Final answer:
To determine the total distance required to land over a 50ft obstacle, consider the pressure altitude, headwind, temperature, and type of runway surface. Calculate True Airspeed (TAS) using pressure altitude and temperature, then calculate Indicated Airspeed (IAS) and Groundspeed (GS) by considering the headwind. Finally, use appropriate tables or formulas to calculate the landing distance based on the runway surface type.
Step-by-step explanation:
To determine the total distance required to land over a 50ft obstacle, we need to consider the pressure altitude, headwind, temperature, and type of runway surface. Given that the pressure altitude is 5000ft and the temperature is 41F, we can use the pressure altitude and temperature to find the True Airspeed (TAS) using a flight computer or reference chart.
Once we have the TAS, we can calculate the Indicated Airspeed (IAS) by applying appropriate corrections for altitude and temperature. Using the IAS, we can then determine the Groundspeed (GS) by subtracting the headwind component from the TAS. Finally, we can calculate the distance required to land over the 50ft obstacle by using appropriate tables or formulas that relate groundspeed to landing distance for the given runway surface type.
