Calculator for Flight:
The calculation of time, as well as commonly used in the calculation of the flight.In particular non-precision approach (VOR/DME, NDB/DME, LOC) for the descent profile calculation, making a more accurate non-precision approaches.

60进制计算器：主要用来累加飞行记录本中的飞行时间。
飞行计算器：提供60进制计算，以及飞行中常用的计算。 特别是非精密进近(VOR/DME,NDB/DME,LOC)的下降剖面计算，使得非精密进近更加准确。
