ZU-DVE (and ZS-WUO) (and ZEE) Flight Log

[Wargames]

Gert when you say lost power, was it a reduction in rpm as if suffering fuel starvation, or a sudden off. The first would be as a result of a fuel related issue, the second an electrical one.

This is it - was it a reduction in rpm as if suffering fuel starvation.

[Morph]

Cool so check the whole fuel system then. It's weird that while climbing it starved and as soon as he put the nose down it came back to full power twice. I would also check the pickup in the tank, maybe there is some gunge on the bottom that is moving around and blocked the pickup

Over 5 hours flying with WUO this weekend - see http://www.zu-dve.com

As for the DVE incident, full refs going up, then a moment of loss of power, getting a change in the whining sound of that 582 and a sudden loss of thrust (= rpm going down). In that moment I pulled in the wing, so I cannot say that that rectified the problem, maybe if I kept the wing out the same would have happened.

Morph, I have dual outflow from the tank, chances of gunge blocking both sides' pickup small.

The real lesson here for me (since I am an engin agnostic) is to have a plan when taking off from Morningstar. Taking off on 20 leaves gumtrees as a landing spot, on 02 the ostrich farm is OK. With a trike, climbing maximum, there is only a brief period where you will not make it over the gumtrees at either end (20 being the worst). So I figure one should veer to the N7 side immediately giving you the option of making a u-turn and ending up on the grass to the side of the runway.

What would the guys with fixed wings and those needing more of the runway than a trike will do with an engin out on takeoff?

Both Francois and Dirk's only regrets on my sucessfull landings was that they did not see me use the ballistic chute.

Cut down the Gumtrees.

Food for thought. Most guys doing a "u turn" don't make the runway or next to it because they don't have the height when the EFATO takes place . The training says 45 deg on either side of the direction of the runway. Remember a "u turn" is not a 180 deg turn but takes you through a full 360 deg.

[Wargames]

The training says 45 deg on either side of the direction of the runway.

That takes you either onto the N7, which is pretty busy, or into the trees. Neither a spot I want to land in.

Remember a "u turn" is not a 180 deg turn but takes you through a full 360 deg.

It will only be a 180deg turn. The aim is not to land upwind again, but merely not to land in the trees. I am normally about 300ft over threshold on take off. That is not enough to go over the trees, but surely enough to do a teardrop and land downwind.

I am with gert on this one that the safest takeoff is a veer over the N7, which will make for an easier recovery.

[AndyG]

Not familiar with your airfield so you guys know best. Whether it is a teardrop or u turn it still takes you through 360 deg. Work it out. The same argument was on Avcom about 18 months ago. You cannot pivot 180 deg on your axis to set you back in line for the runway. There are 4 turns involved and each one takes you through 90 deg.

I think in this case of an engine out or splutter on take off the 'teardrop' turn would be 180 degree to have him land DOWNWIND.

[AndyG]

Still takes you through 360 deg. And you will be downwind.

[Wargames]

Andy is correct with the 360. You would basically have to do a 270 and another 90. That is where the idea came from to deviate over the N7 at about 100ft. And then fly over the N7 until clear of obstacles. In this way, if you have an "event", you can just do a 180 do be back on the runway, because you have already done 180.

[Grumpy]

No, I dont agree, If you have just taken off and are still in the straight line of the runway, and you do a 180 you will be downwind to the runway and be able to land on the grass.

[AndyG]

Grumps you are correct if you are going to land parrallel to the runway. My statements above were if you did a u turn back to the runway you took off from. My apologies if I misinterpreted it. However lots of people will still say you have only done 180deg if you turn back to the runway of departure when in fact you have passed through 360 deg.

Owe you a beer when I come down on 8th April.

[gertcoetzee]

to the reciprocal runway heading.

U turn here means changing your heading in the opposite direction. Strictly speaking you will be off track - in our case ending up next to the runway, which would cause considerably less bruises than ending up in the gumtrees.

If you want to get back on the runway you will roughly need to make a right turn right, another right turn, another right turn, and then a left to get back on the runway = 4 X 90 degrees. In my case i want to make a right turn, another right turn = 2 X 90 degrees, and end up next to the runway.

Strictly speaking, if I was veering say 25 degrees to the left to start off with, in order to end up facing the opposite direction I have to correct for that as well, making my turn 200 degrees to end up on the grass.

The point here, and this is specifically for Morningstar is that, if there is not enough runway to land, 45 degrees to the sides is not practical until a point where you have enough altitude to get over the gumtrees. Up to that point turning back for the grass is best.

Sorry for hijacking your log Gert. As I said above I will be in CPT in a few weeks and would really like to meet some of you guys.(even Grumpy )

Trust me you don't want to meet grumps! You will be scarred for life!
