Air India will soon fly over Pacific Ocean to San Francisco, save fuel

New Delhi: Saving significant fuel costs and time, Air India will soon start flying over the Pacific Ocean region for its lucrative direct services to San Francisco from here with aviation regulator DGCA approving the new route.

The regulatory nod comes as a boost for the national carrier, which would be doubling the frequency of its Delhi-San Francisco direct flights to six per week from November.

Air India would also be the first Indian carrier to operate on the Pacific region route where weather conditions and speed of winds would help the airline in reducing fuel burn and the overall journey time.

Officials said the route would be a “win-win situation” for the carrier as well as passengers as it would save crores of rupees worth of fuel costs and also reduce the flying time by up to three hours.

Approving the request from Air India for services through the new route, the Directorate General of Civil Aviation (DGCA) has issued a detailed operational circular.

Some years ago, Jet Airways used to have Mumbai-Shanghai- San Francisco connection service which was stopped.

A senior DGCA official said using the new route would help in saving a lot of fuel as well as time.

In the new route, Air India would fly eastwards to reach San Francisco by crossing the vast Pacific Ocean.

Even though the route would be almost 1,400 km more compared to the current trajectory where the flight flies over the Atlantic, there would be significant saving on fuel and journey time due to powerful tailwinds.

“The Boeing 777-200 LR aircraft, used on the Delhi-San Francisco route by Air India will get only strong tailwinds on its eastward journey and cut flying time by up to three hours,” a senior pilot said.

According to the pilot, the plane, on an average, burns 9,600 litres fuel for each hour of flying.

“Reducing the flying time to SFO from an hour in summer to three hours in winter (due to high tailwinds then) will mean huge fuel saving. So it will be a win-win for fliers and the airline as passengers will reach San Francisco faster while the airline will burn less fuel,” he said.

Explaining how the aircraft would fly faster, the pilot said earth rotates from west to east and winds also flow in that direction.

So, flying west means facing strong headwinds (that decreases an aircraft’s actual ground speed and more fuel is spent), while flying east means getting strong tailwinds which raises the speed and lessens fuel consumption, he added.
