class A aircraft additional take off procedure

#6. Reduced take-off thrust is prohibited when:

• Athe runway is wet.
• Bthe OAT is ISA + 10°C.
• Canti skid is unserviceable.
• Dit is dark

#1. With regard to a take-off from a wet runway, which of the following statements is correct?

• AScreen height cannot be reduced.
• BThe screen height can be lowered to reduce the mass penalties.
• CWhen the runway is wet, the V1 reduction is sufficient to maintain the same margins on the runway length
• DIn case of a thrust reverser inoperative, the wet runway performance information can still be used.

#2. For a take-off from a contaminated runway, which of the following statements is correct?

• ADry snow is not considered to affect the take-off performance.
• BA slush covered runway must be cleared before take-off, even if the performance data for contaminated runway is available.
• CThe performance data for take-off is determined in general by means of calculation, only a few values are verified by flight tests.
• DThe greater the depth of contamination at constant take-off mass, the more V1 has to be decreased to compensate for decreasing friction.
