It is important to realize that any calculated performance may be different from what is realized live. What I do is skip the payload page of TOPCAT and go straight to the takeoff page, update weather for the airport, select runway and enter my takeoff weight. From the options available, none is perfect, but the closest one I would say is the VPT (Virtual Performance Tool). This is the FMC calculates at a very basic level without consideration to any obstacles, climb limits, etc. your OFP. Contact us for more information. Lift-off Speed, VLOF. increased situational awareness. With an extensive database on Boeing 737 Next Generation series performance, TOPER allows you to accurately calculate the highest safe assumed temperature to complete a reduced power take-off and the appropriate take-off speeds.

Takeoff Power - The first percentage is your throttle amount. De-rate and assumed temperature is done through the THRUST LIM page, and the V-Speeds done through the TAKEOFF REF page. Dispatch with a broken plane by Designed for Android.No warranty is given! Hard to say. Just tried right now. Developing a full takeoff performance calculator, including flex temperature reduced thrust performance, is a bit problematic at the moment because Airbus does not provide generalized takeoff performance data like in the past. ?, yep) :wink: It is not necessarily overwhelming because data has to be entered, but visually I mean. Please do not upload this file anywhere else! Disclaimer: " A310 Takeoff Performance Calculator " is a personal software of the developer. Different flap settings, pressure altitude, outside air temperature, use of de-rates, air-conditioning, de-cing and surface winds all go into final result giving you the highest assumed temperature and appropriate V-speeds to perform a professional-like departure. Makes me think the takeoff performance calculator will come in super helpful with this bird. Tom Allensworth, No one can excel in everything. | OurChurchPress.com. However, retro-style rough estimations can be had for simulator use via documents such as the FAA's Airplane Characteristics for Airport Planning, which are free PDFs for downloading from the FAA. To reach your goal of the most realistic preflight and operation of a Boeing 737NG, you need to compute the assumed temperature with its respective de-rated thrust power. Clicking the appropriate category toggles the choices available . (Assuming no more than 2% runway gradient) Until now I was using the assumed temperature (65C) and flap settings (5) from the tutorial flight Maldives-Dubai for all my flights! Your message has been Disclaimer: it's a very simple program, which provides you with the maximum engine derate for a given situation (Runway lenght, density altitude, TOW, flap setting) If you're looking for Vspeeds, Flap retractation speeds and all other goodies that come with takeoff performance calculations, this will disappoint you.
