Precog Posted June 24, 2018 Posted June 24, 2018 Im surprised by the almost not existent differential braking in the hornet. Taxi the hornet at taxi speed and apply full right or left brake...barely any movement to either side. Bug? Check out my 'real world' video series [sIGPIC][/sIGPIC]
WindyTX Posted June 24, 2018 Posted June 24, 2018 Try turning off the NWS first and then try it. Sent from my Moto Z (2) using Tapatalk I7 3930 4.2GHz ( Hyperthreading Off), GTX1080, 16 GB ddr3 Hotas Warthog Saiteck Combat Pedals HTC Vive, Oculus CV1. GTX 1080 Has its uses
escaner Posted June 24, 2018 Posted June 24, 2018 The bug would be in the other planes, where you cannot control differential braking with NWS. [sIGPIC][/sIGPIC]
WindyTX Posted June 24, 2018 Posted June 24, 2018 The bug would be in the other planes, where you cannot control differential braking with NWS.What I mean is if NWS is engaged it will keep the aircraft straight ish so if you want to see the differential brake effect turn off the NWS 1st and then try it, if doesn't turn then there is a bug for sure. If it does then you need an F18 pilots feedback as to if it is how the aircraft behaves IRL.

Brun Posted June 25, 2018 Posted June 25, 2018 This might be explained by the relative lack of caster on the Hornet's nose wheel. Asus Z690 Hero | 12900K | 64GB G.Skill 6000 | 4090FE | Reverb G2 | VPC MongoosT-50CM2 + TM Grips | Winwing Orion2 Throttle | MFG Crosswind Pedals
NeilWillis Posted June 25, 2018 Posted June 25, 2018 I suspect there is no need for differential braking in an aircraft with NWS. What exactly is wrong with using the NWS in the first place? No rudder pedals?
Precog Posted June 25, 2018 Author Posted June 25, 2018 I suspect there is no need for differential braking in an aircraft with NWS. What exactly is wrong with using the NWS in the first place? No rudder pedals? If you want to increase the turn radius without engaging NSW HI a tap on the toe brakes helps with this. Pretty much the same with every GA aircraft I've flown. Just seems unrealistic but I'm no hornet pilot. Just putting it out there Check out my 'real world' video series [sIGPIC][/sIGPIC]
WindyTX Posted June 25, 2018 Posted June 25, 2018 Need an SME to comment the F3 had 60 degrees of authority in High and differential braking was not really a factor.

Pretty much the same with every GA aircraft I've flown. That would depend on the system that specific aircraft uses to turn the wheel. E.g. Cessna uses springs between the wheel and the yaw axis controls that allow you to push the pedals when stopped without turning the wheel. But when moving this means that you do not have direct control, your rudder inputs are delayed on the nose wheel because you are just compressing those springs. This also allows to tighten the turn with differential braking. There are also models (e.g. Cap 10 taildragger) with no control on the wheel, but with springs helping towards the center. Other aircraft use free wheel with no control and you mainly control direction with differential braking. (I think the Socata Rallye fits here but it could also have springs like the Cap 10) And then aircraft with direct connection from the pedals to the wheel (e.g. Tecnam). In these you cannot push the pedals when stopped because the weight of the engine does not allow you to turn the wheel. In these, differential braking has very little effect because the wheel cannot turn by itself. Now think of NWS as this last type, but with some kind of power steering for heavier aircraft. The nose wheel stays where you set it with the pedals and it should not turn by itself to either side when applying differential braking. [sIGPIC][/sIGPIC]
JaBoG32_Dirty Posted June 26, 2018 Posted June 26, 2018 (edited) I too think that the effect from differential braking is too little. In fact, I think that braking in general is very week in the Hornet. Might be plausible, because it's a carrier-based design, but feels VERY weak. NSW HI or not,... I'd expect to see a significant moment with differential braking. EDIT: I have actually tried this out in a plane with hydraulic NWS (please don't tell my employer!) and I think I should correct myself: As long as there is hydraulic pressure on the system the NWS will keep the aircraft surprisingly straight. At normal taxi speeds I was barely able to generate rates over 1°/sek. Wasn't able to test it with NWS off or w/o hyd pressure though. I guess the reason why people (including myself!) expect to see high turn rates with differential braking is because either... 1. ...they use it in planes w/o hydraulically controlled NWS 2. ...they use it to support NWS on wet surfaces when the nose wheel tends to skid easily. That's when differential braking can actually make a difference. Would love to hear what an actual Hornet pilot would say about this...
