1. I have version 1.0. Is this the latest?
No. This gets a bit confusing! The latest version is “v1.1″.
The chronological sequence is:
v1.00 Release version
v1.01 public beta patch
v1.02 public beta patch
v1.03 public beta patch
v1.01 final patch (sic)
v1.04 final patch
v1.05 final patch
v1.1beta1-5
v1.1 final
v1.1 was formally rereleased and includes both DOS and Win95 versions on the
same CD.
v1.1 fixes the ECM light bug, improves framerate for ground attack, introduces
mirrors, gives much better views including dogfight, selective friend/enemy views,
instrument glance and ground padlock, increases rear visibility, increases RWR
functionality, enables the Mig-31, enables screen size autoswitch, etc. etc. and
fixes various bugs introduced during the patching process!
You can the v1.1 patch for the Win95 version from:
http://nwlink.com/~mikej/patch.html (American version)
http://ccue.wlv.ac.uk:8080/~in1053/Welcome.html (European version)
The only differences between the two versions are the picture shown in transition
between flight planner and mission, and the support numbers.
Patch files also appear in SSI’s section in GAMAPUB on Compuserve, and on
their WWW site www.ssionline.com.
Don’t forget to delete your old SU27.INI file before running v1.1 for the first time
- copies in both your Su27 and WINDOWS directories.
If you bought v1.0 Win95 and want v1.1 DOS you will have to trade in your CD
to get it.

2. The manual mentions “x” but I can’t get it to work.
It seems certain features were planned but didn’t make it into v1.0. They are all
present in v1.1 (and some extras too).

3. When did v1.1 come out?
End of May 96.
v2.0 is planned for autumn, DOS and Win95. A few hints as to contents so far:
8-player networking, Mig29, texture-mapping via Direct3d, better sounds.

4. What is the upgrade policy for owners of v1.0?
Patch files are available on BBS / Compuserve etc. However these will only
upgrade the Win95 version, not give you the DOS version as well. For this you
will need a new CD.
From the USA send $15 and your old CD to:
Su27 Upgrade
675 Almanor Ave Suite 201
Sunnyvale
Ca 94086-2901
In the UK phone 01444 246333 for information – the current deal seems to be to
send your old CD and a cheque
for GBP5 to:
MINDSCAPE (TECHNICAL SUPPORT)
PRIORITY HOUSE
CHARLES AVENUE
MALTINGS PARK
BURGESS HILL
WEST SUSSEX
RH15 9TO
In the rest of Europe phone +44 444 246333 (which is of course the UK
number).
v2.0 will be a new product, not an upgrade or patch. You will have to buy it.

5. Is ECM broken?
No. The ECM light was broken in v1.0, now fixed.
Sorbitsya ECM pods are automatic and switch themselves on and off. This means
you have 4 levels of ECM:
None
Sorbitsya only
Onboard ECM only
ECM and Sorbitsya
Not even the last combination is going to save you 15km away from an S300 site.
The above was determined by careful testing in controlled conditions against 3
SAM types.
Some example ranges of engagement:
TARGET: inbound Su-27 at 2000m altitude, 1120km/h.
A) S-300PMU SAM system.
Range of engagement (SAM launch)
No ECM / No Sorbtsiya: 69.0km
Sorbtsiya but no ECM: 54.1km
ECM / No Sorbtsiya: 62.1km
ECM and Sorbtsiya: 45.5km
B) KUB SAM system
Range of engagement (SAM launch)
No ECM / No Sorbtsiya: 24.4km
Sorbtsiya but no ECM: 17.9km
ECM / No Sorbtsiya: 20.0km
ECM and Sorbtsiya: 14.7km

6. I cannot get the lock key (TAB) to work.
You have to hold it down, sometimes for up to a second. This is deliberate,
realistic modelling of the performance of the WCS, not a bug.

7. Missiles don’t fire.
They seem to “stick to the rails” sometimes, don’t they? This is because they take a
couple of seconds to arm when selected – that realism thing again. Wait, or hold
down the fire button a bit longer.

8. There is no six o’clock view.
We are told that this is because the real Su27 has no 6 o’clock view. Fair enough,
although this is disputed! v1.04 onwards extended the view angles 30 degrees
further aft, but only if you are pulling less than 6g.

9. How do I get the HUD to show knots and feet?
You can’t. That realism thing again. The preferences option only affects
measurements in map mode. The HUD and instruments always show meters and
km/h. Note that the HUD shows true airspeed (TAS), the dial shows indicated
airspeed (IAS).

10. It is jerky even on a P133.
This is now officially called “the stutter”. For a long time SSI were unclear what
users were complaining about – at first Win95 took the flak and then the myth
arose that it was unique to Pentiums. Neither of these is true. It took a visit to my
house by Jim Mackonochie and Steve Whittle to realise what was going on – once
identified, they realised the problem had been present on their machines all along.
The stutter is subtle on 486s, and as the game was developed and optimised for
such machines by the Moscow programmers, it was overlooked. It is due to an
interaction between the graphics and flight maths routines. It is more
noticeable/intrusive the faster the machine, and some players seem psychologically
unbothered by it. It was identified too late to be fixed for v1.1 but SSI are hard at
work on a further patch.

