As for the 15 and A-10 requiring more speed to take off, I didn't notice it, and I flew the A-10 and 15 for about 2 hours. The runways seem a lot more bumpy but not much. Next time I fly I'll really look for that.

I don't need more speed in the Hog, but its a little slower to accelerate down the runway. Weight and drag effects from the weapons also seem to be more pronounced. I like it. :icon_supe I guess I'm gonna keep 1.12 and wait for the hot-fix to my RHAW.

What speed do you normally rotate at in the A-10 and F-15 and with what kind of load Goya?

 

F-15: usually 3 tanks, 6 120s and 2 Sparrows, rotate at 190 or so.

 

Hog: usually 6 Mav-D and 4 Rockeyes, rotate at 150

 

That was before 1.12.

Those are very fast speeds already. Rotation speed for a loaded F-15 should be about 150 KIAS(no flaps) and for the Hog about 130(with take off flaps)

 

Remember... rotation speed is just that...the speed where you rotate the nose to the take off attitude and let the plane fly off the runway.

A-10, 6 AGM-65Ds, 2 Mk.84s, 2 Mk.20s, 2 AIM-9s, and an ALQ-131. I rotate at about 120 with no flaps. I am very gentle with pulling the nose and just wait to see a positive rate on my VSI. She sure takes a while to accelerate now with that load though. Seems accurate. :D

You get the nose off the ground at 120knots with that loadout?

LOL dude thats too much wieght. I only carry 1 tank. Its more than enough and I cant see how you can take that much wieght around in a such small pieace of the world. 3 and you could ferry yourself from black sea to the gulf in one flight. But you cant dogfight.

Dude. You fly your plane, I'll fly mine.

Yup...she just kinda wallows for a little while. I pull the nose slowly to avoid the "airbrake" effect from the fuselage. :D

Goya,

 

Just tried the Eagle with 8 AIM-120s and 3 tanks, full fuel load. With no flaps I rotate at about 110...positive rate at about 165-170.

Posted

110 is too slow for Vr... real world numbers are more like 135 for a medium weight and 150 for max weight with full afterburner. After Vr it should normally be a few seconds before lift off at most.

 

The A-10 is normally configured with flaps for take off.

 

One thing I notice in online flying is that most people rotate at way too fast a speed compared to real world... some even accelerate on the runway and rotate at the end doing well over 200 knots which would exceed tire speeds on the real jets.

Posted

Exactly, or at least kill the tyre life...but in sims, we get a shiny new jet every time! ;)

 

There's plenty that should be done (but isn't) in sims to prolong aircraft life span - people will happily pull beyond the airframes G limit, fly all day at 104% etc. I like to try and moderate myself to what what be done IRL, otherwise I feel instinctively bad for the poor old 'plane!

I thought it seemed a little low, but I pulled the stick back gently at about 100, and the nose came up at 110. I have just been pushing the envelope on both jets to see what I could get away with...that's why I wasn't using flaps in either case. :D

So I must be the only one that at the end of a mission keeps engines on for a few minutes after taxi before shut down to cool them off :D

Never forget that World War III was not Cold for most of us.

I have a book where it staes the F-15's with typical combat load (AA) lift the main gear at 100kts. its not too far off.

Bear in mind that this is relaxed flight model and we realy cant complain over its limitations of low speed envelope simply because this midel is only an average oproximation of the real thing. The error is greater at low speeds.

What book is that?

 

lifting the mains at 100 would mean rotating at about 90 which is the same Vr as a King Air turbo-prop so that number is not right.

Im going to quote exactly:

 

Great Book of modern warplanes, edited by Mike spick

page 181, nex to a picture it says:

"Right:36th TFW F-15C's practice a formation take off from a west german autobahn. Nose up normaly takes place when the eagle reaches a speed of 100kts"

 

Then on page 176 it says:

"Below: A 32nd TFS F-15A leaves the camp New Amesterdan runway at a speed of 135kt's after a takeoff run of only 900ft(274m)"

 

This book is a colection of previous seperate editions of "A-10 Warthog", "F-16 Fighting falcon", "F-14 Tomcat", "F-15 EAGLE", "F-18 Hornet", "Americas stealth wasplanes", "Harrier", "Europes new fighters", "Migs" and "Russias Suckois" all previously edited by various writers.

 

So Youll also find these quotes on the standalone "F-15 EAGLE" By Michael J. Gething

That first quote says nose up at 100 knots, but it doesn't say anything about the mains. ;)

Ah crap you are right. Theres a misunderstanding of terminologies here. Over here main gear is any that suports the aircraft wieght directly and secondary gear, any that for example keeps the aircraft from flipping sideways like the U2, Harrier and Gliders (probably where I got the term, Ive had introduction briefings prior to the flights I had).
