Hi, I've done a bit of research over theyears on Noonan. Mainly biographical, but some navigation. There is actually little known of the instruments carried on the flight. Much more is known of the instruments he used on the Clipper Flights for which he was Chief Navigator. He is quoted in a letter to Weems as always carrying a marine sextant as a 'preventer'. He was an officer in the merchant marine for 22 years. So most information on his navigation for the fateful flight can be supposed only from his MO for the Clipper Flights. Perhaps nore significantly we can surmise more from studying the navigation of Natal to Dakar leg of which I know Gary knows lots! :) Re Greg's question about whether there was a celnav bubble on the Electra. It seems not but there was non refractive glass installed. Regarding the sextant he used . There is a very good photograph of it. It looks to be a Pioneer Octant if I recall correctly? Definitely an octant though and not a quadrant. He also owned a Ludolph sextant at one time. Pan Am used Baush and Lomb octants, so he would be familiar with all of these. Re. Earharts celestail navigation experience. Definitely nil it would seem. Thats why she needed Noonan. At first she was just going to use him for the Pacific stretch but decided to take him all the way. She most definitely would not have done so if it wasnt necessary as she (and Putnam) had far more to gain by her doing the flight SOLO. Someone once questioned her lack of experience and she replied tartly, 'Thats what I have a navigator for!'. Regarding RDF. No she had scant knowledge of this either and in her original plan she intended to take Harry Manning as the radio operator. Noonan distrusted radio direction finding intensely but would have been competent enough to use it. I'm looking forward to seeing the film if it comes to Scotland. From pics I have seen they have done a very good job with Eccleston in resembling Fred. Kind Regards, Jackie Ferrari. ----- Original Message ----- From: "Greg R."

Well, I'm not Gary, but if I remember what I've read over the years about her final flight I think it was actually a Navy quadrant (I think the reason being it was easier to take sight with from an aircraft window - don't remember if the Electra was fitted with a bubble for celnav or not). > Did Earhart herself know any celestial navigation? Kinda doubt it - if I remember right, she never really mastered the RDF (radio direction finder), which I think was supposed to be used for the final navigation to Howland (which was just a speck of land in the vast Pacific Ocean). Earhart wasn't even all that great of a pilot (I read something somewhere that her piloting skills were only regarded as "average"), she ground-looped during the takeoff roll on the first around-the-world attempts and the Electra had to be sent back to Lockeed at Burbank for repairs. -- GregR --- On Thu, 10/22/09, frankreed@HistoricalAtlas.com wrote: > From: frankreed@HistoricalAtlas.com > Subject: [NavList 10236] Amelia Earhart's aerial navigation > To: NavList@fer3.com > Date: Thursday, October 22, 2009, 4:38 PM > > I thought it might be interesting to get a conversation > going about Amelia Earhart's navigation --really Fred > Noonan's navigation-- on their ill-fated circum-navigation > back in 1937.
