Total electrical failure on 787s? The ac design replaced a lot of mechanical controls with electrical ones to save weight. To provide adequate redundancy, six 250 kW generators are used. Even if all six failed, a lithium-ion battery supplies power for six seconds. 1/n Six seconds is enough time to deploy a Ram Air Turbine (RAT) that can deliver adequate electrical power needed to keep engines running and avionics operating to ensure a safe landing at the nearest airport. Sounds good on paper.

Thread on #CDSBipinRawat helicopter accident. #CFIT #SpatialDisorientation Human Factors in aviation accidents are attributed to unsafe acts that are either Errors or Violations. Errors could be decision/ skill-based/ perceptual. Spatial Disorientation (SD) falls under perceptual error.

An aviator’s perspective: CFIT is real. Can happen to the best of pilots depending on contributory factors. Is it ‘Pilot Error’? Straight answer is ‘No’. Read on to know more… If an aircraft flies into terrain due pilot error, it’s uncontrolled flight or UFIT and not CFIT. Therein lies the subtle difference. Why does CFIT happen? Many reasons… could be disorientation, LOSA (Loss of Situational Awareness), Subtle incapacitation, Nav Aid malfunction….

A thread on Russian Bombs.... Nomenclature used on Russian Bombs could be confusing even for fighter pilots who drop them regularly. Here's a thread on some basics.... Most Russian bomb nomenclatures would have AB embedded in it. eg: FAB, OFAB, ODAB, BetAB, KAB etc. AB stands for Avia Bomba which translates to Aerial Bomb.