11. I can’t get Kh-29 air-to-ground missiles to lock on no matter what I do.
Kh29s do NOT lock onto a radar image. They are optical. Use the radar mode 4
(zemlya) to find the target, then turn the radar OFF and move the round circle with
the dot on it, which represents your missile seeker’s line- of-sight, to the target
either by maneuvering the aircraft or with the direction keys. The MFD shows you
what the missile is looking at. When you see the target in the centre of the MFD,
lock on with Tab, and away you go.

12. I get disorientated in padlock mode.
That little mini-HUD that you see in padlock mode is always orientated so that it is
at the side of the screen closest to the nose of your plane. Basically, you need to
roll so that it is at the bottom of the screen and then pull up on your joystick.

13. The Kh-31 antiradar missiles don’t lock on.
We are told that contrary to what is says on the manual, the Kh31 can only lock
onto a fire-control radar, i.e. they DO lock on but only to a radar that has already
locked you up (and therefore expect a SAM already on the way). From a
sufficient distance they are therefore useful. Close to, you will probably die.
Suitable strategy is to fly into range of SAM. Have your radar off. As soon as you
are locked up, lock onto the SAM and fire. Then immediately go fully defensive -
chuck chaff / flares, break turn, get low, split-S, get lower still, and repeat as
necessary.
You cannot lock onto EWR or search radars. This is said to be realistic, but has
been disputed.

14. How do I get computer controlled planes to launch more than one bomb or
missile at a surface target?
Put more than one target waypoint onto the target in the flight plan. This still is
insufficient to get a simultaneous multiple launch e.g. at a ship, where it is most
needed to break through anti-air defences. The plane will fire, pause, reorientate,
fire again etc.

15. Missile performance (range) doesn’t match the specs in the manual.
The specs in the manual are the manufacturers’ maximum performance figures. A
sales pitch. No missile ever performs up to these levels in actual combat. The
maximum ranges in the sim are probably reasonably realistic, perhaps a bit
pessimistic. The ranges were upped slightly in the v1.1 patch.

16. I always miss with the R77.
This missile’s own radar only goes active 15km from the target. Until it is that close
(you have to guesstimate this yourself) it requires guidance from your radar i.e. you
have to keep the target locked up until then.

17. I can’t sink the ships with the antiship missiles.
Have you watched the ships in action as your missiles approach? They undertake
active defence with SAM and AAA. You have to swamp or surprise the defences.

18. I can’t find the enemy planes with my radar.
Radar is modelled quite nicely in this sim. Low flying incoming small bogies are
especially hard to lock up. Make sure your radar is pointing in the right direction.
I.e. don’t expect to lock up bogies at 50m alt at range of 15km if you are at
15000m alt with radar pointing straight ahead. Friendly AWACS and EWR
obviously help as their information is uploaded to your Su27 by datalink.

19. How do I padlock a runway?
You have to be in NAV mode NOC or BO3B. Then look at the runway and push
* as usual.

20. The keyboard card is wrong.
Yup – fixed in v1.1. E is active jamming. A is autopilot. Ctrl-E is eject. S cancels
accelerated time. And Ctrl-H does something weird to the palette.

21. How do I dump fuel / refuel?
The L key dumps fuel whilst you are in the air, and refuels you whilst you are on
the ground. But it is realistic – it does so in real-time, i.e. slowly. It takes about five
minutes to refuel to 90% from empty. Ctrl-A will accelerate this process, but
meanwhile ……

22. How do I get the airshow SU27 into one of my missions?
Classify the mission as type “Training” using Flankers with Sortie type “Nothing”.

23. How do I do the Cobra? The K key doesn’t work.
You are going too fast. Try flying level at 450km/h, then push K. See? A prize for
anyone successfully using this in combat, as in “I’ll pop the brakes and he’ll fly right
by”. (Hint: you are in the wrong sim. Probably the wrong universe. Please close the
door as you leave.)

24. I have created my own mission, but I can’t start it.
(i) You have to save it first before you can start it.
(ii) To fly yourself in the mission make sure that you have one Flanker designated
as “Me”. You can only do this on a flight leader of “your” side.
(iii) If you have assigned a start time after the default to “Me” you will have to
watch the “prequel” unfold before you automatically jump into your plane at the
designated time.

