How to set up your Compeo/6030 for competition flying

I often get questions about programming routes and how I set up my instrument for competition flying, this usually happens at briefing just before takeoff, when I want to get ready to fly and have no time to go through the setup with someone new to the instrument. Sorry I could not help you guys at takeoff, but here’s the guide to use before the next comp.

Hint: It’s a lot better to do this at home before flying, where you get to know the instrument a bit better, than in the stress of setting up and getting ready to fly the first task of the nationals, or worlds…

I do not write about route programming here, I can do that if you find this useful – leave a comment.

General setup

I have software version 3.28 in my Compeo+, if you have an older version you might not get all the fields I have described here. Upgrading the instrument is not difficult, but not for the complete computer novice either. (I can do it for you, after flying)

There are three pages in the instrument, accurately named P1, P2, and P3 in the top middle of the instrument screen.

I have three fields that I keep the same info on all pages; it’s the upper right field that shows distance to active waypoint, and the upper and middle left fields that show Wind speed and groundspeed. These three are the basic information that always changes during the flight, and if you keep them in the same place it’s easier to read the instrument quickly and accurately.

The reason I lay out the fields like that is to have a natural way of scanning the display, like reading a page top left to bottom right; Starting with the Vario/McReady – course arrow – airspeed/height/distance to TP, next line down – ground and wind speed, and then the variable fields.

You change between the screens in flight by pressing right arrow button.

Page 1 – Startgate

The most important thing when you are flying and waiting for the startgate is to be aware what time the start gate is, and how far it is to cross the cylinder so you can time the start perfectly. It’s also the time to get a feel for the thermals and conditions, so it’s a good idea to note the wind direction and strength.

Page 1
Page 1 - Startgate page
Left side fields, from top.

Wnd Spd – Windspeed – Shows a calculated wind speed. This value is calculated from the difference between airspeed and groundspeed, so there is a big margin for error, consider it an estimate.

Gnd Spd – Groundspeed – Shows your groundspeed from the GPS.

Time – The clock from GPS – Shows the time your GPS is logging. If this time is wrong you need to change the UTC offset in the setup menu. (Typically when daylight savings change or you travel to another time zone)
Also note that you will have a countdown timer to the first startgate in the bottom of the screen when you have activated the competition route.

Right side fields, from top

Dist WP – Distance to center of active waypoint – This will show the distance to the center of the startgate cylinder, not very useful for now.

Cyl Arrival – Estimated arrival at cylinder. This shows the estimated time when you will cross the cylinder when you are gliding towards the cylinder. I usually calculate 1 minute per kilometer, which is 60 km/h groundspeed. This field is a “nice to have” as it confirms what you have estimated in your head.

Dist StCyl – Distance to start cylinder. Very important and useful, shows how far you are from the start cylinder edge. Combine with the countdown clock in the bottom of the screen to calculate when you need to start gliding to take an optimal start.

Dist Toff – Distance to takeoff point. Useful if you have to glide back for a restart in Aerotow competitions, otherwise useful for open distance flights.

Page 2 – On course

During the task you want to know how far it is to the next PT, to plan ahead and find the fastest route there. I do not fly with a mapping GPS, (Just look down for an updated map) so I rely on memory and the cross track information to know where I am in relation to the course and next TP. Having updated windstrength and direction is also nice.

Left side fields, from top.

Wnd Spd – Windspeed – Shows a calculated wind speed. This is calculated from the difference between airspeed and groundspeed, so there is a big margin for error, consider it an estimate.

Gnd Spd – Groundspeed – Shows your groundspeed from the GPS.

Dist goal – Remaining distance of the task. Very nice to know if the goal is close to the last TP so you can start the final glide before that last TP. Also nice morale booster/destroyer depending on how your flights are progressing.

Right side fields, from top.

Dist WP – Distance to center of active waypoint – This will show the distance to the center of the next TP. Usually we have 400 meter radius, but sometimes there might be a 1000m or more radius for special cases. See the lower right field for distance to cylinder, but this is still nice if you forgot to set the right radius in the route (Been there, done that), as it will show you when you are close enough.

XT Error – Cross track error. This is very nice when flying crosswind tasks; it shows how many km you are off track. Minus is left of track, no minus is right.

Alt a WP – Altitude above WP. This is a glide estimate, showing how high you will arrive above the next TP if you glide for it now. I use it as a confirmation that I am where I think I am relative to the TP and wind.

Dist Cyl – Distance to Cylinder. Shows the distance to the cylinder of the next TP. Very useful if there are varying cylinder sizes in the task.

Page 3 – Final glide

Having made it here it’s all about the glide, so the setup changes to focus on glide angles.

Page 3 - Goal page
Left side fields, from top.

Wnd Spd – Windspeed – Shows a calculated wind speed. This is calculated from the difference between airspeed and groundspeed, so there is a big margin for error, consider it an estimate.

