How Helicopters Fly The circuit
Why fly a circuit in a helicopter?
Aircraft in flight circuits. They fly a lot and we can understand how this helps to improve the management of the pilot of the aircraft. But most of the helicopters usually do not begin their approaches to a runway. We usually approach directly there, where we land. Why do we need to make circuits? There are some good reasons:
Circuit cover a large part of the flight exercises. For example, float, becomes a place, transitions, climbing, mountaineering straightand the level, just to name a few. Flying a circuit that can tell your teacher or examiner, so fly the helicopter and what are your weaknesses. Fly through the circuits, you can get an understanding of the functioning of the airport and the circuit and develop a situational awareness of other aircraft nearby. When you arrive at an airport for the first time, you know follow the procedure and what to expect from you in the loop. If you fly circuitsImprove your management of aircraft and the accuracy will improve your flight. Each small area you end up with will require to fly a circuit.
How Helicopters Fly Circuit
Get ready for the track. If you want to be landing at an airport for the first time, then you need to do a little research.
What is the layout of the launch and landing strips? What you need radio frequencies? What is the height of the circuit helicopter? What direction is the circuit? What isthe height of the airfield? There are obstacles, you should know about?
All this information can be used in the aeronautical information publication (AIP) (in Ireland) to find. Let's say you've done all this, and you fly to the left at the local airport circuits.
Upwind Leg
Before the beginning of a transition for the circuit, make sure to complete the clearing again, be careful not to cut in front of another plane or climb into the belly of aAircraft. Building a mental picture of any other aircraft in the area. This includes taxiing aircraft and other aircraft in the circuit. The transition to forward flight. Overcoming flapback and translational lift. Set a steady climb to 60 knots. Check engine temperatures and pressures during ascent.
Crosswind Leg
If there is 500 meters above ground level (AGL) approach, the plane is obviously correct, clear ahead and clear the left. Select a feature on the ground, is 90Degrees on the left side and turn to him. Carry on up the crosswind leg. If it occurs at 1000 feet AGL approach that the aircraft is obviously correct, clear ahead and clear the left. Level the plane at 1,000 feet above the Attitude, Power, Trim method. 70-80 knots is a good speed circuits (depending on the type of helicopter that flies). Select a function, on the ground, 90 degrees on the left side, and turn that direction. Now you are on the downwind leg.
Lee
We recommendnow be in level flight at 1000 feet AGL and 70 to 80 knots. Perform a "Fred" (fuel, radio, engine temperature and pressure, direction and height). If you think yours is abeam of the boat landing, a line projecting from it at 45 degrees. Where this imaginary line crosses your path, this will be your turning point. Make sure you read clear, clear ahead and clear the left. Select a function, on the ground, 90 degrees on the left side, and turn that direction. They have nowturned leg base.
Base leg
Once on the base leg, lower the collective and be sure to have a positive rate of descent using the vertical speed indicator (VSI). The idea is to descend to 500 feet AGL. Do not worry you have not reached the final 500 meters before turning. Have enough time to lose altitude. Make sure you read clear, clear ahead and clear the left. Turn toward the runway threshold. Now they have turned on its last leg.
FinalLeg
FREDA select another. This slows the aircraft up to 60 knots. If it's a strong wind blowing, you increase the speed for the amount of wind speed near you to the threshold otherwise it will take a long time, have to go.
Fly straight and level at 500 feet and 60 knots until you have a good image side (ask your teacher if you are unsure of what is a photo site) have. If the image of the site in the correct position on the windshield, lower the collectiveand be sure to have a positive rate of descent. Use the collective. Be firm with him and make sure that the helicopter in a constant angle follows the approach point.
At about 300 feet, use a little 'back cyclical bring something to the nose and start to reduce speed. The idea is that there is a progressive reduction in speed from that point until you come to a hover in the doorway.
At 200 meters to decide whether in all the beauty and wellness approach. 200 feetCommit height. If everything is not good at this point - and fly to another circuit.
At 100 meters, you can begin to move the image site on the windshield. Keep the helicopter forward, and come to bring the cursor from your point of landing. Anticipating the loss of translational lift, and be willing to compensate, by the collective. As you increase the collective, you must stay in the pedals to compensate for the variation of torque. Reach a steady hover or. Lands
Now you have completed a circuit helicopter. As you already know by now, require much concentration to do well. I always tell my students never let the helicopter take them, when their brains are not even two minutes before. Plan your chopper circuits. Thinking about the future. Anticipate turning points, your off altitude, FREDA checks, radio calls, etc. to strive for perfection in the circuit. You will never reach it, but this will definitely improve your confidenceand precision of helicopter flight.
