| V1 wet concept is not longer applied. According JAR 25.113 new definitions are set for ASDR, TODR,TORR when the runway is wet/contaminated. The use of the reverse thrust is considered and Clearway lenght is not taken in account for take off calculations. "Fly the wing" is a very nice book BUT consider that it was first published around 1970 and 2º 1990. Certification rules are always changing, nowadays different criteria are used. Regards. |
