Ben's little list of ways to avoid PIFR disasters. Just a personal repo of rules of thumb
- Required descent rate = Groundspeed (kts) * 5 #for three degree descent
- Top of descent point = thousands to lose * 3 -- (for example, Need to get to 3000, currently at 10,000. 7,000 to loose, 7*3 = 21 = start your 3 degree descent at 21 miles out)
| Segment | Speed(kt) |
|---|---|
| Initial | 90-150 |
| Final | 70-100 |
| Circling (1.68 nm) | 100 |
| Missed | 110 |
| code | meaning |
|---|---|
| 1200 | VFR |
| 2000 | IFR in G on startup |
| 3000 | VFR in D, or IFR in E (rare) |
| 7600 | Com fail |
