v speeds

[seed]

is there any v speeds chart for a10c ?

i couldnt find in manual

How do you mean?

;)

 

OT: I recall there being a sort of flight planner, or mission planner of some kind where it calculates the V-speeds. Do a search on the forum.

Yep, there is a handy program created by a forum member that calculates some takeoff data. I don't remember the who/where, though.

 

Alternatively, if you search the forum for the term "TOLD", you should find a .pdf that I created for takeoff/landing data. It was actually done up for Nellis during the early beta, but the speeds are still valid.

thank you for the answer that was very helpful

i also like to know if there is any references for vx and vy and maximum glide speed?

Rotate at 140 KIAS and you will be fine. Ur not carrying 1,000,000 pounds of passengers, cargo and fuel, just 55,000 lbs. max of gas and weapons, lol

i guess it would be useful for takeoff if you are trying to call out your V1 Vr V2 Venr speeds, but ive just stuck with the traditional 140 rotation speed and then climb around 180.

 

for landing its just as accurate to use the AOA as it would be to use a chart to calculate airspeed.

 

sounds too much like a job to start calculating V speeds based on elevation, weight, temp etc. Not trying to discourage you from doing what keeps you happy, but im not going to start paying attention to my N1 gauge to make sure i dont over power on take off/climb/cruise based on temps or higher than normal ISA.

 

Hope you find what you are looking for though!!

Here's a link to the TOLD document that I put together a while back. Check out the post for definitions of the various terms.

You can also use the real A-10A flight manual as the speeds are the same for C model. There should be a link in the manuals and documents thread.

The TOLD numbers in both the utility and my .pdf were generated from the real A-10 performance data. No need to read those spaghetti charts.

There are no "calculations"…v-ref speeds remain constant despite environmental factors and weight (just like stall speeds) when using IAS - thats why they can permanently mark them on IAS indicators…thus, it is a good question. Obviously the poster is a pilot…v-speeds are the FIRST thing a pilot memorizes when checking out in a new type

Maybe in a Cessna or a Warrior, but not in any jet.

 

V1 is a calculated value based not only on gross weight, but thrust setting, flap setting, temperature, headwind/tailwind component, runway length, runway condition, runway slope, and other stuff. To some extent Vr and V2 can also be affected by certain factors and required additives too. Vref is also affected by landing configuration - flap setting and speedbrake position.

 

The calculations for takeoff are usually done by a computer based performance program. Landing data is generated for a range of values, or calculated in the cockpit. Speed books can simplify the process by printing data for common configurations at a range of weights. These numbers can then be adjusted on the fly based on non-standard conditions.

 

In any event, you're not going to memorize the performance data. Unless you're Rainman.
