New FDTL rules: Why DGCA has asked airlines to indicate their implementation timelines

Initially supposed to be enforced from June 1, the rules were deferred due to stiff resistance from airlines. The DGCA has been asked to indicate the likely implementation date in the next hearing scheduled for May 8.

What’s behind the deferment of new FDTL rules?

In a move that surprised many, the DGCA on March 26 deferred the planned June 1 implementation of new FDTL rules. The decision was in line with the directions that the Ministry of Civil Aviation (MoCA) issued to the DGCA on March 22.

The aviation safety regulator announced the postponement without mentioning a new implementation timeline. It allowed carriers to continue following the existing rules until their own schemes are approved, in line with the new FDTL rules.

Airlines had been voicing concerns that implementing the new rules — aimed at better fatigue management through changes like longer weekly rest periods and fewer night landings as compared to the current norms — would result in a requirement of around 20-25 per cent more pilots. They argued that hiring, training, and releasing pilots for duty takes several months.

The FIA had said that carriers would have to cut capacity by 15-20 per cent if the new rules, notified in January, were implemented from June 1. In February, the Federation of Indian Airlines (FIA), which comprises IndiGo, Air India, and SpiceJet, had written to the DGCA seeking postponement of the new rules by a year.

The DGCA, however, had appeared unfazed and kept insisting that airlines must comply by June 1.

Why are pilots dissatisfied?

While the deferment was a win for the airlines, it left a large number of pilots and their associations miffed with the DGCA and MoCA. What seemed to have added to their discontent was the flexibility given to airlines, with the regulator not even mentioning a fresh deadline to comply with the new rules.

On April 1, four cases connected to FDTL came up for hearing before the Delhi High Court. During the course of the hearing, Justice Sudhir Kumar Jain orally mentioned that on the next date of hearing, May 8, the DGCA should indicate the tentative date of implementation.

Flight crew fatigue and exhaustion are seen as major factors contributing to human errors in aircraft operations and can lead to catastrophic accidents. Also, fatigue and exhaustion can be dangerous for the health of the crew.
The DGCA had, in fact, cited a few incidents of pilot deaths ostensibly due to exhaustion while pushing airlines to adhere to the new regulations from June 1.

Across airlines, pilots have been expressing concerns over growing fatigue and stress as a result of being stretched to their limits in terms of flying hours, haphazard and ill-planned rostering, and unusually high crew utilisation levels.

This is because carriers are competing to rapidly expand their networks. Some of these issues were among the reasons behind numerous Vistara pilots calling in sick last week, leading to network-wide cancellations and delays.

What do the new FDTL rules say?

As per the new rules, among other changes, mandatory weekly rest period for pilots shall increase to 48 hours from the current 36. Their night flying would also come down through a combination of extension of definition of “night” by an hour and curtailing the number of night landings allowed to be made by the same crew.

Complying with these rules would require airlines to either hire and train more pilots or scale back operations. Airline officials lament that a hard deadline that gives only a few months to the carriers would impact their operations and business.

Those in favour of expeditious implementation argue that airlines had enough time until June 1, as the new rules were notified early January. Further, they say the carriers were sounded out much before that by the DGCA through the consultative process.

Overview of current FDTL rules in India

The International Civil Aviation Organization (ICAO) mandates that the country where an aircraft operator or airline is based shall establish regulations for the purpose of managing fatigue.

Current FDTL rules in India, issued by the DGCA in 2019, stipulate different categories of maximum flight duty periods per day, based on maximum permitted landings and flight time.

Among other things, the regulations stipulate mandatory rest periods between flight duty periods, in-flight rest periods for long-haul flights, other mandatory rest periods, guidelines for scheduling night operations, and maximum cumulative flight time and duty period limitations per week, two weeks, four weeks, 90 days, and one year. The rules also include special norms for ultra-long-haul flights.

According to the DGCA, airlines are required to establish their own limitations on these counts within the regulator’s framework of fatigue management regulations, which are based on ICAO standards and best practices of the US aviation regulator Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA).

FDTL rules prohibit airlines from asking flight crew to operate a flight if the prescribed time limitations are exceeded. In addition, carriers are not supposed to ask a crew member to operate a flight if it is known or suspected that the “flight crew member is fatigued to the extent that the safety of flight may be adversely affected”.

Airlines are also required to prepare flight crew rosters “sufficiently in advance”.

In addition to training flight crew on fatigue management, carriers are required to maintain a system of fatigue report management, using which incidents of crew fatigue can be brought to light. Such a system should follow a non-punitive and confidential policy, which should also define the response to a fatigue report. Executive responsibility for addressing fatigue management needs to be defined by the airline.

The key reason why there are frequent instances of pilots refusing to operate flights citing fatigue or FDTL norms is that the DGCA’s regulations on FDTL stipulate the responsibility and accountability of flight crews as well.

The regulations expressly prohibit flight crew members from accepting assignments that exceed the prescribed limitations. Additionally, they are also not supposed to perform duties if it is known or suspected that they are fatigued.
