Edge of space is 330,000ft, however i don't really see it happening at 60,000fy considering the afterburner will be constantly necessary and once you run out of it and it's in cooldown you will lose altitude.

Hi, guys!

 

I flew the DCS F-5E last night and got it up to around 51,120 feet in straight and level flight but I have the afterburner on, unlimited fuel ticked and 1% fuel left!

 

Cheers,

Vincent

Hi, guys!

 

Question for you, is it possible to get the F-5E to the edge of space which is around 60,000 feet? Thanks!

 

Cheers,

The supersonic zoom climb profile described in the T.O. 1F-5E-1 Appendix I page A8-22 works for me. Can get the F-5 to 63000ft+ according to Tacview, just can not stay there... As already noted, not really the edge of space.

Does the two engines work at that altitud? Phantom´s J-79 works over 60.000 ft. according a former spanish F-4C pilot I asked about time ago, but I think F-5E´s engines should flameout. Probably flameouts aren´t simulated in Belsimtek´s F-5E, isn´t it?

Never flamed out at MAX thrust, just as advertised in the T.O. Thrust does deteriorate when IAS is low enough, as per T2 sensor and T5 modulation it seems.

It makes sense, engine don´t flame out if full afterburner is engaged. But engines should flame out if throttles are in MIL or less at very high altitud and low KIAS, I suppose. Flame outs and compressor stalls are not simulated in this plane right now, true?

As I understand compressor stalls are not fully implemented. It seems to be possible to carelessly handle thrust levers at high altitude witout ill efects.

That´s what I though. I have seen videos of Leatherneck´s Mig-21 suffering compressor stall and flame out after spinning, but I suppose that right now Belsimsek´s F-5E is not as realistic as Leatherneck´s Mig-21
