Holding at BAG with a Thin Fuel Margin
You are the PIC of a Beechcraft Baron 58 on an IFR flight from Manila to Laoag, cruising at 10,000 ft. At 1418, Manila Control clears you: "BAG VOR, hold on the 090 radial, right turns, maintain 10,000, expect further clearance 1435." You are 15 nm west of BAG, tracking inbound on the 090 radial, heading 090. TAS is 180 kt and total fuel flow is 30 gph; you have 46 gal usable remaining. The wind at 10,000 ft is 360/30. Clark, your alternate, is 12 minutes from the hold; you plan a 45-minute reserve and a 15-minute contingency. Laoag is 400 ft overcast with 1,200 m visibility and an ILS; Clark is 1,500 ft broken with 8 km. At 1432 the controller says, "Expect further clearance 1450."
1. What holding entry will you make, and what outbound heading and leg timing will you use?

Because you are established inbound on the 090 radial, this is a direct entry: cross BAG, turn right to the outbound course of 270, and keep the pattern on the holding side (south).
Wind 360/30 is a right crosswind on the outbound leg-north is to the right when heading west. The crosswind is nearly the full 30 kt; the wind correction angle is about 10° (30/180 ≈ 0.17, arcsin ≈ 10°), so fly heading 280 to hold the 270 track. The along-track ground speed is 180 × cos 10° ≈ 177 kt, so the outbound leg is still timed at 1 minute (10,000 ft is below 14,000 ft).
After the outbound leg, turn right to the inbound course; the inbound crab is 10° left, heading 080, and you adjust the inbound leg to 1 minute by timing. Do not chase the heading indicator-use time, turn rate, and the GPS track.
2. Using the fuel figures, determine your fuel at the EFC and whether you should declare minimum fuel.

From 1418 to 1435 is 17 minutes. At 30 gph (0.5 gal/min) that burns 8.5 gal, leaving 37.5 gal at the EFC.
Fuel required to Clark: 12 min leg + 45 min reserve + 15 min contingency = 72 min = 36 gal. The margin is only 1.5 gal, or 3 minutes. You can hold only until about 1438 before you would land at Clark with less than your planned reserve.
Because you are committed to Clark and further delay would erode the reserve, declare minimum fuel now and request immediate clearance to leave the hold. Minimum fuel is an advisory to ATC, not an emergency declaration, but you must not accept a clearance that knowingly leaves less than the reserve.
3. The controller responds to your minimum-fuel call with "Expect further clearance 1450." What do you say and do?
Read the worked answer
Reply: "Unable to accept further clearance 1450 due to fuel; request immediate clearance to Clark." At 1432 you have 40 gal; 36 gal is already committed to Clark with reserve, so only 4 gal-about 8 minutes-is available for holding, i.e., until roughly 1440. You cannot accept 1450.
If ATC cannot release you immediately, declare minimum fuel; if the delay continues to the point where safety is affected, declare an emergency and request priority. Ask for the shortest routing, and consider a lower altitude only if it reduces burn without adding excessive time.
Do not let the controller's plan override your fuel math; the PIC owns the fuel decision. If Clark's weather were to fall below alternate minima, you would need to divert earlier, not hold longer.
