Correct answer to question 140 (Air Brakes): Downshift further if possible and use an escape ramp if one is available, rather than continuing to press harder on the same brakes

Why

Fading brakes are already losing effectiveness from heat, so downshifting further to use engine braking, and heading for an escape ramp if available, is safer than continuing to rely on brakes that are failing.
