(........Site Map.......)

There are several methods of navigation used by pilots to find their way from place to place on this earth of ours.

...1. Pilotage -- navigation by reference only to landmarks.
...2. Dead reckoning -- navigation by use of predetermined vectors of wind and true airspeed and precalculated heading, groundspeed and estimated time of arrival.
...3. Radio navigation -- navigation by use of radio aids, that is, navigation signals broadcast by radio station on the ground or from satellites.
...4. Celestial navigation -- navigation by measuring angles to heavenly bodies such as sun, moon or stars to determine position on the earth.
...5. Inertial navigation -- navigation by self-contained airborne gyroscopic equipment or electronic computers that provide a continuous display of position.

The most pilots use these various methods of navigation in combination...

 

 

Coordinated Universal Time (UTC)

In order to have a uinversal standard time for reference at any point on the earth, it has been eastablished and is known as Coordinated Universal Time (UTC). UTC is also refered to as Z time. UTC replaces GMT which was the universal accepted standard for the measurement of time until December 1985.

Air traffic control and meteorological facilities in both Canada and the United States operate on UTC, or Z time, not local time. a pilot flying on a long cross country flight would be wise to adjust his personal wrist watch to UTC and refer to it when radioing position reports. Such a precaution will eliminate any change of error in reporting time since it is often most difficult to determine extactly when one zone (which, to add to the confusion, might be on local daylight saving time) end and another begins. To be one hour in error when reporting to an air traffic control unit could have seriours consequences.

Why is UTC used as the acronym for Coordinated Universal Time instead of CUT?
In 1970 the Coordinated Universal Time system was devised by an international advisory group of technical experts within the International Telecommunication Union (ITU). The ITU felt it was best to designate a single abbreviation for use in all languages in order to minimize confusion. Since unanimous agreement could not be achieved on using either the English word order - CUT, or the French word order - TUC, the acronym UTC was chosen as a compromise.

This UTC has been shown with UTC scale on the dail ring of our Heroic Pilot 9025 and Aviatrix 6030 watches for pilots.

 



 

Aviation Joke - "Only one engine left"

A 747 was halfway across the atlantic when the captain got on the loud speaker. "Attention, passengers. We have lost one of our engines, but we can certainly reach London with the three we have left. Unfortunately, we will arrive an hour late as a result."

Shortly thereafter, the passengers hear the captain's voice again, "Guess what, folks. We just lost our third engine, but please be assured we can fly with only one. We will now arrive in London three hours late." At this point, one passenger become furious. "For Pete's sake," he shouted, "If we lose another engine, we'll be up here all night!

 

 


Earliest Helicopter

The first recorded model helicopter was designed by the Chinese. During the 4th century BC, children fixed feathers to the top of small round sticks. As well as this principle, a toy named Bamboo Dragonfly in early Formosa which is consisted of a bamboo propellers and a bamboo round stick per Fig. 1 which look like a dragonfly. As they spun the stick between the palms of their hands the bamboo propellers, angled slightly to catch the breeze, rotated in the manner of a modern propeller, lifting the primitive helicopters into the air.

....... .... Fig.1


The first helicopter patent to be granted by the British Patent Office was awarded to Henry Bright in 1859. Comprising two contra-rotating co-axial two -bladed rotors mounted on a vertical shaft per Fig.2, it was subsequently adopted by numerous 20th- century pioneers.

Uufortunately, this German Zeppelin LZ 129 Hindenburg caught fire see Fig.4 and was utterly destroyed in less than one minute while approaching a mooring mast at Lakehurst Naval Air Station in New Jersey on May 6, 1937, at 18:25 local time. Of the 97 people on board, 13 passengers and 22 crew-members were killed. One member of the ground crew also died, bringing the death toll to 36.


 

 

 

Fastest Aircraft - Hypersonic X (X-43A)

Guinness World Records recognized NASA's X-43A cramjet with a new world speed record for a jet-powered aircraft - Mach 9.6, or nearly 7,000 mph. The X-43A set the new mark and broke its own world record on its third and final flight on Nov. 16, 2004. It is compared with other well known aircrafts such as Concorde at Mach 2.05, F16 Fighting Falcon at Mach 2, Boeing 747 at max Mach 0.92. "Mach Number" was named after the Austrian physicist Ernst Mach. Mach 1 is the speed of sound, which is approximately 760 miles per hour. The revolutionary "scramjet" aircraft then burned its engine for around 11 seconds during the flight over the Pacific Ocean.s

SR-71 Blackbird

The SR-71 Blackbird is the fastest aircraft in the world to take off under its own power. Developed for the USAF as reconnaissance aircraft more than 30 years ago, SR-71s are still the world's fastest and highest-flying production aircraft. The aircraft can fly more than Mach 3 for cruising more than one hour.

