Non-SP GIV Landing Distance Using Twin-Engine
Reverse Thrust Only (No Braking) OM 07-01-80
The table on the following page shows landing distances when using
reverse thrust only to bring the aircraft to a stop. The distances shown
below assume reverse thrust is used to 20 knots with stowage by 10
knots.
Conditions:
• Two Engine Reverse Thrust Only
• No Slope
• No Wind
• Standard Day Temperature
• AUTO Ground Spoilers
• No Runway Surface Contamination Accumulation
• Full Reverse Thrust To 20 Knots
• Stowage By 10 Knots
• Minimal Braking Below 10 Knots
• Flaps 39°
NOTE: Flight Manual procedures recommend that cancellation of thrust
reversers be initiated by 70 knots so as to be completely cancelled by the
time normal taxi speed is achieved. If landing runway conditions will result in
compromised braking performance, this table may be used to provide
additional information for pilot judgement.

Non-SP GIV Aircraft Classification Number (ACN)
GIV-GER-481
Aircraft Classification Number (ACN) is a number expressing the
relative effect of an aircraft on a pavement for a specified subgrade
category. ACN values are calculated for both flexible and rigid
pavement. If the aircraft gross weight and runway subgrade strength
are known, the ACN value can be determined from the charts on the
following pages.
Pavement Classification Number (PCN) is a number expressing the
bearing strength of a pavement for unrestricted operations. It is
reported in the Jeppesen charts in a format such as 24/F/C/Y/T,
where:
24 is the PCN
F is the type of pavement, where:
R = Rigid
F = Flexible
C is the subgrade strength, where:
D = Ultra Low
C = Low
B = Medium
A = High
Y is the tire pressure, where:
W = High, no pressure limit
X = Medium, limited to 217 psi
Y = Low, limited to 145 psi
Z = Very Low, limited to 73 psi
T is the PCN classification, where:
T = Technical Evaluation
U = Aircraft Experience
Non-SP GIV ACN values are:
Flexible Pavement Rigid Pavement
Subgrade D 21 23
Subgrade C 22 24
Subgrade B 23 25
Subgrade A 24 26
(Based on 73,600 lb gross weight and 175 psi tire pressure.)
ACN values must be less than or equal to the airport PCN for
unrestricted use. ACN input variables are gross weight, percent load
on main wheels, wheel spacing and maximum tire pressure.
