ETOPS – Extended Range Twin Engine Operations – Understand

Currently, in the aviation industry, twins have become part of the day-to-day operations of crossing the Pacific and Atlantic oceans and in deserted twin aircraft. In this article, I will guide you through this article on how to work in my simple words.

Currently, most twins are already certified to be able to fly normally within an hour in the event of an emergency – not normally a problem in Europe, but in the oceans and airports often closing this can cause problems. It is possible (deserts are also visible as the ocean). A set of rules has been created by civilian aviation authorities to allow / enable long-haul flights with dual-engine aircraft. First, aircraft must be built and manufactured with certified engines. Hours are retrieved and monitored by producers and authorities. The airline must be verified and evaluated before these operations begin.

I give an example in the Atlantic Ocean. Can't fly in this vast ocean using the normal time limit. It can be transferred by implementing a two-hour suspension (ETOPS-120 is rated when entering the ETOPS-180 only 120 minutes of ETOPS experience 1 year later) but many locations have failed. They must be exceeded because they are outside the range of airports / airports if ETOP-120 is used). At least ETOPS (138 min) has introduced to solve this problem so that any airline can cross the Atlantic.

One more example, we take a flight from the United States to Hawaii. At approximately 6 hours on a flight size from Hawaii to the USA, any airline requires a 3-hour confirmation. This is why ETOPS-180 was introduced. Therefore, if ETOPS-180 is not certified, it should use the long route north of Greenland and Iceland.

Examples of ETOPS ratings are as follows: –

  • ETOPS-75
  • ETOPS-90
  • ETOPS-120/138
  • ETOPS-180/207 (95% of the earth's surface)

p / s You know ETOPS famous acronym = "Engineers turn off, passengers swim" and "engine turns or passengers swim".
