4. Earharts own system of flight planning, seen previously, to achieve a figure for the duration of the flight seems to be quite simple: Divide the distance by the planned cruising speed in still air, nil wind conditions, of 150 Statute Miles per Hour (Smph), and adjust for what wind information is available. Howland Island is an uninhabited island located just north of the equator in the central Pacific Ocean at 048N 17638W, about 3,100 km (1,675 nautical miles) southwest of Honolulu. High Frequency (HF) radio calls emitted by the Electra are claimed by some to show that signals heard at Strength 5 (S5), mean that the Electra was on top of or very close to the receiving station. [31], Public entry to the island is only by special use permit from the U.S. The main reason for the position of the Ontario was, I suppose, as a Half-way Beacon using the glimmer of its lights, but strangely the Ontario reported that it was not using any special lightssomething which would have been akin to a dim lamp at a thousand paces. Various total content-amounts of gasoline are stated for the flight. After the take-off, the Velocity required for Steady Horizontal Flight at best Coefficient of Lift 0.665(found from the Lift/Drag Polar of Lockheed Report 487 Page 24)at best Lift to Drag Ratio of 11.85(from the corrected Page 30 of Report 487), is 203 ft/sec or 137 Smph, so we have a buffer of 11 Smph over our no go below of 126 Smph, if we maintain 137 Smph. The USS Ontario seems to have wandered off to the east in line with the direction of the wind of 20 Knots (23 Smph) which the Ontario deck log records as from 082 degreesan easterly wind. Answer . The Republic of Kiribatis Line Islands, which have a time zone of +14 hours UTC, are on the far east of the earth. The Flight Planning done for this hypothesis is in Statute miles (Sm) as units of distance and in Statute Miles per Hour (Smph) as speeds per hour. As was our custom, we had a drink in the evening 90 degrees F, and 95 percent humidity made it that way. High, very high, on Earharts agenda would be the retention of the Electra. The U.S. claims an Exclusive Economic Zone of 200 nautical miles (370 km) and a territorial sea of 12 nautical miles (22 km) around the island.. Time zone. There is no way that Noonan could know the correct position of the Ontario unless he took a starshot close to the position of the ship and he has no way of knowing what the up-to-date log position of the ship was or of the surface wind conditions. E. Netcher of the Isabella informed Captain Taylor of its discovery. In the knowledge that the wind had achieved a strength of 26 mph from the east at Nukumanu Island, as proven by Earhart broadcasting the strength and the Vector Diagram proving the easterly direction (and bear in mind that there was a forecast of 23 Smph ENEafter the Ontario by the Meteorologist at Pearl Harbour but which Earhart did not receive before she left Lae), then it would be sensible for Earhart and Noonan to have a revised ETA upon meeting that wind. - to help you get the most out of your next trip. The quickest flight takes 40h 40m and has one stopover. Up until a year ago I chatted to him about Amelia many times and he recorded the views Ill relate to you. Rome2rio is a door-to-door travel information and booking engine, helping you get to and from any location in the world. The climate expectancy was good, with expectations of drier weather from April to September( it still rains heavily but for a shorter time, within this period, but is described as drier). UTC is Coordinated Universal Time, GMT is Greenwich Mean Time. Howland Island was uninhabited when the United States took possession of it in 1857 through claims under the Guano Islands Act of 1856. Use our World Clock! Fish and Wildlife Service and it is generally restricted to scientists and educators. Was There Any Localised Knowledge of Weather Patterns for the South Pacific? ) Two days later, shelling from a Japanese submarine destroyed what was left of the colony's buildings. We dont know. It only increased by 5 Smph because the headwind was increasing. In the event, this non-stop flight was never attempted neither east to west nor west to east but the fact remains that the strip map was made for Flight Planning purposes and therefore under certain conditions the flight could be made. The reason for this time difference is that one end would have a time of +12 hours UTC while the other would have a time of -12 hours UTC, which would mean a difference of 24 hours on a number line. Continuous Cruise Power setting, it too does not fit. Nowhere near the actual TAS, and still not correct. The "Z" is for "zero", and "Zulu" is the two-way radio pronunciation of "Z". We are talking here of radio sets in 1937 and we are hearing Earhart over a crackly radio transmission on High Frequency (HF) radio, with interference from atmospheric activity and also, the Australian radio operator, Harry Balfour, is hearing the American pilot, Amelia Earhart, speaking in a Kansan accentand a low monotone voice. A/C Empty weight+Unusable Fuel+Oil+Equipment, APS Weight+Fuel+Crew and Baggage (Plus Passengers if any), Brake Horse Power also referred to simply as H.P., A Power Setting made to produce a Cruising Speed. 