Flying Into Non-Towered Airports

If you’re flying into or out of a non-towered airport, the FAA asks that you ‘play it safe’ and make radio calls if you’re equipped.

However, you aren’t required to do so.

What Do You Think?

Regulations can put strain on financial and regulatory freedom for pilots.

That being said, most rules are in place to keep pilots safe.

Should radio transmissions be required when operating to and from non-towered airports?

The word carburettor comes from the French word carbure, which means to combine with carbon.

In the context of aviation and automotive engines, a hydrocarbon is added to the airstream, thus increasing the energy content.

The carburettor on a petrol engine is where fuel gets added to the air in the correct ratio, which is predetermined by the design engineer.

A stoichiometric value of 14.7:1 (air to fuel) is said to be ideal for petrol engines.

This means for every 1 gram of fuel, you need 14.7 grams of air to have all the fuel burnt with no excess air.

Feedback from the WAA flight school

Notwithstanding the Covid-19 restrictions, 2020 was a good year of training for WAA .

Much of this was due to our foreign students.

A record period for us was from January 1, 2021 until May 10, 2021, where we completed more flight hours in that time than in an other whole year period.
