What is rule of thumb in aviation?

A rule of thumb is a principle with broad application that is not intended to be strictly accurate or reliable for every situation. It is an easily learned and easily applied procedure for approximately calculating some value.

What is the 50/70 rule in aviation?

So what is the 50/70 rule? It’s a general rule for GA aircraft that says if you haven’t reached 70% of your takeoff speed by the time you’ve reached 50% of the length of the runway, you should abort your takeoff. The winds might have changed prior to takeoff.

What do pilots have to check before take off?

Before taking off in any aircraft, pilots have to ensure the aircraft has been released by the maintenance engineers, complete visual inspections of the aircraft, test emergency and safety systems, configure the GPS and instrumentation, check the weather, routing, and weight & balance.

What are the rules of thumb for pilots?

Pilots are also aided with staying on top of things by the various rules of thumb. According to Wikipedia.com, a rule of thumb is “an easily learned and easily applied procedure for approximately calculating or recalling some value, or for making some determination.”.

What’s the rule of thumb for takeoff and landing?

Rule of thumb No. 5 states that a 10% change in weight will cause at least a 20% change in takeoff and landing distances. More weight requires more runway. This rule, too, has some variation in ground-roll numbers among aircraft.

What do you need to know to be a pilot?

Piloting an aircraft requires decision and precision. Quick references to the basics can make both easier. Pilots are expected to know lots of stuff. So it should come as no surprise that they like all the help they can get when memorizing, analyzing and calculating aviation concepts.

What happens to ground roll if you fly too fast?

A 10% change in groundspeed, which would be about five knots, brings forth an increase in ground roll of 25% (unmistakably more than the rule’s 20%). In general, though, if you fly too fast, you’ll land long. 5. 10/20 Rule Of Weight.
