flight planning Flashcards
what is Vs0
stalling speed with flaps down and gear down
the lowest speed at which load factor=1 is also known as
clean stalling speed (Vs1)
what is Va
maximum manoeuvring speed (105) kts
why is Va not marked on the ASI
because it changes with weight
what will happen to the aircraft before structural loads are exceeded
it will stall
what is the normal operating speed (Vno) of the 172
129 kts
what is the never exceed speed of the 172
163 kts
what is Vb
maximum turbulence penetration speeds
why are vertical gusts so dangerous
can cause a loss in control
what is Vle
the max speed at which landing gear can be extended
what is Vlo
the maximum speed at which the landing gear can be operated (always slower than Vle)
what is the equation for ISA temp
15- (2 x height)
what is the equation for working out ISA deviation
actual temperature - ISA temperature
what is the equation for density height
DH= PH + ((ISA X DEVIATION) X 120)
what defines ambient conditions
conditions in the 15 minutes preceding take-off
