A new Nynja in the area

[Moneybox]

I like that indicator for best glide speed, one more thing you don’t have to think about in an emergency. 

[facthunter]

If you have a headwind you Must glide faster if distance over the ground is critical. Best glide speed also depends on your weight and C of G. Nev

Yeah, good idea.  And it's also close to the, so called, DMMS (clean stall X 1.4) if you buy into that idea.  

Dan's DMMS, Defined Minium Manoeuvring Speed 1.4 x clean stall, is in most light single engine aircraft the same indicated airspeed for best glide AND best climb. 3 in one value, must have something to do with aerodynamics that AlL aircraft are subject to.

[facthunter]

It's somewhere near the Minimum Drag figure. Turbulence and control actuation causes More drag. Nev

 Very strange that NO ONE has commented about the Headwind effect.  Knowing about it can Make the difference between getting to the Field or falling short.. In cruise you can save a lot of fuel.   Its BAK really. Nev

Is this an Aircraft Forum? Nev

Yes, it's a Skyranger/Nynja forum which drifted towards airspeed indications after Mike showed us his Nynja's newly decorated ASI.

I think we'd all agree that it's a crucial thing to have in mind whenever the prop starts to stop.  And sure, it is basic BAK (which might, itself, explain the lack of reaction).  In any case EFB map pages now offer instant guidance on the matter.  The OzRunways "Glide Assistant" can display in real time a red line around likely reachable territory. It's based on a whole suite of parameters including current altitude, forecast winds and the glide performance figures for your aircraft.  (entered in your Aircraft Profile) Used in conjunction with the yellow 10NM range ring it gives a quick idea of scale. I reckon it's not a bad idea to keep it on all the time as a reminder to keep an eye out for the most hospitable places within range

It's a great feature; I have it turned on.  I apply the principles of being in head wind for the shortest possible time; by increasing to best speed.

Two things here:

1.

If this is a Skyranger site only this website is a comprehensive one with sections for each Aircraft. In terms of safety, what works for one aircraft does not always apply to others, and in some cases what is safe in one does not apply to others. Apart from that, discussions of aircraft in their category make comments a lot easier to find because they're self-sorted. The same goes for the endless comments on self-builds in the General section of the site. It's usually clear by the questions that the person hasn't been to one of the subsections.

 

2.

Correct me if I'm wrong, but I don't believe Recreational Aviation Australia teaches BAK so facthunter's stunned comments should be a warning to recreational flyers that the principles of flight are there to bite you is you think you can get away without studying the CASA Modules. You get a Certificate for a simpler ability to fly under very specific exemptions, but flying safely in CASA or Airservices air space is not one of the.  CASA has just mentioned his concern about Head Winds. My concern is about Angle of Attack. I know big flying schools with hundreds of students and 20 or so different makes and models of aircraft, sometimes print notes on the aircraft with "speeds" and instruments may also carry the same sort of rough reference, but there are places where having that non-complete information in your head will get you killed in the circuit area or bad weather where you're forced down to lower levels.

From BAK, we know that stalls relate to angle of attack, not speed.

When you are flying straight and level a stall occurs at speed A

When you are making a Rate 1 turn in the circuit, a stall occurs at speed B.

If you miss your circuit turn point and pull your aircraft into a Rate 2 turn a stall occurs at speed C.

In each case your actions have caused a change in the aircraft's angle of attack. In the above intervals, the stick will be further back each time  as the G Forces increase. If you haven't studied and passed the BAK module, I'd recommend doing it before you next fly so you know what the angle of attack is likely to be, and how to ensure the aircraft doesn't exceed the stall angle.

For someone who constantly tells people to research everything you don't follow your own advice.

Saying raaus don't teach bak is very condescending and misinformed.

1. What I said about correctly using the site heading makes it much       faster to do the research.

2. BAK is a specific module. If you want to be constructive, please let us know  where to find the BAK module in within the Recreational Aviation Australia structure.

Have a look it's there .

Everything you mentioned above is covered in theory and practical lessons.

"Skywagon University"  has discovered the BushCat (manufacture now relocated from South Africa to Oz)

 

(Lucky someone in the YT Comments pointed out just what the BushCat owes to the Skyranger!  ;- )

To say that us rpc holders were given a certificate with no bak is going to get reactions .

[facthunter]

The Idea is to discuss and kick around ideas. Is the general Knowledge around what we call BAK adequately understood and applied properly?  I would suggest there is a lot to be desired. People should not be Deterred from asking Questions. It's a good way to learn.  Nev

Based on my experience of this forum, by and large, I'd say yes, it is.  Ignorance of basic aeronautical knowledge is not something that's ever jumped out at me on this site - not even from the keyboards of us amateurs.

Can you point to examples ... say, of the BAK kind?  If nothing else, I reckon we're a mob who's keen to learn and open to all savvy, respectful persuasion.

Where do you see people being deterred from asking questions?  I don't.   Anyway, one lesson we all learned, even before graduating kindergarten is that aggro breeds aggro.  In that regard, in this, our little sand-pit for seniors, I can only suggest there's a lot to be desired.

Turbo stated that rpc holders did not do bak. I corrected him and you get all that out of it.
