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?

 

Radials/NM

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
