V1, VR, V2

[fitness88]

On a 9000 foot runway, with just internal fuel in an F-15 what would be the V1, VR, V2?

 

Thank you.

Those terms are AFAIK not used for fighters.

Takeoff run depends on weight and power setting.

 

Maybe this is what you are looking for?

I see this gives you the length of runway needed to get airborne, thanks.

Mainly I'm looking for info on:

 

• 
  
• VR=At what approximate speed with given weight do I begin to rotate? Is temperature, humidity and wind modelled into the sim?

From the F-15C manual:

 

For a normal take-off, having reached a speed of 100 knots, pull the stick half-way back for over one second and hold pitch attitude at 10° after nose wheel lift-off. To minimize ground roll, set 12° pitch attitude after nose wheel lift-off. WARNING. EXCESSIVE AFT STICK (QUICK PULL OR MORE THAN ONE-HALF AFT) IS NOT RECOMMENDED AS IT CAN LEAD TO EXCESSIVE NOSE WHEEL LIFT-OFF SPEED AND HIGH PITCH RATE.

 

Temperature: yes

Wind: yes

Humidity: From what I understand: sort of. It does not vary with e.g. flying through clouds.

Here's some very nice charts for the F-15 with the engines we have modelled.

 

Check page 37 (section B3-19) for basic takeoff parameters by weight without conformal tanks. The pages before that contain charts showing safe distances/speeds for takeoff/landing by weight as well.

Eeeeh, it would be nice if someone would have to make something like WDP for DCS.

That's great thanks...time to read the manual again!

A lot of great info here! You're saying this is all modelled into DCS F-15?

[SinusoidDelta]

It certainly is, comparing the DCS F-15C and -1 App. B charts it is surprisingly accurate. Test it out for yourself:D
