(d)
Make all turns at a slow taxi speed to prevent tire skids.
(e)
When an outboard engine is used to help make a turn, use only the minimum power possible.
(f)
Do not let the airplane stop during a turn.
(g)
Do not use the brakes to help during a turn.
NOTE: See the paragraph on Airplane taxi in bad weather
____
conditions about differential braking.
1) Decrease the speed of the airplane with the brakes when it is necessary, before the turn is started.
2) Make a minimum radius turn with maximum nose wheel steering, and the engine thrust only.
3) When you use the brakes during a turn, the main and nose landing gear tires will be scrubbed.
(h)
When it is possible, complete the taxi in a straight line roll for a minimum of 12 feet. This will remove the torsional stresses in the landing gear components, and in the tires.
Airplane taxi in bad weather conditions.
(a)
You must know the conditions of the taxi surface, and the taxi speeds when you taxi in bad weather conditions.
(b)
If the taxi surface has snow, slush, or ice on it, the anti-ice system can be used.

(c)
Taxi the airplane with the flaps up.
(d)
Use the differential engine thrust when you taxi the airplane on a slick surface at decreased speeds. This will help to keep airplane movement through a turn.
(e)
A light differential braking can have more of an effect than nose wheel steering, on very slick surfaces.
E. Airplane Characteristics (Figs. 201, 202, 203, 204)
(1)
The minimum turn radius that the airplane can make is shown in Figure 201. The wingtips and the horizontal stabilizer move in larger arcs during a turn than the nose of the airplane. Thus, monitor these areas of the airplane carefully for clearance with buildings, equipment, and other airplanes.
(2)
The basic factors that can change the geometry of a turn are as follows:
(a)
The nose wheel steering angle
(b)
The engine power position
(c)
The center of gravity location on the airplane
(d)
The airplane gross weight
(e)
The taxi surface conditions
(f)
The airplane ground speed
(g)
The differential braking that you use.
(3)
When you operate jet engine airplanes, you must follow all precautions. This is neccessary to prevent injury to persons, or damage to buildings, equipment, or other airplanes.
(a)
Refer to Fig. 202 to find the dangerous areas at engine idle, and at the engine breakaway thrust.
(b)
All persons must keep away from the two engine inlet and exhaust areas. Hot, high velocity gases come out of the exhaust nozzles of the engine. The velocity of the engine fan air, specially at high thrust positions, is sufficient to cause injury or death to persons.
(c)
When the thrust reverser is in the reverse position, the high velocity fan air will come out and move forward. When this occurs, the hot, high velocity engine exhaust gases will continue to come out rearwards.
(4)
To find the angles of view from the flight compartment, for a person in the left seat, refer to Fig. 204. This is when the left seat is correctly adjusted.
