| If your answer is... | Likely mistake | |-----------------------------|------------------------------------| | Exactly double/half correct | Misplaced decimal (use 10 index) | | Off by 10° on wind correction | Read left vs right side wrong | | Slightly off on TAS | Used indicated instead of calibrated, or forgot pressure altitude |
Cross-verify with these known pairs:
Exercise 3.1
E6B method:
Align OAT (+30°C) with pressure altitude (4,000 ft) in density altitude window. Read DA directly. e6b flight computer exercises verified
Verified answer:
DA = 6,500 ft
Exercise 3.2
Verified:
DA ≈ 8,200 ft
Exercise 6.1 (Full planning)
Step 1 – Wind correction (E6B):
Wind from north (360°). TC 090° → crosswind from left.
WCA = 9° right → TH = 099°.
GS = 111 kt.
Step 2 – Time:
150 NM at 111 kt → 81 minutes (1 hr 21 min). | If your answer is
Step 3 – Fuel:
81 min at 8.5 GPH → (81/60)*8.5 = 11.5 gallons.
Verified:
TH = 099°, GS = 111 kt, Time = 1:21, Fuel = 11.5 gal
