Thrust Reverse Inoperative

Lomapaseo. I too would rather have Thrust Reverse operational than not. I suspect Qantas also has re-thought the "Idle Reverse - Flap 25" preferred technique which was in vogue when they ran a B747-400 off the end of Bangkok. I simply have a difficulty in understanding why "Thrust Reversal" is considered to play only a minor role in reducing speed on landing as distinct from "Inlet Drag". When used, it certainly feels effective. My last employer, onn the B747 Classic rarely used Auto Brake, except on contaminated or limiting runways, and always used Flap 30, unless unavailable, and Max Reverse. Manual braking was not usually initiated until at or below 100 Kts.
