Want services to resume only after at least three major airports in the country become functional

To link countries where no Indian carrier presently flies

Hyderabad International Airport facilitated the first arrival evacuation flight from Kuwait on Saturday.This is the first flight to Hyderabad and is p

In total, around 1,373 Indians returned to their native places from foreign countries on May 10 as eight 'Vande Bharat' flights from Dubai, Kuwait, Muscat, Sharjah, Kuala Lumpur, and Dhaka landed in India.

'Indian aviation cannot resume without at least three major airports being functional. If Delhi, Mumbai, Bengaluru, and Kolkata are shut, there is little chance that airlines will start flying even if the government gives the go-ahead.'

An alternative approach to hard-X-ray photoelectron spectroscopy (HAXPES) has been established. The instrumental key feature is an increase of the dimensionality of the recording scheme from 2D to 3D. A high-energy momentum microscope detects electrons with initial kinetic energies up to 8 keV with a k-resolution of 0.025 Å−1, equivalent to an angular resolution of 0.034°. A special objective lens with k-space acceptance up to 25 Å−1 allows for simultaneous full-field imaging of many Brillouin zones. Combined with time-of-flight (ToF) parallel energy recording this yields maximum parallelization. Thanks to the high brilliance (1013 hν s−1 in a spot of <20 µm diameter) of beamline P22 at PETRA III (Hamburg, Germany), the microscope set a benchmark in HAXPES recording speed, i.e. several million counts per second for core-level signals and one million for d-bands of transition metals. The concept of tomographic k-space mapping established using soft X-rays works equally well in the hard X-ray range. Sharp valence band k-patterns of Re, collected at an excitation energy of 6 keV, correspond to direct transitions to the 28th repeated Brillouin zone. Measured total energy resolutions (photon bandwidth plus ToF-resolution) are 62 meV and 180 meV FWHM at 5.977 keV for monochromator crystals Si(333) and Si(311) and 450 meV at 4.0 keV for Si(111). Hard X-ray photoelectron diffraction (hXPD) patterns with rich fine structure are recorded within minutes. The short photoelectron wavelength (10% of the interatomic distance) `amplifies' phase differences, making full-field hXPD a sensitive structural tool.

Neutron spin-echo spectrometers with a position-sensitive detector and operating with extended time-of-flight-tagged wavelength frames are able to collect a comprehensive set of data covering a large range of wavevector and Fourier time space with only a few instrumental settings in a quasi-continuous way. Extracting all the information contained in the raw data and mapping them to a suitable physical space in the most efficient way is a challenge. This article reports algorithms employed in dedicated software, DrSpine (data reduction for spin echo), that achieves this goal and yields reliable representations of the intermediate scattering function S(Q, t) independent of the selected `binning'.

One of the most challenging aspects of this research is simply studying these insects as they are falling, says Yanoviak, a tropical arthropod ecologist at the University of Arkansas, Little Rock. Small body size, rapid descent, and the long distances that they can fall, make accurate data taking a challenge.

Ornithologists Carla Dove and Storrs Olson used 700- to 1,100-year-old feathers from a long extinct species of Hawaiian ibis to help determine the bird’s place in the ibis family tree. The feathers are the only known plumage of any of the prehistorically extinct birds that once inhabited the Hawaiian Islands.

More targeted aircraft testing and simulation should be conducted to uncover design characteristics in new flight control systems that -- in rare circumstances -- may mislead pilots and result in unstable or dangerous flight conditions, says a new report by a National Research Council committee.

Operation IceBridge, NASA's airborne survey of polar ice, is flying in Greenland for the second time this year, to observe the impact of the summer melt season on the ice sheet. The IceBridge flights, which began on August 27 and will continue until September 16, are mostly repeats of lines that the team flew in early May, so that scientists can observe changes in ice elevation between the spring and late summer.

New research on a major UK airport (Heathrow) has estimated that a night-time ban on flights could produce up to £860 million (1 billion euros) in financial savings over a 20 year period. Economic costs caused by the ban could be outweighed by savings from reduced health costs of sleep disturbance and stress caused by the noise of night flights.

Re-routing flights to avoid the Arctic Circle may help reduce global temperatures and increase sea ice, a recent study concludes. The accompanying reduction in damages from global warming could outweigh the costs of increased fuel usage and operational changes for airlines by 47-55 times.
