Your favorite Compass?

By roger larson

Looking for thoughts on compasses used on trikes.  Seems like i have seen a lot of marine type compasses used?

So what is your favorite type of compass?  

Your favorite Brand?  Model?  Where do i get it.

How do you attach it?

 

Thanks  in advance for anyone that will give me input.

Sport Pilot Checkride and Flight Review book updated to V4

By Paul Hamilton

 

http://www.trikepilot.com/members/profile/273/pictures/25864/2

I just updated my Checkride book and items 1, 2, and 3 might be of interest to trike pilots

The following items was updated from version 3:

 

1. For a Flight Review, a Proficiency Check now counts as a flight review per 61.56(d). Example: Private pilot airplane adds a WSC trike endorsement per 61.325 with a proficiency check. This now counts as a flight review.

 

2. WSC trike spiral recovery added to Emergency Procedures.

 

3. Flight Following communications examples now added to Airport Operations Radio Communications.

 

4. Updates of what to study and what not to study to for the Airplane Flying Handbook new version 8083-3B and Pilots Handbook of Aeronautical Knowledge new version 8083-25B

Lazy Eight maneuver

By Doug Boyle

The Manufacturer's limitations on pitch and bank are +/- 30 degrees and +/- 60 degrees, respectively.  The FAR's also state that a parachute while be donned when exceeding the same limits.  Thus, this discussion will not delve into aerobatic flight which is prohibited by the manufactures of Trikes and further restrained through the FAR's.

With that being said, I'd like to entertain the notion of using the Lazy Eight maneuver in Advanced Trike training.  As a Commercial Pilot program training exercise used in General Aviation, this maneuver can aid the Master Trike pilot in "becoming one" with his/her aircraft.  Furthermore, it can encompass the "new" training requirement of Spiral Dive Recovery in the discussion of avoidance, entry, and exit.  Unusual Attitudes will glove into the discussion and demonstration, as well.

Lazy Eight maneuvers involve maximum pitch and bank attitudes, in intervals, as a 180 degree turn is completed in both directions.  When done correctly they provide the feeling of "dancing with the wind".  From level flight the turn is begun with a progressive bank that maximizes at the 90 degree point and minimizes at the 180 degree point.  Pitch is progressive,as well, and maximizes at the 45 degree point and becomes neutral at the 90 degree point.  At the 135 degeee point the pitch is at its lowest as you're reducing your bank.  At the 180 degree point all is back to normal and we roll and pitch into the opposite direction. 

Begun at cruising rpm and level flight the goal is to return to the original speed and altitude without varying your power.  You learn to trade your airspeed in pitch control while simultaneously banking/unbanking your wing.  During the training the pilot will be exposed to "unusual attitudes" and "uncoordinated flight", until the practice concludes with the knowledge and skillful application of "aviation artistry".

To keep the pilot from getting anxious, begin with normal pitch and banks in the execution/demonstration.  Work up to the limits based upon your student's reaction. If you choose to delve deeper into this precision flight regime, try it with power off (idle) and compare the altitude loss with the completion of each maneuver.  Have fun but ALWAYS afford yourself the proper airspace and altitude to stay safe.  Clearing turns are a MUST!  Let's go fly...."slipping the surly bonds of Earth".

Paraglider dashboard, must have FREE Android cell phone app

By jeff trike

https://play.google.com/store/apps/details?id=com.eb.ohrh.parawind.free&hl=en

I downloaded this app and took it out for a test flight this morning.  It is fantastic.  It was developed by a paraglider pilot, but works great on my trike.  It has all the usual features, like altitude, ground speed, moving map display.  I already had this capability, but the paraglider dashboard does something I have not found in any other apps.  It estimates the wind vector in real time while you are flying from the gps groundspeed measurements alone.

Years ago I had done something simliar for a work application, so I have a guess at how it works.   When you fly in circle with you drift downwind. And if you plot your velocity east, vs velocity north, you get a circle with the radius of the circle equal to your airspeed, and the center of the circle offset from zero  by the east and north component of the wind.  You don't need a full circle, a 90 degree arc has enough data to estimate the wind. And paraglider dashboard does this continually, plotting your recent east and north components in one of its displays. When a decent arc or circle is displayed, you get good wind estimates. New data is plotted with big dots, old data with smaller dots.  If you fly straight for a long time, the estimates degrade, but as long as you have a decent arc or circle in the display, you get a good wind estimate.

It displays the data in metric or english units.   It has a nice variometer display.  It logs your tracks and has a good moving map display.  You could use this as your primary gps navigation device.  It is really well done. 