25. Where can I get more missions to fly? Or even a campaign?
Check out the unofficial Su27 home page on WWW:

http://nwlink.com/~mikej/su27.html

or its mirror: http://ccue.wlv.ac.uk:8080/~in1053/Flanker/su27.html
Also try Eric Joiner’s: http://www.gttweb.com/SU27/index.html
SSI have also come out with an updated mission suite, SU27_MIS.ZIP in the
Modern Combat section of FSFORUM on Compuserve, and on the above
WWW sites.
It is strongly recommended that you join the flanker e-mail list. There are about
10-20 posts a day dealing with tactics, flight experiences, new patches, and
interaction with the programmers themselves. To join, simply send an e-mail
containing the text-line
subscribe flanker to: majordomo@wlv.ac.uk
Majordomo is an automated mailing list server, not a human. You will receive full
instructions as to how to post to and unsubscribe from the list. Save them
somewhere safe! Please note that once you have subscribed you will immediately
start to receive e-mails which at first glance seem to be written to you personally
from complete strangers. These are of course the postings to the list, and they can
be distinguished by the Header “To: flanker@wlv.ac.uk”;.
For live chat there is irc: #flanker-o-club on DalNet – point your favourite irc
program any DalNet server, e.g: cin.dal.net. Find out more about irc and DalNet
at http://www.dal.net.
Finally, there is HMASP (Higher Military Aviation School for Pilots), the Russian
equivalent of Top Gun. You will find further details at
http://nwlink.com/~mikej/HMASP/hmasp.html. A new mission to fly against the
clock every weekend, submit your TRK file and have your performance scored
against everyone else. Are you the world’s best virtual Flanker pilot? Or the
worst?.

26. What are all the new views?
Left shift plus a view key will cycle only through enemy aircraft / objects. Right
shift plus a view key cycles only through friendlies. Ctrl-shift-Fkey is an allowed
combination, to cycle backwards.
Right Ctrl key accelerates object panning / rotating with keyboard arrow keys
twofold.
Select a plane with F2 or F5, then the F9 key will switch to dogfighting view -
cycles through a view from the original plane towards other planes within visual
range (6km?). You can use R-shift and L-shift F9 as described above to choose
friends and foes.
Tilde ~ key now allows you to switch visual padlock between multiple planes in
your current field of view, so long as you have not locked them up and you are in a
close air combat mode.
* (star/asterix) key allows you to visually padlock ground target. Whilst in ground
attack mode, put the circular target designator in the HUD onto the target and lock
using *. This is the CCIP marker with appropriate munitions, otherwise it is the
centre circle. The effect lasts about 2 minutes.
Keypad 0 allows you to quickly glance at instruments no matter where you are
looking. Works only as long as key depressed. Absolutely invaluable for
dogfighting.
The backspace key now duplicates the Caps Lock key – weapon selection.

27. How do I get my Thrustmaster kit to work?
Don’t ask me! I use Suncom.
However, try the following. If you know better, tell me.
(i) Calibrate the joystick from Win95 control panel. DON’T choose Thrustmaster,
select 3-axis, 2 or 4-button stick instead. (4-axis if you also have pedals.) Then
select Thrustmaster from Su27 Preferences.
(ii) If you have ACM gamecard and Soundblaster there may be a conflict in game
ports. Uninstall both, then reinstall first ACM then the Soundblaster.
(iii) Pick up your .M50 and .B50 files from Mike’s WWW site

http://nwlink.com/~mikej/tm.html

28. My wingman doesn’t follow me on take-off.
If he sees you making anything less than a picture perfect take-off he aborts. It’s
too dangerous up there to follow a flight leader who doesn’t know his stuff! Also,
he doesn’t want to slam into your tail. Pull back steadily on the stick, don’t hesitate,
don’t let the nose drop. Don’t pull too high an AoA before take-off velocity.
Finally, if you are heavy with 100% fuel on board, you will need to light those
burners.

29. How do I set my throttle to full idle?
Go to the joystick calibration screen in Su27. Close your throttle to minimum.
Now notch it forward a bit, so that the blue ribbon is visible below the min RPM
line. Now push the min RPM button. Repeat as necessary. You should now be
able to throttle down to true idle.

30. Can I fly GAI missions?
Yes. Put yourself on a runway, first waypoint as take-off, mission type GAI. The
mission will start without you. As soon as EWR picks up bogies or they approach
within 10km of your airfield (visual pick-up) you leap into your plane on the
runway.

31. How do I find out more about fighter tactics?
(i) Join the flanker e-mail list (Q26)
(ii) Buy Fighter Combat, Robert L. Shaw, Naval Institute Press, ISBN
0-87021-059-9, from http://www.books.com. A serious book for a serious sim.

32. How do I go H2H?
(i) Play on a LAN using the built-in IPX networking.
(ii) Over a modem. For this you need the Win95 version and the Win95 Plus
Pack’s dial-up server. Use this to network together your 2 computers using IPX
protocols, and then effectively you have a LAN-over-a-phone-line. This works
very well.
(iii) Trying to get TCP/IP working between 2 machines over dial-up connections
to the Internet is a pretty hopeless task – anything but the fastest ping times lead to
dropped connections.
(iv) There are some reports however of success with the DOS version and Kali
over the Net.

33. What are the remaining bugs in v1.1?
Well here are a few – not a comprehensive list.
(a) The stutter
(b) AI responds very poorly to incoming missiles Beyond Visual Range – planes
just fly straight and level and dump chaff and flares.
(c) Your wingmen can catch up to you and pull into formation even with identical
loadouts and fuel levels while you’re in AB. This shouldn’t be possible.
(d) Computer aircraft have advantages in power thus are harder to fight in the
vertical.
(e) Computer aircraft apparently burn less fuel than the player’s aircraft.
(f) AI pilots never lead turn or try to create lateral separation before the merge, ie
they are not aggressive in guns only fights.