5 metres (16 feet) United Nations Location Code. Rome2rio also offers online bookings for selected operators, making reservations easy and straightforward. It is more likely, as other authors write, that Earhart said making 140 without giving a definitive of knots or Smph. As always you can unsubscribe at any time. 2. The 0718 GMT point near Nukumanu to the USS Ontario Climb to Cruise height. In these early Direction Finders this can lead to an uncertainty with the possible bearing angle being ahead of the aircraft or behind the aircraft. I can offer a hypothesis of what happened but it will probably never be known for certain what happened to cause a failure to reach Howland because of a lack of pertinent data. It passes through the Pacific Ocean, roughly following the 180 line of longitude and deviating to pass around . In the two days at Lae, she tried to learn pidgin English and talk to the [natives], and about her ability wherever they landed to take the cowls off the engines and do a Daily Inspection. * Adjusted for Daylight Saving Time (15 places). Take Kiribati itself, for example. Lockheed had flight-tested the Model 10E in the standard passenger configuration in 1935 and produced Lockheed Report 465 and Clarence Kelly Johnsons name features strongly in that report. The United States took possession of the island in 1856 under the Guano Islands Act of 1856 and from 1886 to . Subsequently, Alfred G. Benson resigned from the American Guano Company and together with Netcher, Taylor and George W. Benson formed the United States Guano Company to exploit the guano on Howland Island, with this claim being recognised under the U.S. So, they changed the international dateline so that all of their islands are on the same side which added two more time zones on one side. It actually turns out that my MS Excel plot of the flight, only requires a 26 Smph headwind strength at 10,000 feet to hinder the Electra in reaching the Ontario. [1] One of the atolls in the group, Kiritimati, has the largest land area of any atoll in the world. Approximately. She adds that she will: whistle into mic [the microphone]. P.S. The U.S. Pacific Remote Island Area (PRIA) includes seven islands, atolls and reefs in the Central Pacific that are under the jurisdiction of the United States. Again, using the law of averages as an illustration, if the start speed at Nukumanu is 124 Smph, then the end speed at Howland and the USGC Itasca has to be 158 Smph, the wind being constant. We talked a lot about his experience as a Captain on the China Clippers flying from the West Coast to China, and he told us of his expertise in Astro-navigation, amongst other things. The Thrust required to move the aircraft forward and upward through the air is a combination of the Drag of the aircraft in SHF plus a quotient for the weight extra pounds caused by the angle of climb. Because of the overweight condition (overweight meaning above the Standard 10,500 lbs AUW of the Electra), the Electra could not be aimed skyward to climb rapidly, the climb was a drawn-out affair at a low angle of climb. [17], Chain of eleven atolls and low coral islands in the central Pacific Ocean. At that 888 Horsepower total, the Electra can climb at 300 ft/minute and reach 7000 ft in 23 minutes but at the cost of a large amount of fuel used in the climb. E. Netcher of New Bedford. A telegram from Kelly Johnson of Lockheed to Earhart states that 900 USG is ample for this flight and the 40% excess range. The refuge now includes 648 acres (2.62km2) of land and 410,351 acres (1,660.63km2) of water. Monday, January 16, 2023. Howland Island was designated as a scheduled refueling stop for American pilot Amelia Earhart and navigator Fred Noonan on their round-the-world flight in 1937. This Anchorages of the Solomon Islands chart was obtained for me by an ex-U.S. Navy Officer who found it listed in the files of the U.S. Navy Hydrographic Office where it had been printed in 1914 and revised and printed again in 1921, so this chart was available to Fred Noonan from a U.S. source. 793 Esplanade [36], Howland Island seen from space in April 2007, Location of Howland Island in the Pacific Ocean, Quote: Thursday, July 1, 1937 Howland Island was using the 10+30 hour time zone the same as Hawaii standard time", Pacific Remote Islands Marine National Monument, American Equatorial Islands Colonization Project, List of lighthouses in United States Minor Outlying Islands, "United States Pacific Island Wildlife Refuges", "Howland Island National Wildlife Refuge", "United States Pacific Island Wildlife Refuges. A 1942 eyewitness description spoke of "a low grove of dead and decaying kou trees" on a very shallow hill at the island's center. That has to be incorrect and what Balfour should have recorded was 157o East, which coupled with the Latitude gives a PR over the island of Choiseul in the Solomon Islands group. unless Amelia Earhart magically drops from the heavens and lands, it won't make much difference. Its guano deposits were mined by American companies from about 1857 until October1878, although not without controversy. Rome2rio's Travel Guide series provide vital information for the global traveller. The clocks in the world are under the regulation of the Coordinated Universal Time (UTC), which is not adjusted for daylight savings. You may think that the aircraft is close but it could be a thousand miles away. Earharts upper Vee HF aerial signal radiation may have been reflected off the atmosphere and allowed for a stronger reception. Areas with +13 hours UTC will have a difference of 25 hours from areas with -12 hours UTC. Their track out of Lae went almost due east on 092o True to reach the landmark of Mount Maetambe, 686 Sm from Lae in (or close to) a time of 5 Hours and 18 Minutes (5.3 Hours) delivering an average G/S of 129 Smph. Victoria Aust. Great Britain/United Kingdom is one hour ahead of UTC during summer. 