we'd go to the low to mid teens.

I hope this is useful to the devs.

That's what I thought, the Inibuild YS-11 perfomances are too optimistic. As I said on another post, 2200 to 2500 ft/min in the climb at max gross weight is way too high. Thanks for bringing that up.

Hi there,

Thank you for the feedback. Have forwarded this to the team 🙂
