The C172 - probably the best default prop in X-Plane 10

(29.92" - 26.10") ∙ 1000 [ft/inHg] = 3820  I think this is the calculation I  was talking of regarding Altitude based on Hpa. Got to look again.

jcomm,

 

 Did you see the formula above I have posted ? about the altitude.

Yep!

 

We use hPa here in Europe, mostly....  But the algorithm is the same : multiply the lapse by the numer of feet or meter per unit lapse...

What do you mean Hpa is only in Europe mostly ? I thought that's all over.

Hmm no , I want your Altitude just based on your hpa. Lets say your QNH is 30.20 what would your altitude be. What if your Altimeter needle is stuck .

How would you determine your MSL altitude using just the baro pressure and a broken altimeter? I'm not sure what your question is. Your math is correct only for standard atmospheric conditions. 1" Hg = 1000' of true altitude.

 

Even if the altimeter is working, it does not tell you your true altitude except under standard atmospheric conditions. On a very hot day your true altitude will be higher than it is on a cold day for the same pressure.

 

jcomm,

 

It's almost that same discussion starting all over again! :) Also agree with your points on lift and outer wing.

Oracle, 

 

I guess you are right it has to be under ISA. But this what I was told. So just asking around :)


Ok one more question , I know the answer. 

 

Can you bank and level / climb the aircraft based on cockpit reference ?

Counting the instruments?

I'm confused by your terminology ironmaiden. Regulations aside you can definitely fly visually or by instruments in VMC and exclusively by instruments in IMC.

 

You can navigate and maneuver with great precision just by reference to instruments.

@jcomm,

 

 Forget the instruments for the moment.

 

I mean not all instruments, just don't look at the AI.

 

@oracle,

 

 Nothing confusing , don't look at the instruments.  forget the rules for now. It's just a question .

 

Don't look at the AI (OF COURSE THIS IS ONLY DURING VFR)

But that's what I do, since more than 30 yrs, when flying for real a glider, with the remarkable exception of the string we use in the canopy, useful mostly when I get to fly a new machine, because once you get used to it's sounds and pushes.... you do not even need the string again :-)

 

But you have a big problem if flying on / near mountainous terrain... Then your horizon references can get really disorientating... At least one fellow glider I knew personally died because of that, here in Portugal - btw, only two fatal glider accidents in Portugal since the early 1940s....

 

Pitch attitude, and hence AoA can easily be determined that way, referring to the horizon line, the same applying for bank.

 

In a glider, flying uncoordinated is also easily identifiable by the sounds and that string in the canopy, which is also useful in an helicopter or a twin, or any aircraft without an engine ahead of the cockpit...

 

Since you now have DCS too, you will have an extraordinary chance to test flying coordinated on a powerful prop aircraft, having to use rudder and trim tabs each time you play with power / energy, etc... I mean, in the TF51d...  It is also possible now in X-Plane, to some extent... and I've been playing with that updated Carenado C185F :-)

Yes, mountainous terrain can cause disorientation. 

 

What is the top speed of a glider ? do they have engines ?

It depends on the glider.... the most performant can reach 280km / h or even more!

 

Yes, there are three types of motorizations in a glider... They can be used in pairs, each one per se...

 

- Mother Gravity ( the main source, and the most remarkable one, added by Mother Atmosphere ( in good part the  Troposphere... )

- SSG ( prop (recip or electric) or jet )  --> Self Sustained Glider

- SLG ( prop (recip or electric) or jet )  --> Self Launching Glider

Why would a glider be faster than a 172 ?