The unique feature is the wind estimator.  

And the app is FREE with no advertisments.

Defensive Flying

By jeff trike

We have all heard of defensive driving, do small things all the time to reduce risk while driving.   This is a stream of conciousness blog of defensive flying techniques I do to minimize risk while flying my trike.   Please add to the list, 

  1. Engine warm up.   It is good for the engine, and if your engine is having problems, them happen now, while you are on the ground instead of the air.  I do something that is frowned on by some, but I not without some thought.  Before flight, I push my trike to the edge of the ramp, where no casual observer should be able to get to the prop.  Turn on the strobes and start the engine sitting outside my trike.  Then I back away and let it run.  I have a clear view of the engine to check for any problems in the carbs, coolant leak, etc.  I in front of the nose on my trike and put on my flight suit so I can keep an eye on things.  Then I do one last check for any engine leaks.
  2. Run through a short checklist one last time before taxing out.  Visor down?  Helmet strap?  Seatbelt.  I still manage to somehow takeoff with my helmet strap or seatbelt unbuckkled about once a year.   Don't be in a rush.
  3. Always do a touch and go before leaving the pattern.  A large fraction of problems happen in the first 5 - 10 minutes.  If they are gonna happen, let them happen in the pattern.
  4. Slowly accelerate on takeoff.   Don't blast off.  If something is going to shake off, let it happen while your wheels are on the ground.
  5. If something is wrong, land and fix it.  Radio adjustments, camera batteries, etc, etc, etc.  Don't screw around with it while flying if landing is an easy option.
  6. Always do a radio check before takeoff.   Usually someone is in the pattern and will gladly oblige, and you give them a radio check too. 
  7. In nice conditions, all your landings should be power off.  The only time I use gas for a stabilized approach is if it is really gusty or cross wind and I want to be able to work the whole length of runway to land.
  8. Aim for the touchdown spot instead of the numbers.  That way you can land short and you'll realize it.   If you always go for the numbers, you will cheat and use gas to hit them, and you will never realize how bad you are as setting up your final glide.  
  9. Don't assume you have radio contact in the pattern.  Fly predictably in case your push-to-talk is broken, the radio 1/2 switch is set on the wrong radio, your antenna cable is loose or one of the dozen ways your radio will fail.  My radio has a red LED that comes on when it transmits.  Seeing that is a good sign.  If the other pilot in the pattern does not respond, chances are your radio is off, but it could be his too.  Fly predictably, always entered on the downwind leg, use the preferred runway if winds allow, no mid-field takeoffs, announce your position and altitude in the pattern.
  10. Flying low is fun and potentially.  If you are down to 100 ft or less, be wary of powerlines.  Almost all dirt or paved roads have powerlines along side them.  
  11. Always top off your gas tank before leaving the hangar.  It will save you time the next time you fly, and you will always have gas.
  12. Rig up a sight gauge for the gas tank on your trike.  You want to be able to trust it with your life.
  13. Have multiple ways to estimate remaining fuel.  I have four:  1) sight gauge, 2) fuel float sensor, 3) fuel flow accumulator, 4) my watch.  
  14. Fly with a friend.  If something goes wrong, he can call for help quickly and save your life.  Your survival odds just increased by a factor of 10000.
  15. Get a SPOT or Delorme Inreach or something like it.  Your family will be able to see if your spot is moving which means you haven't crashed.
  16. Do push your envelope.  Don't always fly in the first hour of daylight.  Someday you find yourself in less than ideal condtions and you want this to be a minor irritaion, not a life or death beyond you capabilities situation.
  17. Install carb heat on your engine.  I have always on carb heat that uses heater blocks after the venturi on the carburators.
  18. Get a radio that can scan, load up all the 122.xxx CTAF frequencies, and let it scan while you fly.   You will pick up other traffic and stay clear.
  19. Get a transponder.  The best safety equipment you can get for your trike.  I think far better than a BRS.  I had 3 sort of scary potential mid-airs at low altitude before I got a transpoder.  None since in the past 10 years.  

  That's all I have for now, Please add your defensive flying techniques to the list

Trike engine reliability. Are they all equal?

By Paul Hamilton

 

What is most interesting is how history repeats itself. A year or two ago I put out a video of flying over Los Angeles. There were critics who expressed their opinions condemning me for flying over a city where there was no suitable landing area with an engine out.

 


Then a very intelligent pilot with lots of aviation experience said something like “there are thousands of single engine airplanes flying over hundreds of cities EVERY DAY in a similar situation. Why is a trike different?”

