08 Basic and Sportsman Narratives

[bubbagates]

I took some time to write up a narrative for both the Basic and Sportsman sequences.

Several folks took some time to correct me a=on a few mistakes and I beleive we now have something reasonable for thse that want it. Personally I use the Aresti and it's important to learn that as you will not have narratives for the unknowns in Sportsman and above.

If anyone feels there are more corrections needed feel free to let me know. In a few days I'll convert both to PDF and put the files here for download

BASIC

Figure 1 – Roll. Just before you get to the center of the box, start an aileron roll. You will not be judged on the rate of the roll – it can be as fast or as slow as you like. Typically, the faster you roll, the harder it is to stop it with the wings level. Give a little down elevator while you are inverted so that you don’t lose altitude, and stop the roll with your wings level. As soon as your wings get level and you complete the roll, your score for this figure is set. However, you will continue to be judged as you fly to the right end of the box so KEEP YOUR WINGS LEVEL and don’t climb or descend. Any deviation on this line will be reflected in downgrades applied to the second maneuver.

Figure 2 - Half Cuban 8. Begin by increasing the throttle to full power and execute a smooth 5/8 inside loop. Again, as you come over the top of this figure, you may need to keep a lot of power as you will be flying into the wind. As you approach the inverted 45 degree line back towards yourself, decrease the power to idle and hold some down elevator to maintain a nice line. Most newcomers make this line too shallow, so concentrate on getting the line correct. After holding the 45 degree line for a bit, execute a half roll to upright and maintain the 45 degree line. Finally, execute a gentle pull to horizontal flight and increase the throttle. You should now be flying back towards the center of the field.

Figure 3 – Hammerhead. Begin this figure by applying full throttle and executing a gentle pull to a vertical upline. Again, use the rudder to keep the plane tracking straight up. Once you have reached sufficient altitude, begin to decrease the power. Leave 3 or 4 clicks of power on, and just before the plane stops moving, apply full rudder. It is almost always easiest to hammer INTO the wind if there is a cross-wind. If the wind is down the runway, hammering either left or right is OK. Once the plane starts to pivot, the throttle can be reduced to idle. One method of preventing the plane from wagging its tail after the pivot is to keep some rudder input after the pivot and slowly take it out as the plane goes down. At the bottom of the line, execute a gentle pull to a horizontal exit and increase the throttle. Try to make the entry radius and exit radius equal don’t execute a sharp pull at the bottom. You should now be flying back to the center of the runway.

Figure 4 - Loop. This figure looks easy and is probably the first aerobatic maneuver you flew when learning to fly. It is, however, extremely difficult to fly well. Begin by increasing the throttle to full power, and start a gentle pull. The size of the loop is not judged, but the bigger the loop, the harder it is to make perfect. Keep the radius consistent and wind correct with rudder if necessary as you execute the first half of the loop. As you come over the top, you may need to keep a fair amount of power as this portion will be flown into the wind. You may even need to apply some down elevator across the top of the loop to keep it round. As the plane starts down the backside of the loop, decrease power smoothly to idle and use the elevator to keep the radius consistent. Finally, increase the power as you come back to horizontal flight. The loop should start and stop in the same place at the same altitude!

Figure 5 - Humpty Bump. As you get to the end of the field, pull a gentle radius to a vertical upline. As you establish this line, use your rudder to keep the plane tracking straight up. Remember that in IMAC, you are judged on the TRACK of the airplane and not its ATTITUDE. So you may have to crab into the wind (with rudder) to maintain a nice vertical line. Once you have gained sufficient altitude, pull a nice gentle radius over the top to a vertical downline and reduce your throttle to idle as you come over the top of the half loop. You should now be looking at the bottom of the airplane as it flies straight down. Be careful as you pull across the top of the half loop to keep the wings level as this will make the downline straighter. Once the airplane has flown down a short ways, complete a half roll. Draw another short line, and then execute a gentle pull back to horizontal flight and bring the throttle back up. For the best score, the lengths of the two lines before and after the half roll should be equal. The airplane should now be headed back towards the center of the field parallel to the runway. As you approach the center of the box, you may notice that the plane has drifted in or out compared to where you started the sequence. You should practice holding the appropriate crab angle through these figures if there

Figure 6 - Reverse Sharks Tooth. Fly a short ways past the center of the field, increase the throttle to full power, and execute a gentle pull to a 45 degree upline. Hold this line for a bit, and then execute a half roll to inverted. You will probably need to hold down elevator to keep this line straight. Use your rudder to keep the plane on track (this will be hard as you will be looking at the back of the plane while it is upside down) and keep the wings level. Once you have executed a short line while inverted, pull a gentle radius over the top of the figure to a vertical downline and reduce throttle to idle. Complete a straight downline and then execute a gentle pull to horizontal, wings level flight and increase the throttle. You should now be headed back towards the center of the field.

