No triple 7 pilot in their right mind would have used T1 intx at the gross weight required to fly MIA-DOH!!
That the other three pilots agreed to it is incomprehensible.
I think that’s a little harsh. With the large variation in TORR between F5 derated and F20 full power, it’s not a given. With a headwind it might even be OK. We don’t use OPT on our T7s but I can see the issue with /T1 and #T1.
Had any of the crew operated that sector before and were familiar with MIA? Does it say 2600m TORA at the T1 intersection? Like others say, this looks like a classic design/HF issue where it was bound to happen eventually and these guys copped it. Will be very interested in the report when it surfaces.
