The ETA at Howland from what is known, becomes 1672 divided by 124 = 13.48 hours or 13 hours and 29 minutes, therefore, without an increase in speed, Howland will be seen at 13.48 hours + 7.3 hours = 20.78 hours or 2047 GMT. Due to my extended workings of this flight, I do believe that even if the Electra did go to 12,000 feet, it did not stay there for long as basically it is above the normal oxygen required level and the Electra, as far as we know, did not carry oxygen. If the speed is Groundspeed (G/S) in Smph and if the headwind affecting the Electra at 0418 GMT is thought to be 12 Smph as per the low-end forecast, the TAS would be 152 Smph. The higher 100 Octane rated fuel used for take-off had more anti-knock or pre-detonation value than the other fuel available at 87 Octane. She would turn back for the Gilberts to find a cleared area to land the Electra, a beach on which to land, or she would ditch the Electra close to shore. A TikTok user . Generally, at the companies, the BI analyst has to be comfortable in data analysis, SQL, creating models, and data visualizations. This 1936 NatGeo map of the Pacific Ocean cannot be used for navigation to the Phoenix Islands. The MS Excel plot at 0418 GMT, gives a height of 7000 feet, a headwind of 12 mph, a groundspeed of 130 Smph, a TAS of 142 mph which if given an outside air temperature of 14oC would mean an IAS of 122 Smph. There is a mention that Earhart did fly the Electra at 12,000 feet in the U.S. but no mention by Lockheed of any plan to fly the Electra at that height on the Long Range flights. How was that determined ? Note: Clear to half probably intended to mean to Clear to half way Clouds of CIST and ALST means Cirrostratus (High Level Cloud) and Altostratus (Medium Level Cloud) respectively. The distance is 4307 Statute Miles and the time given for the flight is 28 hours and 40 minutes. Availableat the propeller was initially 80% of 888 = 710H.P. [33][34] By 2000, the beacon was reported to be crumbling and it had not been repainted in decades. Colonization projects on the other four islands, also disrupted by the war, were also abandoned. If a pilot as an operator of a particular aircraft studies the L/D Ratio and tabulates the best L/D speed to fly for a given AUW, then the least fuel will be used because the aircraft will be flying with the least aerodynamic drag. As always you can unsubscribe at any time. It applies to the take-off from Oakland on the flight to Hawaii, March 1937, where she writes: Once aloft, I throttled down. Fine weather, but with winds above 7500 feet of over 24 statute miles per hour. The perimeter road hump just off the end of the runway, was said to be the source of the cloud of dust that appeared as the Electra wheels ran over the hump on the dirt road and the Electra leapt into the air. If Fred Noonan had this chart, then he would know how wide the Atoll ring was and could work his groundspeed from that known distance. Speed must be reduced to maintain the Best Lift/S Drag speed. It means the island of Big Diomede is almost a day ahead of its neighbour Little Diomede despite sitting side by side in the Bering Strait between mainland Alaska and Siberia. The remaining threeJarvis Island, Kingman Reef (which is largely submerged), and Palmyra Atollare territories of the United States grouped with the United States Minor Outlying Islands. Or by navigating to the user icon in the top right. Guano Islands Act of 1856. All these clouds moving in from the east, where the winds from 2000 feet to 7500 feet are recorded as from 14 Smph to 24 Smph easterly. 4. I have worked next to a few radio technicians over the years and all have said, You cannot tell the range of an HF Broadcasting Station by the strength or strength number applied. Airline Companies are certified by the National Authorities and airline staff complete all details of Flight Planning. Services are operated by Fiji Airways. Even allowing for this knowledge by Noonan of where the Ontario actually was, the average G/S has not increased. There is widespread community transmission globally. Groundspeed (G/S) = True Airspeed (TAS) plus or minus the Wind Value . The terrain is low-lying and sandy: a coral island surrounded by a narrow fringing reef with a slightly raised central area. The average G/S of 127.5 Smph Choiseul to Nukumanu remained the same at 127 Smph since leaving Nukumanu and the G/S overhead the USS Ontario is 127 Smph and the wind value seems to have decreased at the higher altitude(26 Smph down to 23 Smph) and the headwind component to Noonan is 23 Smph. Time and Date AS 19952023. A Long Range Plan must be strictly followed, The flight is over a widely spaced time difference and crosses the International Date Line, A competent Pilot and a Navigator experienced in Astro Navigation, steering by the stars. DST. There are no permanent inhabitants on the atoll, which is home to several species of migratory seabirds and shorebirds as well as threatened and endangered sea turtles. Have you a Vat 69? I did happen to have one so the three of us knocked it off. It lies in the southwestern Pacific Ocean, about 1,650 miles (2,650 km) southwest of Honolulu. Contents 1: The 100 octane was held in a 97 US Gallon (USG) tank in the left hand wing and by a valve arrangement in the cockpit could be selected to supply both engines. July 28, 1985. Official Coronavirus (COVID-19) Information for Kiribati, The beginners guide to the 2018 World Nomad Games, 4 of the smartest ways to explore Australia, How to get from Heathrow Airport into central London. Howland Island is an uninhabited coral island located just north of the equator in the central Pacific