I wonder if someone could help me pin down what it is that I am not doing at take off that results in a red warning light (plus sound) until I leave the runway? I had thought that this was due to not arming the spoilers, but it still happens after correcting that oversight. I am starting the flight at the runway threshold with engines running, and the condition levers set to Flight mode.On a side note, after arming the spoilers before take off, they now work perfectly on landing when activating the reverse propellor pitch (the green light appears). Maybe nothing of consequence to most of you, but it gave me a thrill :(

Start and Gust lock off? (assuming yes as you can fly) Elevator trim in green band?Flaps set (9)?CAP and coaming panel showing no odd lights?

You have missed something on one of the checklists... it is hard to tell which. You will need to work through the various checklists until you find the appropriate switch you haven't set or system armed correctly... I would have guessed an out of trim warning perhaps, or flaps not set...When you press the take off configuration test button (on the FO panel, to the right of his displays from memory... might not be the exact location... I know I have to lean across to reach it...), do you get any warning sound and CAP annunciation?Andrew

Have you armed the spoliers?

I am starting from the runway threshold with the engines running, so I haven't looked at any check lists!! The flaps are set to 25 degrees at take off, and I have set the trim to a position which enables me to maintain a steady, gentle climb at roughly 70% torque without having to push or pull on the joystick.This warning isn't something that I am particularly concerned about. I am just curious :(

You might want to read my first post again :(

Your technique is interesting. Normal takeoff flaps is 9 and climb is 170 kts @ 100-98% RPM at max power or 10deg below max temp.You should clear the alarm before taking off, following the procedure recommended by Andrew. Once you can push the TOCWS and not get an alarm then you are good to go.

Dan,My technique makes flying the plane incredibly easy. My climbout speed is around 145 knots (with wheels still down), and it stays that way through left downwind, and final approach. All I have to do is vary the torque to control ascent and descent. This is my method when doing these short test flights. I will retract the undercarriage during flights between airports. Honest! :(

I think we've had a discussion very similar to this one before. I keep an open mind to the way you like to fly, and I have no intention of criticising you for it. However, given the vast differences between the way the airplane was MEANT to fly, and the way you ACTUALLY fly it, I'm not sure there is a way get rid of all the warnings generated by your techniques.I'm being completely genuine here, so please don't take it the wrong way, but if you really want to know why you're getting a TOCWS alert, then you need to do some reading in the manual and yes, the checklists too. To speed things along, the most likely causes for the alert you're seeing are: Trim not in the green band, Condition levers not in FLIGHT (use the key command to 100% if necessary), flaps not 9, and/or the parking brake is set.

No offence taken, mate. Like I said, I'm not too bothered about the warning, since it stops as soon as I become airborne. Based on the options you have stated, it is most likely to be caused by the trim not being set to the normal position for take off.I can live with that :(

Or flaps 25. Doesn't that adversely impact your initial climb?

Yep, thats your reason, you don't have the aircraft configured correctly (in the eyes of the engineers who designed it).

Any aircraft, whether real world or simulated, with even the most simple of instrumentation and systems, requires to be set up correctly for take off. Take off trim is for take off, not for climb out... flaps 25 for take off? That may be a setting that Boeing suggests for 737NG short field operations... but the PMDG JS41 has no data for flap 25 take offs, so how do you determine your V1 and Vr? Let me guess, you don't... :(Your warning comes from the TOCWS (what causes IT to warn is hard to tell though), because you are not configured for take off, as Jay so aptly wrote, as the British Aerospace engineers designed the plane to be for take off...AndrewPS: Engines running, on the threshold, does not imply that the before take off and take off checklists can be worked through... :(In the real world, I would say that a TOCWS warning would not be ignored...

It's a good job that we aren't talking about the real world then :( As for setting the flaps to 25 degrees for take off, that is simply my ignorance of aircraft operations. Being a novice at this flightsim lark, I had assumed that the flaps should automatically be set to maximum for take off! Not that it matters. The PMDG Jetstream rotates at around 110-115 knots (using a trim setting that I worked out by trial and error) with a 50 per cent fuel load and no passengers. As soon as I become airborne, I reduce the torque to roughly 70-75 per cent. This results in the aircraft performing a smooth climb out without the need to push or pull on the joystick. Certainly not "by the book", but that isn't why I purchased the aircraft. Stability at low speeds is what I look for in my virtual planes, and the PMDG Jetstream 4100 and Flight1 Citation Mustang (the only two planes that I will ever need) are superb in this department :(

You could have saved your self some work. There is a little booklet on the pilots side of the centre console which has all the information you need to get the 'correct' speeds for different weights and conditions.

Odd, as only the better simulations show the correct instability at low speeds that the real aircraft display.

You guys would have to do a search to see where this all started, so I'll save you the trouble...Chris (can I call you Chris?) isn't a realism guru like most PMDG customers. He's posted in the past, and a lot of people jumped in his chili about "doing it wrong". I was one of them.I've since come to realize that I don't need to be an ***hole just because he flies differently than I do. While I may not understand his motives for buying an ultra-realistic addon, it's really none of my business. I only hope that my participation here can help others better enjoy their J41 experience...whatever that may be.I humbly submit that we should all cut him some slack.
