How a passion for airplanes turned into a business

businesswoman, getting more female pilots into the skies is not just her work, it's her passion.

Sibongile Sambo wanted to be a flight attendant with South African Airways, but she did not meet the minimum height requirement to become one.

So she decided to star her own business, and had to sell her car and use her mother's pension money to set it up.

Today, she is the founder of SRS Aviation, Africa's first female aviation company.
SRS Aviation (Pty) Ltd is South Africa’s first, and only, fully empowered, black women-owned and operated airborne services business.

Piloted and pioneered by Sibongile Sambo, SRS Aviation offers clients professional and personalised flight options to destinations around the world, Our Air charter services varies from VIP Charter, Tourist Charter, Cargo Charter; Game Count & Capture and Helicopter Services.

SRS Aviation is the African distributor of new and overhauled aircraft spare parts for the commercial, commuter, corporate, Military and Cargo aerospace Industries

We also provide Ground handling Services Equipment:-
•Leasing / Rent
•Maintenance
•Fleet Management
•Sales

The freedom to fly is considered SRS Aviation’s most treasured prize to its individual clients, business partners; because each staff member understands what freedom truly feels like, the company considers qualified and experienced candidates that can add value to the services and overall business offering.

It’s one thing to give someone an opportunity to learn to fly. It’s quite another to watch them soar on wings into new worlds.

Aviation pioneers Orville and Wilbur Wright had a mission: Fly forward for as long as possible, maintain speed, land at a point at least as high as the takeoff point and carry one pilot. In December 1903, the Wrights did just that, flying 852 feet (260 m) in 59 seconds.
Today, expectations are much higher. For example, as the world’s most advanced family of jetliners, the 787 Dreamliner is designed to carry as many as 290 passengers as far as 8,500 nautical miles (15,750 km) — a third of the way around the Earth.
So it’s no surprise that to meet today’s missions, airplane electrical systems have been transformed from the single electric spark the Wright Brothers needed to the highly engineered, redundant systems that make modern jet travel possible.

A company says a proposed Environmental Control and Life Support System could extract water from rocky material on Mars
The system would convert some of the water to oxygen for astronauts to breathe
But many questions about the system need to be answered, so engineers will need more time to study it, a study's authors say

(CNN)—When the first two human colonists land on Mars, they could step into their ready-made living quarters, remove their space helmets and inhale deliciously breathable air.

The quarters would have an optimal mixture of gases for human respiration, and be perfectly pressurized, air-conditioned and thoroughly filtered, if a design paper by a space life-support company becomes reality.

And that air will have been waiting there for two years for the astronauts to arrive. That much time is needed to make sure the Environmental Control and Life Support System, or ECLSS, has a solid track record of working reliably.

The colonists' lives depend on it. Mars' atmosphere is about 95% carbon dioxide and nearly 0% oxygen, a recipe for rapid death.

Landing gear is the undercarriage of an aircraft or spacecraft and is often referred to as such.

For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land and usually to taxi without damage. Wheels are typically used but skids, skis, floats or a combination of these and other elements can be deployed depending both on the surface and on whether the craft only operates vertically (VTOL) or is able to taxi along the surface. Faster aircraft usually have retractable undercarriage, which folds away during flight to reduce air resistance or drag.

For launch vehicles and spacecraft landers, the landing gear is typically designed to support the vehicle only post-flight, and are not used for takeoff or surface movement.

aileron - the hinged surfaces of the trailing edge of a wing (far from the body of the plane) that move up and down in order to roll the plane from side to side.
cockpit - where the pilots fly the plane, located at the front of the plane.
door - allows people to enter and exit the plane.
fin - the vertical part of the rear of the tail. The rudder is located on the trailing edge of the fin.
fuselage - the body of the airplane (excluding the wing and tail). Passengers and cargo are carried towards the rear of the fuselage.
jet engines - the part of the aircraft that provides the power for the flight.
landing gear - the retractible wheels fastened to the main part of the body (by struts) - it is used for landing and moving the plane around on the ground.
nose - the forward part of the plane.
nosewheel - the part of the landing gear located under the nose of the plane.
rudder - the vertical part of the tail; it can move left/right to stabilize the airplane during takeoffs and landings in strong wind or in crosswinds (it controls yaw).
tail - the rear section of the plane, consisting of horizontal and vertical (fin) components.
windows - sealed viewing portals, located along the sides of the plane.
wing - the airplane's two wings produce lift as the plane moves through the air. The wings have four moveable controls: ailerons, flaps, slats, and spoilers.

The fuselage (/ˈfjuːzəlɑːʒ/; from the French fuselé "spindle-shaped") is an aircraft's main body section that holds crew and passengers or cargo. In single-engine aircraft it will usually contain an engine, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage which in turn is used as a floating hull. The fuselage also serves to position control and stabilization surfaces in specific relationships to lifting surfaces, required for aircraft stability and maneuverability.

A fixed-wing aircraft is an aircraft capable of flight using wings that generate lift caused by the vehicle's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft, in which the wings form a rotor mounted on a spinning shaft, and ornithopters, in which the wings flap in similar manner to a bird.

Glider fixed-wing aircraft, including free-flying gliders of various kinds and tethered kites, can use moving air to gain height. Powered fixed-wing aircraft that gain forward thrust from an engine (aeroplanes) include powered paragliders, powered hang gliders and some ground effect vehicles.

The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang-gliders, variable-sweep wing aircraft and aeroplanes using wing-warping are all fixed-wing aircraft. Most fixed-wing aircraft are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled.

When it comes to building vehicles, cars are relatively easy. So are boats. Heck, you can even make your own model rockets without a hitch (mostly). But putting together a plane requires some real aviation design and expertise.

The MakerPlane is an open-source project that’s looking to change all that—along with the aviation industry. Instead of going through all the aeronautical engineering to make sure your plane will fly right, the flight-experienced minds behind MakerPlane propose building a plane from digital plans that you can fabricate using computer-controlled systems like CNC machines and 3D printers.

MakerPlane

They’re not joking.

They have plans for a 630-pound aircraft with a wingspan of 32.8 feet, all lifting off the ground with an 80- to 130-horsepower engine.

The MakerPlane took 18 months to design, and the team behind it has started to construct the prototypes and parts necessary to test and validate the concept. To build the plane, the team has been cutting out the major parts of the frame out of fiberglass and epoxy materials. MakerPlane uses 3D printers for non-structural components, such as throttle k***s, handles and so on, as well as for tools and jigs to assist with the build process.

But why build it with digital fabrication tools instead of regular ones?

The MakerPlane folks say only about 2000 new aircraft enter the global registry each year, compared to the 6000 projects that start and ultimately fail. One of the major hurdles is the aforementioned need for aeronautical engineering skills to design and build a plane. Even with those skills, building a single wing rib—the supporting piece of the wing that gives its curved shape and rigidity—could take hours to make by hand. A CNC machine could cut one in as few as two to three minutes.
