The external model remains one of the most accurate for FSX. Key highlights include:
Here is the killer feature: Frame rates. The iFly 737 is famously lightweight. Where the PMDG 737 could drop your FPS from 30 to 12 at a complex airport like FSDT JFK V2, the iFly would only dip to 24. For FSX users still flying on Intel Core 2 Duo or early i5 processors, this was a lifesaver.
In the world of FSX, adding a heavy, complex airliner often turns your simulator into a slideshow. This is where the iFly 737 has always shined.
While competitors like the PMDG 737 NGX are famous for their depth, they are notoriously heavy on frame rates. The iFly 737, however, has long been considered the "hot" choice for simmer pilots who want advanced systems without melting their CPUs.
Why it runs smooth:
If your definition of "hot" is a smooth 30+ FPS while sitting at the end of the runway at a dense addon airport like Heathrow or JFK, the iFly 737 is your answer.
Below is a short, clear text explaining how to hot-start the iFly 737 in Microsoft Flight Simulator X (FSX). It assumes the aircraft is powered by ground electrical and APU/DC power is available for systems but engines are shut down.
If you want a full checklist formatted for printing or a cold-and-dark start procedure, tell me which variant (NGX, CEO) and whether you use APU or external air — I’ll produce a step-by-step checklist.
To provide a balanced report, the following drawbacks must be noted:
