For the approach at 5T6 we will conduct the one approach available- the RNAV (GPS) 10.
This is a mountainous area and even at 9000’ we will most likely be below radar coverage. We arrive at 5T6, then
must fly the procedure turn to SUSIQ- a distance of 17 miles. Then we must fly the procedure turn (5 miles out), then
turn inbound (another 5 miles). Reaching SUSIQ we have another 17 mile inbound- so far we have 17+17+5+5=44
miles of flight that was not figured into our fuel planning.
Upon reaching the missed approach point we don’t see the runway and execute the missed. Again, this is non-radar
so we anticipate the published missed- which means we head back out to SUSIQ and do the 5 mile holding pattern
once again. We will assume (again for simplicity), that upon reaching SUSIQ we only do one turn in hold, then head
back to 5T6, then direct KELP. The time from 5T6 was included in our planning, but the missed approach and hold
were not- so we need to add another 44 miles to our route for a total of 88 miles up to this point that was not factored
into our fuel planning. But wait. There’s more.
We still need to get into KELP. We planned on the ILS 22-
El Paso does have an approach control so here we will assume a short vector to final- we’ll say 5 miles out which puts
us 1.5 miles outside the FAF. So 5 miles out, then 5 miles back in. That is another 10 miles not factored into our flight-
88+10=98 miles of flight not factored in. Now let’s do the math to see how long this will take at 120 knots. 98 miles at
120 knots equals 49 minutes of flight- which means we will probably run out of fuel during our vectors for the ILS at El
How do we avoid this?
1. A more conservative approach would be to plan on having enough fuel to fly to your destination, fly the most likely
approach, then 45 minutes of fuel.
2. If an alternate is required plan on the most likely approach and published missed at your destination; one turn in
hold; fly to your alternate (along the most likely route from your missed approach hold); execute the most likely
approach at your alternate; then fly an additional 45 minutes at cruise.
