AirAsia India increases aircraft utilisation

AA320

  • One of AirAsia India’s aircraft utilisation has increased to one of the highest in the country.
  • 1 millionth passenger expected to be flown around August 5th.
  • Typical turn around time: 25 -30 minutes.

The airline, which started operations one year ago on June 12th, 2014, now operates a fleet of 5 aircraft from 2 hubs – Bangalore and Delhi. All of the airline’s present flights from Delhi are no less than 2 hours 20 minutes long. Such long flights ensure that the airplanes spend a larger fraction of the flight in air, resulting in higher aircraft utilisation.

One of the airline’s 5 aircraft rotations flies only 2:30hr flights. This rotation covers a Delhi-Bangalore return, and two Delhi-Goa returns. Together, the utilisation on this pattern totals to 15:10 hrs, which is 50 minutes short of the target that the airline had made public, but one of the highest in the country for all domestic operations.

Average utilisation is however at 12:19 hrs, and the minimum utilisation is 11:00hrs. The average turn-around time at the airline is 36 minutes, a figure that is 16 minutes higher than the target of 20 minutes. However, turn around periods of 25 minutes and 30 minutes account for 70% of all turnarounds. There are no turnarounds of 20 minutes. Refer graph below.

Turn_Around_Time

The airline recently added Imphal as a destination, raising the number of destinations to 10. The airline today flies 32 flights a day, deploying 5,760 seats a day and flying around 4,500 passengers daily. Till end May 2015, the airline had flown 716,000 passengers. The airline may fly its 1 millionth passenger on or around the 5th of August 2015.

The airline may add a third Cochin flight in the morning, to provide a well spread out thrice daily service to Cochin from Bangalore. When added, all airplanes will be flying at near maximum utilisation in their rotations. No further growth is possible with the existing fleet.

Aircraft between hubs may be swapped through the night flight I52227 DEL-BLR and I52228 BLR-DEL. Two rotations sync up at the right times to allow for a swap. Until a third Cochin is launched, the airline may use the morning flight I52221 DEL-BLR to swap airplanes.

Ideally, considering that Delhi base has higher aircraft utilisation, the airline may realise a higher fuel saving by deploying two winglet-equipped aircraft at Delhi rather than just one as is the case today. Winglets help realise greater savings on longer flights.

According to the AirAsia Group, AirAsia India, “Overall performance was better than expected with strong loads but is working on keeping costs under check.”

AirAsia India receives its Air Operator Permit; Salaries to increase

Air Asia India receives its AOP at 6:15pm IST. Landmark in Indian Aviation. Article also counters certain incorrect and misleading statements in Business Standard.

AirAsia India received its Air Operator Permit (AOP) today, at 18:15hrs IST. The Chief Executive of the airline, Mittu Chandilya, was at Delhi to receive the AOP.

Tweeted Tony Fernandes, AirAsia Group CEO, at 18:37 IST, “History has been made today in Aviation. Everything has been hard for Airasia but we never give up. Today Airasia India has got APPROVAL.”(sic) That was followed by, “What a battle that was. proud day for me and all airasia all stars”(sic)

This development follows a tweet from AirAsia Group CEO Tony Fernandes, on May 5th: “I think huge week for Airasia. I feel that Airasia India will be approved very soon.” (sic).

AirAsia India concluded its proving flights-the last stage in the award of an AOP-on May 02, 2014. The two day-long proving flights saw the airline fly non-revenue passengers, which included airline staff and inspecting DGCA officers, to Kochi, Bangalore, and Kolkatta, from Chennai, to satisfy a March 2014 revision by the DGCA that requires an AOP applicant to fly a minimum of 5 sectors and 10 hours.

Revised Crew Remuneration

Along with this imminent AOP award today, the airline plans to upward-revise the salaries of its staff. Captains at AirAsia India reportedly are paid INR 1,60,000 (Indian Rupee One lakh Sixty Thousand) less than what IndiGo offers, per month, which results in an annual difference of INR 19,20,000. (Indian Rupee Nineteen Lakh Twenty thousand). This difference in pay was justified with the phase of the airline: non-operational.

