Last week, we ran a quiz on the LDA/DME into Eagle County in Colorado's Rocky Mountains. Here's an approach without the terrain considerations - how well can you fly it?

Boldmethod

For this approach, you're flying a Cessna 172 - a Category A aircraft.

1) What's the minimum equipment you need to fly this approach?

Awesome! The approach only requires a VOR - but a DME gets you lower minimums.

Incorrect! The approach only requires a VOR - but a DME gets you lower minimums. And DR approaches just seem like a really bad idea.

2) You've been cleared via V2 to AXN and you're at 13,000' 42 NM away from AXN. ATC clears: "Cirrus Three Bravo Delta, cleared for the approach into Alexandria, frequency change approved." What's the lowest you can descend right now?

Awesome! You can't descend to the MOCA until you're within 22NM of AXN.

Incorrect. You can descend because you've been cleared for the approach, and you're on a published route segment. You can't descend to the MOCA (3000') until you're within 22NM of AXN.
3) You decide to execute the VOR RWY 22 because the ILS is out-of-service and you don't have GPS. ASOS reports the winds out of 320 at 28 knots, with ceilings varying from 800 to 1000 feet. Can you plan to circle to land on Runway 31?

Awesome! The approach allows you to circle-to-land.

Incorrect. This approach allows you to circle-to-land.

4) You want to join the approach at the earliest opportunity. What's your first opportunity to join the approach?

Awesome! The arc intersects V2 and is your earliest initial approach fix.

Incorrect. The arc intersects V2 and is your earliest initial approach fix.

5) You elect to fly the arc, but as you near R-044, you're still at 11,000'. How can you gain more time to lose altitude?

Awesome! You need to call ATC and request holding.

Incorrect. The arc prohibits a procedure turn, so you need to call ATC and request holding.

7) Your DME fails after you cross the AXN VOR. What's the lowest altitude you can descend to on a circle-to-land approach?

Awesome! The circle-to-land MDA without DME is 1980'.

Incorrect. The circle-to-land MDA without DME is 1980'.
8) Your DME's still out and you're flying the approach at 90 knots. ASOS reports the winds out of 320 at 28 knots. How will you recognize the missed approach point?

Awesome! You'll need to time your leg to the MAP. Considering your airspeed and the wind, your groundspeed is about 90 knots and it will take you 5:36.

Incorrect. You'll need to time your leg to the MAP. Considering your airspeed and the wind, your groundspeed is about 90 knots and it will take you 5:36.