 

 

 

 

Lightest Aircraft

The paraglider is the lightest aircraft in the world. It is foot launched which means we don`t need wheels to take off or land. Using state of the art fabrics they combine the security of a parachute with modern wing design to produce an aircraft that is very easy to launch, fly and land. It is totally flexible and the entire aircraft fits in a backpack.

The Paragliders came from a design in the 60s, when engineers were attempting to create an aircraft to recuperate space capsules. Paragliding and hangliding were born from this need to have a steerable parachute. Since then, the difference between these parachutes and paragliders has grown.

Smallest Jet

The BD-5J is a single seat home built kit aircraft that was introduced in the early 1970s by Bede Aircraft.   Few kits were completed due to the company's bankruptcy  in  the mid 1970s due to the failure to  deliver  reliable  engines.

The aircraft  used  a  Microturbo TRS-18  turbojet  engine which was manufactured in France and in the U.S.  under license from Microturbo.   The BD-5J holds the Guinness world record for smallest jet propelled aircraft.

The specification as Primary Fuction: Recretion, Engines/Thrust: 1-326 lbs, Weight Empty: 432 lbs, Max.

Cute Biplane

The Guiness Book of World Records credits the Bumble Bee II as the world's smallest biplane.   Unfortunately  on the day of its first flight, after making several passes at a height of about 400 feet, the aircraft's  engine  quit.   The plane was completely destroyed  in  the  resulting  crash. Starr, the pilot, was seriously injured,  but eventually  fully recovered from his injuries.

Although the Bumble Bee II was lost, the original  Bumble Bee  is  on  display  at  the Pima Air & Space Museum in Tuscon, AZ.

Cute Fighter
The world's smallest jet fighter. The McDonnell XF-85 Goblin was designed to be launched from a bomber, intercept enemy fighters, and return to the bomber using a hook and trapeze.   It would then  fold its wings and be lifted back into the bomb bay.   It had  no landing gear, but could use a steel  skid  under  the  fuse- lage and small  runners  on its  wing  tips  for  emergency landings. 

Test pilots reported the XF-85 as stable,  easy to fly,  and able to recover well from spins.   However they found  that due to turbulence from the mother ship  it  was  difficult  to hook up to the bomber's trapeze.   The test program  was cancelled with the advent of mid-air refueling. So there only two were built.

Unusual Looking Aircraft

The Vought  XF5U/V-173  was  an  experimental  fighter aircraft designed for carrier use by the  U. S.  Navy  prior to World War Two. 

The unusual configuration of the aircraft was designed to minimize drag, increasing top speed, yet with the  ability to take off and land at very low speeds.  Initial tests of the aircraft were somewhat  promising,  but  the  U. S.  Navy scrapped the project on March 17, 1947.

Jet propelled aircraft were seen  as  the  future  direction that the U. S. Navy wanted to enter at that time.

The world 's smallest Helicopter

The GEN H-4 is one of the latest achievements in helicopter evolution with a rotor diameter of 13 feet 1 inch and an empty weight of 155 lbs., the GEN H-4 helicopter is recognized by the Guinness Book of Records as the world's smallest helicopter.


............. GEN H-4

The GEN H-4 helicopter prototype, looking much as it appears today, was first shown to the public in 1997. Since that time a number of flights have been successfully completed. GEN H-4 helicopter controls are relatively simple. Rotor speed will make the helicopter climb and descend. Moving the control stick will result in the helicopter flying in that direction. The helicopter has four engines. Should one fail, the others are intended to provide sufficient control to land the helicopter safely. Safety concerns have been raised regarding the helicopter's lack of auto rotation, under one hour endurance with five gallon fuel capacity, and lack of quick control responses due to fixed pitched rotor blades. It appears that a total of seven of the helicopters were sold. The last entry on the GEN H-4 website is dated Dec. 4, 2006.

The largest helicopter

The Mil Mi-12 helicopter is bigger than a Boeing 727 airliner which is the largest helicopter ever to fly. It first flew on July 10, 1968.


