India's Civil Aviation Minister K. Rammohan Naidu has been passionately telling the arithmetic since the Cabinet cleared Modified UDAN in March and he restated it in Ahmedabad on 1 September. India went from 74 airports in 2014 to 166, the next decade is meant to add 100 more from unserved airstrips, plus about 200 helipads, on an outlay near ₹30,000 crore against a scheme envelope of ₹28,840 crore through FY36. The design is scheduled regional connectivity's viability-gap money for airlines, three years of operations-and-maintenance support for hundreds of small fields, a challenge mode with states, priority for hills, islands and the Northeast. That is a passenger-subsidy story. It is not a plan for what the same strip does on the six days the scheduled flight does not come.
The fields that will survive are the ones that can earn a second life as mixed-use aviation centres. An air ambulance, a flying school, an agricultural spray contract, a charter that lifts a mining crew, a disaster-relief parking slot and a Pawan Hans or state helicopter do not need a mini-Delhi. They need a serviceable runway, fuel or a bowser arrangement, a fire crew that can open the field, a fence that keeps cattle off the threshold, and a room that can file a flight plan. Modified UDAN already nods at helipads and indigenous metal. It still scores success as airline departures. The last UDAN decade left routes that lived only as long as the VGF. A Himalayan or island airstrip that cannot hold a medevac at night or a training circuit on a weekday will go dark again when the subsidy tapers. Navi Mumbai and Jewar will not save those strips. Mixed use will. The test for each of the 100 is not whether IndiGo will sell a fare. It is whether a charter operator, a DGCA-approved school and an EMS provider would base a machine there if the scheduled frequency died.
None of that opens without people. A small licensed aerodrome is not a terminal manager and a windsock. Before the first public flight it needs aerodrome rescue and fire fighting to the category the largest expected aircraft demands, wildlife control, electricians who can keep the PAPI and the generator alive, CNS technicians for navaids or at least a maintained comms link, security screeners if passengers are processed, a meteor observer or a pipeline to a Met station and either a tower or a published AFIS arrangement that ATC and the DGCA will accept. Add a duty officer who can close the field in fog.
India’s pilot pipeline is the part of the workforce the ministry already discusses. Firefighters, CNS techs and wildlife men are not trained in the same schools and they do not stay in a district town on metro wages. One hundred new fields is a multiplier the announcement has not published, even a lean Category 4 or 5 operation is a roster, not a ribbon. Retention is the second half of the sum. A technician who can work Bengaluru will not remain in an unserved airstrip unless housing, leave and a career path exist. Until MoCA and AAI put a staffing template and a training-seat count next to the Rs.12,159 crore airport-development line, the 100-airport map is civil works. It is not an opening certificate.
The useful policy is therefore narrower. Rank the proposed strips by mixed-use catchment, hospital, flying school, agri belt, energy site, pilgrimage, island not only by who bid a UDAN route. Publish the minimum safe roster for each category of field. Tie O&M support to keeping the strip open for non-scheduled traffic, not only to protecting a three-times-weekly departure. The country can afford 100 more points on a map. It cannot afford 100 more terminals that wait for a subsidy and have nobody qualified to fight a fire when the air ambulance calls.
