Chandelles and lazy eights...Have Q's

[bobbysamd]

Lazy 8 power

in a lazy eight, is the power left alone in the setting the allows for Va after trim, or is it adjusted throughout the maneuver?

Keep your hand off the throttle. Take a look at the PTS and/or Flight Training Handbook if you have any doubts.

[B The thing is, is that during this section of the maneuver you will also be taking out the 30 degrees of bank which will mean the vertical component of lift will increse [/B]

that's it, now it makes a lot more sense, thanks

Steps for chandelles:

2. simultaneously add full power and roll into 30 degree bank without pitching up.

Lazy 8's

The way I learned to do these well is to SLOWLY roll about 5 degrees of bank and SLOWLY pitch up simultaneously. Practice that several times before you attempt the full maneuver. Once you have that down, do the above mentioned again, only this time hold the yoke in the same position as far as bank goes and SLOWLY increase pitch until your feet and legs are parallel with the horizon. As you increase pitch, your bank angle will increase also to about 30 degrees. Hold that picture! At the appropriate speed, the airplane will cut through just like it's supposed to. It's important to stay coordinated throughout the entire maneuver! As the aircraft "breaks" and starts heading toward Earth, SLOWLY pull back on the yoke until you are again at level flight. Repeat to the right.

I've done these in both high and low wing aircraft and have had the same sucess.

To perfect this maneuver, you may want to consider covering your instruments with a sectional or towel to help keep your head outside the airplane. It's cool too to uncover the instruments at the end of the maneuver and see the altimeter show exactly the same as you entered it!

Once you have this down, you will want to do this maneuver everytime you fly. When you teach someone else to do this, it is one of the most satisfying moments you can have with your clothes on (for the record though, I've never tried them without clothes)!! Especially if they too have been struggling with this!

Hope this helps! Keep us posted!

I finally realized the value of using landmarks as references. It helps tremendously, and lazy eights are really not that hard.
I still keep rocking pretty hard just before stall in a chandelle, had to cut the power and jam the right pedal in to keep it from spinning.

Any gouge on eights-on-pylons, other than dive when slow, pull up when fast?

ceo,


If you're stalling before the end of the chandelle you're probably doing one of two things wrong; either pitching up before completing your 30 degree bank (should be at the 45 degree point), or pitching up too much. I've seen some posters saying 14-15 degrees pitch up. Depends on the airplane. I like 12 degrees in the Arrow. Puts the stall warning light on at the end every time. And I don't ever release back pressure. Just use the AI for reference to 12 degrees pitch up (but don't fixate!!!!).

Try the lazy eights a few times with the AI covered. Once students see they can do it w/o anything other than visual reference it seems to really make the maneuver easier.

8's on pylons...

If you are in a Cessna, use the rivot line on the underside of the wing to put on your "pylon". You will be able to recognize over or under correcting faster than just using the wing as a whole. If the pylon is moving forward in reference to the rivot line, push forward. If the pylon is moving backward, pull back. Also, entering at the pivotal altitude and downwind is extremely important. I made up a small card and kept it in my kneeboard of what the pivotal altitude would be based on groundspeed. Start with 80 to 85 kts. and go up to 100 to 105. The fed who examined me said he didn't have a problem with this. Get your wind info from the nearest reporting station, which may not necessarily be your departure airport.

Sleeping eights

THe only thing I can add to what has been said is to relax a nd quit trying too hard, just let it flow together. Don't think about doing the maneuver, just do it. Maybe do a few lazy eights without trying t o keep things in the PTS - just loosen up a little - get the feel -- then look for the numbers. Talking through the maneuver can help too. For the lazy eights -- keep it outside - dont fixate or try to do the manuver by instruments. just make an eight on the horizon!

various 8s

With 8's on, make sure you anticipate what is going to happen.
If you are descending to your point, because it is in front of you, start leveling off before you get there, otherwise you will shoot right past it.

Same thing when the point is behind. start leveling off before you get there so by the time you are at the point, you will not go past it.

With LAzy 8's I've found that slower is better on the top of the arc. When you are slow with 30 degrees of bank, it is a lot easier to make it around the turn than when you are fast.
