Delhi did not close the airport for BRICS. It split the sky. About 35 special aircraft, a mix of presidential jets, delegation charters and support freighters, were planned across Palam, Indira Gandhi, Noida International and Hindon, with Safdarjung almost shut and Jaipur and Lucknow held as overflow. Up to 12 slots at Air Force Station Palam. Twelve bays at IGI, six widebody and six narrowbody. Twelve more at Noida. Roughly ten additional stands elsewhere. That is not a summit greeting. It is a parking spreadsheet designed so a head-of-state arrival does not steal a commercial contact stand at Terminal 3 during a 1,400-flight day. Five or six principals were meant to use Palam’s technical area, where the aircraft never meets the passenger terminal and the convoy route can be chosen after the wheels stop. CISF briefed that 70 to 75 percent of participating countries would bring one dedicated aircraft and 10 to 15 percent two. The rest of the 35 were support metal, not red-carpet metal.
Noida was the part of the plan that will matter after the family photograph. Three Russian military aircraft, including at least one Ilyushin Il-76, landed at Jewar as an advance party, the first foreign aircraft the new field had accepted. Putin still flies an Il-96. The Il-76 is the truck that brings the cars, the comms and the security kit. Using Jewar for that load kept a heavy transport off IGI’s already reserved widebody line and gave Noida a live test of international handling, fuel, security and parking before scheduled foreign passenger flights begin. Whether that validates Jewar as a permanent VVIP, diversion and cargo-support airport depends on what AAI and NIAL publish next, not on the landing photograph. A one-off military arrival is not a certified international operation. It is proof the runway and the apron can take the weight. BCAS still has to sign the passenger terminal. The useful question is whether those 12 reserved Noida bays become a standing overflow product for G20-scale events, disabled-aircraft recovery and cargo surge, or whether they go back to being empty concrete once the Il-76 leaves.
The commercial cost was real and mostly unpaid in public numbers. DGCA barred non-scheduled operations inside 300 kilometres from 11 to 13 September. Scheduled airlines kept flying. Controllers slipped many of them 10 to 15 minutes so a regular departure would not occupy the same window as a special inbound. Climbing traffic had to be at Flight Level 290 by 200 kilometres from Delhi. Arrivals could not start down from that level until the same ring. Flying schools in seven states stopped. Light aircraft, long-range drones and, closer in, every short-range unmanned thing were frozen. Safdarjung closed except for specified IAF, BSF and NSG helicopters. Rohini Helipad shut. IGI expected an extra 40 to 50 movements on top of the normal 1,400. What AAI, DIAL, NIAL, AERA and DGCA have not yet released is the audit the city actually needs. How many minutes of delay accrued on 11, 12 and 13 September. How many diversions. How much extra fuel the FL290 profile burned. How many widebody commercial positions were frozen for three days. How many business-aviation flights were refused. Without those figures, 'no disruption to scheduled flights' is a political sentence, not an operations result. The lesson sitting in the parking plan is already clear. Delhi-NCR can run a four-airport VVIP system if Palam takes the principals, IGI keeps the banks, Noida takes the heavy support and Hindon and the ring airports take the overflow. Making that a standing playbook, with published delay codes and a pre-agreed overflow tariff, is the work that should start on Monday, not the next time 35 special aircraft ask for the same sky.
