That's why pilots are taught the 1 in 60 rule, which states that after 60 miles, a one-degree error in heading will result in straying off course by one mile. Which means the lake you planned to fly over could turn out to be a mountain.

A general rule of thumb for initial IFR descent planning in jets is the 3 to 1 formula. This means that it takes 3 NM to descend 1,000 feet. If an airplane is at FL 310 and the approach gate or initial approach fix is at 6,000 feet, the initial descent requirement equals 25,000 feet (31,000–6,000).
Basically the rule is that for every 60 miles travelled, 1 mile off track is equal to a track error of 1 degree. (eg if you have departed from point A and your planned track is 360 degrees, and at point B which is 60 miles from dep. you find yourself 1 mile right of track, your actual track has been 001 degrees.)
The Twelve-Five Standard Security Program (TFSSP) outlines requirements for FAA Part 135 certificated carriers offering commercial air transport using aircraft with a maximum certificated takeoff weight between 12,500 pounds (5,670 kg) and 100,309.3 pounds (45,500 kg).
You will need at least 20/20 distance vision without correction. This is because pilots are required to be able to see distant objects safely to ensure they can see and avoid them if necessary. But intermediate vision is less restrictive, at the 20/40 requirement.
Welcome – Long flightLadies and gentlemen, good morning / afternoon / evening. Welcome on board (flight reference). This is Captain / Co-pilot (your name) speaking and I have some information about our flight.
Standard takeoff minima are one statute mile for aircraft having two engines or less and one-half statute mile for aircraft having more than two engines. Specified ceiling and visibility minima will allow visual avoidance of obstacles during the initial climb at the standard climb gradient.
If a usable precision approach is available: 600' ceilings AND 2 SM of visibility. If only a non-precision approach is useable: 800' AND 2 SM of visibility. If no instrument approaches are available: Descent from the MEA and landing must be conducted under basic VFR.
1000 ft rule. An aircraft must maintain an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft over any congested area of a city, town, or settlement, or over any open air assembly of persons.
