Wake turbulence and circuits

[johnm]

in the interests of aviation chatter .....................

 

on a previous thread we have 7! aircraft in the circuit - one had 30! with left, centre and right runways - a twin engine using the centre strip

 

Most understand the theory of wake turbulence, but, if at an airstrip - who of us manages it ? - is staying away from the flight profile / vortex ................ enough ?

 

There are lots of examples where wake turbulence can ruin your day

 

Any anecdotes / reminders that some would like to share ?

Saw this recently, makes you think...

Well presented. Shows what you are up against..Nev

More dangerous in stagnant air I think. The vortex doesn't get blown away or disturbed.

 

Ironically you often feel relaxed and happy in calm air....

 

I felt it once at 2000 when an aircraft travelling with me, over took and passed across my front, again in still air.

 

My left wing suddenly dropped 30 degrees in an instant.

Above and upwind of preceding aircraft is the safest I recall. In stable conditions it may persist for longer.

 

Something to remember is if full aileron doesn't lift the desired wing make sure you have speed and use further effect of rudder. Don't give up the fight without using all you've got.. Nev

The moral of the story: Make sure your plane is bigger than those of your mates....

The other moral if the story is don’t be too impatient taking off after your mate has just lifted off

 

Also allow some serious spacing as it can and will bite you if you provoke the tiger

The transition from low tow in a glider at takeoff to high tow for the climb puts the,glider right in the wake,turbulence and gives a,first,time towee a bit of a,thrill!

 

If the towee messes it,up,a,bit, the thrill extends along the,tow,rope,to,the,tower!

The TUG might get toey too. Nev

A FLYING mag article revives the topic of small wakes with big effect.

You wouldn't know for certain that it was wake turbulence,. You frequently hit your own wake in a steep turn where the G loading is much higher. Landing somewhere with trees down each side i needs special attention also. Be on the alert for weird wind s ALWAYS. Helicopters and Heavies have the worst wake effects.   When a glider is towed it will go through the tug plane's wake when it goes from above to below.  Nev
