Rv-6 and Rv-6 in inverted flight

Rv-6

Want to do my conversion onto an Rv-6! its a small little 180 horsepower piston engine aircraft that is perfect for aerobatic manoevres, I want to do my conversion and then save up some money to go learn how to do some really insane moves in the air that would make most people bring up their breakfast.

The Spin

When the aircraft enters a spin it is in a stalled flight condition where the aircraft follows a vertical spiralling descent path. The aircraft is stalled but at the same time rolling and yawing and one wing generating more lift than the other. The aircraft is autorotating as long as it is kept in the spin, some aircraft are able to fly themselves out of a spin by just letting go of the flight controls.
Entering a spin deliberately is easy: bring the aircraft in the stall and introduce a yawing motion by applying rudder, left or right. The wing will drop and the aircraft enters a spin and moves about all three axes: rolling, yawing, pitching and uncoordinated thereby losing altitude at low airspeed.

When fully set in a spin, the aircraft spirals downwards at a high rate of descend about the vertical axes and with the wings at a large angle of attack. Some upward force is generated opposite to the weight of the aircraft, slowing its descent. The outer rapidly moving wing has lower AOA and more lift, adding to the rolling motion, contrary to the inner wing with a higher AOA and more drag and this condition helps the aircraft yawing.

Autorotation

This is when the spin starts. The aircraft must be at or beyond the point of stall, and with a difference in AOA between the wings the autorotation starts.
Autorotation is fed by roll and yaw. Roll is caused by the outer wing with lower AOA and more lift and the inner wing has less lift with a higher AOA. Yaw is caused by the inner wing generating more drag.

Normal flight

When a wing drops in normal flight the AOA increases and the wing generates more lift so that there is a natural tendency to roll back and the aircraft stabilizes by itself.

Stalled flight

When a wing drops in stalled flight the increase in AOA causes the wing to be more deeply stalled resulting in less lift and the drop will continue. At this point the drag (C_D) will increase leading into a yaw in the direction of the lower wing. This yaw leads to more roll and autorotation has started.
For autorotation to occur we need only one stalled wing.

Characteristics

Every aircraft has its own spin characteristics, but most will go through an early incipient spin where rate of roll and yaw are fluctuating and the pilot may feel some airframe buffeting. If action is taken at this point the recovery will be almost instantly.
After these initial one or two turns into the spin it will become more developed, wings will be deeply stalled and the attitude will be flatter. Recovery will take more time and probably a turn or two.
Different CG positions will have their effect on stall/spin behaviour. A rearward CG will result in a flatter spin and difficulty with recovery. A forward CG makes spin entry a bit more difficult and the nose will be lower during spin. Recovery is much easier. Which emphasizes the fact that no aircraft should be flown with the CG outside of the limits.

Spin recovery

Normally demonstrated by a qualified flight instructor during flight training (during aerobatics or aircraft familiarization). The exact procedure for a full recovery depends on the type of aircraft. But the standard, generalised procedure is as follows:

• Close throttle and flaps up, on some aircraft types flaps may not even be used on spin training
• Apply full opposite rudder to stop the spin rotation
• Hold until rotation stops, this can take a second or a turn or two
• Reduce the AOA by easing the yoke or stick forward
• The moment the spin stops, centralize rudder, level the wings and pull gently out of the dive

Again, the spin is a stalled condition of the aircraft. Unintentional spins can be avoided by not allowing the aircraft to stall (take immediate action to recover) and by avoiding uncoordinated flight which leads to autorotation when flying close to the stalling AOA.

Pc7

We just got invited to sit in the pc7 it was so incredible!! Its a full glass cockpit with every instrument you can imagine. They even have ejection sets and can be fitted to carry weapons, unfortunately we cant go up for a flight because the last person who went up accidentally pulled the ejector seat.

Inside the A380

Airbus A380

The Airbus A380 is a double-deck, wide-body, four-engine jet airliner manufactured by the European corporation Airbus, a subsidiary of EADS. It is the largest passenger airliner in the world. Designed to challenge Boeing's monopoly in the large-aircraft market, the A380 made its maiden flight on 27 April 2005 and entered commercial service in October 2007 with Singapore Airlines. The aircraft was known as the Airbus A3XX during much of its development, before receiving the A380 model number. The nickname Superjumbo has since become associated with it.
The A380's upper deck extends along the entire length of the fuselage, and its width is equivalent to that of a widebody aircraft. This allows for an A380-800's cabin with 5,146 square feet (478.1 m²) of floor space; 49% more floor space than the current next-largest airliner, the Boeing 747-400 with 3,453 square feet (320.8 m²), and provides seating for 525 people in a typical three-class configuration or up to 853 people in all-economy class configurations. The A380-800 has a design range of 15,200 km (8,200 nmi; 9,400 mi), sufficient to fly from New York to Hong Kong for example, and a cruising speed of Mach 0.85 (about 900 km/h or 560 mph at cruising altitude).

Laser incedents

The FAA says there has been another laser incident near Seattle-Tacoma International Airport.
KOMO-TV reports the latest incident involved Continental Flight 1531 that was heading to Chicago Monday night. Officials say a light was shined into the cockpit just after takeoff. The flight continued and landed safely in Chicago.
Officials say these lasers are extremely powerful and can temporarily blind pilots. With incidents on the rise, the FAA has increased the fine for those caught shining lasers into a plane. The fine is now $11,000.
There were 26 incidents at Sea-Tac in 2010 and 1,100 across the country.

Airforce interfering

Its an absolutley spectacular day for flying but until the 31st i cant just get up and go fly when i please. Due to the airforce activity we need to file a flight plan every time we go up, if we dont the pc7`s are going to come flying into us at 600km/h and we dont want that. luckily for my friends and I we can go flying at night when there isnt too much plane activity but we still file to file those freaking flight plans!...

August is coming

Here in margate, August marks the beggining of the windiest month of the year. pilots who have their licences have no trouble flying or landing in heavy winds but a new student may find it a bit rough up there as well as difficult to compensate for cross winds and may just get blown off course. Cross wind landings are tricky procedures in which the plane is touched down on one wheel first so that the wind does not blow you off the runway, even the most experienced pilots can come short with a cross wind landing.

Instrument flying

This is a fun excersise which teaches you to fly in cloud, the instructor puts a special hood on ur head so that you cannot see outside. Once flying under the hood you have to be able to perform the same actions that you would visually except this time with sole reference to your instruments. As if flying without seeing isnt hard enough the instuctor goes further to block out some instruments and simulate engine failure of these instruments and still asks you to do perfect timed turns without seeing or having all of your instruments:)

Simulator

I have 6.9 hours left to do the simulator,just picture staring at a computer screen for a whole hour trying to make a stupid tracking needle go in the direction you want it to. On the brighter side i did a log book summary and saw that i know have a total of 83.1 hours so its going really well and im getting there:)

Aerobatics

The planes from the virginia airshow were here the other day practicing some unbelievable manoevres,and right away i was hooked i decided im going to save up enough money to get my aerobatics rating:D then i can do stalls and flips,loops,rolls and plenty of other stomach turning tricks in the air:)

war games in margate

The pc7s arrived last week and today the gripen fighter,its going to get really busy here at margate airport in the next few days. I flew to port saint johns yesterday to land there for the first time,it was absolutley insane:)
we got out and had lunch on the edge of the cliff with an incredible view,ill post some pics up later for you to see.
