T-45C Goshawk realistic HUD and awesome video :)
SpazSinbad:
neutrino, as people are saying here and elsewhere 'carrier landings sure got much more doable in FSX now' thanks to your team's sterling efforts.
neutrino:
Spaz, thanks ::) I just posted on another forum something that you might find interesting, you can correct me if I am wrong about something, I used your pdf file as a reference for the T-45C. This was the original question:
--- Quote from: jmig ---That is a nice video. One question, however. Does the T-45 land without flaps as shown in the video? It would seem to me that you would want to use flaps on landing?
--- End quote ---
... And below is what I posted:
The correct thing of course is to land with full flaps, but I did not use flaps at all in the video. The reason is that Dino's T-45C reaches it's optimum approach angle of attack (about 8 degrees or the velocity vector centered in the E-bracket) at a very low speed of about 105 kts with full flaps. The real T-45C landing speed (with full flaps) however is about 120 kts. So I wanted to land at the optimum approach angle of attack AND at the real T-45C landing speed of 120 kts. I found that this could be achieved with flaps UP (no flpas) and speed brake ON. It also helps to land at a higher speed if you land at max fuel.
This is a screenshot from the video. You can see that the aircraft is at the optimum AOA (yellow donut on the indexer and velocity vector in the center of the E-bracket) at 119 kts:

neutrino, I cannot speak for Dino Cattaneo but we had an e-mail conversation about that aspect (slower than advertised IAS for Goshawk in FSX). The 'Goshawk Gouge' advertises the IAS for different weights in 500lb increments (I think) for Optimum AoA (I'll have to check). Which is best to use? IMHO I think using the conditions set by the Fsim model designer is the way to go - others may have a different opinion. Perhaps Dino will go back to making modifications to the Goshawk. Why don't you contact him about it? He must be pleased with the new HUD - which shows the inaccuracy (remember before the NEW HUD, the real world IAS could be gleaned from the aircraft tables only).
Carrier Landings are carried out in a standard configuration. Anything else is an 'emergency' of some kind. The LSO would make special consideration for the 'emergency' - the pilot also. A Goshawk would not carrier land unless it could do so in FULL FLAP. Not sure if they would practice ship carrier landings in any other configuration except hook down. It can land with full fuel so that is not an issue. Always the IAS will be whatever the Optimum Angle of Attack is for the given weight. The chart exists to allow a rough check by pilot that his AoA indexer is working accurately.
The LSO needs a standard configuration to enable him to gauge the approach in the same conditions for any aircraft type. If that aircraft is at Opt AoA then it looks the same to him. This is important. The LSO uses the aircraft attitude for a physical frame of reference that is very accurate. He knows more than the pilot - no kidding. By inference then if the aircraft landing config is changed from the standard then that is a different frame of reference which the LSO has to allow for and likely will not be so familiar with (except ashore).
My Goshawk landing technique is to use FULL FUEL to get the slow Opt AoA up - the engine RPM is up also.
REQUEST: Would it be possible to add .PDF to the file types that can be added as attachments to this forum please? PDFs allow documents to be the same - unlike .DOCs for example where formatting can change radically. In any event I'll make a .DOC out of a TRAWNG PDF and attach it soon (if the conversion from PDF to .DOC goes OK but it does not look good due to a 'funny' font being used in the original PDF).
HMMMM. :o I did not notice that .ZIP is a possibility so here is an edited GOSHAWK 'how to deck land' PDF zipped. It does not have everything but nothing ever does eh. More PDFs zipped later....
JamesChams:
Mr. J. R. "neutrino,"
Thanks again for the fine work you've done to this...
The only thing I found missing in your Aircraft.cfg is the correct TAILHOOK settings for Mr. Dino's model.
You can find the settings here: Aircraft AI Carrier Configurations v1.9 by James F. Chams
====================================================
T-45C Goshawk v1.85
---------------------
Modify this "Aircraft.Cfg" File with the statements below:
...\Microsoft Games\Microsoft Flight Simulator X\SimObjects\Airplanes\Boeing_T45C\Aircraft.Cfg
// Modified by James F. Chams @2009.
// =================================
[tailHook]
tailhook_length=2.5
tailhook_position=-15.6, 0.0, -2.63 // -18.6, 0.0, -2.63 // Modified to align correctly with the Tailhook
cable_force_adjust=1.5
Launch Assist in coded into the model's (.mdl) file and is therefore NOT needed here.
====================================================
Thanks again! 8)
SpazSinbad:
James, thanks for the 'hook/arrest' mod. Can you explain please briefly? Thanks.
Here is the TakeOff/Landing Weight IAS chart for the Goshawk (AFAIK). The other than full flap settings for landing are for ashore 'emergency' or otherwise 'practice' landings. To my knowledge there is no provision for landing onboard other than with full flap.
