How to Find True Airspeed in Flight | True Airspeed Calculation

[@pushing2throttles]

Best True Airspeed lesson I've ever seen. I promise you!

"tear-assing up the bay, dodging sailboats and busting regs" well said sir ;-)

[@tomdchi12]

As always, that's a great illustration of what's going on!

Hi Dan. I’m currently studying for the IFR exam. I’ve purchased the Sporty’s IFR training video series and gone all the way through them. I stumbled upon your IFR training playlist and am working through it. I just have to tell you that it’s superb! Thank you so much for the effort to produce these videos. They’re fantastic.

Sheppard air helped me

[@bullseyes1983]

It is so simple to understand it this way. Great job as usual.

[@jakew9887]

Excellent presentation. Thanks

[@cmurphy3748]

01:20 It looks like you aligned the pressure altitude with -15* C, instead of positive 15 C. Am I seeing that correctly?

[@anthonyescribens]

I noticed the same. @FlightInsight, can you please confirm.

[@TheHURIT]

Thank you so much! Itʻs much clearer now!

add 2% of your IAS per thousand feet of altitude and you will have the TAS

[@jimallen8186]

What regs were you busting?

[@holylee30]

What is TAS for? As a pilot why do we know TAS or how can we use it?

[@PilotChris]

It’s used for Navigation - You’ll use your TAS when doing flight planning to determine what your expected Ground Speed will be, allowing you to determine time enroute. Once in the air you’ll want to calculate your True Airspeed to see if it is the same or different than what you had assumed when doing your flight planning.

[@davidlourensz4822]

I think on your first example, you had 1000' Press Alt set against +15C, not 400' Press Alt set against +15C. which gave a TAS of about 105 kts as you said. But I think it might be more like 103kts at a guess. As a result, your TAS would have been lower than you indicated which wouldn't have made sense. But I guess there is a lot of error in reading and setting things, such as the altitude read-off at 29.92 and as you say the slide rule in the ASI is rough.

air doesn't flow through the pitot tube

[@CatarineausArmory]

I am going to need a little extra help as the great example was not illustrated in crayons and stick figures....Pull back houses get smaller, push forward they get bigger, who cares what TAS is? Fuel is burned based on ETE (time enroute), ETE is based on GS. GS is displayed as you have shown. GS and ETE is what matters when it comes to fuel remaining at destination. Yes, altitude and tailwinds help the GS and burn. What am I missing? Thanks, good presentation but I can't understand why we need it when it doesn't change the amount of fuel in the tanks.

[@flightinsight9111]

It’s good to know what airspeeds your aircraft will “true out” at at certain altitudes, so when you’re flight planning, you have a relatively constant figure to apply against different wind scenarios etc

[@CatarineausArmory]

@@flightinsight9111 Thank yo sir. I will buy that...although, again, it seems like an additional step to the process of looking at the winds and just subtracting/adding/interpretation of that amount. It ain't you man, I am seriously asking to assist my understandings.

[@GeckoTH]

@@CatarineausArmory GS may displayed inside the aircraft (depending on your avionics), but that doesn't help you when you're on the ground planning for the upcoming flight. For that, you'll need to know or calculate your planned TAS based on your planned altitude and the performance charts in your plane's POH, and use that along with forecasted winds aloft to calculate an estimated GS. This video does an excellent job of explaining how Indicated Airspeed, True Airspeed, and Ground Speed all relate to each other and gives a great simulation on seeing those concepts come together in the cockpit.

[@CatarineausArmory]

@@GeckoTH Now that makes sense. Maybe I have been to spoiled with the flight plans already calculated and handed to me...

[@kingston5469]

I did not want to ruin the like count of 747, but your video was so good that I had no choice

[@paranoma87]

Ummm. Is this Dave Grohl narrating?
