Does a jet aircraft need to constantly adjust nose down to follow the curvature of the earth?

Planet Earth seen from Space
 
Dear Capt Lim;

I have limited flying experience (two introductory flight lessons in a Cessna and several commercial flights, including some Transatlantic trips), so please excuse my ignorance.

I was wondering; since the earth is spherical and the curvature is approximately 6 foot "drop" for every three miles i.e. a 6 foot person will disappear over the horizon 3 miles away, does a jet aircraft need to be constantly adjusted nose down to adjust for the curvature of the earth?

In other words, if a plane was trimmed for straight and level flight, would it "gain altitude" while flying as the earth surface "fell away" due to the curvature?

Thanks for your time and consideration.

Are twin turboprop engines as safe as twin jet engines planes?

TransAsia Airways ATR 72 Crash

Hi Capt Lim,

Are twin turboprop engines planes as safe as twin jet engines planes? Why is a loss of one turboprop engine resulted in an air crash?

Can we assume that a turboprop engine doesn’t have surplus power as much as jet engines aircraft?

Becoming a Pilot - The Inside Story

Hello there Captain!

It is nice to have the opportunity to send you an email! Well, I think I should introduce myself. I'm Glenn Gerald, currently 15 years old and I am from Sabah.

I bought your book 'Life in the Skies!' last December (2014) on my connecting flight from Kuala Lumpur to Vietnam and it was a fun and knowledgeable book for me. But sadly, I couldn't get your signature  However, on my flight from Kuala Lumpur to Kota Kinabalu I met two of the flight's First Officers and I was able to get their signatures.

Captain, if possible, I would like to meet you one day as it is one of my dreams to meet the one who inspired me the most  

I still remember the part of your flight from Shanghai to Kuala Lumpur on the Boeing 777. You cancelled your flight that day because of the typhoon!

You know? That story really touches my heart. I should be like you to think about other's safety especially the words, “when a doctor makes a mistake, only one patient dies, while a pilot’s mistake would impact the lives of hundreds.” I really love all of your words!

Captain, I am on my way to take my PT3 this year. For my next year's subject, I need to choose my subjects for my future.

Can I ask you Captain? What are the main subjects that I should take to be a pilot?

Sorry if I disturb you for a moment. Your reply will be much appreciated!

Sincerely,

GLENN GERALD
 
About engine thrust reverser and effect of rain water on jet engines
Written by Capt Lim

Jet Engine Thrust Reverser

Dear Captain Lim

My question is about thrust reversers - I am a light aircraft and glider pilot in the UK and I understand that when the thrust reversers are deployed on modern engines, the flaps cut off the direction of the air in the engine, the cowl opens and the air flow is directed forward.

Now when a commercial aircraft is landing, conventional wisdom dictates the engines should be at idle in the flare or very soon after touchdown. If this is the case, the fan blades will be wind-milling and not generating thrust, so why a need for reversers. The only reason I can think of when they must use them is, where engine power is above idle?

Does this mean that the engines are kept above idle in the flare so benefit of reversal can be achieved when the aircraft lands.

My final question - Why the rain water in the air doesn’t extinguish the combustion of a jet engine? Is it because the engine is too hot?

Many thanks

Regards

Simon

 
Does an airplane fly 3 degrees upwards or downwards during the cruise?
Written by Capt Lim

Angle of Attack and you

Hi Captain Lim

I have just finished reading a book about flying that I bought on a trip to Taiwan. From the book I know that an aircraft is flying at around 3 degrees when cruising in the air. I also know that the table on the passenger's seat is also designed to be at 3 degrees.

I have a question. Is the aircraft flying upwards at 3 degrees or downwards at 3 degrees? And if it flies upwards at 3 degrees, will it climb to a higher level? Flying from an opposite direction, would it descend at 3 degrees towards the ground?

Thank you for your answer.

Amelia
