(For a rough estimate V1 is about 10 kts less than V2 and Vr is about 2 kts more Where do I find the value for CG%, because at this point the FMC is at the N1 page and the automatic CG and trim calculations only happen once you proceed to the takeoff page? The yaw damper on a 737 is turned or before takeoff. We may share certain information about our users with our advertising and analytics partners. Vref for flaps 40 for 50t is Vref 30 - 4 = 130kts. A/C to my understanding means aircraft, yet it doesn't make any sense to me in this context. Vr for 53.5t is 134+2=136. The support from Nikola is reactive. The string at the bottom "2 HW / R4 XW KT" seems to represent the formula used for the calculations, is that assumption correct? - Landing-Enroute: added MACG for B737-800 (airport elevation till >10000ft) Example: Actual weight. is 40t. You need to be a member in order to leave a comment. Next printed weight in QRH is 50t which is 2 steps away from ref weight. When you do the filed turns to FL340-CI20. To make the above calculation easy, like John's method we need to remember only 40t 17kts. First very simple ones. It's up to the developers to create an accurate addon not the other way around. I've been using the new Virtual Performance Tool website: Ill take that endorsement as gospel and check this out. It Does not include recommended take off power setting as well as what it thinks the optimum flaps should be. Similarly if the weight is lower than 60t we subtract one more flap that is Fuel Planner You should be getting temperatures that are less than 70deg. V2 for 50t: 50-5=45-(1+2)=42 ie 142. Do this by clicking the username pull-down at the top right, then selecting "User Settings." lengthy. Copyright 2023 NJsoft, Nikola Jovanovic. This is calculated on a case basis for each takeoff according to conditions (runway length, OAT, wind . I do own TOPCAT and PFPX 2 but no longer have P3D installed and I guess these require the host sim to be present. I didn't fly much on Zibo, so hope someone else could tell. V2 for 53.5t will be 142+5=147kts. TOPER Activator v 1.1.0.18, NJsoft(c)2016 The key I used on the software does not work with the Toper Web version. TOPER uses real-life takeoff performance data for all calculations ensuring high level of realism for your flight simulation experience. Assumed temperature takeoff is supported. Add a Comment. It's giving me the same V speeds as the FMS calculates +/- 2 knots. Vref for 40t for flaps 30 is 40 x 3 = 120 -1 = 119kts. Tom Allensworth, I forgot to circle ATM as my understanding (Air Traffic Management) doesn't make any sense. Now you can finally use that "TAKEOFF REF" page on your 737 CDU like a pro! I understand the landing performance calculator provided by the AviTab just fine, but the takeoff one gives me a bit of a headache. Advanced Flight Simulation Fuel Planning. Any ideas? The FMC is at the N1 limit page at this stage and the CG and trim is only calculated once you proceed to the takeoff page. The only only aircraft it gives me a different Flex Temp is the 600.

Briefly SEL is used to make the engine operate under the assumption that OAT temperature is higher than actually is during takeoff. 3.00 euro. I leave to the pilot whether he would like In this video we are diving into the systems that play a role during a takeoff in the 737 NG and the Classic. The takeoff section will be worked on very soon. For some aircrafts fixed derate (TO1, TO2) is available. Onboard Performance Tool provides self-planning capability through fast and precise calculations that save time by correcting for pressure variation, runway conditions and engine bleeds. For this we maintain the same correction as if we can not ramabuntzi 3 yr. ago. The use of assumed temperature not only brings you closer to real life aircraft operation, but consider a scenario where you have a light load and a very long runway: using the maximum allowed thrust would accelerate your aircraft so quickly that it would make your airplane take-off like a rocket and you will most likely accelerate way beyond the V2+15 knots in the initial climb. V2 for 45t: 45-5=40-5=35 ie 135 which is only 1 kt less than QRH V2. In principle, we do not share every extension. when weights are more than 50t. For 737-800 V2 is approximately take-off weight - 20. is then multiplied by 3. Keep in mind this software is prohibited to use on real world aviation -------------------------------------------------------------------- 120+15 = 135 - 1 = 134kts.
