Silly question from a BVR noob

[dooom]

If my SU27 is equipped with a R27ER with range of 70km - how the heck can i employ the missile if the LA launch authorization is so much shorter than that?? It seems everytime i lock on to an ea, i do not receive LA until visual range or close to it.

Hi dooom. It is a common question. The 70km range for the ER noted in the in game encyclopedia is a max range assuming all the best conditions. For example, on a large transport at high altitude.

 

The higher you and/or your target are, the longer your range. Also, if the contact is turning and not flying straight at you the, the range will decrease.

 

Try a search of the forums on BVR, also notching might help you.

Also check Ironhand's tutorials on the subject. It's very helpful.

thanks guys - i also just learned the hard way that tgt aspect really matters:doh:

 

That said, two other questions (this is LOMAC vanilla 1.02 btw)

 

1. what is the difference between EOS and radar in terms af detection range??? I presume EOS is close only...

 

2. will engaging ECM pods on wingtips for su27 help against HAWK missiles at altitude or attract them?

Missile range

 

When talking about missile max range it is important to understand what this actually means.

If we keep it really simple now and skip all discussions of Rmax/Raero etc.

 

An a2a missile that is stated to have a maximum range of 70 km can actually never fly 70 km over

land and hit a stationary target. What is meant by 70 km maximum range is that if you have a

target locked 70 km in front of you and fire a missile, the missile might hit if you have absolutely

optimal conditions, those are:

 

• Both you and your target are flying straight towards each other at reasonably high speeds.
  
• Both you and your target are flying very high (think 10.000 m or above)
  
• Your target keeps flying straight towards you during entire missile flight.
  

 

These numbers such as 70km may be given with some marigin of error, so 70 km could likely

also include some small room for target maneuvering, but nothing like turning more than a few

degrees. (probably<10º).

 

• The more your target diverts from the straight nose-to-nose flight path the longer path your missile has to fly.
  
• The lower closure the target has to you, the slower the closure between the missile and the target.
  

 

 

Radar vs EOS range

 

I don't know the range of the real systems, so I can only speak for the game's implementation.

Take the Su27 for example which has both a powerful radar and EOS. Aspect and engine setting

(AB flames are huge targets for EOS) play key roles.

 

Head on you can detect targets a2a with radar up to about 120 km. (HI prf)

Head on you can detect targets a2a with EOS up to about (Im guessing) 15-30 km (depending on targets throttle setting)

 

Tail on you can detect targets a2a with radar up to about 40 km. (MED prf)

Tail on you can detect targets a2a with EOS up to 30-80 km (depending on targets throttle setting)

 

Numbers above are for standard MP fighter type targets. Bigger targets can vary by a lot!