Ocean, about 3,100 km southwest of Honolulu. Of all the tragic radio calls made in the history of aviation, this call has to be the outstandingly most tragic of all. Nikumaroro Island, Phoenix Island Protected Area, Kiribati An expedition bringing bone-sniffing dogs to search for traces of Amelia Earhart has arrived on . Probable G/S at the PR of 132 Smph. It also represents the hypothesiswithin this working MS Excel,that by flying at a lower airspeed than the Lockheed and P&W settings stipulated, Earhart would save precious fuel to enable the surety of reaching Howland Island, and if that was not possible, then the success of The Contingency Plan. Earhart and possibly Noonan, definitely had the intent, that if they could not find Howland, then a return back along the reciprocal course would be entirely possible, certainly to the Gilberts. This was because the navigator had to work out where he had been at the time of the Astro sighting using Almanac tables and mathematics. Airstrips constructed to accommodate her planned stopover were subsequently damaged, not maintained and gradually disappeared. Put a free analog web clock for UM HOW. The mass of the Gilbert Islands are 600 statute miles away from Howland Island and to reach them in nil wind at Cruise Power, Earhart would need 4 Hours of fuel at altitude. Now, if the G/S at the 0518 GMT PR was 131 Smph, it (the G/S) has remained the same after nearly two hours, when in fact due to fuel burn it should have increased by around 2 mph. See more on Cruise Power in, Horsepower (HP) or Brake Horse Power (BHP), The total H.P. All in all, these radio receptions from Earhart did not bode well for the navigation of the flight. 1. Currently, we are unable to provide international travel restriction information for United States Minor Outlying Islands relating to Coronavirus (COVID-19). I have amended the errors in this table below and have also included the Lift/Drag Ratio figures for different speeds and the three weights of the table. Copyright 1998 - 2023 WorldTimeServer.com All rights reserved. Howland Island (/halnd/) is an uninhabited coral island located just north of the equator in the central Pacific Ocean, about 1,700 nautical miles (3,100 km) southwest of Honolulu. In that five minutes (past Nukumanu Island) they would travel about ten miles, so at 0718 GMT, they had completed (224 + 21 + 10 ) 255 Sm in 2 hours giving an average G/S of 127.5 Smph, almost the same speed as the sector Lae-Choiseul. The propellers are in Fine (or low) pitch and the Electra is slowly accelerating after take-off. Fred Noonan was with me at the fueling and checked it out. It featured performances by native Kiribati entertainers and was attended by Kiribati's President Tito. In the 19th century, whaling ships were regular visitors to the islands. What would be the implications of this arrival at the Ontario if Noonan accepted that the Ontario was On Station at 1036 GMT and he had pre-computed the distance and to him, his average G/S was actually 119 Smph with a probable G/S overhead the ship of only 112 Smph because of an increasing wind? For Earhart and Noonan, operating at Lae must have seemed like the end of the Earth; with bad communications between centres having a role to play in the flight and weather forecasting being a mixture of magic, guesswork and voodoo. The Lockheed Cruise Power setting were and are too high for the flight They are the proverbial round peg in a square hole. We have a check on the average speeds times because of the all important 1030 GMT call of Ship in sight ahead which could only have been the USS Ontariomeaning that the Ontario was ahead and visible and if it took a further 6 minutes to be overhead, wethen know that they were half-way (or just over halfway with the USS Ontario being off-station) and on the original FP, had a further 1278 miles to go to Howland at 1036 GMT (after 10.6 Hours). -176.6173 or 176 37' 2" west. Therefore, if an aircraft captain asked: Where are we NAV? The answer would be, Well Captain, at 0900 we were at X and on my plot we should now be at Y and in 15 minutes time we should be at Z, Ill update you after the next fix. Thank you NAV. The NAV update after the next fix would then include points of accuracy and a possible correction of the steer and an interpretation of what the wind was doing, i.e., any changes in speed or direction. Gamble was president of the Vacuum Oil Co., a subsidiary of U.S. Standard Vacuum, when he was a young man. Gilbert and Ellice Islands Colony. Howland Island Tide Times. What caused that difference? The Climb power in the Lockheed Plan was 888 H.P. 176 38' 35" W. East. Then after stabilising and cleaning up the landing gear (and everyone has calmed down), the Electra has to climb. The possibility is that they ran into bad weather, 10/10th cloud up to 30,000 feet at the equator, which negated Freds ability of Astro-navigation; he would have relied on DR navigation where wind can put you 50 miles off course, cloud base too low to get below it because the altimeter is all to hell if you do not know the barometric pressure, and to see a searchlight provided by a U.S. Cruiser under those circumstances would be impossible. Forecast Wind: Nukumanu to Ontario 12-15 mph easterly, then from Ontario to longitude 175, E.N.E at 18 mph (a near direct headwind), resulting in a forecastheadwind component for the Electra of 17 Smph. We need to know what our minimum flying speed (VMIN) is, before we take-off from Lae because we are in the overweight condition and we need to maintain a speed well above VMINand at least 1.3 times VMINto maintain a 30% safety factor as a minimum. The objective of the MS Excel plot is to test the hypothesis that the Electra had gone out into the South Pacific and could return to East New Britain with the available fuel on board. Exact time now, time zone, time difference, sunrise/sunset time and key facts for Line Islands Time (LINT). The two islands are less than five kilometres apart. In modern times a new ETA will be passed forward to the arrival destination as an update or a ground station will relay the new information forward. 