• Is it possible for an airship gone missing over 100 years ago to still be flying around?

    Best answer: No. It is basically a balloon filled with Hydrogen gas. As you know balloons filled with Helium gas also float. Helium atom is TWICE the size of a Hydrogen atom...and helium balloons finally get soft and land as the Helium escaped between the molecules that make up the bag. Hydrogen would escape even faster... show more

Hydrogen would escape even faster because it is smaller, so it would have landed somewhere...in 1906.

  • Cheap Ultralight Propellor?

    Is there any place to get (or method to create) a cheap, small aircraft propellor? I understand some skilled craftsmen are able to make their own, and the cheapest propellor I’ve been able to find is Tennessee propellor at $276 plus $80 shipping. Am trying to build a small aircraft from scrap parts, weighing around 550 pounds dry. I’m not by looking for any useless answers about how I’m foolish or whatever; just looking for information about propellors. The propellor I’ve found is 2 blade 54” wooden, and I’ve found a smaller 2 blade adjustable synthetic polymer propellor for around $40 more. If there are no cheaper places to buy a propellor, then any recommendations on which propellor to get? Hopefully will be using a ~100 hp 4 cylinder engine with appropriate gear reduction

  • What would happen if you flew your Cessna from Canada to u.s?

    So I’ve been watching a lot of airplane videos and I wondered “what would happen if you flew your personal airplane from Canada to America and landed without a passport?”

  • How would I find out what the two airplanes were?

    Two airplanes flying over western Oregon but one was right behind the other like they were refueling. Were these commercial? Military? They kinda looked like commercial jets. Too far up to tell. How can I find out ?

    Best answer: during WW2 the Germans used a Porridge Like solution

    The most important innovation was Reimar Horten’s idea to coat it in a mix of charcoal dust and wood glue.
    This was the same method eventually used by the U.S. in its first stealth aircraft in the early 1980s, the F-117A Nighthawk.

    The plane was covered in radar absorbent paint with a high graphite content, which has a similar chemical make-up to charcoal.

    After the war the Americans captured the prototype Ho 2-29s along with the blueprints and used some of their technological advances to aid their own designs.

    But experts always doubted claims that the Horten could actually function as a stealth aircraft.

    On the Vulcan the paint was just called Vulcan top coat Vulcan and Canberra use only

  • If (for whatever reason) all of the countries of the world would make it their national priority to locate the remains of flight MH370?

    Best answer: Malaysia Airlines Flight 370 went missing more than THREE years ago. If it hasn't been found yet, "all the countries of the world" are NOT going to expend the kind of resources that might be required to find the wreck.

If it hasn't been found yet, "all the countries of the world" are NOT going to expend the kind of resources that might be required to find the wreck. More likely that it will NEVER be found (like Amelia Earhart's airplane) or that it will be found by someone who is looking for something else.

  • Why is the Pilot and Copilot in a commercial aircraft required to eat separate meals if they eat while at work ?

    Best answer: The idea is if one gets food poisoning, the other will (hopefully) still be OK. It's a bit of an urban legend. I think pilots eat whatever the hell they want.

    The Underwater Locator Beacon operates at a very high frequency of 37.5 KHz, this is confusing for multiple reasons. 1. This is not in the audible range of the Human Ear, meaning it will require special equipment to even detect it even if a vessel or diver is directly over it. This can prevent many additional resources from assisting in finding the Data Recorders, simply because they may not be able to detect it. 2. The higher a frequency, the higher the transmission loss of range (mostly by attenuation, or transfer into heat). This means VERY short detection ranges so short in deep water the transmission may not be detectable unless directly over top the beacon, and in poor acoustic conditions, not even then. 3. The higher the frequency, the more the sound will be refracted, and in many environments in the ocean, this refraction is towards the Deep Sound Channel axis(which is very deep), or towards the bottom, not many environments have acoustic conditions that refract sound upwards. 4. The source level is only about 160 dB//1 micropascal, this is the equivalent of 99 dB in the air, this is not very loud, especially for a source that has to fight through 1-3 above. 5. Modern Submarine distress beacons are low Frequency, audible to the human ear, are battery operated, very compact overall [compact enough to fit into a medium lunch bag if broken down and have long life spans (hundreds of hours).

    Best answer: Almost everything you need book-wise for training in the USA can be downloaded as PDF files for free from the FAA website. These are the books that ALL commercially available materials are based on:

    Airman's Information Manual (AIM)
    Pilots Handbook of Aeronautical Knowledge
    Airplane Flying Handbook:
    Aviation Weather Services
    Student pilot Guide
    Private Pilot Test Guide
    Aeronautical Chart Users Guide
    Weight and Balance Handbook

    Federal Aviation Regulations (FAR's) are here: https://www.faa.gov/regulations_policies...
    You'll need to learn the General Operating and Flight Rules (14 CFR Part 91) and the Certification of Pilotssections (14 CFR Part 61). https://www.faa.gov/regulations_policies...

    The other things, such as a logbook, sectional chart for your area and a course plotter can be picked up for about $25. The only book you really need to buy is a Private Pilot Written Test guide containing examples and answers for all the possible written test questions givenm on the actual FAA test (Jeppeson, Gleim, Sportys, King etc all make them) for about $18.

  • What are the advantages of turboprops over turbofans?

    Best answer: Turboprops are more efficient at lower altitudes. They excel in shorter flights, while turbofans at high altitude (which takes time/distance to do) are even more efficient.
