Ground Aircraft - Now, the company has shown the first video of its prototype, a quarter-scale Seaglider with a wingspan around 18 ft (5.5 m). Embedded below, the video shows the machine in slow taxi, fast, smooth hydrofoiling, takeoff, wing-borne cruise and landing.
5. A plus (+) cable becomes disconnected and drops down making contact with a metal grounding surface. If you're lucky, a fuse will blow, or a circuit breaker will pop. The worst case scenario? Wires get hot and burn, smoke fills the cockpit, and avionics self-destruct.

The breakage of a P-lead in service can take place most any time due to the effects of ordinary vibration and/or clumsy maintenance. So. . . Unthinkingly turning the propeller, even a little bit, without assuring yourself that the mags are grounded, can turn the act into a lethal event.
The Financial Cost Of Aog
When asked for comments about the grounding of at least 50 planes of the two carriers and steps taken to address the issues, a P&W spokesperson said it expects the "pressures to begin to ease later this year" but did not mention about the number of aircraft.
that have been impacted. The result, claims Regent, is pretty remarkable: a quick, quiet, comfortable, 14-seat electric coastal transport capable of covering distances up to 180 miles (~300 km) at speeds up to 180 mph (300 km/h) with zero
emissions – using today's commercially-available batteries. It should be cheap – half the operating cost of an aircraft, and lightning-fast, at some six times the speed of a comparable boat. And the concept is scalable, too;
the old Ekranoplans became more efficient with size, and these should, too. Regent has its eye on versions up to at least 150 passengers. The wires used to connect the magneto should be shielded type cables.

(I hate to use the word "cable" because in my mind it conjures the image of the heavy stranded cables used in cranes or to support structures like the Golden Gate Bridge.) If yours is an all-metal homebuilt, its electrical system can be made up of single-wire circuits.
That is, only one wire will be needed to magically connect each electrical unit or device to its electromotive force. . . the battery or alternator. However, it is not so lopsided a comparison when you consider the fact that most of your single-wire circuits will still require a terminal connection to ground.
So, unless a unit is automatically grounded through its case upon installation, at least a short connector cable will be required to the nearest ground terminal block or stud. A source at the no-frills carrier said that 25 aircraft are on the ground out of the current fleet strength of 61. The airline expects deliveries of three planes as well as 17 P&W engines in March, the source added.
"Like many in the industry, we are experiencing global supply chain challenges, which are limiting the availability of structural castings and other parts and we are working mitigation strategies with our supply base and expanding MRO (Maintenance, Repair and Overhaul) network capacity.

3. An electrical unit is not grounded. Some electrical devices (solenoids, relays, senders, etc.) are grounded through their cases. If the unit is not attached to a metal grounding surface, a separate grounding connector must be installed to the nearest electrical grounding point.
"For the current fiscal year ending March, we have anticipated 17 percent growth, probably we will end up at the high range of that number. That is a number speaking about the size and ambition of IndiGo," he had said.
The magneto P-lead cables and most of the other wiring in a homebuilt are rarely more than 5 feet in length so voltage drop in a cable is not usually a factor to worry about. Actually, most homebuilders are prone to using larger cables than necessary in their electrical system.
For that matter, they try to get by with a minimum of different wire sizes. But airlines are not the only ones affected. Along with passengers, flights carry precious cargo and shipments across the world everyday.
Reasons For Grounding
Our mail system relies on planes traveling when they are scheduled. With shipping times being promised at just a few days, delayed flights can result in consumers receiving delayed products and businesses gaining unhappy consumers. While not the businesses fault, consumers will look to them with irritated expectations and diminished trust.
Whether or not you fly regularly, the aviation industry still affects you. A senior government official told PTI that there are at least 25 aircraft each of IndiGo and Go First that are on the ground due to P&W engine problems, and the engine maker is not able to ensure timely deliveries on account of supply chain disruptions.
On the other hand, the shielded interconnecting cable used between a strobe light unit and its power supply is normally terminated (grounded) at one end only to reduce to a minimum potential radio noise due to RF radiation.
Usually, it is more practical to ground or terminate the shield at the power supply end. However, do not terminate both ends. At least, that is the advice offered by the manufacturer of Whelen strobe light equipment.

