Why Flights face turbulence?
Subject: Geography
Section: Climatology
Context: Directorate General of Civil Aviation (DGCA) on Monday constituted a “multi-disciplinary team” to investigate the incident that caused serious injuries to several passengers after SpiceJet’s Mumbai- Durgapur flight encountered severe turbulence.
Concept:
- There are at least seven kinds of turbulence that an aircraft can run into. These include:
- On a regular basis, Aircraft undergo some form of turbulence and pilots are trained to deal with these. However, there have been several instances when turbulence has brought down modern jetliners. Even in these cases, while intense turbulence has been the main cause of an accident, several other factors—such as lack of proper training, poor dissemination of weather or wind related information — have contributed to the accident.
- During descent, if the aircraft experience severe turbulence, the vertical load factor varies from +2.64 G and 1.36 G. During this period, the auto pilot gets disengaged for two minutes and the crew manually fly the aircraft.
- G refers to g gravitational force equivalent, which in normal flying conditions is 1 G. A negative G value indicates that the aircraft was accelerating downwards faster than the rate of natural free fall, giving the feeling of weightlessness.
- Airflow Disruption can be of four varying intensities. These include:
