As above
Best rate of climb speed C208 EX
108 KIAS
Decision points and respective distances
Less than 800m - 40 KIAS OR 1/3 TODA 800m - 1200m - Vlift off - 10 KIAS 1200 - 1500m - Vlift off 1500m - 2000m - 50’ AGL < 2000m - 200’ AGL
If Ng is observed slower than normal. Abort start, possible weak battery
As above
Hung start
Ng stagnate at 35-40%
Aborted start reasons
- No light off within 10 seconds
- Poor cranking power (Ng stagnate at 35-40%)
- Starter accelerates Ng rapidly above 20% (gear train decouple)
- Rapid acceleration beyond 35% (start on secondary nozzles)
- Rapid ITT increase toward 1090°
- Compressor stall
- Starter on after 46%
Aborted start sequences
- Starter switch off
- FCL cut off
- If ITT excessive or requires assistance to reduce thence motor
