Risk Management Handbook (FAA-H-8083-2A)that there may be an issue with fog and low ceilings at Santa Rosa due to the coastal marine layer. This may dissipate by noon, but it is not yet possible to predict. 12160 Tricia starts by calculating the allowable fuel load. With an empty weight of 1,903 pounds and a maximum allowable gross weight of 2,740 pounds, the useful load works out to 837 pounds. Tricia weighs 130 pounds, the Smiths together weigh 340 pounds. Together Tricia and the Smiths have 120 pounds of baggage. Tricia also has an electronic flight bag (EFB) and pilot gear totaling seven pounds. This leaves 240 pounds for fuel, which is 40 gallons. The airplane currently has 25 gallons on board. 12161 There is a serious (yellow) hazard if making a gross weight takeoff from the Animas Air Park (00C). She decides to ask the Smiths to take a taxi to the Durango – La Plata County Airport (KDRO), which is about a ten-mile ride for them and a 7-nautical mile flight for her. It has a 9,200-foot runway. She can add 18 gallons of fuel before the short flight to Durango – La Plata County Airport, and can depart from there at gross weight, which includes 40 gallons of fuel. She plans to make one additional fuel stop. 12162 After a thorough analysis and weather briefing, she elects to fly a southern route to avoid hazardous weather. She plans to refuel at the Barstow-Daggett, CA airport (KDAG). The 490 NM route from Durango – La Plata County Airport uses the Winslow, AZ (INW) VOR as a waypoint and should take 3 hours and 15 minutes. She will have 4 hours and 30 minutes endurance. From there, she will fly to Santa Rosa using the Palmdale, CA (PMD) VOR as a waypoint. This route is 390 NM and should take 2 hours 45 minutes with a 4 hour and 30 minute endurance. [Figure 5-1] 12163 Figure 5-1. Modified route. 12164 The total distance along this route is 880 NM, versus the straight-line distance of 711 NM. The additional 169 NM adds about 1 hour and 15 minutes to the total flight time. 12165 She mitigated the aircraft and environmental risks using this plan. She should also deal with the external pressure risks associated with leaving a day early, given the need for the Smiths to forgo the Monday festivities in Durango. An early departure also reduces the external pressures associated with making the Tuesday afternoon meetings on time. Tricia needs to explain the risk analysis to the Smiths and show them why a Monday departure is necessary. 12166 She has concerns related to her instrument proficiency. To compensate, she decides to add 500 feet to her personal minimums for an instrument approach into Santa Rosa. This might require landing at a suitable alternate airport. With the predicted fuel load, she calculates that Sacramento Executive Airport (KSAC), 62 NM from KSTS and well inland, would be a good alternate. 12167 She also considers pilot aeromedical risks. She will consume no alcohol, have an early dinner, and go to bed early. She also increases her intake of water. These actions should help avoid dehydration. 12168 Having addressed all the previously identified risks, she completes the FRAT for the proposed trip, listing all of her mitigations. The completed FRAT in Figure 5-2 shows all the risks mitigated to medium or low levels. For illustrative purposes, the