The exact increment is unknown, but is believed to be competitive with prevailing market rates. Effective December 2013, IndiGo hiked the salaries of its pilots. Captains received a pay hike of around 15%, while that of cabin crew close to doubled. This salary increment checked the outflow of pilots from the airline.

Few pilots, who had joined AirAsia India early, left the airline to join IndiGo in light of the delays and uncertainties that surrounded the AOP, and the lower remuneration. This long drawn wait had partly demotivated some pilots, but has ensured that only the loyalists and believers are with the company when it starts operations.

However, few pilots left AirAsia India with hesitation, purely due to financial commitments.

Business Non-Standard

Business Standard came out with a piece “Meet AirAsia’s multitasking pilots; they do the cargo, too”, which unfortunately is misleading and partly incorrect.

All pilots can carry out checks known as transit checks, between flights. There is no necessity for an engineer to be involved with this check unless an issue requires rectification. Pilots are usually not authorized to rectify the issue. Pilots in every airline perform a “walk-around” to check the aircraft before departure, to look for signs of visible damage, such as worn tires, or from bird hits. If everything looks fine, no action is required. However, if something is out of place, an engineer’s opinion, involvement and clearance is required.

Such transit checks add an extra level of safety, and are practiced world over.

As far as Cabin crew are concerned, no cabin crew will be expected to perform the load and trim sheet. Errors in the load and trim are unforgivable, with fatal consequences. The cabin crew will perform only those duties which are required of them: cabin safety. Sources in the airline deny the cabin crew being involved with ticketing, and load & trim sheets. However, AirAsia Bhd cabin crew check the boarding passes at the apron entrance, while here, that check might be performed by cabin crew at the entrance to the aircraft, possibly at the foot of the air-stairs.

No pilot or cabin crew will handle the cargo, as suggested by the title of the BS story.

Not all flights have a turnaround time of 30-35 minutes. SpiceJet targets 20 minutes on some of its Q400 flights. Air Costa targets 20minutes on its Embraer E170s and 25 minutes on its E190s. The 25 minutes that AirAsia India targets will, however, be the best for a Boeing 737 or an A320 in India. 20 minutes, however, seems too optimistic.

Indian budget carriers achieve more than 12 block hours, contrasting what was reported. GoAir presently has the best aircraft utilisation in the country, with some of its airplanes flying patterns that start at 05:20AM and land at 12:50AM: a good 19hrs30min every day, picking up a total block time of 14hr15min daily. AirAsia India will not be the only airline to efficiently utilise its aircraft, though with a 20-25 minute turnaround, 16hrs block time is achievable, and may set a record in India.

First A320 in Asia to retrofit its aircraft with Sharklets

TigerAir_SharkTigerair of Singapore, in which Singapore Airlines has a stake of 32.8%, unveiled the first A320 aircraft to be retrofitted in Asia with Sharklets. Five A320s have already been delivered to Tigerair with Sharklet-ready wings, with the retrofit work being undertaken by Sepang Aircraft Engineering in Kuala Lumpur, Malaysia.

Sharklet-ready wings are already strengthened to the necessary levels to handle the bending and twisting forces introduced by the additional aerodynamic surface. The retrofit takes just 2 days for such ready wings. Non-sharklet ready wings will need at least 13 days of work with the sharklet-retrofit kit, which will be available only in 2015.

Jet Blue made “history” in the February of 2013 by being the first operator to perform a production retrofit, on its aircraft N821JB (MSN 5417 which first flew on the 1st of December, 2012). This aircraft was produced before MSN 5428, which is now registered as 9M-AQQ, flying for Air Asia, that had made “history” as the first Sharklet Equipped A320 to be delivered.

Factory fit and production retrofit can be better understood here.

In addition to its retrofitted aircraft, 9V-TRK (MSN 5697 delivered on the 26th of July 2013 to Tigerair), Tigerair will start taking delivery of production-fitted Sharklet aircraft later this year.
