1. A flight training assistant system comprising:
a notification unit;
a flight training assistant unit configured to communicate with the notification unit over a communications link, the flight training assistant unit comprising:
an aircraft mount configured for removably coupling to an attachment point of an aircraft;
a distance measurement device configured for measuring a distance of the distance measurement device above the ground;
a pitch sensor configured for measuring a pitch angle;
a roll sensor configured for measuring a roll angle;
a processor configured for:
calibrating the flight training assistant unit using measurements from the distance measurement device, the pitch sensor, and the roll sensor;
receiving measurements of the pitch angle and the roll angle;
determining a measured height of the aircraft above the ground based on measurements from the distance measurement device if the roll angle does not exceed a maximum allowed roll angle and the pitch angle does not exceed a maximum allowed pitch angle;
arming a descent mode if the measured height of the aircraft is determined to be more than a maximum height limit;
sending information regarding the measured height of the aircraft to the notification unit; and
sending an alert to the notification unit if the measured height of the aircraft is determined to be less than a maximum height limit and if the descent mode is armed and if the measured height of the aircraft is at a height setpoint or has crossed the height setpoint since last checked.
