Mental Maths for pilot
Sacado de unas guias de estudio (Cheet sheets) del T38. Sabiendo que aqui hay gente que de esto entiende "un huevo" ¿Opiniones? ¿Son aplicables a nuestros pájaros?
60 ¸ DME = Radials / NM
(i.e. 20 DME Arc = 3 Radials/nm)
90º Turn Radius
10% of KCAS (Low Altitude)
IMN – 2 (High Altitude)
(i.e. 300 KCAS = 3nm Turn Radius at Low Altitude)(i.e. .8 IMN = 6nm Turn Radius at High Altitude)
Arc to Radial Lead Point Radials/NM x Turn Radius
(i.e. 20 DME Arc = 3 Radials/NM * 6nm Turn Radius = 18º Radial Lead Point)
Lead Point Fractions
60º Turn = ½
45º Turn = 1/3
30º Turn = 1/6
(i.e. 6nm 90º Turn Radius = 1nm 30º Turn Radius)
Descent Gradient Altitude to Lose ¸ Distance = % of 10º
(i.e. 8,000ft ¸ 32nm = 1/4 » 2.5º Nose Low)
Crosswind Component (Clock Method)
15º Off = ¼ Past
30º Off = ½ Past
45º Off = ¾ Past
(i.e. 310º Heading, Winds 265/20, Crosswind = ¾ * 20 = 15kts)
Drift Correction Crosswind ¸ IMN = º of Correction
(i.e. 15kts ¸ .8 IMN » 2º Correction)
Mach Calculation KCAS ¸ 60 = NM/Min = IMN
(i.e. 300 KCAS = 5 NM/Min = .5 IMN)
VVI Calculation
Use Groundspeed Instead of IMN for Wind Correction
IMN * Pitch = VVI(i.e. 180kts = .4 IMN * 2º Nose Low = 1,000fpm)
Procedure Turns
Travel Outbound How Far to Remain Within Specified Distance:
80/260 45/180
3 * Turn Radius (3 * Turn Radius) + 2
(i.e. Turn Radius = 4nm, Travel 12nm Outbound Before Beginning 80/260)
Holding Turn
Displacement From Inbound Course
Turn Radius * Radials/NM * 2
(i.e. 2.5nm Turn Radius at 30 DME = 10º Radial Displacement)
Hydroplaning Speed Are You Freakin’ Kidding Me
(FYI A/S = 9 * Á–Tire Pressure)
Perdon por el formato, pero es copiado de un word y esto no hace lo que yo quiero exactamente
Súbelo a algún sitio y nos descargamos el word.
esto merece una aplicación para tener a mano...la hay? hay que hacerla?
