It depends on the type of engine the ultralight uses, the most common being a petrol powered piston cylinder engine like the one found in most cars and motorcycles so the fuel used would be petrol
The FAA has several restrictions on ultralight class aircraft. One of those is a speed restriction."[ an ultralight vehicle is a vehicle that:] (3) Is not capable of more than 55 knots calibrated airspeed at full power in level flight;"So any aircraft capable of more than 55 knots (about 63mph) in level flight would not fall under the ultralight category and would have to be registered as a homebuilt experimental or recreational aircraft.
The one that came with it. If you're buying a used ultralight with no propeller and the manufacturer is still in business, contact them for a replacement. If they're out of business, do a web search for ultralight aircraft forums, join one and ask the membership what to get.
The cheapest is to build an ultralight aircraft from a kit, or purchase one. You will still require substantial knowledge about the aircraft and flight regulations, but you would not be subject to as many administrative rules and qualifications.
Microlights, or ultralights in some countries, are small, fixed wing one or two seat aircraft. A person may or may not need special permits to fly an ultralight. Each country sets its own regulations. In the US one would check with the FAA for rules and regulations for ultralight (microlight) flying.
From left to right.On a twin engined aircraft, engine one will be on the left wing, engine two on the right. On a four-engined aircraft, engines one and two will be on the left wing, with engine one being the outer engine and engine two being the inner engine. Engine three and four will be on the right wing with engine three being the inner engine and four being the outer.On aircraft which have two engines in-line like the Cessna skymaster. The forward engine is engine one and the aft engine is engine two.
It depends on the size of the aircraft. A smaller airplane like Cessna has only one engine. The biggest cargo plane like Antonov has six engines.
In most modern aircraft the other engines will cope with one out.
improved engine performance.
Ultralight's can be very inexpensive. Roger Mann (Ragwing Aircraft) sells plans for a Aircamper replica that you can scratch build for $2000. Then you can use a half VW, and use regular car gasoline. Plus, it's inexpensive, and you can fix problems yourself instead of having a mechanic fix it.But if you don't want to build one, Barnstormers is a VERY good website for finding cheap ultralights.You need to remember that if your buying an ultralight, to qualify as an ultralight in the United States, it needs to weigh 257 lBs or less, a fuel tank not exceeding five gallons, and a stall speed of 27 MPH or less.
aircraft engines only move one way... no reverse
Only there's no one on the aircraft carrier.
