No problems here Howard ;)TEA UL995 PEPAG UN851 ELMUR UL613 SANDY/N0425F240 N57 WELIN T420 TNTYou have to be in the Lower @SANDY

One general question, what does "/N0425" mean?My guess is GS or IAS.Regards,Marius

Hi Marius,IASTherefore is gives also M (Mach) , K (Kilometer)

Thanks Samy,will re-crunch.Howard

Samy,The correction you made to the flight plan is indeed correct. :-) But, "N" is expressed in TAS/True airspeed :-) IAS/Indicated airspeed is the airspeed indicated on the airspeed indicator. Can you now imagine what 425 kt IAS is? :-) Also see http://www.ivao.aero/training/tutorials/fl...flightplans.htm"Insert the first cruising speed as the True Airspeed for the first or whole portion of the flight, in terms of :...Knots , expressed as N, followed by 4 figures ( e.g. N0220 )"Or to put in another way, http://www.flyingineurope.be/Flightplan.htm"Cruising speed
