rudder question

Many thanks, SpazSinbad, learned much from your post.

--- Quote from: SpazSinbad on August 03, 2009, 10:51:59 am ---Excerpt from the Super Hornet NATOPS (sorry don't have Hornet NATOPS) may help explain how rudder is really only effective in very slow IAS (and at circuit speeds) instances and otherwise not so effective or limited in high speed flight:
"Some traditional directional control capability is returned at low airspeed and high AOA only when
the pilot applies lateral stick and rudder in the same direction. This feature starts becoming effective
only at airspeeds below approximately 225 KCAS and above 20° AOA but is most effective at
approximately 120 KCAS and 34° AOA. Enabling this feature outside of these conditions would
compromise departure resistance. When this feature is enabled, the sum of lateral stick and rudder
pedal command is no longer limited to a value equal to a full lateral stick input. The excess roll
command is fed to the directional axis to command sideslip. For example, adding full rudder pedal with
a full lateral stick input provides a maximum roll and yaw command. Alternatively, adding lateral stick
to an existing full rudder pedal input has the same effect. The resulting aircraft motion is a highly
controllable nose-high to nose-low reversal.
At high airspeeds, symmetric rudder deflection is reduced and the rudders are toed in to avoid
exceeding vertical tail structural limits.

Thats how to execute the Pirouette which is a preprogrammed manouver that the Superhornet can execute(F/A-18 A/B/C/D do not have this feature). The pirouette is used during ACM to do very tight turns at low speed. Its modeled on the VRS superhornet.

bushwhacker, I'll just repeat this here for information about carrier landings. On other threads there are more pointers about carrier landings and of course on the web by googling you can find more current information / stories about Hornet carrier landings:
"Other threads on this topic exist here on this forum. My advice would be to practice your landings on a regular airfield using the devices there for glideslope as indicated in that marvellous FSX Blue Angels explanatory video. Terrific work by all concerned. The video states that it is all 'practice, practice and more practice' (or words to that effect). I cannot recommend this video enough - it is an excellent tutorial. Once downloaded go to your internet cache to save the .FLV video about 115Mbs to your file system so it can be watched over and over if need be.

Doing FCLP ashore takes some of the distraction away so that you can concentrate on some parts and then take that skill to the carrier. If you set up the strongest wind (35 knots) and have it going straight down your runway, without any turbulence, then this can simulate the carrier conditions; without the pressure of the ship. Practice your control of the aircraft in the landing configuration at a few thousand feet so that you get a chance to learn what it will be flying like with the trim well set. Then the power controls your rate of descent, power always needs to be added to maintain optimum angle of attack in a level turn etc. IMHO carrier landings would be the most difficult achievement in FSX - but of course others may differ.
This thread is more about carrier landings than 'brake problems':"

bushwacker:
thanks again for the info spazdinbad,
i guess in this case two out of three IS bad! I get glideslope, speed, but occassionally my lineup if BAD. I always assume I can save it at the end, but i usually end up a flaming oil spot!! always thought, if only i had a little rudder ;D
will work on trying to get it right, further out.
I have watched that video, great stuff. I have practiced, hour after hour after hour. I feel confident about landing, just not very polished though. something tells me, if there were a greenie board, i'd be crawling around the bottom.
no rudder on landing....so it was pilot error all along! ::) who would've thunk it!
thanks for the input.

BushWhacker (great tag), I'm glad you are having fun. Agree get your line up correct as far out as possible. Crossing the wake (if you are doing a carrier circuit) is essential to be able to line up on the angled deck (on the right of the wake of the carrier which is only a 'lineup for the axial deck') early. Otherwise the problem of liningup on the wake at first, then having to get over a long way to the right, just compounds the other two issues you have to deal with. Have fun & no rudders. BTW at last second over ramp, if you are slightly off the centreline (and I mean only slightly) but otherwise parallel with the angle deck centreline, then you should be able to arrest OK without crashing (all other things being OK). Making the 'over the ramp last millisecond correction' often is the crash cause, especially if rudder is used. No rudder - but I said that. ;D
