What are the advantages and disadvantages with helicopters compared to planes?
Helicopters has a limited range compared to planes. Planes need a long pave to operate while helicopters can take off and land a lot more places. Also helicopters can "stand still" in the air while planes need to move all the time.
So depending on what you want to do they have different (dis)advantages.
What are some alternatives to airplanes?
Train (Amtrak), Bus (Greyhound), Car, Boat (for certain locations only)
What is a tactical consideration when planning for Helicopter Landing Zones?
Have a unit form a. 360 degree outer ring with light machine guns. Put a few Lars rocket's in deep cover for backup. Have a few scouts stay behind to warn you of approaching threats
How many gallons of gas does it take to fill a helicopter?
It depends what helicopter it could range from 8 to 80
What is thickness of marking for the helipad area?
Define the perimeter of the TLOF with a continuous 12in line. The marking of the perimeter of a paved FATO would consist of a 12in wide dashed line with 5ft mark and 5ft gap. Define the perimeter of unpaved FATO with 12in thick dashed line consisting of flush-in ground markers, 5ft mark and 5ft gap. The safety area does not need to be marked. The size and thickness of the TDPC markings is dependent upon the size of the helicopter the Helipad is being designed for.
What was the name of the first helicopter and how fast did it fly?
The name of the first helicopter was called kiteoki(meaning an air transport)founded by an African mythologist by the name NKOANA KHUTSO.The first helicopter he created reached an approximate speed of 80 knots per minute.
Can a Chinook airlift another Chinook?
No. It's lifting capacity is about 19,500 lbs, whereas its empty weight (i.e. without fuel or anything else) is 23,400 lbs.
What is the average speed for a helicopter?
For a fairly new helicopter, around 120 knots.
Around 150 mph, except for fast military helicopters.
What is the best helicopter that is remote control?
Syma S107 with Gyro. It doesn't come with a wall charger so you might wanna buy that separately. I got the wall charger for $6.00. The helicopter comes in red, yellow and blue, with prices ranging from about $20.00-$32.00 on amazon.com Make sure it has Gyro because Gyro is basically a stabilizer. Without Gyro your heli will be harder to control and it will fly in a circle a bit.
How old do you have to ride in a helicopter?
It depends on the circumstances.
A rescue helicopter, for instance, would be allowed to take anyone.
The helicopters at an air show may have some restrictions due to insurance etc.
How much does a VH-3D Sea King helicopter cost?
###################IT COSTS $65,214###################### VH-3D Sea King helicopterDescription
Executive transport helicopter.Features
The VH-3D is a twin engine, all-weather helicopter flown by Marine Helicopter Squadron One (HMX-1) and supports the executive transport mission for the President of the United States.Background
The first version of this workhorse helicopter was flown more than 40 years ago and was derived from the Sikorsky S-61 series. Originally developed as an antisubmarine sensor carrier for the U.S. Navy, the Sea King has been replaced in that role by the SH-60F Sea Hawk helicopter as the anti-submarine warfare helicopter. The VH-3D was delivered to HMX-1 in December 1974 as a replacement for the VH-3A, which entered service in 1963. By the end of 1976, the VH-3A had been completely replaced by the VH-3D.Point Of Contact

Is a four bladed helicopter better than a two bladed helicopter?
The concept of "better" does not work into it. Each rotor is designed for a particular purpose, for that particular helicopter. Sometimes the best solution is a two bladed prop. sometimes three, sometimes four, all depending on a wide variety of parameters. It's is analogous to knives. A table knife is designed for certain purposes. A hunting knife is designed for certain purposes.
Both work perfectly for the purposes they were designed for, but they are hardly interchangeable, and one is not "better" than the other.
Can you use a 340cc Yamaha engine for a homemade ultralite helicopter?
If you're looking at sticking a motorbike engine on a helicopter as a project, then it will need a lot of work to make it safe (this assumes its even possible with your engines design). Proper Aviation engines need a dry-sump for their oil feed, and guaranteed positive oil flow, even when inverted, or working on their side as a safety measure.
Try to remember that engines without a positive oil feed seize. A seized engine on a car/motorbike means you come to a grinding halt. A seized engine on a helicopter means you drop like a stone.
What happens when engine fails in helicopter?
if the engine fails a good pilot can 'auto rotate' using the dead rotor to lower the helicopter