The spokesperson for IndiGo, which operates around 1,800 flights daily, said that while the supply chain issues represent a constraint, they have not halted its growth. "We are bullish on the market opportunities and will continue to add flights in existing and new geographies in future".
A grounded aircraft not only causes a huge inconvenience to passengers, it can also be a big financial burden on airlines. Among other things, there are storage fees, the cost of expedited parts, and hotel or flight vouchers for passengers stranded from a delayed or canceled flight.
In a 2010 study conducted by the FAA and the National Center of Excellence for Aviation Operations Research, or NEXTOR, flight delays in 2007 were estimated to cost airlines roughly $31 billion. Part of this figure is the high purchasing and leasing cost of planes.
When a flight is delayed or grounded for long periods of time airlines cannot recover costs through ticket sales. This problem is so large and widespread, insurance options have been created specifically for airlines to help recover costs from AOG situations.
"We continue to receive new aircraft and also a supply of refreshed engines, albeit slower than what are required. Some of the other measures being evaluated include slowing down redeliveries through lease extensions, exploring the reinduction of aircraft into the fleet, and evaluating the wet
lease options within the regulatory guidelines,” the spokesperson said. Regent has already raised the $18-odd million it needs to take the next step: building a full-scale prototype with a 65-ft (19.8-m) wingspan for manned trials, which it hopes to commence in 2024. It hopes to be
in mass-production, and for the Seaglider to be taking paying passengers, by 2025. Because of the burden AOG can put on all players involved, Proponent priority services is ready to act as the only crisis management tool needed in those crucial hours.

Against the backdrop of continuing engine woes, a senior official at one of the budget carriers on the condition of anonymity told PTI that there is also a thought of changing the engine supplier for its next order to overcome the persistent problems with P&W engines.
It's all shot in fine weather and relatively smooth seas, but it's certainly impressive to see how gracefully these things hydrofoil. Takeoff and landing look a touch more exciting, and indeed we're interested to learn what the experience is like in the cabin as they hit the water and slow down – but it'll likely be a friendlier landing than that of a seaplane, and
there are plenty of those in service. AOG is an aviation term meaning Aircraft on Ground. When an aircraft is in need of immediate AOG services, this means that the plane has been grounded and is unable to reenter rotation until it is approved for flight.
While AOG can be caused by a myriad of reasons, including flight scheduling conflicts or weather, sometimes in-service planes can also be grounded for mechanical reasons. When this is the case, commercial aircraft cannot return to service until they are repaired, inspected and approved.
Everyone across the aviation industry will agree, getting a plane the proper service to get off the ground and back in the air is a top priority. That would be the hydrofoils. Regent's Seaglider is designed to taxi slowly like a boat, with its V-shaped hull/fuselage in the water.
As it speeds up for takeoff, it rises out of the water on a set of hydrofoils. This takes the cabin up out of the waves, making it glide smoothly above the surface for a comfortable ride.
It also vastly reduces drag, and thus also the energy required to push through the water, so it uses much less energy reaching takeoff speed for wing-borne flight. The hydrofoils fold out of the way once the aircraft is out of the water, and descend again for landing.
In most aircraft, you do this by connecting one end of a heavy cable, or metal grounding strap, to some conveniently located bolt on the engine crankcase. The other end of the grounding strap should terminate on some solid part of the aircraft's firewall structure.
Regent has released a video of its remarkable Seaglider prototype in flight testing. The first machine to combine the efficiency advantages of ground effect and hydrofoiling in a single design, it promises revolutionary speed and range in coastal areas.
That's an ambitious timeline, but Regent has brought serious money on board, and has already demonstrated its ability to move at breakneck pace. And it has a considerable leg up over next-gen aircraft, such as electric VTOL air taxis, by virtue of the fact that it can certify this thing as a WIG maritime vessel, avoiding the bottleneck of FAA type certification.

. like noise in your radios. "People have been attempting to make wing-in-ground effect vehicles viable for 60 years, and in 15 months we have gone from a drawing on a napkin to the first successful flight."
said Mike Klinker, Regent CTO and co-founder, in a press release. “Regent is the first team in history to overcome the deficiency of low wave tolerance with past designs by combining high-speed hydrofoils with ground-effect flight – a crucial innovation that will revolutionize coastal transit.
No vehicle in history can match the combined wave tolerance and speed of our seaglider.” Given how vulnerable our data has become due to the easy availability of the internet, it has become simple for attackers to access our data and use it to their advantage.
Especially during the festive season when people go on a buying spree to purchase the best gifts for their lover, which allows their data to get more exposed, thereby making it easy for hackers to conduct crimes.
Earlier this month, Tata Group-owned Air India placed an order for 470 planes with Airbus and Boeing. However, P&W has not been chosen to supply engines for any of these aircraft and the engines are to be supplied by GE Aerospace, CFM and Rolls Royce.
More than 50 planes of IndiGo and Go First are on the ground due to Pratt & Whitney engine woes amid persisting supply chain headwinds, forcing airlines to explore wet leasing of aircraft and other options to minimize disruptions, according to officials.
When aircraft are awaiting simple parts, those parts must be driven, flown, sailed, and even hand-carried to the aircraft in the most efficient pattern to minimize time on the ground. AOG services require time-mapping, landscape and navigational prowess, and systematic operations.
With additive manufacturing on the horizon for the aviation industry, waiting time for parts may be shortened or almost removed, but for now, the preparation of AOG services is vital for airline success.
