You plan a day trip from NZCH to NZWS (Westport) in your Texan. It has a TAS of 315kt and a fuel consumption of 30GHP. You load on 110 gallons and check your flight plan which states a total ditance of 132nm and a tailwind of 18kt from NZWS to NZCH. What is PNR and ETP distance?
PNR = 700nm ETP = 500nm
PNR = 50nm ETP = 70nm
PNR = 70nm ETP = 50nm
PNR = 500nm ETP = 70nm
You plan a night-time flight from NZCH to NZHK (Hokitika) which is 102nm total distance. Your TAS is 105kt and you have a wind of +15kt. If you load up 100L of fuel and your fuel burn is 36L an hour, what is PNR distance and ETP time?
PNR = 0.84 ETP = 44nm
PNR = 100nm ETP = 22 minutes
PNR = 50 minutes ETP = 44nm
PNR = 60nm ETP = 25 minutes
