Flight-Deck Calculators
The four bits of mental math every sim pilot needs — done for you, so you can keep flying.
Top of Descent
When should you start down? Pure geometry: your altitude to lose and the descent gradient. 3° is the standard airline path — change it if your arrival needs something steeper or shallower.
Required Vertical Speed
Already past the ideal point? Given the distance you have left, how steep does the descent need to be? Add your groundspeed if you also want the answer in ft/min for the V/S window.
Crosswind Components
Runway plus wind — how much is across, how much is on the nose?
A320 V-Speeds Helper (simplified)
Ballpark takeoff speeds for CONF 1+F, near sea level. Real-world performance depends on runway, temperature, and more — these get your sim flight airborne sensibly. Your aircraft's MCDU/EFB numbers always win.
Enter these on the MCDU PERF TAKEOFF page. Typical A320ceo max takeoff weight is 78 t.
The 3-to-1 rule, the clock-face crosswind trick, and how airline pilots actually estimate this stuff in their heads — all explained in the book.
