Norway carries out first in-country F-35A parachute braking trials
Snip:-
Norway has completed the first in-country braking trial of a drag chute fitted F-35A on Feb 16, from the Ørland Air Force Base.
The test successfully verified the parachute braking system, a unique feature being developed for the Norwegian F-35As.
It is being added in order to rapidly decelerate Royal Norwegian Air Force F-35s after landing on the country’s icy runways when there are challenging wind conditions.
The chute is housed under a small fairing on the upper rear fuselage between the vertical tails.