Figure 7 - 360 Degree Aerobatic turn. This maneuver will look better when flown centered. Right in front of you roll to somewhere between 60 to 90 degrees and start a 360 degree turn, during the turn, add rudder as needed to maintain altitude and it’s also important to not increase or decrease the bank angle all the way through the maneuver. As the plane is coming around to the end of 360 degrees, start to roll level. The speed of the roll should be the same as when you first rolled to start the maneuver for the best points so timing is important.

Figure 8 - Sharks Tooth. Fly towards the end of the field, and increase power to full throttle. Execute a gentle pull to a vertical upline. As before, use the rudder to maintain a nice vertical track. Execute a gentle pull across the top of the figure to an inverted 45 degree downline coming back towards yourself and decrease the power to idle. Hold down elevator to maintain a nice line (not too shallow!) and then complete a half roll to upright. Hold this line and then execute a gentle pull back to horizontal flight and increase the throttle.

Figure 9 - Vertical line Pull 90 degrees to vertical, fly a short distance and perform a ½ roll, fly the exact same distance as you did before you preformed the ½ roll and push to level.

Figure 10 - One and a half turn positive spin. As you approach the center of the field at a high altitude, begin to reduce the throttle smoothly. As the plane slows, you will have to feed in up elevator to keep it from descending. This will gradually bring the nose up.
Once the throttle has reached idle, keep feeding in up elevator until the nose drops in a stall. You will also have to be keeping the line straight with rudder – particularly if there is any crosswind and your airspeed decreases. Don’t worry if the nose of the plane is cocked 45 degrees before the stall – it is most important to keep the line straight! As the nose drops, feed in rudder in the same direction as the wing that is falling right rudder if the right wing is falling and left rudder if the left wing is falling. Once the spin begins, go to full rudder and full aileron in the same direction (you should already be at full up elevator). After 1.5 turns, neutralize all controls to stop the spin. If the nose is high, give down elevator to establish a vertical downline. After the downline has been established, execute a gentle pull to horizontal flight and increase the throttle.

Sportsman

1.) Bowtie: Just before center, pull up into a 45 degree upline, once the line is established, perform 2 points of a 4 point roll which will place you inverted, continue to climb a short distance and pull to a vertical downline. Fly a short distance straight down and pull to a 45 degree upline, perform a half roll on this line which puts you inverted again and pull to level. You will now be flying to the left side of the field.

2.) Split “S”: You are starting this inverted so just pull a nice round half loop and as soon as you come level perform a half roll to inverted. Be sure not to draw a line before the roll. You are now heading back to the right.

3.) Loop, ½ outside, 1/2 inside: This is best done right in the middle. Start pushing into a nice gentle outside loop just before center, once you get near the top start a one half roll, for the best score, you want to be halfway through the half roll at the very top (IE, knife edge as you go through the top), on the backside of the loop you are now upright so just complete the loop and exit upright. For the best score. stop the loop at the same altitude and point in the sky as when you started the outside portion of the loop and make the radius the same for both sides of the loop, you are still flying to the right.

4.) Hammerhead: Begin this figure by applying full throttle and executing a gentle pull to a vertical upline. Once you have reached sufficient altitude, begin to decrease the power. Leave 3 or 4 clicks of power on, and just before the plane stops moving, apply full rudder. It is almost always easiest to hammer INTO the wind if there is a cross-wind. If the wind is down the runway, hammering either left or right is OK. Once the plane starts to pivot, the throttle can be reduced to idle. One method of preventing the plane from wagging its tail after the pivot is to keep some rudder input after the pivot and slowly take it out as the plane goes down. At the bottom of the line, execute a gentle pull to a horizontal exit and increase the throttle. Try to make the entry radius and exit radius equal don’t execute a sharp pull at the bottom. You should now be flying back to the center of the runway. You are now heading to the left side of the field.