Gnd Spd – Groundspeed – Shows your groundspeed from the GPS.

L/D gnd – Glide angle over ground. This shows what your glide over ground is in the moment, somewhat useful to get an idea of your glide, but it varies a lot and is not a good indication if you will make it or not. See the L/D Goal for that.

Right side fields, from top.

Dist WP – Distance to center of active waypoint (Goal). Again this is the center of goal TP, very useful if there is a goal line.

L/D Goal – Glide angle to goal. This shows the angle from where you are and to goal. The most useful function on the final glide! If you are on glide, and the number goes down (From 15:1 to 14:1) you are gliding well and should make it in unless conditions change (Or you speed up too much). If the number goes up (From 12:1 to 15:1) you will not make it and need to look for more lift, more tailwind, or a miracle :-)

Alt a goal – Altitude above goal. This shows the estimated altitude you will arrive over goal if you do an optimal speed glide to goal. (Calculated from the polar you have programmed in the instrument) This number takes wind speed and direction into calculation.

Alt a BG – Altitude above best glide. This shows the estimated altitude you will arrive over goal if you do a best glide to goal. (Slow glides keeping the speed at best glide all the way in) This number takes wind speed and direction into calculation.

Remember;

  • All the glide functions require that the goal waypoint has the correct altitude, and your instrument is set to the correct altitude.
  • You will also need a somewhat correct polar to get useful Alt a goal/Alt a BG values (And useful McReady speeds).
  • The instrument glide functions cannot predict sink or lift on glide, only you can do that!

So there you have my setup, there are lots of information fields in the instrument so I am sure other pilots have different opinions on the optimal setup. Comments and questions are welcome!

(Not that I have been using the vario much lately – Here’s the weather outside as I write this)

A great weekend of sailing and flying

I was at the Moyes factory last Friday to drop off a harness I brought back from Dalby. While I was there there Warren offered to take us sailing with his catamaran on Saturday to go out and meet the 16 year old Jessica Watson girl who sailed solo and unassisted around the world, and on Sunday we could go to Bill’s place at Rylestone and go flying. Great plan!

On Saturday morning Georgia and I met Warren at the Sydney fishmarket and we sailed out the harbor and across to Manly to pick up some more crew. Georgia had to get back on land at Manly as she got seasick in the rough seas. The conditions got even worse when we went out from Manly and got outside the Sydney harbor heads. We broke a rope holding the boom for the spinnaker, and it was a bit of a struggle to get the sail down before it broke. In the 3-4 meter rough waves even I got seasick for the first time in my life, while working to save and secure the spinnaker. I’ve been on boats since I was a kid, and never got close to seasick, fortunately it got better once we got back inside shelter of the south head and into the harbor.

On Sunday morning Warren and I drove up to Rylestone to meet up with Bill Moyes and Steve the tugpilot, to get some towing and flying. Conditions were gray when we drove up, but got nicer during the morning and the first thermals started working just as I was ready to go. Steve gave me a great tow up to 800 meters AGL, and found some weak stuff to hang around in while conditions were improving. Once established in cloudbase at 1900 meters it was a great day.

It was cold though, I was wearing 3 layers of wool and fleece under my Skyline jacket, and still I was shaking of cold for the last half hour of the flight.

I saw 10 eagles during my hour and 20 minutes flight, always in pairs. They seemed to be accepting us flying in their territory and did not attack or seem to be aggressive, very unlike Forbes in January where they were acting like mean bastards!

This eagle in the photo above wanted to play chicken with me, flying straight at me to see who would turn away first. I got it on video, the camera was fogging up a bit by then due to the cold and moist air in cloudbase. It’s still quite cool to see on the film, and seeing all those eagles really made my day! I won the chicken contest since the eagle flapped his wings and rolled away to avoid colliding.

Here’s the video, the eagle passing me is at the end.

It gets dark quickly now, at 16:30 it’s getting too dark to land, and 17:30 is pitch black. After landing and packing up we went to the pub for a few beers and food, it took a while to get the food so we had to get even more beers that what I really needed. We slept on the floor in the “terminal”, with Bill waking up every few hours and putting more wood in the stove to keep it warm inside. I’m still glad I had a “winter” sleeping bag.

The next day it was gray from the morning, and I jumped in the backseat of the tug to give Warren a few lessons, working on his landings. We spend some hours doing landings, stopping now and then to get inside and heat up in front of the fire. I did not bring my winter flying gear from home, and was wearing every piece of fleece I have here :-)

17 May and rain, nothing new. At least we could fly!
17. May and rain, nothing new there. At least we could fly!

Eventually Warren got in a few good landings without bouncing too much and I sent him off on his first solo. He did well, no parts fell off and nothing bent! The rain came around midday so I packed up and drove back to Sydney.

I will go back to Forbes next weekend if the weather is good, hope to get a few more hours of flying there before it’s time to pack up the glider and ship it home.
