Descent Rate Resulting in Blown Tires

[Buzz313th]

I know this topic has been mentioned many times before, but I wanna take a stab at it.

Lately I have been flying a Cheyenne into some short strips with over 50 foot obstacles. More often than not the approach procedure
requires a steep descent angle (High Descent Rate) with a last second flare to touchdown smoothly. Almost every single landing I have
blown tires at St Barts made by Fly Tampa. I am flaring correctly and I am touching down at a safe descent rate. I know this because I am
watching the replays. Either way I am still getting blown tires.

I have come to the conclusion that what may be going on here is this:

The FSPX calculation to determine if a tire is blown due to excessive descent rate at touchdown is being calculated or sampled a few
seconds before actual touchdown or, it is taking the descent rate from the vertical speed indicator, which is wrong, since most VSI's are
trend instruments and will not show a change for a few seconds. My point is that, my descent rate at touchdown is slow, less than 50-
100 FPM on these short field landings and I am being penalised for descent rates calculated before touchdown.

Dan, can you please confirm whether I am barking up the correct tree here?

Does your end of flight report actually state that it was the descent rate that blew your tires? Blown tires is actually one of the 'random failures'
that you'll encounter when you have failures set.

Yes... But blown tires are randomly generated due to high descent rate....

Depends what aircraft you're using; some appear to be far more sensitive to blowing tires due to descent rate.
