This document are some notes i made for the ATPL subject Principles of Flight. It is not a complete summary but just some information i found important during the lessons. I made the notes for my ATPL theory, i passed all 13 subjects with an average of 93%.

-Cl (coefficient), Cosinus = For LIFT
-Ts (Thrust), Sinus = for THRUST
-Rt (RadioTelephony) = Tangens = for turn RADIUS
!De 3 belangrijkste formules!
-L= W x cos γ (:=climb, x=descent)
-T= D + W sin γ (+=climb, -=descent)
-R= (TAS2 : (g x tan Φ)) (Let op: TAS = m/s)
For increase in lift during a turn
-1 : cos bankangle = loadfactor. For example: 1 : cos 60 = 2 . So the lift is doubled.
Climb gradient
-Climb gradient = Tan γ x 100% (100 m horizontally -> ….. m vertically)
γ = Climb angle
Φ = Bank

-Vsnew/Vsold = √(𝐶𝐿𝑜𝑙𝑑/𝐶𝐿𝑛𝑒𝑤)
-Mach = TAS/LSS (Local speed of sound) → LSS = 38,95 x √𝑂𝐴𝑇
- Lift = CL½ ρV 2 S
- Drag = Cd½ ρV 2 S
-Increase in stall speed in turn = 1 ÷ √𝑐𝑜𝑠 𝜙
-New stall speed = Vstall x √n
