Aircraft can't lift off all the way off the ground

[Goblin88]

In every mission I have to cold start my aircraft I'm getting this problem: My aircraft wont go higher than 6-8 feet.

 

I've double checked my start-up procedures five times in a row, and I am doing everything on point. I tried calibrating my joystick, and changed the simulation "easy fly" option, but I am still getting this problem. Am I a complete fool, or is there something legitimately going on here?

track file will help.

If you can provide a track file of your startup sequence and attempted takeoff I'm sure someone will spot the problem. If you run any single-player mission in which you start from cold start, then quit after your failed takeoff, you will have an option on the debriefing screen to save the track file. It'll be under your Ka-50 install directory.

 

The only things I can think to check are that you're starting both the engines (not just the APU and the left engine, for example) and putting the throttle into the normal position. Before you takeoff with the collective at idle your engines should both be at 90% RPM.

 

Is this happening on every map? Different weather conditions and altitudes can cause similar problems, but they're pretty extreme and not present in most missions.

Added bit about saving track file

[JG14_Smil]

did you hit PGUP twice before taking off?

[Feuerfalke]

Either too little power (as JG14_Smil posted: Hit PageUp twice) or check axes-mapping in DCS.

 

Sometimes 2 axes are mapped to one function and both are mixed up by the game. If that happens, you might have 100% throttle set, but maybe 50% on your left pedal or something. As the latest input counts, you may accidently reset throttle or collective to 50%.

[Goblin88]

Thanks for all the input, I will post a track file and look into some of the other suggestions.

[Goblin88]

Ok here is a track of a typical start-up I do. Same problem. I know I'm doing something wrong, I can't figure it out.

 

I moved my RPM thing up to auto by hitting page up twice. Both engines started up and got to idle within sixty seconds. APU is off and generators, governors are on. I'm just not sure.

I'm doing something wrong..trk

[JG14_Smil]

trk file did not work for me... is the rotor brake engaged?

[Jack McCoy]

The trk file does not work for me either.

[nemises]

Track works fine, it's just been given an (accidentaly) invalid file name...you cannot have ".." in a file name..just rename it / take out one of the "."'s

 

Anyway, have had a quick look , and definately "something" is wrong with your startup sequence as I was also getting low RPM issues after whatching your startup...I'll keep looking tho, as it did come right..the only things I cahnged were to turn Off the EEG Gas test, and play with the throttle....need to check it again tho, and will let you know if I figure it out

 

 

*Edit* - Yep, its the EEG Gas gen test, looks like it is stealing lots of horsepower from the engine...you need to turn this off before operating the aircraft in flight (can one of the hard-hard-core flight procedure guys confirm this ?).

Also, you should VERY MUCH consider turning on the Stabalisation / AP chanels for Pitch, Yaw and Roll before taking off, otherwise the damn thing is like a bucking bronco on takeoff.

 

Try that tho, make sure the EEG Gas Gen test button is off (down), and the PA channels are on, and you should be golden.

 

Good luck, and let us know how you get on!

Sorry about the labeling error everyone.

 

Thanks nemises on looking into it for me, I really appreciate it. I'll turn off my EEG Gas Gen and try it out.

[joey45]

try this....

 

or watch the first producers note about start up.

try this start up.trk

[Goblin88]

Ok, figured it out. Can't turn on the engine generators. Thanks for the help.

 

I'll check it out too joey.

The Gas Generator EEG test is a way to make sure that your temperature limiting is working properly for the engines. With the switch ON, it tricks the EEG into limiting your power much earlier (around 850 degrees EGT or something like that). This is so you can perform the test on the ground without getting airborne. Normally, EGT limiting does not take place until you get up to around 950 degrees EGT. Having these switches ON could definitely cause trouble with taking off, since your power will be much more limited.

just to clarify Goblin they are talking about the EEG gas generator by your "governor control switches".... not your regular generators (by your battery control) that go off the rotors ;)

[nemises]

Yeah, well pointed out GW..I was just hoping he had mis-typed what was meant..

 

Goblin,

The Generators MUST be on...once the engine RPM reaches above 80% , then they supply charge to the batteries (which power the DC items in the Shark), and also supply direct AC power to the AC items in the shark.

Without the generators, you will not have any of the "cooler" in cockpit tools, like Shkval, or the UV26 flare dispensors ;)

 

What I was indicating above is that you must switch off the EEG Gas test switch which is on the Right hand wall at the very rear (next to the EEG govenors)...as A16 has pointed out, the test switch causes the EEG to cut out horsepower earlier than standard so that it can be tested in ground conditions....without the horsepower, the engine RPM dropps badly when you increase collective, the Low RPM alarm sounds, and all of your AC powered items start dropping off as the generator no longer has teh torque required to put out AC power at the correct voltage (ampage??).

 

Basically everything was cool with your startup except for that one switch that need to be turned off again (after you have used it to test the EEG on teh ground if you like! thats whay it is there).
