Run-up procedure during single taxiing?
Thank you for your posts.
I have some questions related to the single engine taxiing and the run-up engine procedure especially in congested airports.
-It seems the use of engine anti-ice during taxiing is not very efficient in certain icing situations like freezing drizzle. I am wondering if it is efficient why there is a need for run-up engine procedure during icing conditions?
-Is the fan and the nose spinner anti-iced (in the RECENT engines) when engine anti-ice is used or just the engine inlet is anti-iced?
All I know that in the JT8D the IGVs(inlet guide vanes) and the nose spinner are anti-iced (old engines)
- Is it possible to make run-up procedure while performing single or reduced engines taxiing?(the dead engine may accumulate more ice or may be pilots will alternate the use of engine during such taxiing?)
-Run-up engine of 70% N1 or more (even for 30 seconds or less) may present a hazard (jet blast) for the airplanes behind or even ground equipments?
Feedback appreciated. Thank you.
Best regards.