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. The International Date Line (IDL) is an internationally accepted demarcation of the surface of Earth, running between the South and North Poles and serving as the boundary between one calendar day and the next. The radio operator at Lae, Harry Balfour must have mis-heard Earharts message. That is simple mathematics. Fish and Wildlife Service and it is generally restricted to scientists and educators. Official Coronavirus (COVID-19) Information for Kiribati. 169 (Rep. Mark Takai) Acknowledging and honoring brave young men from Hawaii who enabled the United States to establish and maintain jurisdiction in remote equatorial islands as prolonged conflict in the Pacific lead to World War II", "Sixteenth Census of the United States: Population, Volume I, Number of Inhabitants, Hawaii (Table 4)", "Welcome to Howland Island National Wildlife Refuge. The International Date Line passes through the Line Islands. Take Kiribati itself, for example. In this hypothesis, I am going to clearly state that I have been down this track many, many times before and I could never achieve the targets of distance mileage to a destination along the flight, Choiseul, Nukumanu or the Ontario at the time or near the times given by Earhart if I used the power settings laid out for her by Lockheed as shown in the previous table at the beginning of this part. Earhart climbed the Electra to a new cruising altitude after Nukumanu. No landings were attempted but both Pellegreno and Finch flew low enough to drop a wreath on the island. Some travel restrictions may still be in place within Kiribati. At 1415 GMT, my plot shows the Electra to be 866 Sm from Howland Island and from then on, over that 866 miles, without Astro Navigation, a ten percent lateral error of 86 miles is possible in theory. This is nonsense. Howland Island was uninhabited when the United States took possession of it in 1857 through claims under the Guano Islands Act of 1856. Forecast wind: Still a headwind, 12-15 Smph from the east. 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. Such a target would be hard to miss and the Gilberts Islands are the best bet if an aircraft is lost because turning back and heading for a large target like the line of the islands in the Gilbert Islands chain is better than heading off at a stab in the dark (so to speak) of a single island or a group of islands widely separated by sea gapswhich could be missed. Find all the transport options for your trip from Howland Island to Line Islands right here. 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. Compounding the communications were the U.S. All we know is that a faint scratchy radio message was heard at 1415 GMT and picked up and recorded by Chief Radio Operator Bellarts on the USCG Itasca. Hence, this region is characteristic of a lake bottom; flat and mostly featureless. If it is 140 Knots IAS then at 161 Smph it definitely does not comply with the ELRP.. They have a land area of 193 square miles (500 square km) and are divided into Northern, Central, and Southern groups. The answer would be the Howland Islands and the Republic of Kiribati's Line Islands. With all other tanks full, this would result in fuel loads of 1110 USG and 1100 USG, respectively. The time of day is the same as in the U.S. state of Hawaii (UTC-10.00), but the date is one day ahead. Some areas on earth use a time zone of +13 hours UTC or even +14 hours UTC. Thomas Bederman, one of the two survivors, later recounted his experience during the incident in a March 9, 1942 edition of Life. 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 0718 GMT point near Nukumanu to the USS Ontario Climb to Cruise height. This report was of this wind on the July 2nd, morning of their intended arrival at Howland. Rome2rio also offers online bookings for selected operators, making reservations easy and straightforward. Using 100 Octane would allow the full 600 H.P. That would mean by the Law of Averages (for illustration only) that if the start speed was 132 Smph and the sector average G/S was 112 Smph then the end Groundspeed at Nukumanu would only be 92 Smph, which is way too slow It is way too slow because the AUW at Nukumanu is 12900 lbs and the VMIN (Minimum flying speed) is 98 Smph they cannot stay in the air at 90 Smph. They were still on the ground at the end of the strip. Note: Earhart liked to have speeds and distances in Statute Mile(s) format and this is followed in the text. Thishypothesis declares that the Electra has reached the Ontario at 1036 GMT and has 1272 miles to run to Howland. The long range Electra 10E at 14,700 lbs was operating above the normal operating weight of a standard 10E, which had a certified 10,500 lb. There is no serious problem as yet, if the adherence to the Earhart Long Range Plan continues and at the best Noonan has discovered that the USCG Ontario is off station and he now knows that he has 1272 Sm remaining to go to Howland. . Fish and Wildlife Service as part of the Pacific Remote Islands National Wildlife Refuge Complex. MyMS Excel plot shows the continual saving of fuel by the lower power setting which could be used to give this economy.