1. Thomas Bederman, one of the two survivors, later recounted his experience during the incident in a March 9, 1942 edition of Life. [18], In the late 19th century there were British claims on the island, as well as attempts at setting up mining. To apply the Law of Averages is hypotheticalbut it illustrates the point, the Electra must increase the Groundspeed to be on Howland at 1912 GMT. ", One person joked: "Imagine working on both islands. Johnston Atoll: Both the US and the Kingdom of Hawaii annexed Johnston Atoll in 1858, but it was the US that mined the guano deposits until the late 1880s. At this 6:35 hour point and according to the Lockheed Long Range Plan, the Electra should have used 413 USG. It must always be remembered that this flight was in 1937 and when reading about this flight, the reader should cast the mind back into an age which lived without the miracle of the internet or mobile phones, where super-technology that we know today was in its infancy. They have a land area of 193 square miles (500 square km) and are divided into Northern, Central, and Southern groups. To reach Howland now, with this data of a G/S of 118 Smph at the Ontario, the new ETA at Howland at this current G/S over 1272 Sm, is 2124 GMT or 10.8 hours more flying. Looking for the current time? Itascatown was a line of a half-dozen small wood-framed structures and tents near the beach on the island's western side. On my plot with the G/S of 118 Smph each hour (which has been decreasing) since leaving the Ontario, at 1912 GMT after 8.6 Hours the Electra would have covered 1015 Sm and is still 320 miles from Howland Island. This means that from a start G/S at Nukumanu of probably 124 Smph, the Electra has to accelerate into the headwind with at least a 16 mph every hour acceleration rate to achieve an end speed at the Myrtlebank of 176 Smph G/S. This is possible because the International date line is not a straight line. If you are regulating to the Best Lift-to-Drag Ratio TAS with a headwind of 26 Smph you are only doing 118 Smph Groundspeed at the Ontario as Noonan would have known; Earhartalso would have known: 118 x 8.6 = 1015 miles not 1278 miles -half of what was thought of the distance to Howland of 2556 Miles as over the original route. Both US and British companies mined for guano until about 1890. The Island of Kirimati, part of the Republic of Kiribati, is one of the few inhabited islands to experience the arrival of the new year before anybody else. The G/S at the 0718 GMT point, full on into the 26 Smph headwind was likely to be 123 Smph, before the climb to altitude. The fuel loads that we know of, and the mileages that they were intended for: a. Oakland to Honolulu: 947 USG for 2400 statute miles which included a 40% excess range, i.e. Did he do that? Say 157 as 1-50-7 over and over and you can get the idea of what Balfour thought he had heard. From the power setting in the Cruise, which in still air will deliver a known speed derived from flight testing, the navigator will know how fast the aircraft should be going in nil wind and when his known position by landmark sightings or his sextant sightings has fixed a position on the Earth, the speed over distance can be ascertained with a degree of certainty. i. The largish (for the time) 4-engined turboprop freighter I was a crew member on as a Flight Engineer, flew at 1.1 times the Speed for Minimum Drag expressed as 1.1 Vmd. . After she had done a test flight, I topped them up again before her final take-off. Both Howland and Baker are low-lying, nearly flat, sandy coral islands that are surrounded by narrow fringing reefs. Note that this 3156 Statute Miles requirement is less than the range possible on 900 USG of the Johnson telegram mentioned at a., above. 0 48' 30" N. West. Where there is a wind, however, a headwind value is subtracted from this TAS speed, say of 150 Smph, and the resultant speed is a G/S which will be lower than 150 Smph, conversely, a tailwind value will be added to the 150 Smph speed to deliver a resultant G/S greater than 150 Smph. c. Lae to . d. Simple mathematics would tell from the past history of the Groundspeed how far they had gone in 8.6 hours (especially in this hypothesis), because the speed is being regulated to the best L/DSmph. If a tentative course to the south (around this area where the low pressure weather was supposed to be) had been made in bad weather and an angled approach then commenced to get back on track by Nukumanu Atoll had been made, then Mount Balbi at 8,500 feet on Bougainville Island would have to be avoided, possibly while still in bad weather. It has also been referred to as WPA Howland Airport (the WPA contributed about 20 percent of the $12,000 cost). Biggest T The best Lift to Drag Ratio for one particular speed will decrease either side of that one particular speed value, if a lower speed for the weight, or a higher speed for the weight is used. There are no natural fresh water resources. He also visited Howland Island and took samples of the guano. Fish and Wildlife Service as an insular area under the U.S. Department of the Interior and is part of the Pacific Remote Islands Marine National Monument. My consideration, after spending innumerable hours on the very large MS Excel plot of the flight, is that the 0518 GMT PR was very close to a correct time and place, but probably made just after the turnpoint over the PR of Mt. Therefore, for a diversion/alternate airfield in case of not finding Howland Island, Amelia had developed a Contingency Plan, that she had formulated before her first world flight attempt, and now also would be used for the second if necessary. There was just not enough information about weather over the vast South Pacific. With this information, then the biggest time difference between two places on earth is a whole 26 hours.