Mil Mi-12

Two prototype Mil Mi-12 aircraft were built. They never met design specifications and the program was canceled. One aircraft remains on display in Russia. The second is said to be at the Leontjewitsch Mil plant in Lyubertsy-Panki.

The helicopter features two-rotors mounted to a wing on top of the fuselage. This is the only example of such a system ever used by Mil, and rare for any relatively modern helicopter. A tail rotor is not necessary for aircraft control, and thus eliminated in the design.

The helicopter used wings to support its weight while flying. Their unique design made their outboard portions wider than where the wings met the airframe.

The Mil Mi-12 had a fuselage and tail unit similar to a fixed wing transport. It had a flight crew of six. The cargo hold measuring 92 ft. (28.15 m) by 14 1/2 ft. (4.4 m) would be able to handle different loads, including troops or handling crews.

Production commenced in 1965 with its first prototype. In 1969, the helicopter set a number of payload to altitude records.

First Mass Production Aircraft

The Etrich Taube entered production in 1910 and became the first German scout aircraft of World War I to be produced in numbers. The aircraft was used as an escort, in the attack role, as an observation aircraft, and for pilot training.


..............Etrich Taube

The aircraft is also known as the Etrich Rumpler Taube and the Rumpler Taube. It was invented by Igo Etrich and produced by Edmund Rumpler. When Etrich withdrew from the partnership it became known as the Rumpler Taube.

Controls of the Taube were similar to other early aircraft. Rather than ailerons, the trailing edges of the wings had cables attached to them. These were pulled downward to create drag, lowering the wing to make the aircraft turn.  On some Taube aircraft their two diminutive rudders were hinged. They were operated in a similar manner to aircraft of today. The elevator did not have a hinged surface. It was moved in a similar fashion to the wings. This technique is known as “wing warping.”

The wing coverings of the Taube allowed light to pass through them, making the aircraft difficult to see when passing overhead, especially on a bright day. When combined with a relatively quiet engine, and stable flight characteristics, these qualities made the aircraft particularly effective for reconnaissance and observation.

Taube aircraft crews carried a small number of 4 1/2 to 6 1/2 lb. bombs and hand grenades with them on some missions. They were deployed on bombing missions over both England and France. The aircraft also escorted Zeppelins on bombing raids. While not equipped with machine guns, Taube crews often armed themselves with hand guns to use against their enemies.

It wasn't long before other more maneuverable, faster aircraft replaced the Taube over the front lines of the War. However, it continued on for a short time as a trainer of new pilots.

A total of approximately 494 Taube aircraft of all types were produced by a number of factories throughout Germany.

Piaggio P180 Avanti
Piaggio P180 Avanti
Piaggio P180 Avanti

Twin pusher turboprops, a sleek fuselage, forward canard, and a high "T" tail  enable Avanti aircraft to carry up to  nine passangers at 1,600 mile distances at jet-like speed
s.

Due to its pusher prop propulsion, the Avanti does not sound like a typical turboprop. However the location of the propellers behind the passenger cabin keeps the interior noise level to an absolute minimum.

And all of this comfort comes with turboprop economy and efficiency. The Piaggio P180 Avanti is said to have 30 percent better fuel efficiency than a similar size turbojet aircraft.

A special laminar flow wing enables more engine power to go directly into pushing the aircraft forward through the air, rather than fighting drag producing friction.

The fuselage produces lift in conjunction with the main wing, front canards, and horizontal stabilizer located on top of a T-tail. The canards are not movable and therefore do not contribute to the control of the aircraft. The combination of the lifting surfaces makes for an aerodynamically efficient aircraft.

Piero Ferrari helped bring the P180 project to fruition after Avanti Aviation ran short of money. In October of 2005, the 100th aircraft rolled off of the factory assembly line.

A total of over 175 Piaggio P180 Avanti aircraft have been produced to date.

Ticketime - New Boarding Pass

<<< click each to enlarge

A new boarding pass design concept called Ticketime features a fringe electronic paper strip that can be ripped off and wound around the wrist like a watch. The time displayed on the watch will be set to the time zone of the destination zone you’re headed to, and will be set by the airline/train/bus folks at the time you collect your ticket.

The two ends of the strip have magnetic dots that can be used to fasten the “watch” and also serve to power the unit.

You can keep the watch for the duration of the trip. The strips are recyclable and would need be returned back to the transportation provider when you check in for your return trip.
