Question 1

Point of equal time or critical point formula

Answer 1

Dpet=(Dtotal X GSreturn) / (GSreturn + GScontinue)

Tpet=Dpet/GScruise

Question 2

Point of no return calculation

Answer 2

F-fuel endurance in hours
Dpnr=(F X GSreturn X GSoutbound) / (GSreturn + GSoutbound)
Tpnr= Dpnr/GSoutbound
