Is it protected to fly over a hurricane? A JetBlue airplane flew proper over Fiona

As Hurricane Fiona pulled away from the Dominican Republic, ultimately strengthening into the 12 months’s first Class 3 main storm, greater than two dozen flights in another country’s greatest airport have been canceled. However one made it out.

The flight, headed from Punta Cana to Newark by way of JetBlue late Monday, took off almost 5 hours late, simply after 7 pm It appeared on flight trackers as a lone craft in the midst of a swirling hurricane. It sparked alarm amongst some climate and aviation observers and prompted a query: Are you able to fly over a hurricane?

“I’ve seen the JetBlue flight that apparently went over Fiona and I’ll say that relying on cloud prime heights you CAN fly over a hurricane,” tweeted Nick Underwood, an aerospace engineer who flies into the center of storms as a member of the Nationwide Oceanic and Atmospheric Administration’s Hurricane Hunters to gather very important knowledge.

However, I added, “it’s nonetheless not one thing I might advocate.”

It’s not unprecedented for pilots to steer near or over storms, and it may be completed safely, meteorologists and aviation consultants stated. Pilots can make selections primarily based on climate in session with the Federal Aviation Administration and with their airways’ personal consultants — as was the case Monday night, a JetBlue spokesman stated. The JetBlue flight landed safely at Newark Worldwide Airport simply earlier than 11 pm Monday.

Flight trackers present a number of different JetBlue flights handed by way of Fiona late Monday into Tuesday.

Whereas the FAA supplies some advisory info, it’s finally as much as the airways and their group of meteorologists to find out whether or not a flight is protected sufficient for passengers.

The airline had been monitoring Fiona to find out routes to securely navigate round or above the system, spokesman Derek Dombrowski stated, including that the airline had canceled many flights that might not depart safely.

“Every flight is deliberate by a group of consultants who then monitor progress of the flight and climate repeatedly,” Dombrowski stated in an e mail. “You will need to perceive that when routing a flight each the course and the peak of the climate system are factored into our decision-making.”

The primary risks in flying close to or by way of hurricanes contain lightning, hail and winds, that are strongest close to the middle of a storm and differ in course round it. There’s additionally concern about updrafts—robust vertically oriented blasts of wind current in any sort of thunderstorm. One FAA report from 2011 warns of the opportunity of “violent turbulence wherever inside 20 miles of very robust thunderstorms.”

“An plane when sufficiently excessive sufficient can fly safely above a hurricane so long as they keep away from the person thunderstorms that typically are adjoining to the hurricane,” a spokesperson for the Skilled Pilots Affiliation, a nonprofit group by way of which pilots focus on security, instructed The Put up .

Nonetheless, such situations close by would seemingly not make for a nice flight, stated Randy Bass, a licensed consulting meteorologist who runs Bass Climate Companies.

“I would not have needed to be on that flight,” Bass stated.

Fiona was a Class 2 hurricane with most wind speeds of 110 mph at its core Monday night, in response to the Nationwide Hurricane Heart. Knowledge present the peak of its clouds would have made it tough for any plane to keep away from.

On the time of the flight, clouds across the hurricane’s eye have been as excessive as 45,000 toes, whereas on the outer fringes of the storm they have been between about 33,000 and 39,000 toes, in response to satellite tv for pc knowledge. Typically, Class 2 hurricane clouds attain altitudes from about 33,000 to 46,000 toes.

A mapped monitor of JetBlue flight 1016 from Flightradar24 exhibits the Airbus A320 flew at altitudes between about 30,000 toes and 34,000 toes when it handed close to Fiona.

Even for the Hurricane Hunters, security is a prime consideration when planning routes into and round hurricanes. The group, which gathers knowledge used to higher perceive and forecast hurricanes, flies its Lockheed WP-3D Orion planes into the center of storms at altitudes of 8,000 to 10,000 toes. To discover situations above and round hurricanes, it flies its Gulfstream IV-SP plane at between 41,000 to 45,000 toes, spokesman Jonathan Shannon stated.

Shannon stated it could be tough to estimate how excessive any plane would must be above a storm to keep away from turbulence, noting, “each storm will be totally different.”

Hurricane Fiona battered Puerto Rico Sunday, leaving virtually 600,000 residents with out energy earlier than shifting the neighboring Dominican Republic. Hours earlier than the flight, as much as 20 inches of rain was reported on the jap aspect of the Dominican Republic, the place the Punta Cana airport is stationed, in response to the Nationwide Hurricane Heart (NHC). The NHC additionally warned of life-threatening flash and concrete flooding within the area.
