Sorry I don't know -
SEN has had the runway specially grooved I gather - is that so>?
Edit - looking at the spoilers - the SFP allows the spoilers to deflect up to 60 degrees
which in the video looks like it....
The Short Field Performance improvement package was developed to allow GOL airlines to operate their 737-800s into the 1,465m (4,800ft) Santos Dumont airport.
The mods enable weight (payload) increases of approx 4000kg for landing and 1,700kg for take-off from short runways.
It includes the following changes:
Flight spoilers are capable of 60 degree deflection on touchdown. This compares to the current 33/38 degrees and reduces stopping distances by improving braking capability.
Slats are sealed for take-off to flap position 15 (compared to the current 10) to allow the wing to generate more lift at lower rotation angles.
Slats only travel to Full Ext when TE flaps are beyond 25 (compared to the current 5). Auto slat function available from flap 1 to 25.
Flap load relief function active from flap 10 or greater.
Two-position tail skid that extends an extra 12cm for landing protection. This allows greater angles of attack to be safely flown thereby reducing Vref and hence landing distance.
Main gear camber (splay) reduced by 1 degree to increase uniformity of braking across all MLG tyres.
Reduction of engine idle-thrust delay time from 5s to 2s to shorten landing roll.
FMC & FCC software revisions.
The SFP package has now become an option on all 737-800NG and standard on the 737-900ER