Good question. Why is a single engine trike aircraft ideology different than all the airplane GA aircraft flying over big cities? Airplane pilots are not badmouthing each other as they fly around. Why are trike pilots different? What motivates trike pilots to have this fearful ideology of engine failure.

It is simple. Here is why. Trikes initially started out with lawn mower engines and progressed to the two stroke ROTAX engines. In the basic “Risk Analysis Matrix” There was a Probable or Occasional likelihood of engine failure simply from the fact of basic two stroke unreliability. Add to that modifications, primitive designs, bad maintenance, and bad operations. There were expectably plenty of engine failures. Now add the four stroke upgrade on experimental’s and things got remarkably better. Why do you think everyone wants a four stroke? THEY ARE SIMPLY MORE RELIABLE. Now add the factory built S-LSA designs with FAA certified mechanics. The S-LSA are simply at a new level of engine reliability if properly maintained. Now we are at the engine reliability level of the GA certificated aircraft. S-LSA have the reliability of all those thousands of single engine aircraft flying over hundreds of cities EVERY DAY.GA airplanes fly IFR into clouds, over mountains at night, and over the open water.

If we try to compare the two stroke and/or old design/badly maintained to a 912 factory design and maintained S-LSA, these are different animals. Not an intelligent comparison.

Modern S-LSA designs maintained by qualified FAA mechanics get to the risk assessment likelihood of remote or possibly improbable. Just like GA engines.

Today I did a flight review in an Ercoupe that was built in 1946. This just came out of annual and I saw it in the shop. It has old systems. However, I feel this is much more reliable than the early two strokes, but I do not think it is as reliable as my Rotax 912 S-LSA that I personally maintain as a FAA Light Sport Repairman Maintenance to S-LSA standards.

So in summary, trikes have come a long way in safety and reliability. So to classify all trikes in the same engine failure likelihood category does not make sense. This is pretty simple. There are many different levels of reliability.

 

 

 

Has who has had engine failures, what type of engine was it (two stroke/four stroke), and what type of a trike was it E-SLA or S-SLA. I would like to find out the statistics so we can get smarter with this.

How to get all trike pilots trained with spiral recovery

By Paul Hamilton

 

Now that we know the new training/testing standards the question is how to successfully implement it? It is important for everyone to get the proper safety training.

 

There are some CFI, and/or DPE’s who teach and others that do not teach spiral recovery.

 

The DPE’s can teach the instructors and the CFI’s can teach all their pilot base with flight reviews. Pilots simply ask for it.

 

I will provide training (and other CFI’s can do the same) to any DPE if they do not teach it or want some brushup. It is really simple and easy and it can be properly done in less than an hour (unless you are prone to motion sickness)Anything to get this out to all CFI.

 

This will take a little while, 3 years maybe to teach CFI's and get all the trike pilot with their 24 month Flight review.

 

Please provide names so we have a reference.

 

So lets get a list of the CFI’s who teach it and the CFI’s who do not can get the proper training.

 

Please provide CFI and Contact names so we have a reference. This can be from students who received the training of CFI’s who already do it. Also noice to know pilots who are comfortable

What are your wind limitations. Where should they be for different levels of pilots?

By Paul Hamilton

Establishing appropiate wind limitations is an important aspect of ADM/risk analysis.

On the runway, at altitude, in mountains/canyons are the stuations.

 

Where do you draw the line?

These are the four BUMP LEVELS for which I make the GO/NO GO decision to fly:

Nice Air

Moderate bumps

Uncomfortable air

Dangerious

 

What are your bump levels on the runway, at altitude, in mountains/canyons.

New Training and Checkride Spiral Dive Recovery Standards

By Paul Hamilton

Well we finally did it. A great step for triking safety in the future. Thanks to all the discussion and input from Trike Pilots on this important issue. Bacground see: http://www.trikepilot.com/forum/topic/1233

 

 

Just out from the FAA to Designated Pilot Examiners:

 

 

There has been an addition of RECOVERY FROM A SPIRAL DIVE as an Emergency Task in both the Sport Pilot and Private Pilot WSC Practical Test Standards as well as the Weight Shift Control Flying Handbook.  Effective immediately this task must be tested in all practical tests for WSC.

 

 

 

The changes have been made and are now posted on the 630 web page.

 

 

 

Link: http://www.faa.gov/training_testing/testing/test_standards/.  Look for the dates of July, 2017, for the PTS changes.
