Regla 60 - 1

SUMMARY OF 60:1 RULES AND FORMULAS Jan 04
CLIMBS AND DESCENTS
The 60:1 Rule:
1° = 1 NM at 60 NM 1° = 100 FT at 1 NM

Climb and Descent Gradients:
Required gradient (FT/NM) = altitudeto lose (or gain) Pitch change = gradient (1° pitch change = 100 FT/NM)
distance to travel 100
VVI:
VVI = Gradient (or pitch X 100) X TAS in minutes
VVI for a3° glideslope = GS X 10 VVI for a 2.5° glideslope = GS X 10 - 100
2 2
Determine TAS and NM/MIN:
TAS = IMN X 600 TAS = IAS + (FL / 2)NM/MIN = IMN X 10 NM/MIN = TAS / 60

Steps to Determine Required Pitch and VVI (Winded Application). Mathematical steps:
Required gradient: Gradient = alt to lose
dist totravel NOTE: For practical
Required VVI with wind: VVI = gradient X groundspeed (NM/MIN) applications,
Required pitch change: Pitch change = required VVI each 60 KTSTAS ( in NM/MIN ) of wind will change
pitch 1°.

TURNS
Turn Radius (TR) Turn Diameter (TD) = 2 X TR

Distance to turn 90° using 30° of bank:
TR = NM/MIN -2 or TR = (IMN X 10) - 2
or or
TR = (NM/MIN) squared or TR = IMN squared X 10
10

Distance to turn 90° using SRTs and 1/2 SRTs:
SRT = .5% of TAS (orgroundspeed) 1/2 SRT = 1% of TAS (or groundspeed)

Bank for Rate Turns:
Bank for SRT = TAS + 7 Bank for 1/2 SRT = TAS + 7
10 20Lead Point for Radial to an Arc or 90° Intercept of an Arc:
Lead point in DME = Desired Arc + TR

Lead Point for Arc to Radial or 90° Intercept of a Radial:
Lead point (in degrees) = 60 X TR(in NM) or 60 X TR (in NM)
Arc DME

For Turns Less or More Than 90°, Use The Following: (These cover most situations):