5.) Cross-box Humpty Bump: This figure gives you the option of either bringing the airplane in closer to you or moving it farther out. It will probably present better to the judges if you take this figure out, but if you are finding yourself way out before you start this figure, bring it in. I will describe this figure going OUT. Just prior to the center of the box, increase power to full, and complete a gentle pull to a vertical upline. Insure that this line is vertical before doing any rolling or you will be fighting the line all the way up. Hold the line; execute a ¾ roll to the right. You will now be looking at the top of the airplane. Begin a gentle push for a half outside loop across the top. Reduce power to idle as you pass over the top and check to insure your wings are level to make the downline nice and straight. Complete 2 points of an 8 point roll to the left and hold that line to make the line segments equal in length. Finally, execute a gentle pull to horizontal, level flight while gradually increasing power. You are still flying to the left.

6.) Sharks Tooth: Fly towards the end of the field, and increase power to full throttle. Execute a gentle pull to a vertical upline. As before, use the rudder to maintain a nice vertical track. Execute a half roll in the center of this line. Execute a gentle push across the top of the figure to an upright 45 degree downline coming back towards yourself and decrease the power to idle. Perform one positive snap, I like to blip the throttle during the snap to help keep me online coming out of the snap. Come all the way to idle and finish the 45 degree line, pull to exit upright and horizontal. You are now coming back to the right.

7.) Teardrop: Fly all the way down to the right side, being sure to keep your altitude perfectly level and go to full power and pull to a vertical upline, execute, on the center of this upline, a half roll. Pull a 5/8th loop to a 45 degree downline, perform one full roll on the downline, pull to exit upright and horizontal. You are now heading back to the left.

8.) Vertical Upline: Fly all the way down to the left side, being sure to keep your altitude perfectly level and go to full power then pull to a vertical upline. Execute 2 points of a 4 point roll on the center of this line, push to exit upright and horizontal.You are heading back to the right.

9.) Figure Nine from the Top: As you approach the center of the field at a high altitude, begin to reduce the throttle smoothly. As the plane slows, you will have to feed in up elevator to keep it from descending. This will gradually bring the nose up. Once the throttle has reached idle, keep feeding in up elevator until the nose drops in a stall. You will also have to be keeping the line straight with rudder – particularly if there is any crosswind and your airspeed decreases. Don’t worry if the nose of the plane is cocked 45 degrees before the stall – it is most important to keep the line straight! As the nose drops, feed in rudder in the same direction as the wing that is falling – right rudder if the right wing is falling and left rudder if the left wing is falling. Once the spin begins, go to full rudder and full aileron in the same direction (you should already be at full up elevator). After 1.5 turns, neutralize all controls to stop the spin. If the nose is high, give down elevator to establish a vertical downline. Hold the downline for a moment, and then begin a gentle pull for the 3/4 inside loop. As you pass through the bottom of the loop, smoothly increase power to full and once you reach the horizontal and are inverted, hold that line. You should be giving some down elevator to hold the line. Hold the line for the next maneuver. You are heading to the right.

10.) Inverted 180 Aerobatic turn: You have the option of doing this coming in or going out. This should depend on how much room you have if you want to bring it in. Remember, you have a deadline to consider which for most contests are 100 feet out from where you are. I will assume we are taking it out. From inverted, roll into a 60 to 90 degree banked angle then push to start the turn. Use the rudder and throttle as needed to keep altitude. For the best score, keep the bank angle constant as well as the altitude. When you complete the 180 degree turn, roll out level and inverted. Fly a short straight line while inverted, call yourself out of the box. It’s also important to use the same roll rate to roll out of the maneuver that you used when starting the maneuver.

I am thinking of trying to fly patern. Are there any vidios on line where I can see how the plane looks with someone calling the manuvers?

Just to clarify pattern and IMAC are different animals... similar but different....

Which were you looking to get involved in??

[SleepyC]

UNBELIEVABLE!

Bro you rule.
I was just starting to go over both on the Sim, and had some questions.
I ask a few buddies who help me out, I log on, and BAM you have both of the sequences I was looking at explained.

VERY NICE!
