        Then it’s time to T/O with a lighter load (less fuel for instance), and do some AAR.
        Is that possible with the Harrier in BMS ?

          I’ve been wondering about this as well.
          Even with a proper takeoff procedure of nozzles at 30- flaps short takeoff - afterburner - once airborne nozzles at 60-70; she seems to need a skiramp.
          Since the appropriate carrier is not yet ready for operations, the only workaround it seems is to modify files which would allow using catapult. There was a topic somewhere on the forums about similar issue with super hornet and you can basically hack it in turning any aircraft into carrier capable.
          Would be curious to know if there is a legitimate way of taking off now though.

            Well, in BMS 4.33 harrier could start with a catapult, and here it doesn’t work. And in the Carrier Ops manual it says that the harrier is full-function for operations from an aircraft carrier, just like the f-18 hornet

              AV-8 Harrier are not made to be catapulted. If if was the case in 4.33, then it was a bug, if it is no longer the case in 4.34 … good. If it is still possible in 4.34, then we have to fix it.

                Harrier cannot irl take off from a catapult, it has no launch bar and is not designed for
                The manual ain’t lying, it can take off from the carrier, but in the way it is designed for, just as Flow explained it to you

                There are different technique according to launch weight, you need to document yourself with the proper procedures and then try them in the sim.

                  @Flow32:

                  Is that possible with the Harrier in BMS ?

                  Yes. I several times took off from a carrier with Code with a light fuel load, then fueled up before pushing.

                  I’m waiting for the WARN bug fix before flying the AV8B+ again in 4.34. And the Wasp!

                    From what I tested, in BMS 4.34 Harrier is only suitable for land airports, because starting with a weapon from the short LHD Wasp on peno is not possible. With great luck it can be done with the CV-71.

                      The problem is that you need a Harrier throttle console with a working STO Stop. An actual Harrier has a movable Stop that allows you to quickly and accurately slam the nozzle lever to a predetermined position - takeoff technique is to start with nozzles aft, full throttle, and slam the nozzles to the Stop (setting determined by takeoff gross weight, runway available, and temperature of the day) at a predetermined airspeed (based on the same). Without some sort of implementation of the STO Stop (in software or hardware) you’ll never be able to do an STO properly.

                      The STO Stop is the little knob to the inboard side (up) of the Nozzle lever - shown here:

                        Don’t screw me in, I tried this maneuver. Even if it’s full speed, it will fall after using this nozzle trick. As if you were writing, I would have started vertically.

                          Remember - ALL of this is gross weight dependent. A RL Harrier can’t VTO (or hover) with a full combat load. So it sounds like you’re just plain over gross for what you’re trying to do.

                            Stevie, you don’t understand me. The point is to start with the permissible mass at all. Not vertically, but from the short LHD run down, as Flow showed.

                              What is your T/O weight ?
                              So we can reproduce it.

                                Wait a minute and I’ll make a video , Maximum permissible weight

                                  Well if it’s the max for the airframe, there is your answer…

                                    However, it succeeded, but on LHD, it’s probably not possible. And this is not the maximum weight.

                                      The maximum weight you are refering to is the maximum T/O weight for that airframe.
                                      When you T/O from a carrier in STO mode, it will be way less, and will also depend a lot on tempareture and other factors.
                                      As for the landing, I guess you are also way above maximum landing weight on top of using the arresting gear of a carrier with the Harrier, which it is not intended for.

                                        Yes - Max Permissible T/O Gross has nothing to do with what you can actually take off with for the conditions of the day. If you were using the actual pubs, you’d calculate a max allowable GWT for the field length and conditions of the day which will likely be far less than max allowable.
